| ○ | ○ | Article | Flexible nanoporous activated carbon cloth for achieving high H2, CH4, and CO2 storage capacities and selective CO2/CH4 separation | Innovative tools are needed for the synthesis of smart, new, efficient, and safe nanoporous carbon materials for energy gas storage. Here, a flexible nanoporous activated carbon cloth was developed. Polypyrrole nanoparticles were polymerized in dispersed form on commercial viscose rayon cloth fiber surfaces. Then, the material was carbonized and activated by physical and chemical activation methods applied individually. Chemical activation conditions were varied and optimized. This produced a high porosity flexible nanoporous carbon textile with a surface area of similar to 2000 m(2) g(-1), total pore volume of 0.85 cm(3) g(-1), and high nitrogen content. The new flexible nanoporous carbon cloth achieved superior H-2 and CH4 storage capacities and CO2 capture compared to so-farreported activated carbon cloth, and values were comparable to or higher than those reported for powder activated carbons. Excess H-2 uptake values were 4.0 and 0.173 wt% at 77 K and 298 K at 20 bar, respectively, and CH4 storage amounted to 7.5 mmol g(-1) at 20 bar and 298 K, which is among the highest reported values for porous carbon materials. CO2 uptake values were 4.2 and 14.3 mmol g(-1) at 1 and 20 bar at 298 K, respectively, which are values superior to those previously reported for activated carbon cloth. Hence, the flexible nanoporous activated carbon cloth is effective for greenhouse gas (i.e., CO2) uptake during post- and pre-combustion conditions. Separation selectivity for CO2/CH4 binary mixtures was evaluated based on the ideal adsorbed solution theory (IAST) model and a high value of 15.9 was achieved. | Attia, Nour F.; Jung, Minji; Park, Jaewoo; Jang, Haenam; Lee, Kiyoung; Oh, Hyunchul | Gyeongnam Natl Univ Sci & Technol GNTECH, Dept Energy Engn, Jinju 52725, South Korea; Natl Inst Stand, Chem Div, Fire Protect Lab, Giza 12211, Egypt; Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, Sangju 37224, Gyeongbuk, South Korea; Future Convergence Technol Res Inst, Jinju 52725, South Korea | ; Attia, Nour/Y-6090-2019; Oh, Hyunchul/G-5697-2018; Lee, Kiyoung/J-8680-2013 | 55626177100; 57202773720; 59879025300; 57203155764; 57219211501; 55340650900 | oh@gntech.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 379 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 4.57 | 2025-06-25 | 121 | 128 | Activated carbon materials; Flexible nanoporous carbon cloth; H-2 and CH4 storage; Greenhouse gas; CO2/CH4 selectivity | METAL-ORGANIC FRAMEWORKS; HIGH-SURFACE-AREA; HYDROGEN-STORAGE; METHANE STORAGE; POROUS CARBONS; PORE STRUCTURE; VISCOUS RAYON; ADSORPTION; GAS; CAPTURE | Activated carbon materials; CO<sub>2</sub>/CH<sub>4</sub> selectivity; Flexible nanoporous carbon cloth; Greenhouse gas; H<sub>2</sub> and CH<sub>4</sub> storage | Activated carbon; Binary mixtures; Carbon dioxide; Chemical activation; Clothes; Greenhouse gases; Polypyrroles; Porous materials; Precombustion; Rayon; Activated carbon cloth; High nitrogen content; Ideal adsorbed solution theories (IAST); Nanoporous activated carbons; Nanoporous carbons; Porous carbon materials; Powder activated carbon; Separation selectivity; Storage (materials) | English | 2020 | 2020-01-01 | 10.1016/j.cej.2019.122367 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Highly robust and efficient Ti-based Sb-SnO2 anode with a mixed carbon and nitrogen interlayer for electrochemical 1,4-dioxane removal from water | Ti-based Sb-SnO2 electrodes are attractive due to their excellent catalytic activity but have a short service life. Here, we report a highly stable and efficient Ti/TiONC/Sb-SnO2 electrode, which was fabricated through hydrothermal reactions using urea to form TiONC interlayers and electrodeposition-annealing to coat the active SbSnO2 catalysts. The triple-layered anode was characterized by highly crystalline structures, high oxygen evolution potentials, and corrosion-resistance properties. The structural arrangement yielded better electrocatalytic performances than that using the control electrode (Ti/Sb-SnO2), showing enhanced organics degradation efficiencies. This new electrode's lifetime was significantly (similar to 25 times) longer than that of either the control or any Sb-SnO2 electrode modified with non-precious materials reported in the literature. The electrode's enhanced stability was attributed to the insertion of the mixed C and N interlayers that are resistant to oxidants and corrosive ions. The Ti/TiONC/Sb-SnO2 anode holds promise for use in electrochemical water treatment. | Mameda, Naresh; Park, Hyeona; Shah, Syed Salman Ali; Lee, Kibaek; Li, Chi-Wang; Naddeo, Vincenzo; Choo, Kwang-Ho | Kyungpook Natl Univ, Adv Inst Water Ind, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Chonnam Natl Univ, Dept Biotechnol & Biochem Engn, 77 Yongbong Ro, Gwangju 61186, South Korea; Tamkang Univ, Dept Water Resources & Environm Engn, 151 Yingzhuan Rd, New Taipei 25137, Taiwan; Univ Salerno, Dept Civil Engn, Sanit Environm Engn Div, I-84084 Fisciano, SA, Italy | ; Mameda, Naresh/AAV-2711-2020; Shah, Syed Salman Ali/JCE-1663-2023; Li, Chi-Wang/G-1254-2015; Mameda, Dr. Naresh/AAV-2711-2020; Choo, Kwang-Ho/A-3456-2016; Naddeo, Vincenzo/C-4057-2008 | 57192214360; 57213039681; 57215722996; 55845961700; 56621869300; 57225215311; 7102083272 | chookh@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 393 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 1.95 | 2025-06-25 | 67 | 66 | Sb-SnO2; Electrode stability; Interlayer; Service life; 1,4-Dioxane | DOPED SNO2 ELECTRODE; WASTE-WATER; TI/SNO2-SB ELECTRODES; ELECTROCATALYTIC ACTIVITIES; HYDROTHERMAL SYNTHESIS; TI/SB-SNO2 ELECTRODE; ORGANIC POLLUTANTS; METHYLENE-BLUE; OXIDATION; DEGRADATION | 1,4-Dioxane; Electrode stability; Interlayer; Sb-SnO<sub>2</sub>; Service life | Anodes; Antimony compounds; Carbon; Catalyst activity; Corrosion resistance; Degradation; Nanocrystalline materials; Nitrogen; Nitrogen removal; Service life; Urea; Water treatment; 1 ,4-Dioxane; Crystalline structure; Degradation efficiency; Electrocatalytic performance; Electrode stability; Hydrothermal reaction; Interlayer; Structural arrangement; Titanium compounds | English | 2020 | 2020-08-01 | 10.1016/j.cej.2020.124794 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Histone sumoylation promotes Set3 histone-deacetylase complex-mediated transcriptional regulation | Histones are substrates of the SUMO (small ubiquitin-like modifier) conjugation pathway. Several reports suggest histone sumoylation affects transcription negatively, but paradoxically, our genome-wide analysis shows the modification concentrated at many active genes. We find that trans-tail regulation of histone-H2B ubiquitylation and H3K4 dimethylation potentiates subsequent histone sumoylation. Consistent with the known control of the Set3 histone deacetylase complex (HDAC) by H3K4 dimethylation, histone sumoylation directly recruits the Set3 complex to both protein-coding and noncoding RNA (ncRNA) genes via a SUMO-interacting motif in the HDAC Cprl subunit. The altered gene expression profile caused by reducing histone sumoylation matches well to the profile in cells lacking Set3. Histone H2B sumoylation and the Set3 HDAC coordinately suppress cryptic ncRNA transcription initiation internal to mRNA genes. Our results reveal an elaborate co-transcriptional histone crosstalk pathway involving the consecutive ubiquitylation, methylation, sumoylation and deacetylation of histones, which maintains transcriptional fidelity by suppressing spurious transcription. | Ryu, Hong-Yeoul; Zhao, Dejian; Li, Jianhui; Su, Dan; Hochstrasser, Mark | Kyungpook Natl Univ, Coll Natl Sci, BK21 Plus KNU Creat BioRes Grp, Sch Life Sci, Daegu 41566, South Korea; Yale Univ, Yale Ctr Genome Anal, New Haven, CT 06520 USA; Yale Univ, Dept Mol Biophys & Biochem, New Haven, CT 06520 USA | ; su, dan/GYJ-1940-2022; Zhao, Dejian/C-8321-2009 | 55889917800; 56145853100; 57212139387; 59096523200; 26643419800 | rhr4757@knu.ac.kr;mark.hochstrasser@yale.edu; | NUCLEIC ACIDS RESEARCH | NUCLEIC ACIDS RES | 0305-1048 | 1362-4962 | 48 | 21 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY | 2020 | 16.971 | 2.5 | 1.71 | 2025-06-25 | 39 | 37 | SACCHAROMYCES-CEREVISIAE; H2B UBIQUITYLATION; SYSTEMATIC IDENTIFICATION; PERVASIVE TRANSCRIPTION; BIDIRECTIONAL PROMOTERS; SUMO; PROTEIN; METHYLATION; H3K4; RNA | Acetylation; Cyclophilin A; Gene Expression Regulation, Fungal; Histone Deacetylases; Histones; Methylation; Protein Processing, Post-Translational; RNA; RNA, Untranslated; Saccharomyces cerevisiae; Saccharomyces cerevisiae Proteins; Sumoylation; Transcription, Genetic; Ubiquitin; Ubiquitination; histone; histone deacetylase; histone H2B; histone H3; histone H3 lysine 4; lysine; messenger RNA; protein Set3; SUMO protein; unclassified drug; untranslated RNA; CPR1 protein, S cerevisiae; cyclophilin A; histone; histone deacetylase; histone H3 trimethyl Lys4; RNA; Saccharomyces cerevisiae protein; Set3 protein, S cerevisiae; ubiquitin; untranslated RNA; Article; controlled study; deacetylation; gene; histone acetylation; histone methylation; nonhuman; priority journal; protein expression; protein motif; sumoylation; transcription initiation; transcription regulation; ubiquitination; acetylation; gene expression regulation; genetic transcription; genetics; metabolism; methylation; protein processing; Saccharomyces cerevisiae; sumoylation | English | 2020 | 2020-12-02 | 10.1093/nar/gkaa1093 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Metal-organic framework MIL-101 loaded with polymethacrylamide with or without further reduction: Effective and selective CO2 adsorption with amino or amide functionality | In order to improve the performances of a typical/highly porous metal-organic framework (MOF, MIL-101 structure) in CO2 adsorption/capture, methacrylamide was polymerized (to polymethacrylamide or PM) inside of MIL-101 (to get PM@MOF) and further reduced with lithium aluminum hydride. The obtained adsorbents (R-PM24@MOF or PM24@MOF) had highly enhanced performances, compared with the pristine MOF, in CO2 capture both in the adsorption capacity (especially at low pressure of 0.15 atm) and adsorption selectivity (against N-2), suggesting the polyamides loading (and subsequent reduction) on MOFs is an effective mean to derive competitive adsorbent for CO 2 adsorption/capture. For example, the developed adsorbent (R-PM24@ MOF) showed 1.4 mmol/g of adsorbed CO2 (at 0.15 atm and 298 K) and adsorption selectivity (CO2/N-2) of 143 at 298 K (CO2/N-2 = 0.75/0.15, at 1 atm); which are similar to 3 and similar to 10 times to that of pristine MIL-101, respectively. The remarkably enhanced performances could be explained with the introduced functional groups and reduced porosity (for decreased N-2 adsorption). Moreover, the adsorbent could be easily recycled, suggesting the potential application in selective adsorption of CO2 from off gas of post-combustions. | Yoo, Dong Kyu; Yoon, Tae-Ung; Bae, Youn-Sang; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, 50 Yonsei Ro, Seoul 03722, South Korea | Jhung, Sung/AAO-6683-2021 | 57201339246; 56622173900; 7201465967; 6701659467 | mowbae@yonsei.ac.kr;sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 380 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 4.07 | 2025-06-25 | 75 | 83 | Adsorption; CO2; Metal organic frameworks; MIL-101; Polyamides | CARBON-DIOXIDE CAPTURE; MIXED MATRIX MEMBRANES; CO2/CH4 SELECTIVITY; FLUE-GAS; SEPARATION; SORPTION; CAPACITY; POLYMER; ZIF-8; AIR | Adsorption; CO<sub>2</sub>; Metal organic frameworks; MIL-101; Polyamides | Adsorption; Aluminum compounds; Amides; Crystalline materials; Gas adsorption; Lithium compounds; Organometallics; Polyamides; Adsorption capacities; Adsorption selectivity; Amide functionalities; Lithium aluminum hydride; Metal organic framework; MIL-101; Selective adsorption; Subsequent reduction; Carbon dioxide | English | 2020 | 2020-01-15 | 10.1016/j.cej.2019.122496 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Photo-Fenton reaction for the degradation of sulfamethoxazole using a multi-walled carbon nanotube-NiFe2O4 composite | In this study, magnetically recyclable spinel nickel ferrite (NiFe2O4) and multi-walled carbon nanotubes (MWCNTs) incorporated NiFe2O4 (NiFe-CNT) composite with different CNT contents were successfully synthesized by one-step hydrothermal treatment. The photo-Fenton efficiency of the synthesized materials was assessed by the degradation of recalcitrant sulfamethoxazole (SMX) under ultraviolet (UV)-A and visible light. The efficiency of poorly active NiFe2O4 was significantly enhanced by the incorporation of 25 wt% CNT, and complete degradation of SMX (5 mg/L) was achieved within 2 h using NiFe-CNT composite (0.025 g/L) in the presence of H2O2 under UV-A light. Higher mineralization (total organic carbon (TOC) removal = 68%) was obtained in case of NiFe-CNT composite than bare NiFe2O4 (TOC removal = 39%). The effects of catalyst dosage, SMX concentration, H2O2 concentration, and pH on the degradation of SMX were investigated in order to identify the optimized reaction conditions. No leaching or degradation of MWCNTs was observed in the reaction solution and iron leaching from the composite was also under permissible limits. Photocurrent and Electrochemical Impedance Spectroscopy studies were performed to check the effective charge separation. The improved photocatalytic activity of the NiFe-CNT composite reflects (1) the synergy effect between NiFe2O4 and MWCNTs, (2) effective charge separation that retards the recombination of photogenerated charges, and (3) the generation of more reactive oxidation species (especially center dot OH radicals). Moreover, ease of separation due to the significant magnetic properties of the NiFe-CNT composite provides an efficient method to treat recalcitrant organic pollutant. | Nawaz, Mohsin; Shahzad, Asif; Tahir, Khurram; Kim, Jiho; Moztahida, Mokrema; Jang, Jiseon; Alam, Md.

| ○ | ○ | Article | PI-type event-triggered H∞ filter for networked T-S fuzzy systems using affine matched membership function approach | This paper handles a design of event-triggered H-infinity filter for T-S fuzzy systems in the connection of network communication. The sampled-data fuzzy filter, which take into account both the measurement output and the fuzzy consequent parameter as the sampled signal, is expressed as a fuzzy system with a time-varying delay including the event-triggering variable. Under these considerations, a novel proportional-plus-integral (PI) event triggering condition is proposed to alleviate network allocation. Based time-delay approach, the stability of the filtering error systems is guaranteed by a new Lyapunov Kravoskii functional and by employing generalized free-weighting matrix integral inequality. Furthermore, an affine matched membership based distributed-filter (AMDF) is designed to improve the H-infinity performance, utilizing affine transformed membership function as a membership function of fuzzy filter. The affine matched membership function relaxes the parameterized stability condition due to the deviation bounds of sampled fuzzy membership function between consecutive sampling times. To show the effectiveness of proposed method, the results are compared with the unused ones. (C) 2020 Elsevier Inc. All rights reserved. | Kwon, W.; Jin, Yongsik; Lee, S.

| ○ | ○ | Article | Polyvinylamine-loaded metal-organic framework MIL-101 for effective and selective CO2 adsorption under atmospheric or lower pressure | Recently, selective removal of CO2 from offgas of various industries is very important, and metal-organic frameworks (MOFs) have been actively studied as a potential adsorbent. In this study, a typical MOF with a high porosity, MIL-101, was modified by loading (via ship in a bottle technique) basic polymer, polyvinylamine (PVAm), for the first time, in order to improve the performances of MIL-101 in adsorption/capture of CO 2 from offgas. The obtained PVAm@MIL-101 showed highly increased selectivity (CO2/N-2) and capacity in CO2 adsorption under low pressure, when suitable quantity of PVAm was introduced. Or, the adsorption selectivity and capacity of PVAm(0.7)@MIL-101 were around 11 and 2.5 times to those of pristine MIL-101, respectively at 298 K. Moreover, the PVAm(0.7)@MIL-101 was readily recycled for continuous uses and had optimum isosteric heat of adsorption (- Delta H-ads = 35-50 kJ/mol) for a wide range of CO2 adsorption. Therefore, loading PVAm into porous MOFs can be recommended as an attractive way to improve the performances of the MOFs in CO2 adsorption/capture from offgas under low pressure. | Shin, Subin; Yoo, Dong Kyu; Bae, Youn-Sang; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, 50 Yonsei Ro, Seoul 03722, South Korea | ; Shin, Subin/MDT-8671-2025; Jhung, Sung/AAO-6683-2021 | 57207849464; 57201339246; 7201465967; 6701659467 | sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 389 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 2.45 | 2025-06-25 | 65 | 66 | Adsorption; CO2; Metal organic frameworks; MIL-101; Polyvinylamine | MIXED MATRIX MEMBRANES; CARBON-DIOXIDE CAPTURE; CO2/CH4 SELECTIVITY; FLUE-GAS; SEPARATION; ADSORBENT; CAPACITY; FUNCTIONALIZATION; REDUCTION; SORPTION | Adsorption; CO<sub>2</sub>; Metal organic frameworks; MIL-101; Polyvinylamine | Adsorption; Bottles; Organometallics; Adsorption selectivity; Isosteric heat of adsorption; Lower pressures; Metal organic framework; MIL-101; Polyvinylamines; Potential adsorbents; Selective removal; Carbon dioxide | English | 2020 | 2020-06-01 | 10.1016/j.cej.2019.123429 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Remarkable metal-organic framework composites for adsorptive removal of nitrogenous compounds from fuel | A metal-organic framework (MOF) composite ZIF-67(x)@H2N-MIL-125 [Z67(x)@M125] was designed and synthesized for the first time. The synthesis was optimized by the varying composition of the Z67 content (e.g., weight percent of Z67 was varied from 0 to 50% of the total amount of the main precursors for the M125) and reaction time (1-16 h). Adsorptive removal of organo-nitrogen compounds (ONCs) from model fuel was done after the detail characterization of the Z67(0-10)@M125 (composite with 0-10% of Z67). The Z67(5.0)@M125 (a MOF composite with 5% of Z67) was observed as the best material among the studied adsorbents for the tested adsorbates (ONCs). Moreover, the adsorption efficiency of the ONCs was further improved when Z67(5.0) @M125 was protonated. Importantly, the protonated Z67(5.0)@M125 showed the highest adsorption capacity, especially for IND, compared with any reported adsorbent so far, based on MOFs or activated carbon. Based on the adsorption results and the properties of the adsorbent/adsorbates, plausible adsorption mechanisms could be suggested. The developed Z67(5.0)@M125 can be readily recycled with negligible loss of performance. | Bhadra, Biswa Nath; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Bhadra, Biswa Nath/ABG-6935-2021; Jhung, Sung/AAO-6683-2021; Bhadra, Biswa/ABG-6935-2021 | 56982844300; 6701659467 | sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 398 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 0.56 | 2025-06-25 | 18 | 17 | Adsorption; Fuel; Mechanism; MOF composite; Organo-nitrogen compounds | LIQUID-HYDROCARBON STREAMS; SELECTIVE ADSORPTION; FUNCTIONAL-GROUPS; TRANSPORT SECTOR; DENITROGENATION; CATALYST; CARBON; DESULFURIZATION; SEPARATION; REDUCTION | Adsorption; Fuel; Mechanism; MOF composite; Organo-nitrogen compounds | Activated carbon; Nitrogen compounds; Nitrogen removal; Protonation; Adsorption capacities; Adsorption efficiency; Adsorption mechanism; Adsorptive removal; Loss of performance; Nitrogenous compounds; Organo nitrogen compounds; Weight percent; Adsorption | English | 2020 | 2020-10-15 | 10.1016/j.cej.2020.125590 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | S-nitrosated keratin composite mats with NO release capacity for wound healing | Wound repair is a dynamic and complex process that involves various interactions between repair cells, growth factors and the extracellular matrix. Nitric oxide (NO) plays a pivotal role in wound healing, including causing the contraction of wound surfaces, dilating blood vessels, participating in inflammation, and promoting collagen synthesis, angiogenesis, and fibroblast proliferation. Here, we prepared a novel keratin-based nitric oxide donor, called S-nitrosated keratin (KSNO). Then, KSNO was coelectrospun with polyurethane (PU) and gelatin (Gel) to produce PU/Gel/KSNO biocomposite mats. The prepared mats released NO without cytotoxicity, promoted the proliferation of L929 murine fibroblasts and human umbilical vein endothelial cells (HUVECs), and inhibited bacterial growth. These mats could also accelerate the cell adhesion and growth along the random arrangement of electrospun fibers, and simulate the structure of the natural extracellular matrix to provide good scaffolds for cell. The effect of PU/Gel/KSNO on promoting wound healing was investigated on a full-thickness excisional cutaneous wound model in rats. The results demonstrated that these mats accelerated wound healing without inflammatory reaction.

| ○ | ○ | Article | Selective CO2 adsorption over functionalized Zr-based metal organic framework under atmospheric or lower pressure: Contribution of functional groups to adsorption | Selective capture of CO2 from offgas is important to mitigate the global warming; and metal organic frameworks (MOFs) have been attractive in the capture because of huge porosity, ready functionalization and so on. In this study, a stable Zr-based MOF, MOF-808, was modified with ethylenediaminetetraacetic acid (EDTA) and further reacted with ethylenediamine (ED); and finally reduced with lithium aluminum hydride (LAH) to introduce several functional groups (FGs) onto the MOF. Moreover, the MOFs were applied in CO2 adsorption under low pressure. The efficiency of MOF-808 in CO2 capture was improved with EDTA loading; however, interestingly, further reaction of MOF-808-EDTA with ED causes a very much decrease in the efficiency. Importantly, the reduction of MOF-808-EDTA-ED with LAH (for MOF-808-EDTA-ED-R) leads to a remarkable increase in the performance of the MOF, for high CO2 adsorption capacity, CO2/N-2 selectivity and isosteric heat of adsorption. For example, MOF-808, MOF-808-EDTA, MOF-808-EDTA-ED and MOF-808-EDTA-ED-R showed CO2/N-2 IAST selectivity (from CO2/N-2 = 15/75) of 40, 48, 19 and 197, respectively, under 298 K and 1 atm. This unusual observation could be explained with the contribution of FGs and porosity. Or, amides in cyclic rings might be formed during reaction with ED; and the MOF with amides was poor in CO2 capture partly due to decreased porosity of the MOF; however, can be very effective in adsorption, after further reduction of amides to amines. This work shows the importance of modifications or FGs on MOFs in CO2 adsorption, or a simple reduction can increase the adsorption selectivity as much as 10 times, which might be helpful to mitigate the global warming. | Park, Jong Min; Yoo, Dong Kyu; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | ; Jhung, Sung/AAO-6683-2021 | 57193995796; 57201339246; 6701659467 | sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 402 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 2.9 | 2025-06-25 | 91 | 95 | Adsorption; Functional group; CO2; Metal organic frameworks; MOF-808 | CARBON-DIOXIDE CAPTURE; MIXED MATRIX MEMBRANES; POROUS MATERIALS; FLUE-GAS; MOF; SEPARATION; CONVERSION; AIR | Adsorption; CO<sub>2</sub>; Functional group; Metal organic frameworks; MOF-808 | Adsorption; Aluminum compounds; Amides; Amines; Carbon dioxide; Efficiency; Global warming; Lithium compounds; Metal-Organic Frameworks; Organic polymers; Organometallics; Porosity; Zirconium compounds; Adsorption selectivity; Ethylene diamine; Functionalizations; Functionalized; Isosteric heat of adsorption; Lithium aluminum hydride; Lower pressures; Metalorganic frameworks (MOFs); Ethylenediaminetetraacetic acid | English | 2020 | 2020-12-15 | 10.1016/j.cej.2020.126254 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Self-tuning tetragonal zirconia-based bimetallic nano(hydr)oxides as superior and recyclable adsorbents in arsenic-tolerant environment: Template-free in and ex situ synthetic methods, stability, and mechanisms | In this study, we aimed to decorate nano-ZrO2 on LaOx to enhance the architectural stability of LaOx for the uptake of both arsenate and arsenite in single solutions. LaOx was obtained as lanthanum methanoate (LaMe) from a simple solvothermal reaction of lanthanum and benzoic acid. The leaving group of formic acid was used as a reducing agent to grow ZrO2 over LaOx, which resulted in a nanocomposite denoted as ZrO2@x%LaMe. The de-arsenic behavior of this composite was compared with that of one-pot-synthesized La-ZrO2 and ZrO2@x%La(OH)(3), with La(OH)(3) being obtained commercially. Powder X-ray diffraction patterns showed that the ZrO2 structure was transformed from monoclinic to tetragonal during the formation of ZrO2@x%LaMe, La-ZrO2, and ZrO2@x%La(OH)(3). Among the synthesized nano-bimetallic composites, ZrO2@50%LaMe exhibited the highest adsorption densities for both arsenate and arsenite due to the uniform distribution of ZrO2 over the LaOx surface resulted in a larger Brunauer-Emmett-Teller specific surface area and a higher zeta potential charge. The synthesized nanocomposites were reused several times with the aid of 0.1 M HNO3 for maximizing the uptake of both arsenate and arsenite from water. Selectivity and the stability (pH) studies indicated that the nanocomposites were highly selective and showed zero-dissolution behavior, respectively. The results of this study suggested that these nanocomposites could be used as alternatives for many La-based adsorbent materials in practical applications. | Prabhu, Subbaiah Muthu; Sasaki, Keiko; Elanchezhiyan, S.

| ○ | Article | Stretchable and transparent supercapacitors based on extremely long MnO2/Au nanofiber networks | With the advances in the development of next-generation electronics, transparent and stretchable energy storage devices have received great attention due to their suitability for wearable electronics. However, it remains a great challenge to realize devices with high storage capacity and high degree of stretchability. This report describes a simple process for the fabrication of supercapacitors with areal capacitance of ~3.68 mF/cm2 and transmittance of ~60% of with high cycling stability tested over 8000 charging and discharging cycles. Extremely long MnO2/Au nanofiber networks electrode based on electrospinning is fabricated. This structure of the electrode enables the device to be highly stretchable. Additionally, the porous nature of MnO2 as well as the multilayer stacking structure of MnO2/Au nanofibers electrode enhances the areal capacitance of devices. As a prototype device, the supercapacitor in this study suggests a promising application for next-generation energy storage devices in transparent and wearable electronics. © 2019 Elsevier B.V. | Lee, Yein; Chae, Sanghak; Park, Hyeji; Kim, Juhyeon; Jeong, Soo-Hwan | Department of Chemical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Chemical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Chemical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea, Advanced Instrumentation Institute, Korea Research Institute of Standards and Science, Daejeon, 34113, South Korea; Department of Chemical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Chemical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea | 57207016167; 57212017295; 57193897897; 57208757359; 7402425359 | shjeong@knu.ac.kr; | Chemical Engineering Journal | CHEM ENG J | 1385-8947 | 1873-3212 | 382 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2020 | 13.273 | 2.5 | 2.23 | 2025-06-25 | 45 | Electrospinning; Manganese oxide; Nanofiber networks; Stretchable supercapacitor; Transparent electrode | Capacitance; Electrospinning; Energy storage; Manganese oxide; Nanofibers; Supercapacitor; Wearable technology; Cycling stability; Multilayer stacking; Porous nature; Prototype devices; Storage capacity; Transparent electrodes | English | Final | 2020 | 10.1016/j.cej.2019.122798 | 바로가기 | 바로가기 | 바로가기 | ||||||||

| ○ | ○ | Article | Hybrid electrochemical microfiltration treatment of reverse osmosis concentrate: A mechanistic study on the effects of electrode materials | The reverse osmosis (RO) technology is promising as a key process for water reuse, but the RO brine (concentrate) needs proper treatments for minimal liquid disposals. This study investigated the potential of hybrid electrochemical microfiltration for the treatment of the RO concentrate from a municipal wastewater reuse plant. Two anodes (active Ir-RuOx and non-active Sb-SnO2) and two cathodes (stainless steel and carbon felt) were employed and compared in terms of the contaminants removal. The electrochemical microfiltration treatment achieved a substantial removal of color, turbidity, chemical oxygen demand, and fluorophores. However, the removal of the total nitrogen and organic carbon was limited. Then, mechanistic studies on the used electrode materials for the electrocatalysis of the RO concentrate were further conducted. The electrocatalysis that used a non-active anode improved the mineralization of the organics, whereas the active anode enhanced the denitrification. The combined use of the two anodes enabled the enhancement of the overall removal efficiencies. In addition, the oxidants (reactive chlorine/oxygen species) responsible for the organics and the nitrogen removals were elucidated. Overall, it was revealed that the electrochemical microfiltration that utilizes proper electrode combinations is a promising option for enhancing the treatment of RO concentrates with minimal disposals. | Mameda, Naresh; Park, Hyeona; Choo, Kwang-Ho | Kyungpook Natl Univ, Adv Inst Water Ind, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | Choo, Kwang-Ho/A-3456-2016; Mameda, Naresh/AAV-2711-2020 | 57192214360; 57213039681; 7102083272 | chookh@knu.ac.kr; | DESALINATION | DESALINATION | 0011-9164 | 1873-4464 | 493 | SCIE | ENGINEERING, CHEMICAL;WATER RESOURCES | 2020 | 9.501 | 2.6 | 0.49 | 2025-06-25 | 8 | 9 | Active anode; Electrocatalysis; Membrane filtration; Non-active anode; Reverse osmosis brine | MUNICIPAL WASTE-WATER; OXIDATION; DISINFECTION; COAGULATION; 1,4-DIOXANE; POLLUTANTS; SYSTEM | Active anode; Electrocatalysis; Membrane filtration; Non-active anode; Reverse osmosis brine | Anodes; Catalysis; Cathodes; Chemical oxygen demand; Electrocatalysis; Hybrid materials; Mechanics; Microfiltration; Nitrogen; Nitrogen removal; Organic carbon; Reverse osmosis; Sewage treatment plants; Tin alloys; Wastewater disposal; Wastewater reclamation; Wastewater treatment; Water conservation; Water filtration; Electrode material; Mechanistic studies; Municipal wastewaters; Non-active anodes; Removal efficiencies; Reverse osmosis concentrates; Reverse osmosis technologies; RO concentrate; electrochemical method; electrode; filtration; pollutant removal; reverse osmosis; wastewater treatment; Electrochemical electrodes | English | 2020 | 2020-11-01 | 10.1016/j.desal.2020.114617 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
