| ○ | ○ | Review | Metal-organic frameworks composed of nitro groups: Preparation and applications in adsorption and catalysis | In this review, metal-organic frameworks functionalized with nitro groups (MOF-NO(2)s) were analyzed, for the first time, in terms of their preparation and applications. MOF-NO(2)s were obtained by direct synthesis from nitro-functionalized linker precursors and by post-synthetic modification of a pristine MOF without a -NO2 group. Additionally, the applications of MOF-NO(2)s, specifically in adsorption and catalysis, were discussed. CO2 capture using MOF-NO(2)s was highly effective due to the polar nitro group which aided in quadrupole-dipole interactions. Furthermore, on account of the electron-withdrawing nitro group, MOF-NO(2)s were efficient in the adsorption of other gases, such as nitrogen. Similarly, MOF-NO(2)s were promising for the removal of hazardous organics from water and particulate matter from the air mainly due to the charge separation on the nitro group. MOF-NO(2)s could be very useful in catalysis that relies on the Lewis acidity because the electron-withdrawing nitro group can increase Lewis acidity. MOF-NO(2)s can be used in other applications, such as detection of H2S. Based on the analysis of the achievements thus far, the prospects of MOF-NO(2)s for further research were provided. | Lee, Gyudong; Yoo, Dong Kyu; Ahmed, Imteaz; Lee, Hye Jin; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | LEE, HYEJIN/W-1345-2018; Jhung, Sung/AAO-6683-2021 | 57200987600; 57201339246; 55377179600; 56569175200; 6701659467 | sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 451 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 3.06 | 2025-06-25 | 93 | 90 | Adsorption; Catalysis; Detection; Electron-withdrawing group; Metal-organic framework; Nitro group | POROUS COORDINATION POLYMERS; LEWIS-ACID CATALYSIS; CO2 ADSORPTION; FUNCTIONAL-GROUPS; GAS-ADSORPTION; CARBON-DIOXIDE; LINKER SUBSTITUTION; OPTICAL-PROPERTIES; PORE WALL; MOFS | Adsorption; Catalysis; Detection; Electron-withdrawing group; Metal–organic framework; Nitro group | Catalysis; Metal-Organic Frameworks; Detection; Direct synthesis; Electron withdrawing group; Electronwithdrawing; Functionalized; Lewis acidity; Metalorganic frameworks (MOFs); Nitro group; Postsynthetic modification; Quadrupoles; Adsorption | English | 2023 | 2023-01-01 | 10.1016/j.cej.2022.138538 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Meticulous integration of N and C active sites in Ni2P electrocatalyst for sustainable ammonia oxidation and efficient hydrogen production | Ammonia, as an efficient hydrogen carrier, is emerging as an alternative energy resource to replace fossil fuels in the carbon-neutral era. Hydrogen production by water electrolysis seeks a lower potential dependent anodic reaction to overcome its energy-inefficiency that originates from the high potential anodic oxygen evolution reaction (OER). In this work, nickel phosphide supported on nitrogen doped-carbon (Ni2P@N-C) was prepared by one-pot synthesis for the bifunctional activity of hydrogen evolution (HER) and ammonia oxidation (AOR) re-actions. The Ni2P@N-C electrocatalyst exhibits about 78% decomposition of ammonia compared to the initial concentration. The amount of hydrogen generated in a 0.5 M ammonia environment for 30 min is about 2.144 mmol(H-2)/mol(NH3) h cm(2). The fabricated ammonia electrolysis cell demonstrates a comparatively low energy consumption rate of 8.611 KWHkg((H2))(-1). Thus, engineering a bifunctional electrocatalyst for a low potential anode oxidation reaction and the cathodic HER is a promising strategy to fabricate an energy efficient electrolysis cell for hydrogen production with a low cell potential requirement. | Jo, Chanmin; Surendran, Subramani; Kim, Min-Cheol; An, Tae-Yong; Lim, Yoongu; Choi, Hyeonuk; Janani, Gnanaprakasam; Jesudass, Sebastian Cyril; Moon, Dae Jun; Kim, Jaekyum; Kim, Joon Young; Choi, Chang Hyuck; kIM, Myeongjin; Kim, Jung Kyu; Sim, U.

| ○ | ○ | Article | Modeling sulfamethoxazole removal by pump-less in-series forward osmosis-ultrafiltration hybrid processes using artificial neural network, adaptive neuro-fuzzy inference system, and support vector machine | This study presented an in-series forward osmosis-ultrafiltration (FO-UF) hybrid system for sulfamethoxazole (SMX) removal. Artificial neural network (ANN), adaptive neuro-fuzzy inference system, and support vector machine were employed to predict water flux and SMX removals by FO and FO-UF. This investigation relied on 60 experimental data sets that varied the initial draw solution (DS) concentration (1-5 M), initial SMX concentration (2.5-12.5 mg/L), initial pH (3-11), and natural organic matter (NOM) content (0-18 mg/L as dissolved organic carbon). Experimental results demonstrated that the hybrid system achieved 83%-93% and 91%- 99% SMX removals via FO and FO-UF, respectively, while the obtained water flux was 5-14 L/m2h. From the three machine learning models, ANN had the most accurate prediction results, with statistical R2 of 0.96, 0.91 and 0.99 for water flux and SMX removals by FO and FO-UF, respectively. For the best ANN model, relative importance of the input variables to water flux and SMX removals by FO and FO-UF, respectively, was in the following order: DS concentration (41%, 49% and 36% in the aforementioned order), NOM concentration (21%- 28%), initial SMX concentration (15%-24%) and initial pH (11%-17%). | Nam, Seong-Nam; Yea, Yeonji; Park, Soyoung; Park, Chanhyuk; Heo, Jiyong; Jang, Min; Park, Chang Min; Yoon, Yeomin | Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Army Acad Yeongcheon, Mil Environm Res Ctr, 495 Hoguk Ro, Yeongcheon Si 38900, Gyeongsangbuk D, South Korea; Kwangwoon Univ, Dept Environm Engn, 20 Kwangwoon Rp, Seoul 01897, South Korea; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA | ; Park, Chang Min/CAA-8506-2022; Yoon, Yeomin/KDP-2253-2024; Nam, Seong-Nam/ABT-9415-2022; Park, Chanhyuk/A-2577-2013; Jang, Min/J-2230-2012 | 57226757907; 57217304205; 58180532500; 56140966600; 42461338400; 36762550700; 57209588953; 7402126688 | cmpark@knu.ac.kr;yoony@cec.sc.edu; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 474 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.35 | 2025-06-25 | 11 | 14 | Machine learning; Neural network; Membrane filtration; Pharmaceutical contaminant | PHOTOCATALYTIC DEGRADATION; FLUX BEHAVIOR; OPTIMIZATION; ADSORPTION; PREDICTION | Machine learning; Membrane filtration; Neural network; Pharmaceutical contaminant | Fuzzy inference; Fuzzy neural networks; Fuzzy systems; Hybrid systems; Learning systems; Microfiltration; Organic carbon; Ultrafiltration; Adaptive neuro-fuzzy inference; Forward osmosis; Machine-learning; Membrane filtrations; Network adaptive; Neural-networks; Neuro-fuzzy inference systems; Pharmaceutical contaminants; Sulfamethoxazole; Water flux; Support vector machines | English | 2023 | 2023-10-15 | 10.1016/j.cej.2023.145821 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Novel double Z-scheme g-C3N5/BiFeO3/ZnIn2S4 heterojunction system with enhanced visible-light-induced photo-Fenton activity towards sulfamethoxazole degradation | In this study, a novel double Z-scheme g-C3N5/BiFeO3/ZnIn2S4 (CBZ) heterojunction nanocomposite was synthesized using a simple wet chemical process. The crystal structure, morphology, optical, and chemical compositional behaviors of the prepared nanocomposite were characterized using various techniques. The Vis/ H2O2/CBZ-40% system could remove 97% sulfamethoxazole (SMX) pollutant for 60 min. The significantly enriched performance was attributed to the greater Fe2+/Fe3+ conversion efficiency by decomposing H2O2, and the synergistic coupling of the CBZ-40% in ternary heterojunction provided a better charge transfer pathway for the initiation of photo-Fenton reactions. In addition, the trapping experiments and electron spin resonance analysis identified active reactive oxygen species such as & BULL;OH, & BULL;O2 , and 1O2. The possible degradation mechanism of SMX and their intermediate products were proposed based on the above experimental analysis. Moreover, this results showed the suitability of using Vis/H2O2/CBZ-40% system, providing excellent reusability and an admissible platform for wastewater remediation via double Z-scheme heterojunction. | Jagan, Govindan; Saravanakumar, Karunamoorthy; Li, Jianbing; Yoon, Yeomin; Park, Chang Min | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ Northern British Columbia, Environm Engn Program, Prince George, BC V2N 4Z9, Canada; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea | Yoon, Yeomin/KDP-2253-2024; Karunamoorthy, Saravanakumar/Q-2005-2016; Park, Chang Min/CAA-8506-2022 | 57885044400; 57223020778; 57218474538; 7402126688; 57209588953 | cmpark@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 471 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 4.9 | 2025-06-25 | 54 | 52 | Double Z-scheme; Photo-Fenton reaction; BiFeO3; Sulfamethoxazole | PHOTOCATALYST | BiFeO<sub>3</sub>; Double Z-scheme; Photo-Fenton reaction; Sulfamethoxazole; ZnIn<sub>2</sub>S<sub>4</sub> | Bismuth compounds; Charge transfer; Conversion efficiency; Crystal structure; Degradation; Heterojunctions; Image enhancement; Iron compounds; Magnetic moments; Nanocomposites; Oxidation; Reusability; Crystals structures; Double Z-scheme; Fenton activity; Photo-Fenton; Photo-Fenton reactions; Simple++; Sulfamethoxazole; Synthesised; Visible light induced; Wet chemical process; Zinc compounds | English | 2023 | 2023-09-01 | 10.1016/j.cej.2023.144707 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | paper Strong inhibition of organic cation transporter 2 by flavonoids and attenuation effects on cisplatin-induced cytotoxicity | Organic cation transporter 2 (OCT2) is predominantly expressed in the basolateral membrane of renal proximal tubule cells and contributes to the renal excretion of various drugs such as metformin, cisplatin, oxaliplatin, cimetidine, and lamivudine. Cisplatin, an anticancer agent for various cancers, is a substrate of OCT2, and cisplatin-induced nephrotoxicity is in part attributed to OCT2 activity in the kidney, which increases the renal accumulation of cisplatin. In this study, we aimed to identify flavone derivatives with strong inhibitory effects on OCT2 transport. Among the 80 flavonoids tested, 24 showed moderate to strong inhibitory effects against OCT2 transport activity. The IC50 values were less than 5 mu M for 10 flavonoids. All 10 compounds alleviated cisplatin-induced cytotoxicity in cells expressing OCT2, even though the magnitude of the effects varied depending on the functional moieties in each position. Multiple factor analysis revealed that the methyl group at the R1 position and methoxy group at the R6 position of the flavonol backbone are important for OCT2 inhibition. Information on the functional moieties in the flavonol backbone would help develop effective OCT2 inhibitors by providing a structural association with OCT2 inhibitory effects. In addition, the compounds with strong inhibitory effects on OCT2 identified in this study may be potential candidates for clinical use to mitigate cisplatin-induced nephrotoxicity. | Shin, Kwang-Hee; Lee, Kyeong-Ryoon; Kang, Min-Ji; Chae, Yoon-Jee | Kyungpook Natl Univ, Coll Pharm, Res Inst Pharmaceut Sci, Daegu 41566, South Korea; Korea Res Inst Biosci & Biotechnol, Lab Anim Resource Ctr, Cheongju 28116, South Korea; Univ Sci & Technol, Dept Biosci, Daejeon 34113, South Korea; Woosuk Univ, Coll Pharm, Res Inst Pharmaceut Sci, Wonju 55338, South Korea | 35216279300; 35409534300; 58195281200; 53463158200 | yjchae@woosuk.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 379 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 0.65 | 2025-06-25 | 4 | 4 | Organic cation transporter 2; Flavonoids; Cisplatin; Nephrotoxicity; Multiple factor analysis | OCT2; NEPHROTOXICITY; INVOLVEMENT; MECHANISMS; QUERCETIN; THERAPY; CANCER; CARBOPLATIN; OXALIPLATIN; COMBINATION | Cisplatin; Flavonoids; Multiple factor analysis; Nephrotoxicity; Organic cation transporter 2 | Cisplatin; Flavonoids; Flavonols; Organic Cation Transport Proteins; Organic Cation Transporter 2; cimetidine; cisplatin; flavone; flavonoid; flavonol; lamivudine; metformin; organic cation transporter 2; oxaliplatin; cisplatin; flavonoid; flavonol derivative; organic cation transporter; organic cation transporter 2; Article; basolateral membrane; cell culture; cell density; cell viability; controlled study; cytotoxicity; cytotoxicity assay; fluorescence intensity; MDCK cell line; MTT assay; nephrotoxicity; nonhuman; proximal tubule cell; urinary excretion | English | 2023 | 2023-04-26 | 10.1016/j.cbi.2023.110504 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Performance of wild, tailed, humidity-robust phage on a surface-scanning magnetoelastic biosensor for Salmonella Typhimurium detection | A wild, tailed phage (TST) was compared with a genetically modified, filamentous phage (FST) for S. Typhi-murium (ST) detection. When both phages were introduced into oppositely charged MUA and MUAM sensors, the RU values of TST showed an obvious increase on the MUAM sensor. The sensitivity of TST [54.78 ARU/(log PFU/mL)] was greater than that of FST [48.05 ARU/(log PFU/mL)]. The binding affinity (KD = 1.75 x 10-13 M) of TST on MUAM sensor was greater than that of FST. Both phages were specific to only ST, and TST exhibited a persistent binding capability at 50 % RH. When each phage-immobilized sensor was employed on chili pepper, the sensitivity [880.80 Hz/(log CFU/mL)] and detection limit (1.31 +/- 0.27 log CFU/mL) of TST were signifi-cantly greater than those of FST. The orientation of TST on sensor promoted the uniform capture of bacteria and enhanced the reliable performance of a surface-scanning magnetoelastic biosensor. | Lee, Hwa-Eun; Jeon, Yu -Bin; Chin, Bryan A.; Lee, Sang Hyuk; Lee, Hye Jin; Park, Mi- Kyung | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Food & Bioind Res Inst, Daegu 41566, South Korea; Auburn Univ, Mat Res & Educ Ctr, Dept Mat Engn, Auburn, AL 36849 USA; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Park, Mi-Kyung/J-9643-2017 | 57218564113; 58037452600; 24529688800; 55188583800; 56569175200; 7404491155 | parkmik@knu.ac.kr; | FOOD CHEMISTRY | FOOD CHEM | 0308-8146 | 1873-7072 | 409 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY;NUTRITION & DIETETICS | 2023 | 8.5 | 3.1 | 1.23 | 2025-06-25 | 10 | 10 | Tailed phage; Filamentous phage; Binding interaction; Surface -scanning coil; A f measured; AfSEM | RESISTANT STAPHYLOCOCCUS-AUREUS; LYTIC PHAGE; WATER | Binding interaction; Filamentous phage; Surface-scanning coil; Tailed phage; Δf<sub>measured</sub>; Δf<sub>SEM</sub> | Bacteriophages; Biosensing Techniques; Capsicum; Humidity; Salmonella typhimurium; Bacteriophages; Biosensors; Salmonella; Binding interaction; Filamentous phage; Magnetoelastics; Performance; S. typhimurium; Surface scanning; Surface-scanning coil; Tailed phage; Δfmeasured; ΔfSEM; Article; bacteriophage; binding affinity; humidity; limit of detection; nonhuman; pepper; Salmonella enterica serovar Typhimurium; genetic procedures; genetics; humidity; pepper; Salmonella enterica serovar Typhimurium; Binding energy | English | 2023 | 2023-05-30 | 10.1016/j.foodchem.2022.135239 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Polyelectrolyte-silica composite quorum quenching biomedia as new antifouling agents for anaerobic membrane bioreactor treatment | Anaerobic membrane bioreactors (AnMBRs) have received increasing attention because of their low energy requirements; however, membrane fouling is the major deterrent to their widespread application. Here, we report a novel composite biomedium composed of quorum quenching (QQ) bacteria (Rhodococcus sp. BH4), porous silica, and polyelectrolytes for biofouling control in AnMBRs. The facultative character of BH4 is described for the first time, showing its QQ activity (the pseudo-first-order rate constant of degradation of Noctanoyl-L-homoserine lactone, 15.3-16.3 h-1) and biofilm inhibition (33-44 % reduction compared to the control) under anaerobic conditions. The results showed that the composite QQ media caused a significant delay in AnMBR membrane fouling (>2.5 and 1.9 times, respectively) compared to the cases with no or vacant media. The QQ media maintained >90 % of its original tensile strength after 40 days of use in the AnMBR, exhibiting more excellent durability than hydrogel-based media. QQ media contributed to the reduced production of biopolymers (e.g., proteins) and signal molecules (e.g., short- and medium-chain acyl-homoserine lactones) in the AnMBR. Finally, the QQ media did not impact anaerobic treatment performance, such as organic removal or methane production. The findings of this study demonstrate the QQ efficacy and sustainability of the BH4 strain and its composite media in AnMBRs. | Shah, Syed Salman Ali; Park, Hyeona; Park, Hyung-June; Kim, Jinwoo; Angelidaki, Irini; Lee, Changsoo; Kim, Jeonghwan; Choo, Kwang-Ho | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, 80 Daehak ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Inst Water Ind, 80 Daehak ro, Daegu 41566, South Korea; Tech Univ Denmark, Dept Chem & Biochem Engn, DK-2800 Lyngby, Denmark; Ulsan Natl Inst Sci & Technol UNIST, Dept Urban & Environm Engn, 50 UNIST gil Ulju gun, Ulsan 44919, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Grad Sch Carbon Neutral, 50 UNIST gil Ulju gun, Ulsan 44919, South Korea; Inha Univ, Dept Environm Engn, 100 Inha ro, Incheon 22212, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak ro, Daegu 41566, South Korea | ; Choo, Kwang-Ho/A-3456-2016; Shah, Syed Salman Ali/JCE-1663-2023; Angelidaki, Irini/AAX-2562-2020 | 57215722996; 57213039681; 57213039678; 57901150400; 6603674728; 56404735500; 57214338786; 7102083272 | chookh@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 452 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.44 | 2025-06-25 | 13 | 15 | Anaerobic membrane bioreactors; Biofouling control; Porous silica; Polyelectrolyte; Quorum quenching | DOMESTIC WASTE-WATER; BIOFOULING CONTROL; FOULING MECHANISMS; ENERGY-CONSUMPTION; BACTERIA; PERFORMANCE; FLUX | Anaerobic membrane bioreactors; Biofouling control; Polyelectrolyte; Porous silica; Quorum quenching | Amino acids; Bioconversion; Biofouling; Bioreactors; Esters; Membrane fouling; Membranes; Polyelectrolytes; Quenching; Rate constants; Surface treatment; Tensile strength; Anaerobic membrane bioreactor; Antifouling agents; Bio-media; Biofouling control; Homoserine lactones; Lower energies; Porous silica; Quenching media; Quorum quenching; Silica composites; Silica | English | 2023 | 2023-01-15 | 10.1016/j.cej.2022.139568 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Recovery of rare-earth and radioactive elements from contaminated water through precipitation: A review | Recovery of rare-earth elements (REEs) and radioactive elements have become an important issue because they are precious materials for economic growth, environmental protection, and national security. This study provides a comprehensive review of precipitation processes for the recovery of REEs and radioactive elements according to precipitant type and precipitation mechanism. The optimal recovery performance of these approaches varies with several water quality factors, namely, solution pH, dissolved oxygen, temperature, the presence of co-ions, ionic strengths, the initial concentration of target elements, and the presence of organic substances (e.g., humic acids). For instance, an interesting phenomenon was observed when U(VI) was reductively precipitated by ferrous ion under high-O2 conditions, since precipitated U(IV) on iron surfaces reoxidized during groundwater remediation when it is exposed to O2. These optimal recovery performance and its precipitation mechanisms are clarified via three main characterization approaches: (i) optical and electron microscopy approaches, (ii) X-ray diffraction-based approaches, and (iii) spectroscopy approaches. These characterization methods are complementary and can enhance the reliability of precipitation mechanisms. Lastly, a concise overview is provided regarding the complex systems and potential research challenges of the precipitation process for the recovery of REEs and radioactive elements, based on the fact that complex recovery systems could be optimized by consideration of mass-balance calculations, economical assessment, timescale, and redox sources from an engineering perspective. | Jun, Byung-Moon; Kim, Hak-Hyeon; Rho, Hojung; Seo, Jiwon; Jeon, Jin-Woo; Nam, Seong-Nam; Park, Chang Min; Yoon, Yeomin | Korea Atom Energy Res Inst, Radwaste Management Ctr, 111 Daedeok Daero 989beon gil, Daejeon 34057, South Korea; Univ Waterloo, Dept Civil & Environm Engn, Waterloo, ON N2L 3G1, Canada; Korea Inst Civil Engn & Bldg Technol, Dept Environm Res, 283 Goyang Daero, Goyang 10223, Gyeonggi Do, South Korea; Korea Basic Sci Inst, Div Mat Anal & Res, Gwahak ro, Daejeon 34133, South Korea; Agcy Def Dev, Chem Bio Technol Ctr, POB 35, Daejeon 34186, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae gil, Seoul 03760, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak ro, Daegu 41566, South Korea; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA | Jun, Byung-Moon/Y-2134-2019; Park, Chang Min/CAA-8506-2022; Nam, Seong-Nam/ABT-9415-2022; Kim, Hak-Hyeon/ABE-1614-2021; Rho, Hojung/AAZ-5517-2020; Yoon, Yeomin/KDP-2253-2024 | 55326699900; 56683717600; 57196479406; 58678466200; 57190015905; 57226757907; 57209588953; 7402126688 | yoony@cec.sc.edu; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 475 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.01 | 2025-06-25 | 27 | 28 | Precipitation; Recovery; Rare-earth and radioactive elements; Water treatment | AQUEOUS-SOLUTION; WASTE-WATER; REDUCTIVE PRECIPITATION; NANOFILTRATION MEMBRANES; SULFURIC-ACID; ION-EXCHANGE; URANIUM; REMOVAL; ADSORPTION; U(VI) | Precipitation; Rare-earth and radioactive elements; Recovery; Water treatment | Biochemical oxygen demand; Dissolution; Dissolved oxygen; Economics; Groundwater; Groundwater pollution; Ionic strength; National security; Precipitation (chemical); Rare earth elements; Rare earths; Water quality; Water treatment; Co ions; Contaminated water; Economic growths; Initial concentration; Optimal recovery; Precipitation mechanism; Precipitation process; Recovery performance; Solution pH; Water quality factor; Recovery | English | 2023 | 2023-11-01 | 10.1016/j.cej.2023.146222 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Remediation of ciprofloxacin in soil using peroxymonosulfate activated by ball-milled seaweed kelp biochar: Performance, mechanism, and phytotoxicity | This study explores the catalytic performance of simple physically modified ball-milled kelp-seaweed (Laminaria japonica) biochar (KBCBM) for organic degradation in the soil. The present study is the first attempt at CIPcontaminated soil (CIPsoil) remediation using KBCBM with peroxymonosulfate (PMS) and exploring the phytotoxicity of the intermediates in the treated soil. The surface characterization of the KBCBM catalyst was investigated using different instrumental analyses. The CIPsoil/KBCBM/PMS system showed excellent performance in CIP degradation (96.06%, C0 = 126.15 +/- 0.7 mg kg- 1) under the conditions of 1.0 mM PMS, 1.5 mg g- 1 of KBCBM and unadjusted pH (6.3) condition. The co-existing anions: such as Cl-, HCO3-, and HPO42- enhanced the CIP degradation in the CIPsoil/KBCBM-800/PMS system. However, SO42-, NO3- , and organic matter (HA) showed negligible impacts on pollutant degradation in the KBCBM/PMS system. Reactive oxygen species (ROS) formation was confirmed by chemical scavengers and electron spin resonance spectroscopy (ESR) analysis. The non-radical reaction pathway was verified by electrochemical analysis of linear sweep voltammetry (LSV) and potentiodynamic testing (i-t curve) methods in the KBCBM/PMS. In addition, the phytotoxicity analysis was evaluated by the germination percentage of cucumber seeds with and without remediated soil. The possible CIP degradation mechanisms were proposed using UPLC-MS/MS analysis. The KBCBM/PMS system demonstrated encouraging capabilities in the treatment of CIP-contaminated soil. | Al Masud, Md Abdullah; Annamalai, Sivasankar; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | ; Annamalai, Sivasankar/G-7823-2016; Masud, Md Abdullah Al/JEF-1055-2023 | 57542255300; 56388546200; 23019870800 | wshin@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 465 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 4.81 | 2025-06-25 | 46 | 51 | Ball-milled kelp biochar | PERSISTENT FREE-RADICALS; CARBON NANOTUBES; ORGANIC CONTAMINANTS; DEGRADATION; OXIDATION; PYROLYSIS; REMOVAL; WATER | Ball-milled kelp biochar; Ciprofloxacin; Oxidation kinetics; Phytotoxicity; Singlet oxygen; Soil remediation | Antibiotics; Degradation; Electron spin resonance spectroscopy; Free radicals; Magnetic moments; Oxygen; Reaction kinetics; Remediation; Seaweed; Soil conservation; Soil pollution; Ball-milled; Ball-milled kelp biochar; Biochar; Ciprofloxacin; Contaminated soils; Oxidation kinetics; Peroxymonosulfate; Phytotoxicity; Singlet oxygen; Soils remediation; Soils | English | 2023 | 2023-06-01 | 10.1016/j.cej.2023.142908 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Review of boron nitride-based membranes in liquid purification/separation applications | Boron nitride (BN) has been drawing significant interest in environmental applications owing to its distinct properties, such as a large surface area, great chemical/ mechanical strength, and abundant structural defects. BN-based membranes have been utilized in various liquid purification/separation applications associated with reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF). A small number of review studies have been published on the environmental applications of BN-based membranes, including water purification and desalination. However, further studies are vital to gain the comprehensive understanding needed to assess the removal/separation mechanisms in BN-based membranes, although existing reviews cover the water desalination, antibacterial performance, and/or energy applications of BN-based membranes. Therefore, in this review, we provide an overview of the various types of BNs (e.g., functionalized BN nanosheets, nanotubes, and nanofibers) incorporated into RO, NF, and UF membranes. Next, we discuss the fabrication and separation performance of various BN-based membranes. In particular, this review focuses on various main factors, namely, the fabrication techniques of BN-based membranes, membrane physicochemical properties, and contaminant properties that affect the transport, separation, and membrane flux during the use of BN-based membrane processes. Finally, prospective study areas are presented briefly. | Nam, Seong-Nam; Park, Chang Min; Jang, Min; Huang, Yi; Jang, Am; Son, Ahjeong; Yoon, Yeomin | Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kwangwoon Univ, Dept Environm Engn, 447-1 Wolgye Dong, Seoul, South Korea; Univ Edinburgh, Sch Engn, Inst Mat & Proc Imp, Colin Maclaurin Rd, Edinburgh EH9 3DW, Midlothian, Scotland; Sungkyunkwan Univ, Sch Civil & Architecture Engn, 2066 Seobu Ro,Jangan 16 Gu, Suwon 16419, Gyeonggi Do, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea | Son, Ahjeong/AAV-7000-2021; Yoon, Yeomin/KDP-2253-2024; Jang, Min/M-6690-2018; Park, Chang Min/CAA-8506-2022; HUANG, Yi/G-3405-2011; Jang, Min/J-2230-2012; Nam, Seong-Nam/ABT-9415-2022 | 57226757907; 57209588953; 36762550700; 55717272000; 7004582729; 23487252600; 7402126688 | ason@ewha.ac.kr;yoony@cec.sc.edu; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 453 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 2.02 | 2025-06-25 | 20 | 21 | WASTE-WATER TREATMENT; NATURAL ORGANIC-MATTER; NANOCOMPOSITE NANOFILTRATION MEMBRANES; ENDOCRINE DISRUPTING COMPOUNDS; ULTRAFILTRATION MEMBRANES; REVERSE-OSMOSIS; CARBON NANOTUBES; REMOVAL; PHARMACEUTICALS; GRAPHENE | Desalination; III-V semiconductors; Nitrides; Osmosis membranes; Physicochemical properties; Purification; Reverse osmosis; Water filtration; Antibacterial performance; Environmental applications; Large surface area; Mechanical; Performance and applications; Property; Separation mechanism; Structural defect; Water desalination; Water purification; Boron nitride | English | 2023 | 2023-02-01 | 10.1016/j.cej.2022.139740 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Ru/K2CO3-MgO catalytic sorbent for integrated CO2 capture and methanation at low temperatures | In this study, we have developed a Ru/K2CO3-MgO (Ru/KMg) catal-sorbent for integrated CO2 capture and methanation (ICCM) at low temperatures. The Ru primarily existed as a K2RuO3 phase, which was not observed after reduction at 400 degrees C. In addition, the crystallite size of Ru0 is smaller than that of Ru/MgO because Ru species as K2RuO3 phase, instead of RuO2, is dispersed well throughout the MgO support material. Here, the CO2 capture and regeneration properties of Ru/KMg catal-sorbents after carbonation at different temperatures (60, 120, 150, and 320 degrees C) were studied under N2 or H2 conditions, respectively. The optimal carbonation temper-ature was 150 degrees C when considering 100% CO2 conversion to CH4. 20 consecutive cycles of ICCM were conducted at 150 degrees C for carbonation (10 vol% CO2 and 10 vol% H2O) and 320 degrees C for methanation (90 vol% H2). The results showed stable CH4 productivities of 1.07-1.19 mmol CH4/g with 100% CH4 selectivity and 96.2%-101.3% CH4 yield. | Jo, Seongbin; Son, Han Dong; Kim, Tae-Young; Woo, Jin Hyeok; Ryu, Do Yeong; Kim, Jae Chang; Lee, Soo Chool; Gilliard-AbdulAziz, Kandis Leslie | Univ CA Riverside, Dept Chem & Environm Engn, Riverside, CA 92521 USA; Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; JnK Co Ltd, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; Univ CA Riverside, Dept Mat Sci & Engn, Riverside, CA 92521 USA | Jo, SeongBin/MFJ-9000-2025; Kim, Yu/L-8480-2017 | 57190754848; 58307056400; 57208461628; 57215492471; 57409454800; 55382762400; 8524020100; 57200598917 | kjchang@knu.ac.kr;soochool@knu.ac.kr;klabdulaziz@engr.ucr.edu; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 469 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 2.12 | 2025-06-25 | 24 | 24 | IntegratedCO2 capture and methanation; (ICCM); Ru; KMg catal-sorbent; Dispersion; CH4 yield | SOLID SORBENTS; NANOPARTICLES; ADSORPTION; GREEN | CH<sub>4</sub> yield; Dispersion; Integrated CO<sub>2</sub> capture and methanation (ICCM); Ru/KMg catal-sorbent | Crystallite size; Hydrogenation; Magnesia; Methanation; Ruthenium; Ruthenium compounds; Sorbents; Sorption; % reductions; 150 ° C; CH 4; CH4 yield; Integrated CO2 capture and methanation; Lows-temperatures; MgO; Ru species; Ru/K2CO3–MgO catal-sorbent; Support materials; Carbon dioxide | English | 2023 | 2023-08-01 | 10.1016/j.cej.2023.143772 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Smart microsubmarine shells operated by controlled buoyancy force through metal-ion adsorption/desorption and their biosensor applications | Small and uniform-sized poly(polyethylene glycol (PEG)-co-acrylic acid (AA)) shells engulfing a mineral oil droplet (oil@poly(PEG-co-AA) shells, similar to 180 mu m) are prepared using the in situ polymerization of the O(mineral oil)-W(PEGDA/AA, PEGDA = polyethylene glycol diacrylate)-O(mineral oil) double emulsion droplets produced in a microfluidic chip. The lightweight oil core and heavy-weight poly(PEG-co-AA) shells exhibit positive buoyancy and negative gravitational forces in water, respectively. Densities of oil@poly(PEG-co-AA) shells were finely tuned in water to be sensitive to a small weight change by controlling microfluidic parameters. The poly (PEG-co-AA) shells are pH-responsive in terms of charged state and shell size. The pH-controlled metal adsorption/desorption at poly(PEG-co-AA) shells breaks the density balance, leading to the sinking or floating of oil@poly(PEG-co-AA) shells in the water. Herein, this levitation and size change of oil@poly(PEG-co-AA) shells are applied to glucose and urea biosensors by immobilizing their enzymes. The divalent (or higher) metal adsorption is distinguishable from monovalent metal adsorption by the diminished size of the oil@poly(PEG-coAA) shells and their different levitation behavior in water. Thus, these oil@poly(PEG-co-AA) shells facilitate smart motile sensor applications with an unexplored concept, which can be further expanded to other applications such as smart valves in microfluidics and smart windows. | Tan, Hao; Park, Soo-Young | Kyungpook Natl Univ, Dept Polymer Sci & Engn, Polymer Nano Mat Lab, Daegu 41566, South Korea | park, soo-young/N-3170-2017 | 56895457900; 57194041850 | psy@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 473 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 0.29 | 2025-06-25 | 3 | 3 | Hydrogel; Microfluidics; Biosensor; Levitation; Submarine; Metal-ion | CHOLESTERIC LIQUID-CRYSTALS; GRAFTING DENSITY; DOUBLE EMULSIONS; ACID); COMPLEXES; DROPLETS; BEHAVIOR; SURFACE | Biosensor; Hydrogel; Levitation; Metal-ion; Microfluidics; Submarine | Adsorption; Amines; Ascorbic acid; Biosensors; Drops; Emulsification; Emulsions; Iron oxides; Microfluidics; Minerals; Polyethylene glycols; Polyethylenes; Shells (structures); Urea; Acrylic acids; Adsorption/desorption; Biosensors applications; Buoyancy forces; Levitation; Metal adsorption; Metal ion adsorption; Metals ions; Oil droplets; Uniform-sized; Metal ions | English | 2023 | 2023-10-01 | 10.1016/j.cej.2023.145219 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Thermo-Viscoelastic residual stress behavior of fluorinated polyimide based on fluid Instability-Driven shear exfoliated graphenic nanosheet | Attempts to reduce the size of electronic devices result in residual stresses in the polymeric optoelectronic materials used therein, leading to detrimental effects such as microscopic defect formation and macroscopic dimensional changes. In this study, fluorinated polyimide (FPI) reinforced with reduced graphene oxide (RGO) was fabricated by exploiting the instability of the Taylor -Couette flow. This method affords exceptional ul-tralow residual stresses. High fluid-wall shear stress in Taylor vortex flow (TVF) with axisymmetric instability accelerates the reduction of graphene oxide (GO) even at a low temperature of 85 degrees C. Using ascorbic acid as a green reducing agent, a highly exfoliated RGO@TVF nanohybrid was obtained, which activated the interaction at the polymer-filler interface. During high-temperature cycling, real-time residual stress-temperature profiles generated at the interface between the FPI/RGO@TVF nanohybrid films and Si wafer substrate were analyzed. The results demonstrated that the residual stress strongly depends on the processing temperature and micro-structure and that the stress eventually converges to a zero-stress value (<7 MPa) even at a low RGO@TVF loading of 3 wt%. In addition, the incorporation of RGO@TVF into the FPI resulted in nanohybrid films with a high storage modulus (2126 MPa) and glass transition temperature (330 degrees C). The results show that the highly exfoliated RGO@TVF provides more contact points between the polyimide chains and RGO@TVF sheets, which increases the polymer-filler compatibility, thereby improving the thermal and dimensional stability. | Hwang, Yun Chan; Khim, Seongjun; Nam, Ki-Ho | Kyungpook Natl Univ, Dept Text Syst Engn, Daegu 41566, South Korea | 58023979900; 58024968200; 55553181500 | knam@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 455 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 0.1 | 2025-06-25 | 2 | 1 | Fluorinated polyimide; Reduced graphene oxide; Taylor-Couette flow; Residual stress | THERMAL-EXPANSION; TRANSPARENT; FILMS; FUNCTIONALIZATION; COEFFICIENT; COVALENT; COLORLESS; GRAPHITE; HISTORY; OXIDE | Fluorinated polyimide; Reduced graphene oxide; Residual stress; Taylor−Couette flow | Ascorbic acid; Curing; Glass transition; Graphene; Shear stress; Silicon wafers; Stress analysis; Vortex flow; Electronics devices; Fluid instability; Fluorinated polyimides; Nano-hybrid film; Optoelectronic materials; Reduced graphene oxides; Stress behavior; Taylor Couette flow; Taylor Vortex flow; Thermo-viscoelastic; Temperature | English | 2023 | 2023-01-01 | 10.1016/j.cej.2022.140888 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Utilizing waste carbon residue from spent lithium-ion batteries as an adsorbent for CO2 capture: A recycling perspective | Recycling and reusing the carbon-residues (i.e., graphite), as well as recovering valuable metals by leaching from spent lithium-ion batteries, is environmentally and economically significant. In particular, since a large amount of spent lithium-ion batteries (LIBs) will be generated along with the rapid growth of electric vehicles (EVs), research on recycling carbon-residues from LIB anodes is urgently needed. Herein, the battery powder (BP) was obtained from spent lithium-ion batteries (LIBs) through physical-pyrolysis and sieving. Chemical composition analysis confirmed that the battery used in this work was composed of NCM cathode with high-nickel content and graphite anode material. The average particle size of the obtained BP was 87 & mu;m. In order to obtain the residue having high concentration of carbon, the metal extraction was applied using an HCl solution. As a result, metals (Li, Ni, Co, Mn, Al, Cu, and Fe) in the final remnant were found to be less than 2%, and carbon was found to have a purity of 97% or more. The obtained BP was tested as both the adsorbent and support for indoor CO2 capture. Various activation treatments were examined to enhance the textural properties of BP. BP-K (K2CO2 impregnated BP) adsorbents were prepared, and their CO2 adsorption performances were evaluated with CO2 adsorption isotherms, thermogravimetric analysis (TGA), and 0.1 m3 chamber (CO2 IR analyzer) at low CO2 level (1000-2000 ppm). Through XRD and FT-IR analyses, the adsorption mechanism between K2CO3 and CO2 under moisture-containing indoor air conditions was confirmed to depend on chemisorption in the following reaction pathway: R1-R3(K2CO3(s) + H2O (g) + CO2 (g) ' 2KHCO3(s) (R1), K2CO3(s) + 1..5H2O(g) ' K2CO3.1..5H2O(s) (R2), K2CO3.1..5H2O(s) + CO2(g) ' 2KHCO3(s) + 0..5H2O(g)(R3)). The adsorption working capacities of the recycled BP-K adsorbents were remained relatively constant during four consecutive cycles. | Lee, Yu-Ri; Cho, A.

| ○ | ○ | Article | Virtuous utilization of carbon dioxide in pyrolysis of polylactic acid | Polylactic acid has been adopted as a strategic alternative to petroplastics because of its biodegradability. The waste generation rate could be proportional to its use, considering the short lifespan of polylactic acid. However, a practical disposal or recycling protocol for polylactic acid waste has not yet been developed. Thus, this study suggests a promising thermochemical platform for valorizing polylactic acid waste into energy resources (syngas). Specifically, carbon dioxide-assisted pyrolysis has been suggested to impart environmental features to polylactic acid disposal. Before the pyrolysis tests, the polylactic acid waste sample was characterized by Fourier transform-infrared spectrometer and thermogravimetric analyses, which showed that polylactic acid contained a substantial amount of additives and impurities (similar to 13 wt%). The impurity containing polylactic acid was converted into pyrogenic gases and biocrudes through pyrolysis process. The pyrolysis was performed under carbon dioxide condition and led to enhanced carbon monoxide formation from simultaneous homogeneous reactions between CO2 and volatile organic compounds evolved from thermal degradation of polylactic acid. CO2 was reduced and the volatile compounds were oxidized. The evolution of carbon monoxide from pyrolysis under carbon dioxide condition was 2 times higher than that from nitrogen condition. The concentration of carbon monoxide from the pyrolysis of polylactic acid waste with respect to plastics and biomass was considerably higher. This observation indicates that the susceptibility of carbon dioxide to the homogeneous reaction is highly sensitive. To seek a way to hasten the homogeneous reaction, silica supported nickel catalysts were applied. The evolution of carbon monoxide from catalytic pyrolysis under carbon dioxide condition was 4.5 times higher than inert atmosphere. | Cho, Seong-Heon; Kim, Youkwan; Lee, Sangyoon; Lin, Kun-Yi Andrew; Chen, Wei-Hsin; Jung, Sungyup; Lee, Doyeon; Moon, Deok Hyun; Jeon, Young Jae; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Natl Chung Hsing Univ, Dept Environm Engn, Kuo Kuang Rd, Taichung 250, Taiwan; Natl Chung Hsing Univ, Innovat & Dev Ctr Sustainable Agr, Kuo Kuang Rd, Taichung 250, Taiwan; Natl Cheng Kung Univ, Dept Aeronaut & Astronaut, Tainan 701, Taiwan; Tunghai Univ, Res Ctr Smart Sustainable Circular Econ, Taichung 407, Taiwan; Natl Chin Yi Univ Technol, Dept Mech Engn, Taichung 411, Taiwan; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Hanbat Natl Univ, Dept Civil & Environm Engn, Daejeon 34158, South Korea; Chosun Univ, Dept Environm Engn, Gwangju 61452, South Korea; Pukyong Natl Univ, Dept Microbiol, Busan 48513, South Korea; Pukyong Natl Univ, Sch Marine & Fisheries Life Sci, Busan 48513, South Korea | Chen, Wei-Hsin/S-2033-2018; Jung, Sungyup/ABE-1493-2021; Lin, Kun-Yi/B-2503-2015; Kwon, Eilhann/AGY-3339-2022; Lee, Sang/ABC-8385-2020 | 56583023200; 57204070895; 57214885455; 44961317800; 57200873137; 55073290800; 55881252900; 57207957997; 7201888480; 9240622100 | youngjaejeon@pknu.ac.kr;ek2148@hanyang.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 466 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.54 | 2025-06-25 | 17 | 17 | Circular economy; Waste valorization; Biodegradable plastics; Polylactic acid; Carbon dioxide; Thermal treatment | GAS SHIFT REACTION; POLY(LACTIC ACID); POLYETHYLENE TEREPHTHALATE; THERMAL-STABILITY; PLASTIC WASTE; PLA; BIOMASS; BIODEGRADATION; CO2; VALORIZATION | Biodegradable plastics; Carbon dioxide; Circular economy; Polylactic acid; Thermal treatment; Waste valorization | Additives; Biodegradability; Biodegradable polymers; Carbon monoxide; Catalysts; Crosslinking; Elastomers; Energy resources; Fourier transform infrared spectroscopy; Plastics; Polyesters; Pyrolysis; Silica; Thermogravimetric analysis; Volatile organic compounds; Waste treatment; Biodegradable plastics; Circular economy; Condition; Homogeneous reaction; Lifespans; Polylactic acid; Syn gas; Thermochemicals; Waste generation rates; Waste valorizations; Carbon dioxide | English | 2023 | 2023-06-15 | 10.1016/j.cej.2023.143307 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
