| ○ | ○ | Article | Mineral transformation and dissolution of jarosite coprecipitated with hazardous oxyanions and their mobility changes | Jarosite coprecipitation with hazardous oxyanions can attenuate the concentrations of these elements in acid mine drainage. However, jarosite can be easily transformed to goethite with changes in geochemical conditions. Consequently, the released oxyanions can greatly affect environments. The changes in the mineralogy and mobility of five oxyanions, namely AsO4, SeO3, SeO4, MoO4, and CrO4, which were coprecipitated with jarosite, are investigated herein during the mineral transformation. Our results show that the oxyanion species and the pH values greatly affect the mineral transformation and dissolution rates of jarosite-containing oxyanions. The transformation and dissolution rates of the jarosite samples at pH 8 are noticeably higher than those at pH 4. The X-ray diffraction results show that the CrO4 and SeO4 jarosites are as effectively transformed to goethite as the jarosite without oxyanions, while the SeO3 and AsO4 jarosites are least transformed, resulting in different sulfate and oxyanion concentrations in the solution. The oxyanions in jarosite are the main controlling factor in the mineral transformation and dissolution rates. In acid mine drainage, although CrO4 is easily attenuated by the jarosite precipitation, it has the highest mobility during the goethite transformation. On the contrary, AsO4 shows the opposite case. | Ryu, Jae-Geun; Kim, Yeongkyoo | Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea | 57417511800; 7410207179 | ygkim@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 427 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2022 | 13.6 | 3.5 | 1.55 | 2025-06-25 | 25 | 27 | Jarosite; Oxyanion; Mineral transformation; Trace element; Acid mine drainage | X-RAY-ABSORPTION; IRON; SCHWERTMANNITE; GOETHITE; SPECIATION; CHROMATE; DRAINAGE; ARSENATE; BEHAVIOR; SULFATE | Acid mine drainage; Jarosite; Mineral transformation; Oxyanion; Trace element | Chromium compounds; Dissolution; Drainage; Hazards; Minerals; Molybdenum compounds; Selenium compounds; Sulfur compounds; arsenic acid; chromium; ferric hydroxide; mineral; molybdic acid; selenium; Acid mine-drainage; Co-precipitated; Dissolution rates; Jarosites; Mineral dissolution; Mineral transformations; Mobility changes; Oxyanions; Traces elements; Transformation rates; anion; biotransformation; dissolution; element mobility; jarosite; mineral; precipitation (chemistry); transformation; acid mine drainage; Article; controlled study; dissolution; hazardous waste; mineralogy; pH; precipitation; reaction time; X ray diffraction; Trace elements | English | 2022 | 2022-04-05 | 10.1016/j.jhazmat.2022.128283 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Pore creation nanoarchitectonics from non-porous metal-organic framework to porous carbon for adsorptive elimination of sulfanilamide and chloroxylenol from aqueous solution | Three isomeric metal-organic frameworks (MOFs) such as MAF-5, -6, and -32 (with the same composition of [Zn(2-ethylimidazole)(2)]) were carbonized and, for the first time, activated further with KOH to prepare highly porous MOF-derived carbons (MDCs). Importantly, MDC-32 derived from non-porous MAF-32 had the highest porosity among the three MDCs although it has the lowest porosity when no KOH activation was done. Adsorption of sulfanilamide and chloroxylenol from water was investigated with the MDCs. Among the MDCs, MDC-32 showed the best adsorptive performance for sulfanilamide and chloroxylenol. Moreover, MDC-32, had the highest adsorption capacity (256 mg/g) for removing sulfanilamide from water, compared with any adsorbent reported so far. Based on the observed adsorption and properties of the adsorbate and adsorbent, pi-pi and hydrogen bonding interactions, with a slight contribution of repulsive electrostatic interaction, could be suggested as the mechanism for the sulfanilamide adsorption over the MDC-32. Moreover, the MDC-32 could be recycled easily for up to four cycles. It could be suggested that non-porous MOFs can be a good precursor for highly porous MDCs, if activated well using KOH, for example. Finally, MAF-32-derived carbon, MDC-32, might be suggested as a plausible adsorbent to eliminate organics such as sulfanilamide from water. | Mondol, Md.

| ○ | ○ | Article | Structural and functional characterization of an auxiliary domain-containing PET hydrolase from Burkholderiales bacterium | Biodegradation of polyethylene terephthalate (PET) is one of fundamental ways to solve plastic pollution. As various microbial hydrolases have an extra domain unlike PETase from Ideonella sakaiensis (IsPETase), research on the role of these extra domain in PET hydrolysis is crucial for the identification and selection of a novel PET hydrolase. Here, we report that a PET hydrolase from Burkholderiales bacterium RIFCSPLOWO2₀₂FULL₅₇₃₆ (BbPETase) with an additional N-terminal domain (BbPETaseAND) shows a similar hydrolysis activity toward microcrystalline PET and a higher thermal stability than IsPETase. Based on detailed structural comparisons between BbPETase and IsPETase, we generated the BbPETaseS335N/T338I/M363I/N365G variant with an enhanced PET-degrading activity and thermal stability. We further revealed that BbPETaseAND contributes to the thermal stability of the enzyme through close contact with the core domain, but the domain might hinder the adhesion of enzyme to PET substrate. We suggest that BbPETase is an enzyme in the evolution of efficient PET degradation and molecular insight into a novel PET hydrolase provides a novel strategy for the development of biodegradation of PET. | Sagong, Hye-Young; Kim, Seongmin; Lee, Donghoon; Hong, Hwaseok; Lee, Seul Hoo; Seo, Hogyun; Kim, Kyung-Jin | Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat BioRes Grp, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Inst Microorganisms, Daegu 41566, South Korea; Pohang Univ Sci & Technol, Pohang Accelerator Lab, Pohang, South Korea | Kim, Seok-Hwan/G-9981-2015; Kim, Kyung-Jin/MVY-3405-2025 | 57006554000; 57204760454; 57207418964; 57208592877; 57205261937; 57189697998; 55510867400 | kkim@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 429 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2022 | 13.6 | 3.5 | 1.61 | 2025-06-25 | 26 | 27 | Polyethylene terephthalate; Biological degradation; PET hydrolase; Auxiliary domain | CUTINASE-CATALYZED HYDROLYSIS; THERMOBIFIDA-FUSCA CUTINASE; POLYETHYLENE TEREPHTHALATE; IDEONELLA-SAKAIENSIS; POLY(ETHYLENE-TEREPHTHALATE); DEGRADATION; FUSION; POLYETHYLENETEREPHTHALATE; DEGRADES; DOCKING | Auxiliary domain; Biological degradation; PET hydrolase; Polyethylene terephthalate | Burkholderiales; Hydrolases; Hydrolysis; Polyethylene Terephthalates; Bacteria; Hydrolases; Hydrolysis; Plastic bottles; Polyethylene terephthalates; Thermodynamic stability; hydrolase; polyethylene terephthalate; polyethylene terephthalate; Auxiliary domain; Biological degradation; Functional characterization; High thermal stability; Hydrolysis activity; Microcrystallines; N-terminal domains; Plastic pollutions; Polyethylene terephthalate hydrolase; Structural characterization; bacterium; biodegradation; enzyme; hydrolysis; amino terminal sequence; Article; Burkholderiales; comparative study; depolymerization; enzyme activity; microbial degradation; nonhuman; protein hydrolysis; thermostability; chemistry; hydrolysis; metabolism; Biodegradation | English | 2022 | 2022-05-05 | 10.1016/j.jhazmat.2022.128267 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Advances in algal biomass pretreatment and its valorisation into biochemical and bioenergy by the microbial processes | Urbanization and pollution are the major issues of the current time own to the exhaustive consumption of fossil fuels which have a detrimental effect on the nation's economies and air quality due to greenhouse gas (GHG) emissions and shortage of energy reserves. Algae, an autotrophic organism provides a green substitute for energy as well as commercial products. Algal extracts become an efficient source for bioactive compounds having antimicrobial, anti-oxidative, anti-inflammatory, and anti-cancerous potential. Besides the conventional approach, residual biomass from any algal-based process might act as a renewable substrate for fermentation. Likewise, lignocellulosic biomass, algal biomass can also be processed for sugar recovery by different pre-treatment strategies like acid and alkali hydrolysis, microwave, ionic liquid, and ammonia fiber explosion, etc. Residual algal biomass hydrolysate can be used as a feedstock to produce bioenergy (biohydrogen, biogas, methane) and biochemicals (organic acids, polyhydroxyalkanoates) via microbial fermentation. | Bhatia, Shashi Kant; Ahuja, Vishal; Chandel, Neha; Gurav, Ranjit; Bhatia, Ravi Kant; Govarthanan, Muthusamy; Tyagi, Vinay Kumar; Kumar, Vinod; Pugazendhi, Arivalagan; Banu, J.

| ○ | ○ | Article | An economical robust algorithm for solving 1D coupled Burgers' equations in a semi-Lagrangian framework | In this study, we propose an efficient algorithm for solving one-dimensional coupled viscous Burgers' equations. One of the main accomplishments of this study is to develop a stable high-order algorithm for the system of reaction-diffusion equations. The algorithm is "robust" because it is designed to prevent non-physical oscillations through an iteration procedure of a block Gauss-Seidel type. The other is to develop an efficient algorithm for the Cauchy problem. For this, we first find half of the upstream points by adopting a multi-step q th-order (q = 2 , 3) error correction method. The algorithm is also "economical" in the sense that an interpolation strategy for finding the remaining upstream points is designed to dramatically reduce the high computational cost for solving the nonlinear Cauchy problem without damage to the order of accuracy. Three benchmark problems are simulated to investigate the accuracy and the superiority of the proposed method. It turns out that the proposed method numerically has the q th-order temporal and 4th-order spatial accuracies. In addition, the numerical experiments show that the proposed method is superior to the compared methods in the sense of the computational cost. (c) 2022 Elsevier Inc.

| ○ | ○ | Article | Body-Mediated Bioelectronics for Zero-Powered Ion Release and Electrical Stimulation | Development of bioelectronics that can be used permanently in daily life without additional power sources is an important research goal. To this end, myriad permanent systems based on energy harvesting have been reported; however, there are still limitations, such as restrictions regarding specific installations and connections to lines. Herein, we present a new type of bioelectronics based on body-mediated energy transfer for zero-powered ion release and electrical stimulation. Body-mediated bioelectronics (BMB) is a new system that transfers electrical energy generated by various human activities (e.g., walking, using laptop) through the human body without energy loss. To apply the BMB to human skin, a biocompatible and skin-adhesive soft ion-diffusive hydrogel (IDH) was utilized as the bioelectrode. Finally, a BMB patch composed of IDHs with an iontophoretic structure was applied to the human body, and zero-powered electrical stimulation as well as active ion emission were implemented in daily life. | Jung, Sungwon; Yong, Hyungseok; Park, Sohyeon; Kim, Dongchang; Ryu, Seokgyu; Kim, Yang-Hee; Choi, Bumgyu; Choi, Woojin; Lee, Joon-Seok; Yoo, Jeeyoung; Hong, Jinkee; Lee, Sangmin | Yonsei Univ, Sch Chem & Biomol Engn, Seoul 03722, South Korea; Chung Ang Univ, Sch Mech Engn, Seoul 06974, South Korea; Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Univ Southampton, Inst Dev Sci, Bone & Joint Res Grp, Ctr Human Dev Stem Cells & Regenerat, Southampton SO16 6YD, Hants, England | ; LEE, JIN/Q-3108-2018; park, sohyeon/IST-1935-2023; Jung, Sungwon/KHX-0459-2024; Kim, Yang-hee/C-3687-2013; Yoo, Jeeyoung/AAH-1359-2019 | 55556647600; 57034860700; 57193811300; 57419358000; 57192435552; 57054351700; 57279141200; 57199407712; 57471526400; 56046607500; 14053752700; 58374505000 | jinkee.hong@yonsei.ac.kr;slee98@cau.ac.kr; | ACS ENERGY LETTERS | ACS ENERGY LETT | 2380-8195 | 7 | 11 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 22 | 3.6 | 0.53 | 2025-06-25 | 7 | 7 | HYDROGELS; FIELDS | Adhesives; Biocompatibility; Energy dissipation; Ions; Daily lives; Electrical energy; Electrical stimulations; Energy-transfer; Human activities; Human bodies; Ion release; On-body; Power sources; Research goals; Energy harvesting | English | 2022 | 2022-10-20 | 10.1021/acsenergylett.2c01968 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Catalytic pyrolysis for upgrading silver grass (Miscanthus sinensis) and carbon dioxide into flammable gases | This study proposes a sustainable hydrogen production platform using a fast-growing and inedible biomass waste, silver grass (Miscanthus sinensis). Pyrolysis of silver grass waste (SGW) was investigated using CO2 as a co-feedstock, focusing on the distribution of hydrogen in different products. When the catalyst was absent, hydrogen element distribution to H-2 gas during pyrolysis of SGW at 800 degrees C reached 10 wt%. During pyrolysis with the Ni/SiO2 catalyst, 60.3 wt% of hydrogen was converted into H-2 gas, and 7.3 wt% of hydrogen was distributed in gaseous hydrocarbons at 600 degrees C. Owing to the addition of CO2, CO production was promoted by the catalytic conversion of CO2 and volatile matter. Notably, CO2 has been proven to be a useful reactant for producing value-added CO. Thus, catalytic pyrolysis in the presence of CO2 can be considered as a renewable approach to produce flammable gases with the mitigation of CO2 emissions. | Lee, Sangyoon; Jung, Sungyup; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Kwon, Eilhann/AGY-3339-2022; Lee, Sang/ABC-8385-2020 | 57214885455; 55073290800; 9240622100 | ek2148@hanyang.ac.kr; | BIORESOURCE TECHNOLOGY | BIORESOURCE TECHNOL | 0960-8524 | 1873-2976 | 365 | SCIE | AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS | 2022 | 11.4 | 3.6 | 0.35 | 2025-06-25 | 7 | 6 | Waste-to-energy; Hydrogen; Catalysis; Pyrolysis; Circular bioeconomy | BIOMASS; DEMAND; FUELS | Catalysis; Circular bioeconomy; Hydrogen; Pyrolysis; Waste-to-energy | Biomass; Carbon Dioxide; Catalysis; Gases; Hydrogen; Poaceae; Pyrolysis; Silicon Dioxide; Silver; Carbon dioxide; Catalysts; Hydrogen production; Nickel compounds; Silver; biofuel; carbon dioxide; carbon monoxide; hydrocarbon; hydrogen; methane; nickel; nitrogen; pyrolytic oil; unclassified drug; vegetable oil; volatile agent; hydrogen; silicon dioxide; silver; Biomass wastes; Catalytic pyrolysis; Circular bioeconomy; Element distribution; Flammable gas; Gaseous hydrocarbon; Miscanthus sinensis; Ni/SiO 2 catalyst; Waste to energy; ]+ catalyst; carbon dioxide; catalysis; catalyst; grass; hydrogen; pyrolysis; temperature effect; Article; atmosphere; biocatalyst; biomass conversion; biotechnological production; carbon dioxide emission; comparative study; concentration (parameter); differential thermal analysis; elemental analysis; Miscanthus sinensis; nonhuman; pyrolysis; renewable energy; temperature; thermogravimetry; biomass; catalysis; gas; Poaceae; Pyrolysis | English | 2022 | 2022-12 | 10.1016/j.biortech.2022.128153 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Deep learning-based optimization of a microfluidic membraneless fuel cell for maximum power density via data-driven three-dimensional multiphysics simulation | A deep learning-based method for optimizing a membraneless microfluidic fuel cell (MMFC) performance by combining the artificial neural network (ANN) and genetic algorithm (GA) was for the first time introduced. A three-dimensional multiphysics model that had an accuracy equivalent to experimental results (R-2 = 0.976) was employed to generate the ANN's training data. The constructed ANN is equivalent to the simulation (R-2 = 0.999) but with far better computation resource efficiency as the ANN's execution time is only 0.041 s. The ANN model is then used by the GA to determine the inputs (microchannel length = 10.040 mm, width = 0.501 mm, height = 0.635 mm; temperature = 288.210 K, cell voltage = 0.309 V) that lead to the maximum power density of 0.263 mWcm(-2) (current density of 0.852 mAcm(-2)) of the MMFC. The ANN-GA and numerically calculated maximum power densities differed only by 0.766%. | Dang Dinh Nguyen; Thinh Quy Duc Pham; Tanveer, Muhammad; Khan, Haroon; Park, Ji Won; Park, Cheol Woo; Kim, Gyu Man | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Natl Res Inst Mech Engn, 4 Pham Van Dong St, Hanoi, Vietnam; Thu Dau Mot Univ, Inst Strategies Dev, 06 Tran Van On, Phu Hoa, Binh Duong, Vietnam | Tanveer, MuhammadShahbaz/LUY-0421-2024 | 57447274900; 57447525900; 23486949200; 14521310700; 59878018000; 7408416474; 55664733000 | gyuman.kim@knu.ac.kr; | BIORESOURCE TECHNOLOGY | BIORESOURCE TECHNOL | 0960-8524 | 1873-2976 | 348 | SCIE | AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS | 2022 | 11.4 | 3.6 | 1.41 | 2025-06-25 | 24 | 24 | Artificial neural network; Membraneless microfluidic fuel cells; Genetic algorithm; Maximum power density | ARTIFICIAL NEURAL-NETWORK; LAMINAR-FLOW; PERFORMANCE; CHANNEL | Artificial neural network; Genetic algorithm; Maximum power density; Membraneless microfluidic fuel cells | Computer Simulation; Deep Learning; Microfluidics; Neural Networks, Computer; Temperature; Deep learning; Fuel cells; Learning algorithms; Microfluidics; Neural networks; Data driven; Fuel cell performance; Learning-based methods; Maximum power density; Membraneless; Membraneless fuel cell; Membraneless microfluidic fuel cell; Microfluidic fuel cell; Multiphysics simulations; Optimisations; artificial neural network; fuel cell; genetic algorithm; machine learning; numerical model; article; artificial neural network; current density; deep learning; genetic algorithm; human cell; killer cell; simulation; computer simulation; microfluidics; temperature; Genetic algorithms | English | 2022 | 2022-03 | 10.1016/j.biortech.2022.126794 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of type of coagulants on removal efficiency and removal mechanisms of antibiotic resistance genes in anaerobic digestion of primary sludge produced via a chemically enhanced primary treatment process | The potential impact of the trivalent coagulant cations on the removal mechanisms, removal efficiencies and removal patterns of antibiotic resistance genes (ARGs) during anaerobic digestion (AD) of chemically enhanced primary treatment sludge (CEPTS) was investigated using polyaluminium chloride (PACl), ferric chloride (FeCl3) and mixed FeCl3-PACl. The removal efficiency of 23 ARGs and intI1 improved to 72.1% in AD of primary sludge with 100 mg/L FeCl3 and was lowest (only 54.4 %) in AD of primary sludge with 25 mg/L PACl. The removal of ARGs in AD of CEPTS with addition of single or mixed types of Al-based coagulant began to increase rapidly at the onset of batch operation. On the other hand, both the rapid increase in the removal efficiency of ARGs in AD with FeCl3 and the maximum removal efficiency were attained later than in the other ADs. | Damtie, Mekdimu Mezmir; Shin, Jingyeong; Lee, Sungman; Park, Chang Min; Wang, Jinhua; Kim, Young Mo | Hanyang Univ, Dept Civil & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Shandong Agr Univ, Coll Resources & Environm, Tai An 271018, Shandong, Peoples R China | ; Damtie, Mekdimu/N-8777-2019; Kim, Young Mo/HKF-1374-2023; Park, Chang Min/CAA-8506-2022 | 57391179100; 57194702841; 57390763100; 57209588953; 55929379800; 57202258703 | youngmo@hanyang.ac.kr; | BIORESOURCE TECHNOLOGY | BIORESOURCE TECHNOL | 0960-8524 | 1873-2976 | 346 | SCIE | AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS | 2022 | 11.4 | 3.6 | 0.82 | 2025-06-25 | 14 | 14 | Antibiotic resistance genes (ARGs); Coagulants (FeCl3 and PACl); Anaerobic digestion (AD); Chemically enhanced primary treatment sludge (CEPTS) | WASTE; COMMUNITY; CHLORIDE; FATE | Anaerobic digestion (AD); Antibiotic resistance genes (ARGs); Chemically enhanced primary treatment sludge (CEPTS); Coagulants (FeCl<sub>3</sub> and PACl) | Anaerobiosis; Anti-Bacterial Agents; Drug Resistance, Microbial; Genes, Bacterial; Sewage; Waste Water; Anaerobic digestion; Antibiotics; Chlorination; Chlorine compounds; Coagulation; Efficiency; Genes; Sludge digestion; antibiotic agent; biogas; carbapenemase; chloramphenicol; coagulating agent; copper; fertilizer; florfenicol; gentamicin; iron; macrolide; RNA 16S; sulfonamide; tetracycline; titanium; antiinfective agent; Anerobic digestion; Antibiotic resistance gene; Antibiotic resistance genes; Chemically enhanced primary treatment; Chemically enhanced primary treatment sludge; Coagulant (fecl3 and polyaluminum chloride); Poly(aluminum chloride); Primary sludge; Removal efficiencies; Removal mechanism; anaerobic digestion; antibiotic resistance; coagulation; pollutant removal; polymer; Article; Bacteroidetes; biodegradation; bioremediation; digestion; Firmicutes; flocculation; Fusobacteria; gene; inhibition constant; integron; Methanosaeta; Methanosarcina; Methanospirillum; Nitrospirae; nonhuman; oxygen consumption; particulate matter; prevalence; scientific literature; sludge; soil microflora; suspended particulate matter; thermal conductivity; anaerobic growth; antibiotic resistance; bacterial gene; sewage; wastewater; Iron compounds | English | 2022 | 2022-02 | 10.1016/j.biortech.2021.126599 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluation of growth responses of six gymnosperm species under long-term excessive irrigation and traits determining species resistance to waterlogging | In the era of extreme weather events, plant resistance to excessive water should be considered for plantations in frequently flooded areas to ensure their maximum survival and conservation of natural habitats. Therefore, we quantified the resistance to excessive irrigation (REI) in seedlings of six conifer species on the basis of their morphological, physiological, and biochemical traits. Two different irrigation regimes, natural precipitation as a control treatment and additional irrigation by sprinklers (30.89 +/- 2.80% above natural precipitation) as excessive irrigation, were applied for three consecutive years. The changes in the morphological, physiological, and biochemical traits under long-term excessive irrigation were species-specific. There were three distinct responses in biomass accumulation: drought-susceptible Chamaecyparis obtusa and Abies holophylla significantly increased their aboveground and underground biomass and showed a strong REI; Pinus thunbergii and P. densiflora, both resistant to drought, significantly decreased their aboveground and underground biomass and showed a weak REI. Larix kaempferi and Pinus koraiensis showed a medium REI with only aboveground biomass increment in the former and no biomass change in the latter. Plant biomass responses corresponded well with the changes in morphological, physiological, and biochemical traits. Biomass augmentation resulted from an increase in leaf size, leaf mass per area (LMA), maximum photosynthesis rate, and leaf water potential. Flavonoids, LMA, and stomatal conductance are the most important traits to assess species REI. This study elucidates plant responses to excess water and traits that drive their tolerance. The findings will help in the selection of species for flood-tolerant afforestation programs and establishment of sustainable forests in regions with increased frequency and severity of excessive rainfall. | Bhusal, Narayan; Adhikari, Arjun; Lee, Minsu; Han, Areum; Han, Ah Reum; Kim, Hyun Seok | Seoul Natl Univ, Dept Agr Forestry & Bioresources, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Natl Inst Ecol, Div Climate change Ecol, Maseo Myeon 33657, South Korea; Seoul Natl Univ, Interdisciplinary Program Agr & Forest Meteorol, Seoul 08826, South Korea; Natl Ctr Agro Meteorol, Seoul 08826, South Korea; Seoul Natl Univ, Res Inst Agr & Life Sci, Seoul 08826, South Korea; Natl Inst Ecol, Maseo Myeon 33657, South Korea; 1 Gwanak Ro, Seoul 08826, South Korea | Adhikari, Arjun/AAV-6297-2021; Bhusal, Narayan/AAE-9086-2019; Adhikari, Arjun/JCO-3306-2023 | 57199327486; 57195601415; 57197791550; 57216158934; 36843269500; 57203630265 | subalpine@nie.re.kr;cameroncrazies@snu.ac.kr; | AGRICULTURAL AND FOREST METEOROLOGY | AGR FOREST METEOROL | 0168-1923 | 1873-2240 | 323 | SCIE | AGRONOMY;FORESTRY;METEOROLOGY & ATMOSPHERIC SCIENCES | 2022 | 6.2 | 3.6 | 2.17 | 2025-06-25 | 19 | 20 | Biomass; Excessive water resistance; Leaf morphology; Flavonoids; Stomatal conductance | LEAF GAS-EXCHANGE; FLOODING TOLERANCE; PHOTOSYNTHETIC PERFORMANCE; RICINUS-COMMUNIS; PLANT HORMONES; ROOT TRAITS; WATER; DROUGHT; STRESS; SOIL | Biomass; Excessive water resistance; Flavonoids; Leaf morphology; Stomatal conductance | aboveground biomass; afforestation; coniferous tree; gymnosperm; irrigation system; photosynthesis; stomatal conductance; waterlogging | English | 2022 | 2022-08-15 | 10.1016/j.agrformet.2022.109071 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | High-Valent Iron Redox-Mediated Photoelectrochemical Water Oxidation | Fe3+ is widely used as a conduction band electron acceptor in the photocatalytic and photoelectrochemical (PEC) oxidation of water and various substrates. However, a question of the possible involvement of Fe3+ as a valence band hole acceptor has been raised. Herein, we demonstrate that the PEC water oxidation using oxide semiconductor (WO3, TiO2, and BiVO4; primarily WO3) films can proceed via the formation of high-valent iron species in the presence of aqueous Fe3+ ions at pH 1-3. The presence of Fe3+ (1-100 mM) enhances the photocurrent generation, O-2 evolution, and the Faradaic efficiency (FE) of similar to 90% with a biased WO3 electrode (1.23-1.88 V-RHE), whereas the formation of Fe2+ is significantly inhibited. An in situ transient absorption spectroscopic analysis reveals the formation of high-valent iron species. The selective oxidation of dimethyl sulfoxide to dimethyl sulfone using in situ high-valent iron species is achieved with an FE of similar to 98% in the PEC reaction with Fe3+. The proposed reaction mechanism should call for attention to the conventional role of Fe3+ in the PEC reaction. | Jeon, Tae Hwa; Han, Seungmok; Kim, Bupmo; Park, Cheolwoo; Kim, Wooyul; Park, Hyunwoong; Choi, Wonyong | Pohang Univ Sci & Technol POSTECH, Div Environm Sci & Engn, Pohang 37673, South Korea; Rice Univ, Dept Civil & Environm Engn, Houston, TX 77005 USA; Sungkyunkwan Univ, Dept Energy Sci, Suwon 16419, South Korea; Sookmyung Womens Univ, Dept Chem & Biol Engn, Seoul 04310, South Korea; Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea | Park, Hyunwoong/A-1247-2012; Choi, Wonyong/F-8206-2010; Kim, Bupmo/LZI-1224-2025; KIM, WOOYUL/GLT-3776-2022 | 37099787500; 57368337300; 57211371072; 57193164048; 23485589100; 7601565583; 7402516297 | hwp@knu.ac.kr;wchoi@postech.edu; | ACS ENERGY LETTERS | ACS ENERGY LETT | 2380-8195 | 7 | 1 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 22 | 3.6 | 0.83 | 2025-06-25 | 12 | 11 | ELECTROCHEMICAL GENERATION; HYDROGEN-PEROXIDE; IRON(III) IONS; NITRIC-ACID; WO3; OXYGEN; FERRATE; PHENOL; TIO2; DEGRADATION | Absorption spectroscopy; Bismuth compounds; Dimethyl sulfoxide; Magnetic semiconductors; Oxidation; Oxide films; Oxide semiconductors; Photoelectrochemical cells; Titanium dioxide; Tungsten compounds; Vanadium compounds; Conduction band electrons; Electron-acceptor; Faradaic efficiencies; High-valent irons; Iron species; Photo-electrochemical oxidations; Photocatalytic oxidations; Photoelectrochemical reaction; Photoelectrochemical water oxidation; Water substrates; Spectroscopic analysis | English | 2022 | 2022-01-14 | 10.1021/acsenergylett.1c02430 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Regional sampled-data synchronization of chaotic neural networks using piecewise-continuous delay dependent Lyapunov functional | In this paper, a regional sampled-data synchronization criterion is proposed for the chaotic neural networks (CNNs) with input saturation using the piecewise-continuous delay dependent Lyapunov functional (PDDLF) approach. The aim of this work is to enlarge the region of attraction (ROA) of the synchronous state for CNNs with input saturation. Unlike existing works, the Lyapunov functional in the proposed approach is constructed from a polynomial with respect to the piecewise-continuous delay. Moreover, the proposed Lyapunov functional is combined with looped-functionals to derive the sufficient condition. The synchronization criterion is formulated in terms of sum of squares (SOS) programs, which reduces the infinite-dimensional linear matrix inequality (LMI) conditions to a finite number of SOS conditions. A numerical example is presented to illustrate the effectiveness and advantages of the proposed approach.(c) 2022 Elsevier Inc. All rights reserved. | Han, S. Y.; Kommuri, S. K.; Kwon, O. M.; Lee, S.

| ○ | ○ | Article | The relationship between quorum sensing dynamics and biological performances during anaerobic membrane bioreactor treatment | Anaerobic membrane bioreactors (AnMBRs) enhance carbon neutrality with biomethane recovery from waste-water; however, microbial signaling, which may affect biological performances, was poorly understood. Here, we thus evaluate quorum sensing (QS) dynamics while monitoring acyl-homoserine lactones (AHLs) and autoinducer-2 (AI-2) levels during long-term AnMBR operations after sludge inoculation. Significant organic removal and methane production were achieved with the reactor startup. Signal molecule levels varied with transient organic loading rates, depending on their types. A starving condition may cause an increase in short -and medium-chain AHLs and AI-2. Biopolymers, biosolids, volatile fatty acids, and alkalinity levels had positive correlations with short-and medium-chain AHLs and AI-2, whereas methane production had positive correla-tions with long-chain AHLs. The principal component analysis of QS signal composition and biological perfor-mance data explains their interconnectivity. The findings of this study help to understand that QS signals regulate metabolic pathways in addition to microbial group behaviors. | Shah, Syed Salman Ali; Park, Hyeona; Park, Hyung-June; Kim, Jinwoo; Mameda, Naresh; 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; Koneru Lakshmaih Educ Fdn, Dept Chem, Collage Engn, Vaddeswaram 522302, Andhra Pradesh, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak ro, Daegu 41566, South Korea | ; Mameda, Dr. Naresh/AAV-2711-2020; Mameda, Naresh/AAV-2711-2020; Shah, Syed Salman Ali/JCE-1663-2023; Choo, Kwang-Ho/A-3456-2016 | 57215722996; 57213039681; 57213039678; 57901150400; 57192214360; 7102083272 | chookh@knu.ac.kr; | BIORESOURCE TECHNOLOGY | BIORESOURCE TECHNOL | 0960-8524 | 1873-2976 | 363 | SCIE | AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS | 2022 | 11.4 | 3.6 | 0.77 | 2025-06-25 | 11 | 13 | Anaerobic membrane bioreactor; Quorum sensing; Acyl-homoserine lactones; Autoinducer-2 (AI-2); Biomethane | WASTE-WATER TREATMENT; BIOFOULING CONTROL; METHANE | Acyl-homoserine lactones; Anaerobic membrane bioreactor; Autoinducer-2 (AI-2); Biomethane; Quorum sensing | Acyl-Butyrolactones; Anaerobiosis; Bioreactors; Biosolids; Carbon; Methane; Quorum Sensing; Sewage; Waste Water; Bioconversion; Biopolymers; Bioreactors; Esters; Methane; Principal component analysis; Signal analysis; Wastewater treatment; biopolymer; fatty acid; methane; n acylhomoserine lactone; volatile fatty acid; carbon; gamma butyrolactone derivative; N-octanoylhomoserine lactone; Acyl-homoserine lactone; Anaerobic membrane bioreactor; Autoinducer-2; Biological performance; Biomethane; Homoserine lactones; Methane production; Positive correlations; Quorum-sensing; alkalinity; bioreactor; membrane; methane; principal component analysis; sludge; alkalinity; Article; biosolid; controlled study; inoculation; quorum sensing; sludge; anaerobic growth; bioreactor; metabolism; sewage; wastewater; Volatile fatty acids | English | 2022 | 2022-11 | 10.1016/j.biortech.2022.127930 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Uncertainty and disturbance estimator-based resilient tracking control design for fuzzy semi-Markovian jump systems | The focus of this paper is on solving the state tracking control problem for a class of fuzzy semi-Markovian jump systems with the aid of fuzzy modeling approach. Besides, the impact of both unexpected disturbances and uncertainties in fuzzy semi-Markovian jump systems is considered. In particular, the nonlinearity in the addressed system is represented by the T-S fuzzy model, wherein the disturbances and uncertainties are estimated by precisely considering uncertainty and disturbance estimator (UDE)-based control approach. Whilst, the desired fuzzy rule-based mode-dependent control law is formulated by exploiting the parallel distributed compensation strategy and estimated output of disturbances and uncertainties. In the proposed tracking control scheme, the resilient strategy is considered to overcome the impact of gain perturbations. Further, in terms of LMIs, a set of sufficient constraints is derived in accordance with the appropriate selection of mode dependent fuzzy rule-based Lyapunov function. Under which, the asymptotic tracking and enhanced disturbance rejection performances are guaranteed for the system under consideration. Notably, the desired control gain matrices are determined by solving the derived sufficient conditions via MATLAB LMI toolbox. Conclusively, a single-link robot arm model is adopted to justify the practicability and efficacy of the theoretical findings.(c) 2022 Published by Elsevier Inc. | Harshavarthini, S.; Kwon, O.
