| ○ | ○ | Article | Studies on corrosion monitoring of reinforced concrete in a chloride environment using an embedded solid-state reference electrode | In the present study, the corrosion status of steel rebars embedded in concrete with various cover thicknesses and exposed to conditions simulating a marine environment (3.5 % NaCl) was monitored by an embedded solid-state reference electrode (ESSRE). Electrochemical impedance spectroscopy (EIS) results confirm that corrosion initiation of the steel rebars occurred at 702, 1144, 1469 and 2454 h for C10, C15, C20 and C30 concrete specimens, respectively. Further, the relationship between the free and bound chlorides for C15, C20 and C30 specimens were defined by Temkin isotherm. In addition, the time to crack initiation was predicted by the El Maaddawy model. This study has successfully demonstrated that the solid-state MnO2 electrode is reliable for monitoring the onset of steel rebar corrosion in concrete by a non-destructive method. | Subbiah, Karthick; Lee, Han-Seung; Park, Taejoon; Annamalai, Sivasankar | Hanyang Univ, Dept Architectural Engn, 1271 Sa 3 dong, Ansan 15588, South Korea; Hanyang Univ, Dept Robot Engn, 55 Hanyangdaehak ro, Ansan 15588, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | Subbiah, Karthick/AAG-1014-2019; Annamalai, Sivasankar/G-7823-2016; Lee, Han-Seung/E-9087-2013 | 55949309800; 57956643400; 55717001200; 56388546200 | ercleehs@hanyang.ac.kr;taejoon@hanyang.ac.kr; | CONSTRUCTION AND BUILDING MATERIALS | CONSTR BUILD MATER | 0950-0618 | 1879-0526 | 364 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 7.4 | 3.0 | 0.9 | 2025-06-25 | 6 | 8 | Corrosion monitoring; Embeddable reference electrode; Chloride attack; Electrochemical method | SERVICE LIFE; STEEL; SENSOR; TIME; PERFORMANCE; MODEL; INTERFACE; BEHAVIOR; CRACKING; NIFE2O4 | Chloride attack; Corrosion monitoring; Electrochemical method; Embeddable reference electrode | Electrochemical corrosion; Electrochemical electrodes; Electrochemical impedance spectroscopy; Manganese oxide; Nondestructive examination; Sodium chloride; Steel corrosion; Chloride environment; Chlorides attacks; Corrosion-monitoring; Cover thickness; Electrochemical method; Embeddable reference electrode; Exposed to; Reference electrodes; Solid-state reference electrode; Steel rebars; Reinforced concrete | English | 2023 | 2023-01-18 | 10.1016/j.conbuildmat.2022.129964 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Adsorption and electrochemical regeneration of 2D magnetic MXene nanosheets loaded with tetracycline | A delaminated Ti3C2Tx MXene nanosheet-Fe3O4 nanoparticle composite (DLMX-Mag) was synthesized using a facile batch fabrication method and applied to an adsorption and electrochemical regeneration process for the removal of tetracycline (TC) from aqueous solutions. The addition of magnetite to the delaminated Ti3C2Tx MXene nanosheets produced a composite with magnetic properties, a larger surface area, and more functional groups attached to its surface. These characteristics are beneficial for magnetic solid-liquid separation and act to increase the adsorption capacity of the material. The experimental data of TC adsorption on DLMX-Mag were best described by the Elovich kinetic model, and the Freundlich isotherm model. Physical and chemical char-acterization revealed that the adsorption occurred via a surface complexation mechanism. Optimization of the electrochemical parameters resulted in 100% regeneration being achieved for DLMX-Mag. After the fifth cycle of electrochemical treatment, the physicochemical analysis results indicated that the crystallinity of the materials was slightly reduced; however, the addition of new functional groups had the effect of ensuring that the adsorptive capacity was retained. These findings demonstrate that the synthesized magnetic nano-adsorbents should be useful for industrial wastewater treatment. | Ghani, Ahsan Abdul; Kim, Bolam; Nawaz, Mohsin; Devarayapalli, Kamakshaiah C.; Lim, Youngsu; Kim, Gyuhyeon; Lee, Dae Sung | Univ Karachi, Dept Chem Engn, Main Univ Rd, Karachi 75270, Sindh, Pakistan; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Muhammad Nawaz Shareef Univ Agr, Dept Agr Engn, Old Shujabad Rd, Multan 66000, Pakistan | 57218294089; 57208922438; 55235830600; 15069351300; 57207112603; 58099353000; 55568524907 | daesung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 467 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 2.98 | 2025-06-25 | 32 | 32 | Magnetite; MXene; Tetracycline; Adsorption; Electrochemical regeneration | MOLECULARLY IMPRINTED POLYMER; HIERARCHICAL STRUCTURE; TI3C2 MXENE; WASTE-WATER; REMOVAL; ANTIBIOTICS; OXIDE; NANOPARTICLES; PERFORMANCE; COMPOSITE | Adsorption; Electrochemical regeneration; Magnetite; MXene; Tetracycline | Adsorption; Crystallinity; Industrial water treatment; Nanosheets; Synthesis (chemical); Wastewater treatment; Batch fabrication; Electrochemical regeneration; Fabrication method; Large surface area; Magnetic solids; Mxene; Regeneration process; Solid-liquid separation; Synthesised; Tetracycline; Magnetite | English | 2023 | 2023-07-01 | 10.1016/j.cej.2023.143473 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Adsorptive removal of carbazole from model esterified bio-oil composed of methyl laurate by using metal-organic frameworks functionalized with sulfonic acid both on metal and linker sites | Microalgae-derived esterified bio-oil can be an alternative energy source against the depletion of fossil fuel although the content of organonitrogen compounds (ONCs) can be high. Here, a metal-organic framework (MOF, MIL-101-NH2, with or without grafting ethylenediamine, ED) was modified to derive sulfonic acid-functionalized MIL-101 s. The obtained MOFs (including pristine MIL-101 and MIL-101-NH2), together with activated carbon (AC) as a reference, were utilized in adsorptive denitrogenation (ADN), especially the removal of carbazole (CBZ), one of the most difficult ONCs via hydrogenation or oxidation, from model fuel composed of methyl laurate. Although there was a study on ADN from model fuel composed of very light esters like methylacetate, there is no report using esters that are quite similar to fatty acid methyl esters of oils. Remarkably, MIL-101-NH-ED-SO3H, the first MOF having sulfonic acids on both the metal and linker sites, had noticeable maximum adsorption capacities (Qo) for the stubborn CBZ removal although the porosity is the lowest among the studied adsorbents. For example, Qo of the modified MOF was 205 mg/g which was higher than any studied adsorbents and was ca. 3 and 2 times that of AC and pristine MOF, respectively. The remarkable performance could be explained with H-bond (with a minor contribution of 7C-7C interaction), based on calculations, FTIR, and functional groups of both the adsorbate and adsorbent. Furthermore, the recyclability of MIL-101-NH-ED-SO3H in CBZ adsorption was confirmed. Therefore, MOFs when adequately functionalized can be useful in ADN of fuel composed of esters. | Hossain, Md.

| ○ | ○ | Article | Constructing peroxydisulfate selective N-doped carbon catalyst via copolymerization strategy for removal of organic contaminants | Nitrogen-doped carbon catalysts have shown high efficiency in activating both peroxydisulfate (PS) and peroxymonosulfate (PMS), making them well-suited for the removal of organic pollutants. In this study, we presented the fabrication of N-doped carbon by adopting copolymer strategy, where aniline and pyrrole are used as monomer molecules. As obtained catalyst displayed excellent bisphenol-A (BPA) removal efficiency with PS (similar to 98%) compared with PMS (60%). The effect of carbonization temperature on the chemical properties of copolymer-derived N-doped carbon (CNC) were studied using X-ray diffraction, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller analysis. Batch experiment results revealed that CNC is more catalytic to PS over PMS activation despite holding a decent amount of PMS active graphitic-N sites. This activity difference was attributed to unique graphitic-N configurations in the CNC. Electron spin resonance spectroscopy, scavenging experiments, and electrochemical studies combinedly revealed that no reactive oxygen species were generated in PS/CNC system. Instead, the BPA degradation proceeds via direct electron transfer mechanism. The optimized CNC system demonstrated promising activity for the removal of other frequently encountered phenolic compounds. Ultimately, this study challenges the generalized notion of high graphitic-N sites are always beneficial for high PMS activation capability, which is not applicable for N-doped carbon catalysts involving direct electron transfer process. | Silambarasan, Krishnamoorthy; Kumar, Alam Venugopal Narendra; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | 58045774500; 39262149400; 23019870800 | wshin@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 474 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.06 | 2025-06-25 | 12 | 11 | Nitrogen doped carbon; BPA; Water treatment; Persulfate activation; Conducting polymers | REDUCED GRAPHENE OXIDE; SINGLET OXYGEN; POROUS CARBON; NONRADICAL ACTIVATION; ENHANCED ACTIVATION; RATE CONSTANTS; BISPHENOL-A; NITROGEN; DEGRADATION; OXIDATION | BPA; Conducting polymers; Nitrogen doped carbon; Persulfate activation; Water treatment | Aniline; Carbonization; Catalysts; Chemical activation; Conducting polymers; Doping (additives); Efficiency; Electron spin resonance spectroscopy; Electron transitions; Magnetic moments; Organic pollutants; Phenols; X ray photoelectron spectroscopy; Bisphenol A; Bisphenols-A; Carbon catalysts; Doped carbons; N-doped; Nitrogen-doped carbons; Peroxydisulfate; Peroxymonosulfate; Peroxymonosulfate activations; Persulfate activations; Water treatment | English | 2023 | 2023-10-15 | 10.1016/j.cej.2023.145922 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Construction of novel In2S3/Ti3C2 MXene quantum dots/SmFeO3 Z-scheme heterojunctions for efficient photocatalytic removal of sulfamethoxazole and 4-chlorophenol: Degradation pathways and mechanism insights | In this study, we successfully designed a novel Ti3C2 MXene quantum dots (MQDs)-modified In2S3/MQDs/ SmFeO3 (IMS) Z-scheme heterojunction. We then investigated the crystal phases, chemical states, morphologies, and band structures of the Z-scheme catalysts in detail. The as-prepared IMS heterojunctions greatly facilitated the photocatalytic degradation of sulfamethoxazole (SMX) and 4-chlorophenol (4-CP) compared with the single and binary catalysts. The degradation of SMX under visible-light using the optimized IMS-3 ternary composite was clearly enhanced, and the degradation rates of 4-CP were 98.0 % and 95.4 % after 120 and 90 min of irradiation, respectively. The significantly enhanced photoactivity of the IMS composite was attributed to the effective spatial separation and charge transfer owing to the introduction of MQDs as charge-transport bridges in the Z-scheme system. Additionally, the unique properties of MQDs further accelerated the surface redox kinetics of the IMS catalyst, thus stimulating the formation of reactive species for pollutant degradation. Furthermore, these results indicate that MQDs not only act as electron mediators but also maintain the strong redox stability of IMS heterojunctions. This study offers a new avenue for developing efficient MQD-based Z-scheme photocatalysts and provides in-depth insights into the SMX degradation mechanism. | Saravanakumar, Karunamoorthy; Yun, Keunyoung; Maheskumar, Velusamy; Yea, Yeonji; Jagan, Govindan; Park, Chang Min | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; Park, Chang Min/CAA-8506-2022; Karunamoorthy, Saravanakumar/Q-2005-2016 | 57223020778; 57884548300; 57004930400; 57217304205; 57885044400; 57209588953 | cmpark@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 451 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 10.58 | 2025-06-25 | 103 | 111 | MQDs; SmFeO3; MXene quantum dots; Z-scheme; Photocatalyst; Degradation | VISIBLE-LIGHT; PHOTODEGRADATION; NANOCOMPOSITE; FABRICATION; NANOSHEETS; IN2S3 | Degradation; In<sub>2</sub>S<sub>3</sub>/MQDs/SmFeO<sub>3</sub>; MXene quantum dots; Photocatalyst; Z-scheme | Catalysts; Charge transfer; Heterojunctions; Indium compounds; Nanocrystals; Semiconductor quantum dots; Titanium compounds; 4-chlorophenols; Crystal phasis; Degradation mechanism; Degradation pathways; In2S3/mxene quantum dot/SmFeO3; Mxene quantum dot; Photo-catalytic removal; Sulfamethoxazole; Z-scheme; ]+ catalyst; Degradation | English | 2023 | 2023-01-01 | 10.1016/j.cej.2022.138933 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Conversion of toxic chemicals into flammable gases through the thermolysis of polyurethane foam using CO2 | Construction waste is considered an environmental problem because its landfilling/incineration treatment methods has noticeably increased the likelihood of releasing microplastics, leachates, air pollutants, and toxic gases into the environment. Nevertheless, an environmentally benign disposal protocol for building plastic waste has yet to be fully implemented. In this study, a cleaner and safer disposal platform for building plastic waste is suggested. Specifically, the thermo-chemical treatment of building insulator waste (BIW) was conducted using CO2 as a key detoxifying agent. The BIW used in this study was composed of polyurethane foam (PUF), according to instrumental analyses. The thermal degradation of the PUF resulted in the dominant production of hazardous chemicals such as 4,4 '-methylenedianiline (MDA) and its derivatives. The toxic compounds were transformed/ detoxified into syngas (H2/CO) through the catalytic pyrolysis of PUF over nickel-based catalysts. Using CO2 as a detoxifying agent, MDA and its derivatives were further transformed into CO due to the homogeneous chemical reaction between CO2 and toxic compounds. 78.4 wt% of toxic compounds were converted into syngas over the CO2-mediated catalytic pyrolysis. Simultaneous reduction of toxic chemicals and production of value-added compounds propose that CO2 has a great potential to be used as a reaction medium to suppress toxic chemi-cal valorization. Thus, this study experimentally confirmed the technical viability of catalytic pyrolysis under CO2 as a promising disposal platform for BIW, effectively suppressing the fate of toxic compounds. | Lee, Taewoo; Kim, Jung-Hun; Tsang, Yiu Fai; Chen, Wei-Hsin; Lee, Doyeon; Jung, Min-Woong; Jung, Sungyup; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, Peoples R China; 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; Hanbat Natl Univ, Dept Civil & Environm Engn, Daejeon 34158, South Korea; Natl Inst Anim Sci NIAS, Dept Anim Environm, Wonju 55365, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | ; Chen, Wei-Hsin/S-2033-2018; Jung, Sungyup/ABE-1493-2021; LEE, TAEWOO/MXK-6996-2025; Tsang, Yiu/AAJ-2524-2020; Kwon, Eilhann/AGY-3339-2022 | 57194348573; 57204508711; 22954605700; 57200873137; 55881252900; 55890039300; 55073290800; 9240622100 | sjung001@kmu.ac.kr;sjung001@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 457 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 0.58 | 2025-06-25 | 6 | 6 | Circular economy; Waste-to-energyCO2 utilization; Polyurethane foam; Thermo-chemical disposal | PYROLYSIS; SYNGAS; FUEL | Circular economy; Polyurethane foam; Thermo-chemical disposal; Waste-to-energy, CO<sub>2</sub> utilization | Degradation; Indicators (chemical); Polyurethanes; Rigid foamed plastics; Waste disposal; Waste treatment; Catalytic pyrolysis; Chemical disposal; Circular economy; Polyurethane Foam; Thermo-chemical; Thermo-chemical disposal; Toxic chemicals; Toxic compounds; Waste to energy; Waste-to-energy, CO2 utilization; Carbon dioxide | English | 2023 | 2023-02-01 | 10.1016/j.cej.2023.141291 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Development of a method for analysis and risk assessment of residual pesticides in ginseng using liquid and gas chromatography-tandem mass spectrometry | In this study, we developed a method for detecting 335 pesticides in ginseng using liquid chromatography quadrupole mass spectrometry (LC-MS/MS) and gas chromatography quadrupole mass spectrometry (GC-MS/ MS). Additionally, the linearity, sensitivity, selectivity, accuracy, and precision of the method was validated. The limits of detection (LOD) and limits of quantification (LOQ) for the instrument used in these experiments was 0.1-5.8 & mu;g/kg and 0.3-17.5 & mu;g/kg, respectively. The average recovery was 71.6-113.4%. From 2016 to 2019, 467 ginseng samples were analyzed, of which 304 samples detected pesticide residues, but most of them were below the standard. It can be observed that the hazard quotient (HQ) of ginseng for detected pesticides was less than 1, thus implying that the risk was low. Hence, in this study, we developed a specific, reliable, and suitable method for a fast and simultaneous analysis of 335 pesticides in ginseng. | Kim, Hyoyoung; Baek, Eun Joo; Kim, Yong-Kyoung; Park, Hyejin; Hur, Suel Hye; Kim, Jang-Eok; Kim, Ho Jin | Natl Agr Prod Qual Management Serv, Expt Res Inst, 141 Yongjeon Ro, Gimcheon 39660, Gyeongsangbuk, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Sch Appl Biosci, Major Environm & Life Chem, Daegu 41566, South Korea | ; Kim, Seung/N-5248-2019; Kim, Young Hoon/F-5424-2012 | 57224535109; 58403858000; 57918934100; 57220081793; 58242339300; 7601387161; 56372903900 | jekim@knu.ac.kr;rex7878@korea.kr; | FOOD CHEMISTRY | FOOD CHEM | 0308-8146 | 1873-7072 | 427 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY;NUTRITION & DIETETICS | 2023 | 8.5 | 3.1 | 1.23 | 2025-06-25 | 10 | 10 | Pesticides; Simultaneous analysis; Liquid chromatography-mass spectrometry; Gas chromatography-mass; Food safety; Ginseng | COMPONENTS; ROOT | Food safety; Gas chromatography-mass; Ginseng; Liquid chromatography-mass spectrometry; Pesticides; Simultaneous analysis | Chromatography, Liquid; Gas Chromatography-Mass Spectrometry; Panax; Pesticide Residues; Pesticides; Risk Assessment; Tandem Mass Spectrometry; Chemical contamination; Food safety; Liquid chromatography; Mass spectrometry; Pesticides; Risk analysis; Risk assessment; pesticide; pesticide residue; pesticide; pesticide residue; Food-safety; Gas chromatography-mass; Gas chromatography-quadrupole mass spectrometry; Gas chromatography/tandem mass spectrometries; Ginseng; LC-MS-MS; Liquid chromatography - mass spectrometries; Quadrupole mass spectrometry; Risks assessments; Simultaneous analysis; Article; chromatography; electrospray; estimated daily intake; food safety; gas chromatography; gas flow; ginseng; limit of detection; limit of quantitation; liquid chromatography; liquid chromatography-mass spectrometry; mass fragmentography; matrix effect; nonhuman; quadrupole mass spectrometry; quantitative analysis; retention time; risk assessment; sequence analysis; short term exposure; tandem mass spectrometry; chemistry; Panax; procedures; risk assessment; tandem mass spectrometry; Gas chromatography | English | 2023 | 2023-11-30 | 10.1016/j.foodchem.2023.136675 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of a pH indicator for monitoring the freshness of minced pork using a cellulose nanofiber | A cellulose nanofiber (CNF)-based pH-sensitive indicator was developed by mixing CNF with red radish color extract (RRCE) to analyze the freshness of minced pork. Among various mixing conditions of RRCE solutions (0.4-1.6%) and CNF (0.5-1.25%), 0.8% RRCE/1% CNF showing higher mechanical properties, lower response to water, lower leakage of RRCE, and higher sensitivity to ammonia was selected as optimum. Ultraviolet-visible light transmittance and structural properties of the film indicated successful incorporation of RRCE into CNF, with rapid response to changes in pH caused by ammonia solution. The water vapor permeability of the indicator was maintained for 48 h. The fabricated pH-sensitive indicator showed apparent color changes from red color (fresh) to purple color (spoiled) during pork storage at refrigeration temperature.

The change value (CV) of Warner--Bratzler shear force (WBS) was determined as the difference in WBS between 0 and 14 d of aging. The higher change (HC) value group exhibited lower WBS and higher initial tenderness values than the lower change (LC) value group aged 14 and 28 d (P 0.05). The higher tenderness improvement in the HC group at 14 d might be related to the lower cy-tochrome C and caspase values and higher degradation of desmin and troponin T compared to the LC group (P < 0.05). | Kim, Jae Yeong; Lee, Boin; Kim, Eun Joong; Choi, Young Min | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju Si 37224, South Korea | Kim, Eun Joong/HGF-1639-2022 | 57226306561; 57218130871; 57213620881; 57226673843 | ymchoi1@knu.ac.kr; | FOOD CHEMISTRY | FOOD CHEM | 0308-8146 | 1873-7072 | 248 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY;NUTRITION & DIETETICS | 2023 | 8.5 | 3.1 | 0.37 | 2025-06-25 | 2 | 3 | Postmortem aging; Sensory quality; Tenderness variation; Caspase system; Holstein | MARBLING FLECK CHARACTERISTICS; SKELETAL-MUSCLE; SENSORY QUALITY; CYTOCHROME-C; MEAT; TENDERIZATION; TENDERNESS; CHICKEN; HANWOO; PROTEOLYSIS | Caspase system; Holstein; Postmortem aging; Sensory quality; Tenderness variation | Animals; Autopsy; Caspases; Cattle; Meat; Muscle, Skeletal; Proteolysis; Shear flow; caspase; cytochrome c; desmin (protein); muscle protein; troponin T; Apoptotic factors; Caspase system; Caspases; Holstein; Longissimus; Postmortem aging; Sensory qualities; Shear force; Tenderness variation; Value group; aging; animal tissue; apoptosis; Article; bullock; comparative study; Holstein-Friesian cattle; longissimus thoracis; meat; nonhuman; palatability; protein degradation; shear strength; animal; autopsy; bovine; meat; metabolism; skeletal muscle; Muscle | English | 2023 | 2023-12-01 | 10.1016/j.foodchem.2023.136741 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficient adsorption of naproxen and ibuprofen by gelatin/zirconium-based metal-organic framework/sepiolite aerogels via synergistic mechanisms | The removal of non-steroidal anti-inflammatory drugs (NSAIDs) from effluent wastewater is critical because of their adverse impacts on human health and the ecosystem. In this study, we successfully fabricated a novel biopolymer-based aerogel composite by incorporating a zirconium-based metal-organic framework, UiO-66 (MOF), and sepiolite (Sep) into gelatin (Gel) to efficiently remove naproxen (NPX) and ibuprofen (IBP). The physicochemical properties of the prepared adsorbents were comprehensively characterized, as well as batch experimental studies were carried out to probe the effect of contact time, solution pH, temperature, and coex-isting ions on the adsorption process. The adsorption by the 3D mesoporous aerogel (Gel-1.0MOF-Sep) followed the pseudo-second order and the Langmuir isotherm models with maximum adsorption capacities of 8.515 and 10.23 mg/g for NPX and IBP, respectively (at 20 degrees C and pH 7). Furthermore, central composite design (CCD) in response surface methodology (RSM) was used to assess the simultaneous interactions of independent variables, results of which suggested that the initial concentration and pH were the dominant parameters in the adsorption process. Moreover, a thermodynamic study showed that the adsorption process was exothermic (Delta H degrees < 0). Reusability studies demonstrated that the composite aerogel exhibited superior adsorption efficiencies after five successive runs, indicating its potential use in practical ap-plications. Furthermore, the adsorption mechanisms for the pollutants were ascribed to electrostatic interactions, 7C-7C interactions, and hydrogen bonding. The insights show that the Gel-1.0MOF-Sep aerogels are promising alternative adsorbents for the removal of NSAIDs. | Njaramba, Lewis Kamande; Kim, Minseok; Yea, Yeonji; Yoon, Yeomin; Park, Chang Min | 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; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae gil, Seoul 03760, South Korea | Kamande, Lewis/JLL-5435-2023; Yoon, Yeomin/KDP-2253-2024; Park, Chang Min/CAA-8506-2022 | 57223183206; 59073001500; 57217304205; 7402126688; 57209588953 | yoony@cec.sc.edu;cmpark@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 452 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 6.25 | 2025-06-25 | 65 | 66 | Naproxen; Ibuprofen; Adsorption; Gelatin; UiO-66 MOF; Sepiolite | AQUEOUS-SOLUTIONS; FACILE SYNTHESIS; REMOVAL; WATER; FRAMEWORKS; ADSORBENT; EQUILIBRIUM; DEGRADATION; ISOTHERM; UIO-66 | Adsorption; Gelatin; Ibuprofen; Naproxen; Sepiolite; UiO-66 MOF | Aerogels; Biopolymers; Effluents; Hydrogen bonds; Isotherms; Physicochemical properties; Reusability; Adsorption process; Gelatin; Human health; Ibuprofen; Metalorganic frameworks (MOFs); Naproxens; Non-steroidal anti-inflammatory drugs; Sepiolite; Synergistic mechanism; UiO-66 metal–organic framework, UiO-66; Adsorption | English | 2023 | 2023-01-15 | 10.1016/j.cej.2022.139426 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficient metal-free aerobic oxidative desulfurization with nitrogen and sulfur co-doped covalent organic polymer-derived carbon | A nitrogen and sulfur co-doped carbon was prepared from a covalent-organic polymer named microporous triazine polymer (MCTP) for the first time by loading NH4NO3 and diphenyldisulfide followed by pyrolysis. The obtained carbons (named NSMDCs) were exploited as environment-friendly metal-free catalysts for oxidative desulfurization of organo sulfurous compounds (OSCs) from a dodecane-based simulated fuel using molecular oxygen (O2) as an oxidizing agent. One of the materials showed a nearly complete conversion of an OSC, dibenzothiophene, after a reaction of 4 h at 100 degrees C which is one of the lowest temperatures among the metal-free ODS catalyses. A very low activation energy (Ea) of 30.4 kJmol-1 was found for the DBT oxidation which is also lower than or competitive against most of other reported results (including the ones using metal-based catalysts). Radical scavenging investigations and ESR analyses showed the generation of superoxide anion radicals (O2-& BULL;) from O2 that might have a dominant role in the oxidation or ODS. Moreover, DFT calculation revealed the generation of increased charge difference on the surface of the N and S co-doped catalyst. A plausible reaction mechanism including the effective activation of O2 was proposed. The catalyst was effectively used for at least five runs without noticeable degradation with simple acetone soaking and further washing. | Ahmed, Imteaz; Kim, Chul-Ung; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Korea Res Inst Chem Technol KRICT, Chem & Proc Technol Div, POB 107, 141 Gajeong Ro, Yuseong 34114, Daejeon, South Korea | Jhung, Sung/AAO-6683-2021 | 55377179600; 9742142700; 6701659467 | imteaz2004@gmail.com;sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 474 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.25 | 2025-06-25 | 15 | 14 | Aerobic oxidation; Desulfurization; Metal -free catalyst; Nitrogen and sulfur co-doping; Oxidation mechanism | OXYGEN REDUCTION; CATALYTIC-OXIDATION; IONIC LIQUID; DIESEL FUEL; GRAPHENE; ADSORPTION; OILS; BIODESULFURIZATION; DENITROGENATION; NANOSPHERES | Aerobic oxidation; Desulfurization; Metal-free catalyst; Nitrogen and sulfur co-doping; Oxidation mechanism | Acetone; Activation energy; Carbon; Catalysts; Desulfurization; Molecular oxygen; Nitrogen; Organic polymers; Oxidation; Aerobic oxidations; Co-doped; Co-doping; Desulphurization; Metal free; Metal-free catalysts; Nitrogen and sulphur co-doping; Oxidation mechanisms; Oxidative desulfurization; Sulphurous compounds; Sulfur | English | 2023 | 2023-10-15 | 10.1016/j.cej.2023.145652 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Engineered mesoporous hollow carbon spheres for pollutant degradation: Disclosing catalytic activity, matrix effect, transport, and aquatic ecotoxicity | Remediation of organic contaminants through advanced oxidation process hold great promise for both ground and surface water environments. Despite the fact, the treatment efficiency depends on multiple factors, i.e., catalyst dosage, persulfate/peroxymonosulfate activation capability, and catalyst toxicity to aquatic creatures. Herein, we aimed to demonstrate the potential of the mesoporous carbon hollow sphere (MCHS) catalyst in persulfate activation for advanced oxidation in pure and groundwater matrix by choosing tetracycline as a model compound. Surface properties of MCHS were examined using multiple characterization techniques and the data revealed that MCHS is benefited by high specific surface area, numerous mesopores, and an excellent degree of particle dispersion. The results of this study indicate that pH, catalyst dosage, and persulfate and tetracycline concentrations influence tetracycline's degradation rate. Features like colloidal nature, high specific surface area (>1200 m2/g), and porosity of MCHS allow for very low catalyst dosage (10 mg L-1). Electron spin resonance (ESR) and scavenger studies showed that the TC degradation in persulfate/MCHS system is dominated by 1O2 rather than center dot OH, and SO4 center dot- radical species. Electrochemical study confirmed that electrons are transferred from tetracycline to the persulfate/MCHS complex during oxidation reaction. Additionally, the tetracycline degra-dation performance in natural groundwater matrices outperforms the persulfate/MCHS pure water system. Ecotoxicity study revealed the survival rate of Daphnia magna neonates is >95% if MCHS is <12 mg L-1. | Kumar, Alam Venugopal Narendra; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | 39262149400; 23019870800 | wshin@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 454 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.73 | 2025-06-25 | 19 | 19 | Carbon catalyst; Groundwater treatment; Mesoporous hollow -carbon spheres; Persulfate activation; Tetracycline | PEROXYMONOSULFATE ACTIVATION; ENVIRONMENTAL REMEDIATION; PERSULFATE; OXIDATION; WATER; IRON; NANOPARTICLES; ADSORPTION; NANOTUBES; METHANOL | Carbon catalyst; Groundwater treatment; Mesoporous hollow-carbon spheres; Persulfate activation; Tetracycline | Catalyst activity; Chemical activation; Electron spin resonance spectroscopy; Groundwater; Magnetic moments; Mesoporous materials; Oxidation; Specific surface area; Spheres; Surface waters; Water treatment; Carbon catalysts; Carbon hollow-spheres; Groundwater treatment; Hollow carbon spheres; Mesoporous; Mesoporous carbon; Mesoporous hollow-carbon sphere; Persulfate activations; Tetracycline; ]+ catalyst; Degradation | English | 2023 | 2023-02-15 | 10.1016/j.cej.2022.140475 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Enhancement of peroxydisulfate activation by inherent nature of Fe-N-P/C biochar derived from Capsosiphon fulvescens as a green biomass material for organic pollutants degradation | This study explores the catalytic activity of biochar materials derived from seaweed biomass (Capsosiphon fulvescens) for groundwater treatment. A facile pyrolysis process was utilized to prepare C. fulvescens biochar (CFBCX), where X represents the pyrolysis temperature. The instrumental analysis using surface characterization techniques revealed that CFBC800 inherently contained heteroatoms (N, P) and a trace metal (Fe) in the biochar. The adsorption kinetics and isotherm experiments depicted a mixed mechanism of physical and chemical adsorption of SDZ on CFBC. Consequently, in optimal conditions with 2 mM peroxydisulfate (PDS), 200 mg L-1 CFBC800, and 6.1 initial solution pH, SDZ degradation (>97.2%) is achieved within 60 min. Chemical quenching tests indicate the involvement of radical (O-2(center dot-) = 41.6%) and non-radical processes, including electron transfer (58.4%), in the PDS/CFBC800 system. The electron spin resonance spectroscopy confirmed the formation of reactive oxygen species (ROS) in the PDS/CFBC800 system, including radical (O-2(center dot-), SO4 center dot-, and HO center dot) and non-radical (O-1(2)) species. Furthermore, electrochemical studies demonstrated the existence of an electron transfer pathway in the non-radical process of the PDS/CFBC800 system. Based on chemical scavenger and ESR analyses, the PDS/CFBC800 system exhibited both radical and non-radical mechanisms, with the electron transfer pathway being more dominant in this catalytic system. The excellent catalytic activity of the PDS/CFBC800 system toward co-existing ions and various organic contaminant degradation is demonstrated. Moreover, the CFBC800-activated PDS system successfully demonstrated catalyst reusability in SDZ degradation. Thus, this study establishes CFBC800 as an ecofriendly catalyst with remarkable catalytic activity for groundwater remediation. | Seo, Giung; Annamalai, Sivasankar; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Saveetha Inst Med & Tech Sci, Saveetha Med Coll & Hosp, Ctr Global Hlth Res, Chennai 600077, India | Annamalai, Sivasankar/G-7823-2016 | 58632804300; 56388546200; 23019870800 | wshin@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 475 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2023 | 13.4 | 3.1 | 1.83 | 2025-06-25 | 19 | 19 | Sulfadiazine; Seaweed biomass; Biochar; Peroxydisulfate; Superoxide; Electron transfer pathway | DOPED GRAPHENE; CARBON; REMOVAL; IRON; ANTIBIOTICS; NITROGEN; OXIDATION; BORON; NANOPARTICLES; CONTAMINANTS | Biochar; Electron transfer pathway; Peroxydisulfate; Seaweed biomass; Sulfadiazine; Superoxide | Aromatic compounds; Catalyst activity; Electron spin resonance spectroscopy; Electron transitions; Free radical reactions; Groundwater; Magnetic moments; Organic pollutants; Reusability; Seaweed; Trace elements; Water treatment; Biochar; Biomass materials; Electron transfer pathways; Groundwater treatment; Organic pollutant degradation; Peroxydisulfate; Radical process; Seaweed biomass; Sulfadiazine; Superoxides; Biomass | English | 2023 | 2023-11-01 | 10.1016/j.cej.2023.146445 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
