○ ○ Article ⓘ Titanium nitride@nitrogen-enriched porous carbon derived from metal-organic frameworks and melamine: A remarkable oxidative catalyst to remove indoles from fuel ⓘ Titanium nitride (TiN) catalysts, supported on nitrogen-enriched carbon, were prepared via carbonization of a Ti-based metal-organic framework (MOF)/melamine mixture. The prepared catalysts were applied first to the oxidation of indoles as a potential catalyst and showed remarkable performance in oxidative denitrogenation (ODN) of fuel. For example, a developed catalyst, TiN@CN-2, has a high turnover frequency (58.1 h(-1)), the lowest activation energy (31.0 kJ.mol(-1)), and reusable catalytic performance, rendering it a competitive catalyst for ODN. Based on experimental studies (scavenger and electron spin resonance) and theoretical calculations, remarkable performance of TiN@CN-2 in ODN could be attributed to a nonradical mechanism involving active Ti-peroxo species. Additionally, compared with titanium oxides, titanium nitrides have a higher efficiency in H2O2 activation and the formation of Ti-peroxo species. Therefore, TiN, particularly when supported on nitrogen-enriched carbon (such as TiN@CN), could be proposed as a potential catalyst for oxidation reactions, including ODN. Finally, this work will pave the way for both a new oxidation catalyst and a facile synthesis of metal nitrides. ⓘ Mondol, Md.

○ ○ Article ⓘ Viable strategy to minimize trap states of patterned oxide thin films for both exceptional electrical performance and uniformity in sol-gel processed transistors ⓘ A sustainable water etchant-based photopatterning method is proposed to achieve simultaneous oxide film patterning and remarkably minimize trap states of dielectric and semiconductor oxide films. By exquisitely controlling each processing parameter, well-defined aluminum oxide (AlOx) dielectric and indium oxide (InOx) semiconductor patterns are formed, despite using acid-free pure water etchant. The water etchant not only dissolves the nonultraviolet-irradiated regions but also promotes an effective hydrolysis reaction of irradiated regions, thereby forming low-defect oxide patterns. As a result, frequency-stable AlOx capacitors with low leakage current and high-performance bias-stable InOx TFTs with low activation energy are fabricated. In particular, photopatterned enhancement-mode InOx TFTs exhibit remarkably improved electrical properties, stability, and uniformity-15-fold higher saturation mobility and remarkably low coefficient of variation of 12.04 cm2 V-1 s-1 and 25.26%, respectively- compared with nonpatterned TFTs. With the proposed method, 3V operating high-performance InOx/AlOx TFTs are successfully fabricated at a low processing temperature of 250 degrees C. ⓘ Kim, Do-Kyung; Seo, Kyeong-Ho; Kwon, Dae-Hyeon; Jeon, Sang-Hwa; Hwang, Yu-Jin; Wang, Ziyuan; Park, Jaehoon; Lee, Sin-Hyung; Jang, Jaewon; Kang, In Man; Zhang, Xue; Bae, Jin-Hyuk ⓘ Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Hallym Univ, Dept Elect Engn, Chunchon 24252, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Shandong Univ Sci & Technol, Coll Ocean Sci & Engn, Qingdao 266590, Peoples R China ⓘ Lee, Sin-Hyung/ABD-6425-2022 ⓘ 57984042900; 57211978931; 57222761479; 57552166800; 57553088900; 57552166900; 55717156300; 57226880204; 57194107504; 7203062678; 55949859900; 35326180700 ⓘ jhbae@ee.knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 441 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2022 15.1 3.2 0.63 2025-06-25 ⓘ 10 10 Metal-oxides; Thin-film transistors; Sol -gel process; Patterning; High electrical performance ⓘ LOW-TEMPERATURE; TRANSPARENT; MOBILITY; FACILE; DIELECTRICS; ACRYLATE; LAYER; TFTS ⓘ High electrical performance; Metal-oxides; Patterning; Sol–gel process; Thin-film transistors ⓘ Activation energy; Alumina; Aluminum oxide; Indium compounds; Leakage currents; Oxide films; Processing; Sols; Thin film circuits; Thin films; Water conservation; C. thin film transistor (TFT); Dielectric oxides; Electrical performance; Electrical uniformity; High electrical performance; Indium oxide; Metal-oxide; Oxide TFTs; Patterning; Trap state; Thin film transistors ⓘ English 2022 2022-08-01 10.1016/j.cej.2022.135833 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Constitutive modeling of commercial pure titanium sheet based on non-associated flow rule and differential hardening ⓘ The commercial-pure titanium (CP-Ti) sheet has attracted a great interest from biomedical and aerospace industries because of its strong mechanical advantages such as lightweight, high strength, good formability, and corrosion-resistance. However, strong anisotropic features, such as evolutionary yield surface and strength difference in tension and compression, of the CP-Ti require advanced constitutive modeling compared to standard advanced high strength steel sheets. This study took into account the differential hardening behavior and the changing R-value of CP-Ti sheet observed during the uniaxial tensile and bulge tests in developing a material model. The observed behaviors are modeled by Hill48 quadratic function based on non-associated flow rule with equivalent plastic work dependent evolutionary parameters. The developed material model was then implemented into a user material subroutine (VUMAT) for ABAQUS/EXPLICIT and used to simulate a circular deep drawing to verify the developed model. Simulation results are compared with those of a material model coupling Yld2000-2d yield function with associated flow rule. The comparison shows that the developed material model provides not only a good agreement with the experiment for yield and potential surfaces but also accurate predictions in forming simulations. ⓘ Kim, Jinjae; Pham, Quoc Tuan; Ha, Jinjin; Kim, Young Suk ⓘ Kyungpook Natl Univ, Grad Sch Mech Engn, Daegu 41566, South Korea; Univ New Hampshire, Dept Mech Engn, Durham, NH 03824 USA; Blekinge Inst Technol, Dept Mech Engn, Karlskrona, Sweden; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea ⓘ Pham, Quoc Tuan/AAH-8010-2019; Ha, Jinjin/AIC-8684-2022; Kim, Sang-Hoon/AAA-2248-2020 ⓘ 57209555877; 57191753992; 55000010500; 36065820800 ⓘ caekim@knu.ac.kr; ⓘ INTERNATIONAL JOURNAL OF MECHANICAL SCIENCES ⓘ INT J MECH SCI ⓘ 0020-7403 1879-2162 230 SCIE ENGINEERING, MECHANICAL;MECHANICS ⓘ 2022 7.3 3.3 1.92 2025-06-25 ⓘ 21 20 Commercial pure titanium; Differential hardening; Anisotropic yield function; Non-associated flow rule; Evolutionary parameters; Finite element analysis ⓘ ANISOTROPIC PLASTICITY MODEL; ALUMINUM-ALLOY SHEETS; ALPHA-TITANIUM; YIELD FUNCTION; DUCTILE DAMAGE; DEFORMATION; STRAIN; METAL; MICROSTRUCTURE; CRITERION ⓘ Anisotropic yield function; Commercial pure titanium; Differential hardening; Evolutionary parameters; Finite element analysis; Non-associated flow rule ⓘ Anisotropy; Constitutive models; Corrosion resistance; Finite element method; Hardening; High strength alloys; High strength steel; Sheet metal; Anisotropic yield functions; Commercial pure titanium; Differential hardening; Evolutionary parameters; Finite element analyse; Material modeling; Mechanical advantage; Non-associated flow rule; Pure titanium sheet; Yield surface; Aerospace industry ⓘ English 2022 2022-09-15 10.1016/j.ijmecsci.2022.107549 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Facile Design and Realization of Extremely Water-Repellent Surface by Mimicking the Greta oto's Wings ⓘ Herein, we report a Greta oto wing-inspired functional surface (GWFS). A master mold of the GWFS is easily fabricated using the direct laser writing (DLW) method and wet etching, and the GWFS surface is replicated by using UV imprint lithography. The GWFS has randomly arrayed-microstructures, and various experiments focusing on the wettability of the Greta oto's wing are carried out. Diverse characteristics of the GWFS related to the wettability of water droplet such as superhydrophobic surface (-163.6), low sliding angle (-8 degrees), and non-wetting surface are investigated. On the basis of these properties, the self-cleaning performance of GWFS is verified to have a high particle removal efficiency of-97%. Lastly, as a feasible application, an advanced quadcopter system with the GWFS, which can directly take off from the water surface, is proposed. This facile fabrication strategy and the admirable wettability properties of GWFS are expected to be used in various fields and provide insights into not only the surface mechanics but also the development of advanced future drones. ⓘ Lee, Sung Ho; Kang, Bong Su; Kwak, Moon Kyu ⓘ Univ Michigan, Dept Elect Elect & Comp Sci, Ann Arbor, MI 48109 USA; Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea ⓘ ; Kwak, Moon/AGQ-6058-2022 ⓘ 56195582600; 55330925300; 57203947984 ⓘ mkkwak@knu.ac.kr; ⓘ INTERNATIONAL JOURNAL OF MECHANICAL SCIENCES ⓘ INT J MECH SCI ⓘ 0020-7403 1879-2162 222 SCIE ENGINEERING, MECHANICAL;MECHANICS ⓘ 2022 7.3 3.3 1.06 2025-06-25 ⓘ 10 11 Greta oto; Direct laser writing; Superhydrophobic; Self-cleaning; Quadcopter ⓘ DRY ADHESIVES; WETTABILITY; FABRICATION; ROUGHNESS; HYDROPHOBICITY ⓘ Direct laser writing; Greta oto; Quadcopter; Self-cleaning; Superhydrophobic ⓘ Hydrophobicity; Molds; Wet etching; Wings; Direct laser writing; Functional surfaces; Gretum oto; Imprint lithography; Master molds; Property; Quadcopter; Self cleaning; UV imprint; Water repellent surfaces; Wetting ⓘ English 2022 2022-05-15 10.1016/j.ijmecsci.2022.107218 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Faults and Fault Ride Through strategies for grid-connected photovoltaic system: A comprehensive review ⓘ With the exponential penetration of Photovoltaic (PV) plants into the power grid, protection has gained exceptional importance in recent years for ensuring stability, reliability, security, and power quality of the power systems. Thus, to address these issues many countries have established new requirements in the form of grid codes for grid connection of PV plants. One of the main requirements of grid codes is Fault Ride Through (FRT) capability. FRT describes the power generator performance during and in post-fault circumstances. In this paper, an in-depth review is carried out on various scientific aspects of faults and FRT strategies available in the literature. First, various faults occurring in the grid-connected PV system are classified and compared along with a critical and analytical assessment of grid codes especially FRT requirements i.e., Low Voltage Ride Through (LVRT) and High Voltage Ride Through (HVRT) for various countries. Then, FRT approaches and strategies are classified and compared based on improved controller-based methods and external devices methods in detail. The existing FRT strategies are compared based on various aspects i.e., complexity, economically, and technically. After that, a case study that explains the complete design and implementation of conventional Crowbar, Bridge Type Fault Current Limiter (BFCL), and Switch Type Fault Current Limiter (STFCL) as an FRT strategies for 100 kW three-phase grid-connected PV system in MATLAB/Simulink is presented. A comparative assessment is also carried out among these strategies that validate the robust performance of BFCL and STFCL. Lastly, the conclusion is presented along with a brief proposal for future work. ⓘ Zeb, Kamran; Ul Islam, Saif; Khan, Imran; Uddin, Waqar; Ishfaq, M.; Busarello, Tiago Davi Curi; Muyeen, S.

○ ○ Article ⓘ Novel antitumor therapeutic strategy using CD4⁺ T cell-derived extracellular vesicles ⓘ Extracellular vesicles (EVs) mediate cell-cell crosstalk by carrying bioactive molecules derived from cells. Recently, immune cell-derived EVs have been reported to regulate key biological functions such as tumor progression. CD4(+) T cells orchestrate overall immunity; however, the biological role of their EVs is unclear. This study reveals that EVs derived from CD4(+) T cells increase the antitumor response of CD8(+) T cells by enhancing their proliferation and activity without affecting regulatory T cells (Tregs). Moreover, EVs derived from interleukin-2 (IL2)-stimulated CD4+ T cells induce a more enhanced antitumor response of CD8(+) T cells compared with that of IL2-unstimulated CD4(+) T cell-derived EVs. Mechanistically, miR-25-3p, miR-155-5p, miR-215-5p, and miR-375 within CD4(+) T cell-derived EVs are responsible for the induction of CD8(+) T cell-mediated antitumor responses. In a melanoma mouse model, the EVs potently suppress tumor growth through CD8(+)+ T cell activation. This study demonstrates that the EVs, in addition to IL2, are important mediators between CD4(+) and CD8(+) T cells. Furthermore, unlike IL2, clinically used as an antitumor agent, CD4(+) T cell-derived EVs stimulate CD8(+) T cells without activating Tregs. Therefore, CD4(+) T cell-derived EVs may provide a novel direction for cancer immunotherapy by inducing a CD8(+) T cell-mediated antitumor response. ⓘ Shin, Sanghee; Jung, Inseong; Jung, Dokyung; Kim, Christine Seulki; Kang, Sung -Min; Ryu, Suyeon; Choi, Sung-Jin; Noh, Soojeong; Jeong, Jongwon; Lee, Beom Yong; Park, Jun -Kook; Shin, Jiwon; Cho, Hanchae; Heo, Jong-Ik; Jeong, Youngtae; Ha Choi, Sun; Lee, Shin Yup; Baek, Moon -Chang; Yea, Kyungmoo ⓘ DGIST, Dept New Biol, Daegu 42988, South Korea; DGIST, New Biol Res Ctr, Daegu 43024, South Korea; Kyungpook Natl Univ, Sch Med, Exosome Convergence Res Ctr ECRC, Dept Mol Med,CMRI, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Lung Canc Ctr, Daegu 41404, South Korea ⓘ ; Jeong, Youngtae/M-7860-2015; Choi, Sung-Jin/ACC-8335-2022 ⓘ 57202494417; 57223306535; 57207487580; 57209806970; 59499667300; 59787801600; 57435770900; 57223308415; 57211276819; 57211266546; 57223285170; 57223303447; 57184674000; 57868263900; 56151139100; 57199723585; 49863712700; 7006013097; 12769131100 ⓘ mcbaek@knu.ac.kr;ykm31@dgist.ac.kr; ⓘ BIOMATERIALS ⓘ BIOMATERIALS ⓘ 0142-9612 1878-5905 289 SCIE ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS ⓘ 2022 14 3.3 4.3 2025-06-25 ⓘ 58 59 Cancer immunotherapy; Extracellular vesicles; Interleukin-2; CD4(+ )T cells; CD8(+) T cells ⓘ INTERLEUKIN-2; EXOSOMES; RESPONSES; HELP; LYMPHOCYTES; MICRORNAS; MOLECULES; IMMUNITY; MIR-375 ⓘ Cancer immunotherapy; CD4<sup>+</sup> T cells; CD8<sup>+</sup> T cells; Extracellular vesicles; Interleukin-2 ⓘ Animals; CD8-Positive T-Lymphocytes; Extracellular Vesicles; Interleukin-2; Mice; MicroRNAs; T-Lymphocytes, Regulatory; Chemical activation; Cytology; Diseases; Tumors; interleukin 2; microRNA; microRNA 155; microRNA 155 5p; microRNA 215 5p; microRNA 25 3p; microRNA 375; unclassified drug; interleukin 2; microRNA; Anti-tumors; Bioactive molecules; Cancer immunotherapy; CD4 T-cells; CD8+ T cell; Cell cross talks; Extracellular; Extracellular vesicle; Interleukin2 (IL2); Therapeutic strategy; animal experiment; animal model; animal tissue; Article; bioluminescence; cancer immunotherapy; cancer inhibition; CD4+ T lymphocyte; CD8+ T lymphocyte; cell activity; cell communication; cell viability assay; cellular immunity; controlled study; exosome; human; human cell; lymphocyte proliferation; lymphoma cell line; male; melanoma; mouse; mouse model; nonhuman; normal human; regulatory T lymphocyte; RNA isolation; T lymphocyte activation; therapy effect; Western blotting; wild type mouse; animal; T-cells ⓘ English 2022 2022-10 10.1016/j.biomaterials.2022.121765 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Power conversion performance of airborne wind turbine under unsteady loads ⓘ The study presents the systematic analysis of power conversion performance of the airborne wind turbine (AWT) using time-resolved air loads. The power harvesting behavior of the rotating blades in shell configuration is numerically investigated to analyze the influence of wind shear, yawed and tilted inflows at design operating conditions. An inherently unsteady scheme of the sliding mesh is incorporated to capture the complex flow field across the 3-bladed rotor. The fully-resolved computations closely match the expected results derived from the empirical calculations. The conversion performance supplements the turbine's power curve as a means of determining the distribution of aerodynamic forces, performance coefficients, vortex structure and shell thrust loadings. The time-marching response of the AWT gradually attains steady flow characteristics after two rotation periods when the wind shear profile is fully aligned with the rotor's axis of rotation. This yields a beneficial gain of 64% more power output with the rotor in shell configuration than those of the bare configuration. Meanwhile, cyclic fluctuations (+/- 21%) significantly undermine the continuous production of power in the case of skewed flow conditions. Moreover, the flow misalignment causes a localized shifting of effective forces on the rotor plane due to the intricate impact of the shell structure. ⓘ Ali, Qazi Shahzad; Kim, Man-Hoe ⓘ Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, IEDT, Daegu 41566, South Korea ⓘ ⓘ 57209058973; 55686310000 ⓘ shahzad@knu.ac.kr;manhoe.kim@knu.ac.kr; ⓘ RENEWABLE & SUSTAINABLE ENERGY REVIEWS ⓘ RENEW SUST ENERG REV ⓘ 1364-0321 1879-0690 153 SCIE ENERGY & FUELS;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY ⓘ 2022 15.9 3.3 0.74 2025-06-25 ⓘ 15 16 High altitude wind harvesting; Unsteady simulations; Renewable energy; Airborne wind turbines; Ducted wind turbines; Numerical modeling ⓘ AERODYNAMIC PERFORMANCE; ENERGY; OPTIMIZATION; DESIGN; SYSTEM; OUTPUT; CFD ⓘ Airborne wind turbines; Ducted wind turbines; High altitude wind harvesting; Numerical modeling; Renewable energy; Unsteady simulations ⓘ Aerodynamics; Energy harvesting; Shear flow; Shells (structures); Turbomachine blades; Airborne wind turbine; Ducted wind turbines; High altitude wind harvesting; High altitude winds; In-shell; Performance; Power conversion; Renewable energies; Unsteady simulations; Wind shears; Wind turbines ⓘ English 2022 2022-01 10.1016/j.rser.2021.111798 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Vibration measurement of a rotating cylindrical structure using subpixel-based edge detection and edge tracking ⓘ Acceleration sensors are commonly used for measuring the vibrations of structures. However, these contact-type sensors cannot be installed in some areas, such as on objects located in hazardous areas. Recently, non-contact-type measurement approaches, including photogrammetry techniques (e.g., point tracking, digital image correlation, and target-less approaches) have been introduced using images obtained from cameras. Nevertheless, photogrammetric approaches, e. g., point tracking and digital image correlation, have the same problem because targets or high contrast speckle patterns need to be mounted on structures. Instead, the target-less approaches for vibration measurement were developed and tested on static structures like bridges and other civil structures. However, analysts have rarely focused on the rotating axis of cylindrical structures, which is a general component of the rotation-based renewable power generation system. Therefore, in this paper, we introduced a subpixel-based vibration measurement method for a cylindrical rotating structure based on the video images acquired from a non-contact sensor. The frames were magnified, and subpixel-based edges were detected in each frame of the video. Then, using the proposed edge tracking technique, the coordinates of the edges in a region of interest were tracked throughout the video for measuring the vibrations. The proposed edge tracking technique keeps the track of the edge locations in the previous frame as well as the locations in the pixels of the current frame. To show the effectiveness of the proposed method, two simulation datasets and one real dataset were constructed. For the simulation datasets, we generated videos by adding sinusoidal noises together with random noise in an image that contains a static cylindrical object. For the real dataset, a video of a rotating cylindrical object was acquired. The results obtained using the proposed method were compared with the results obtained using the existing multi-interval second-order differential edge detection technique and partial area-based technique. From the simulation datasets, vibrations related to both the single and multiple frequencies were effectively detected by applying the proposed method. The proposed method had the lowest root mean square error (RMSE) calculated with the reference data compared to the existing methods. In the real dataset, we could demonstrate that the proposed method could effectively detect the vibrations on the rotating axis of a cylindrical structure with the exact locations of the edges while removing the non-interest edges or false edges. Moreover, during the frequency analysis, the peaks of the proposed method results were at the same frequency at which the object was rotating. Therefore, the proposed method can be a useful solution to detect the vibration of rotating structures located in hazardous areas with uneven backgrounds and uneven brightness. ⓘ Javed, Aisha; Lee, Hyeongill; Kim, Byeongil; Han, Youkyung ⓘ Seoul Natl Univ Sci & Technol, Dept Civil Engn, Seoul 01811, South Korea; Kyungpook Natl Univ, Sch Automot Engn, Sangju 37224, South Korea; Yeungnam Univ, Sch Mech Engn, Gyongsan 38541, South Korea ⓘ Javed, Aisha/LQK-3075-2024 ⓘ 57215897698; 8261483800; 56843890300; 55457676600 ⓘ javedaisha123@seoultech.ac.kr;hilee@knu.ac.kr;bikim@yu.ac.kr;han602@seoultech.ac.kr; ⓘ MECHANICAL SYSTEMS AND SIGNAL PROCESSING ⓘ MECH SYST SIGNAL PR ⓘ 0888-3270 1096-1216 166 SCIE ENGINEERING, MECHANICAL ⓘ 2022 8.4 3.3 3.73 2025-06-25 ⓘ 38 44 Vibration detection; Subpixel-based edge detection; Edge tracking; Photogrammetry; Target-less approach ⓘ DIGITAL-IMAGE-CORRELATION; PHOTOGRAMMETRY ⓘ Edge tracking; Photogrammetry; Subpixel-based edge detection; Target-less approach; Vibration detection ⓘ Edge detection; Image segmentation; Location; Mean square error; Motion analysis; Photogrammetry; Speckle; Strain measurement; Target tracking; Vibration measurement; Cylindrical structure; Digital image correlations; Edge tracking; Hazardous area; Point-tracking; Real data sets; Sub-pixels; Subpixel-based edge detection; Target-less approach; Vibration detection; Pixels ⓘ English 2022 2022-03-01 10.1016/j.ymssp.2021.108437 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Application of perovskite oxides and their composites for degrading organic pollutants from wastewater using advanced oxidation processes: Review of the recent progress ⓘ In the recent years, perovskite oxides are gaining an increasing amount of attention owing to their unique traits such as tunable electronic structures, flexible composition, and eco-friendly properties. In contrast, their catalytic performance is not satisfactory, which hinders real wastewater remediation. To overcome this shortcoming, various strategies are developed to design new perovskite oxide-based materials to enhance their catalytic activities in advanced oxidation process (AOPs). This review article is to provide overview of basic principle and different methods of AOPs, while the strategies to design novel perovskite oxide-based composites for enhancing the catalytic activities in AOPs have been highlighted.

○ ○ Article ⓘ Buckwheat hull-derived biochar immobilized in alginate beads for the adsorptive removal of cobalt from aqueous solutions ⓘ Buckwheat hull-derived biochar (BHBC) beads were synthesized by immobilizing biochar powder with alginate. Due to their cation-exchange ability, abundant functional groups, microporous structure, and large surface area, BHBC beads were successfully applied for the removal of cobalt from aqueous solution. The adsorption behavior followed pseudo-second-order kinetics and the Langmuir isotherm model showed a better fit to adsorption data than the Freundlich or Temkin isotherm models. The maximum adsorption capacity of BHBC beads was 24.0 mg/g at pH 5, 35 degrees C, and an initial cobalt concentration of 1.0 g/L, which was higher than those of previously reported natural resource-based adsorbents. In a fixed-bed column study, the effects of operating parameters such as flow rate, bed height, and bed diameter were investigated. Both the Thomas and Yoon-Nelson models were applied to the experimental data to predict the breakthrough curves using nonlinear regression. Overall, BHBC beads can be used as an efficient adsorbent for removal of radioactive cobalt from aqueous solution. ⓘ Lim, Youngsu; Kim, Bolam; Jang, Jiseon; Lee, Dae Sung ⓘ Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Radioact Waste Agcy, R&D Inst Radioact Wastes, 174 Gajeong Ro, Daejeon 34129, South Korea ⓘ ⓘ 57207112603; 57208922438; 56611137400; 55568524907 ⓘ jsjang@korad.or.kr;daesung@knu.ac.kr; ⓘ JOURNAL OF HAZARDOUS MATERIALS ⓘ J HAZARD MATER ⓘ 0304-3894 1873-3336 436 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2022 13.6 3.5 1.67 2025-06-25 ⓘ 28 30 Biochar; Alginate; Cobalt; Adsorption; Fixed-bed column ⓘ PYROLYSIS TEMPERATURE; PHYSICOCHEMICAL PROPERTIES; CO II; IONS; CADMIUM; CARBON; NANOCOMPOSITES; EQUILIBRIUM; BIOSORPTION; MECHANISMS ⓘ Adsorption; Alginate; Biochar; Cobalt; Fixed-bed column ⓘ Adsorption; Alginates; Charcoal; Cobalt; Fagopyrum; Kinetics; Water Pollutants, Chemical; Water Purification; Adsorption isotherms; Alginate; Cobalt; Crops; adsorbent; alginic acid; calcium; cellulose; charcoal; cobalt; hemicellulose; lignin; magnesium; nitrogen; potassium; sodium; alginic acid; charcoal; cobalt; Adsorption behaviour; Adsorptive removal; Alginate beads; Biochar; Cation exchanges; Fixed bed columns; Large surface area; Microporous structures; Pseudo second order kinetics; Synthesised; adsorption; aqueous solution; biochar; cobalt; immobilization; pollutant removal; adsorption; aqueous solution; Article; biomass; buckwheat; controlled study; flow rate; Fourier transform infrared spectroscopy; inductively coupled plasma mass spectrometry; natural resource; nonhuman; pore size distribution; precipitation; pyrolysis; thermodynamics; thermostability; zeta potential; adsorption; chemistry; Fagopyrum; kinetics; water management; water pollutant; Adsorption ⓘ English 2022 2022-08-15 10.1016/j.jhazmat.2022.129245 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Comparative assessment of chromate bioremediation potential of Pantoea conspicua and Aspergillus niger ⓘ The recent work aims at the use of Pantoea conspicua (MT5) and Aspergillus niger (CRS3) to assess their bioremediation potential and growth restoration of Helianthus annuus L. under chromate (Cr+6) stress. The growth of the P. conspicua and A. niger was tested in Cr+6 supplemented media. The strains can withstand up to 1200 and 900 ppm respectively in the media and effectively bio-transform it to nontoxic form. Supplemented metal's levels significantly decreased the growth attribute of H. annuus (p< 0.05). On the other hand, P. conspicua and A. niger rescued the host plant by establishing higher colonization frequency with the host roots. Moreover, MT5 biotransformed the toxic Cr+6 to non-toxic Cr+3 form in the rhizosphere. It also enhanced the host plant growth by producing phytohormones and ceasing Cr uptake and accumulation. Contrarily, CRS3 tends to accumulate and bio-transform metal in their hyphae. Nonetheless, both of the microbes tend to modulate phytohormones production and strengthening antioxidant system of the host. Improvement in the antioxidant system enabled the host plant to produce higher phenolics and flavonoids, and lower peroxidase. The associated plant species also exhibited higher ROS scavenging and lower ROS accumulation. Besides, the strains were able to produce higher amounts of phytohormones, including IAA, GA, and SA. Such activities rendered them as excellent phytostimulants, that can be used as biofertilizers in chromium polluted soils. ⓘ Qadir, Muhammad; Hussain, Anwar; Shah, Mohib; Lee, In Jung; Iqbal, Amjad; Irshad, Muhammad; Ismail; Sayyed, Aqib; Husna; Ahmad, Ayaz; Hamayun, Muhammad ⓘ Abdul Wali Khan Univ Mardan, Dept Bot, Garden Campus, Khyber Pakhtunkhwa, Pakistan; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 702701, South Korea; Abdul Wali Khan Univ Mardan, Dept Agr, Garden Campus, Khyber Pakhtunkhwa, Pakistan; Abdul Wali Khan Univ Mardan, Dept Biotechnol, Garden Campus, Khyber Pakhtunkhwa, Pakistan ⓘ Husna, Husna/ISS-6593-2023; Hamayun, Muhammad/B-1694-2010; Shah, Mohib/AEK-5703-2022; Ahmad, Ayaz/GVT-1025-2022; Ayaz, Ahmad/GVT-1025-2022; Hussain, Anwar/N-1605-2019; Iqbal, Amjad/E-2010-2014; Lee, In-Jung/GLS-0432-2022; Qadir, Muhammad/AFJ-3919-2022 ⓘ 57210988627; 35621772200; 56433799400; 16425830900; 10142205100; 57206301341; 57205183198; 57210740839; 57236123800; 55420263200; 59297330100 ⓘ drhussain@awkum.edu.pk;ijlee@knu.ac.kr; ⓘ JOURNAL OF HAZARDOUS MATERIALS ⓘ J HAZARD MATER ⓘ 0304-3894 1873-3336 424 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2022 13.6 3.5 2.15 2025-06-25 ⓘ 38 37 Pantoea conspicua; Aspergillus niger; Helianthus annuus L; Plant growth promotion; Cr+6 bio-remediation ⓘ HEXAVALENT CHROMIUM; GLUTATHIONE-REDUCTASE; ELECTROLYTE LEAKAGE; RAPID-DETERMINATION; METAL STRESS; GROWTH; PLANTS; FUNGI; WASTE; LIGNIFICATION ⓘ Aspergillus niger; Cr<sup>+6</sup> bio-remediation; Helianthus annuus L.; Pantoea conspicua; Plant growth promotion ⓘ Aspergillus niger; Biodegradation, Environmental; Chromates; Chromium; Pantoea; Soil Pollutants; Aspergillus niger; Helianthus annuus; Pantoea; Antioxidants; Aspergillus; Biotechnology; Chromates; Soil pollution; Soils; antioxidant; chromic acid; chromium; flavonoid; gibberellic acid; indoleacetic acid; peroxidase; phenol derivative; phytohormone; reactive oxygen metabolite; salicylic acid; chromium; Aspergillus niger; Bio remediations; Bioremediation potentials; Cr+6 bio-remediation; Helianthus annuus L; Host plants; Niger; Pantoea; Pantoea conspicua; Plant growth promotion; antioxidant; bioremediation; chromate; chromium; colonization; fungus; host plant; Article; Aspergillus niger; bacterial colonization; bacterial growth; bacterial strain; bioremediation; biosorption; biotransformation; comparative study; controlled study; endophytic fungus; fungal colonization; fungal strain; fungus growth; fungus hyphae; Helianthus annuus; hormone synthesis; nonhuman; nucleotide sequence; Pantoea; Pantoea conspicua; plant growth; plant microorganism interaction; plant root; plant stress; rhizosphere; Aspergillus niger; bioremediation; Pantoea; soil pollutant; Bioremediation ⓘ English 2022 2022-02-15 10.1016/j.jhazmat.2021.127314 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Construction and implementation of floating wetpark as effective constructed wetland for industrial textile wastewater treatment ⓘ Fimbristylis dichotoma, Ipomoea aquatica, Pluchea tomentosa and their co-plantation (consortium FIP) autonomously degrade Orange 3R. Consortium FIP showed 84% removal of Orange 3R within 48 h, which is a higher dye elimination rate than individual plant systems. Oxidoreductase enzymes like tyrosinase (76%), varatryal alcohol oxidase (85%), lignin peroxidase (150%), riboflavin reductase (151%), laccase (171%), NADH-DCIP reductase (11%) and azo reductase (241%) were expressed in consortia FIP during Orange 3R degradation. UV-vis spectroscopy, enzyme activities, HPTLC, FTIR and GC-MS confirmed mineralization of Orange 3R into its metabolites. Microscopic investigation of root tissue revealed the harsh effect of dye on root tissues. Toxicity assessment on the HepG2 cell line demonstrated the toxic nature of Orange 3R, which gets reduced after phyto-treatment with consortia FIP. Floating wetpark of consortia FIP was found more efficient for the treatment of industrial textile waste and accomplished 87%, 86%, 75%, 49% and 46% removal of COD, BOD, color, TSS and TDS of effluent. ⓘ Kadam, Suhas K.; Tamboli, Asif S.; Chandanshive, Vishal V.; Govindwar, Sanjay P.; Choo, Yeon-Sik; Pak, Jae Hong ⓘ Kyungpook Natl Univ, Sch Life Sci, Res Inst Dok Do & Ulleung Do Isl, Dept Biol, Daegu 41566, South Korea; Shivaji Univ, Dept Biochem, Kolhapur 416004, Maharashtra, India; Kyungpook Natl Univ, Sch Life Sci, Dept Biol, 80 Daehak Ro, Daegu 41566, South Korea ⓘ Tamboli, Asif/HJB-2803-2022; Kadam, Dr. Suhas/HNI-6437-2023; Kadam, Dr Suhas/HNI-6437-2023 ⓘ 57188723669; 56974034100; 56340221300; 6603868071; 26040458100; 7102232932 ⓘ suhas397@gmail.com;spgovindwar@rediffmail.com;Jhpak@knu.ac.kr; ⓘ JOURNAL OF HAZARDOUS MATERIALS ⓘ J HAZARD MATER ⓘ 0304-3894 1873-3336 424 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2022 13.6 3.5 0.72 2025-06-25 ⓘ 5 12 floating wetpark; phytoremediation; plant-plant consortia; textile effluent; toxicity analysis ⓘ ENHANCED DEGRADATION; TYPHA-ANGUSTIFOLIA; DYE MIXTURE; AZO-DYE; PHYTOREMEDIATION; EFFLUENT; DECOLORIZATION; LINN. ⓘ floating wetpark; phytoremediation; plant-plant consortia; textile effluent; toxicity analysis ⓘ Azo Compounds; Biodegradation, Environmental; Coloring Agents; Industrial Waste; Textile Industry; Textiles; Waste Water; Water Purification; Wetlands; Bioremediation; Cell culture; Citrus fruits; Effluent treatment; Effluents; Enzymes; Fourier transform infrared spectroscopy; Industrial water treatment; Metabolites; Sewage; Textile industry; Textiles; Tissue; Wastewater treatment; Wetlands; azo compound; coloring agent; Dichotoma; Elimination rate; Floating wetpark; Industrial textiles; Phytoremediation; Plant-plant consortium; Root tissues; Textile effluent; Textile wastewater treatment; Toxicity analyse; bioremediation; industrial waste; textile; textile industry; wastewater; water management; wetland; Toxicity ⓘ English 2022 2022-02-15 10.1016/j.jhazmat.2021.127710 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Effect of single and multilayered Ti3C2TX MXene as a catalyst and adsorbent on enhanced sonodegradation of diclofenac and verapamil ⓘ Single and multilayered Ti3C2TX MXene (referred to as SLM and MLM in this study, respectively) was applied as catalysts in the ultrasonic (US) process to treat selected pharmaceutical compounds including diclofenac and verapamil (VRP). Due to solid surface, elemental composition, and functional groups of Ti3C2TX MXene, the free OH center dot production was increased by 48.8% for the US treatment with SLM and 59.8% for the US treatment with MLM compared with the US-only treatment. Additionally, adsorption affected the performance during the US treatment in the presence of the catalyst. Thus, the US treatment in the presence of Ti3C2TX MXene had an enhanced performance not only because of increased oxidation but also because of adsorption, particularly between positively charged VRP and negatively charged Ti3C2TX MXene. Moreover, although the degradation of the performance was higher for SLM (85.1%) than for MLM (81.8%), by improving the dispersion and reducing the size via sonication, the US treatment in the presence of MLM showed the highest synergy effect. In other words, the US treatment in the presence of MLM showed higher performance than the simple sum of oxidation and adsorption. These findings confirm that the US treatment in the presence of MLM may be a promising technology to treat various pharmaceuticals as a more degradable, strongly reusable, and less toxic process. ⓘ Kim, Sewoon; Nam, Seong-Nam; Park, Chang Min; Jang, Min; Taheri-Qazvini, Nadar; Yoon, Yeomin ⓘ Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Korea Army Acamemy Yeong Cheon, Dept Civil Engn, 495 Hogook Ro, Yeong Cheon 38900, Gyeongbuk, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kwangwoon Univ, Dept Environm Engn, 20 Kwangwoon Ro, Seoul 01897, South Korea; Univ South Carolina, Dept Chem Engn, Columbia, SC 29208 USA; Univ South Carolina, Biomed Engn Program, Columbia, SC 29208 USA ⓘ Nam, Seong-Nam/ABT-9415-2022; Yoon, Yeomin/KDP-2253-2024; Jang, Min/J-2230-2012; Park, Chang Min/CAA-8506-2022; Jang, Min/M-6690-2018 ⓘ 57201422323; 57226757907; 57209588953; 36762550700; 36609373800; 7402126688 ⓘ yoony@cec.sc.edu; ⓘ JOURNAL OF HAZARDOUS MATERIALS ⓘ J HAZARD MATER ⓘ 0304-3894 1873-3336 426 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2022 13.6 3.5 1.55 2025-06-25 ⓘ 22 26 Ti3C2TX MXene; Pharmaceuticals; Ultrasonics; Catalyst; Adsorption ⓘ SONOCATALYTIC DEGRADATION; SONOCHEMICAL DEGRADATION; ULTRASONIC DEGRADATION; ACTIVATED CARBON; EMERGING CONCERN; WASTE-WATER; REMOVAL; CONTAMINANTS; ACETAMINOPHEN; IRRADIATION ⓘ Adsorption; Catalyst; Pharmaceuticals; Ti<sub>3</sub>C<sub>2</sub>T<sub>X</sub> MXene; Ultrasonics ⓘ Adsorption; Diclofenac; Oxidation-Reduction; Titanium; Verapamil; United States; Catalysts; Titanium compounds; Ultrasonics; adsorbent; carbon; diclofenac; hydrogen peroxide; titanium; verapamil; verapamil; Diclofenac; Multi-layered; Performance; Pharmaceutical compounds; Sonodegradations; Ti3C2TX mxene; Ultrasonic process; Ultrasonic treatments; Verapamil; ]+ catalyst; adsorption; biodegradation; catalyst; dispersion; drug; oxidation; ultrasonics; adsorption; Article; atomic force microscopy; catalyst; chemical composition; controlled study; crystal structure; degradation; dispersion; first order rate constant; human; infrared spectroscopy; mineralization; oxidation; pH; photon correlation spectroscopy; physical chemistry; rate constant; reaction time; temperature; transmission electron microscopy; ultrasound; water quality; water solubility; oxidation reduction reaction; Adsorption ⓘ English 2022 2022-03-15 10.1016/j.jhazmat.2021.128120 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Insight into the role of charge carrier mediation zone for singlet oxygen production over rod-shape graphitic carbon nitride: Batch and continuous-flow reactor ⓘ As a new approach of creating the photo-exited electron (e(-)) and hole (h(+)) mediation zone for highly selective singlet oxygen (O-1(2)) production, the rod-type graphitic carbon nitride (NCN) has been synthesized from the nitric acid-modified melamine followed by the calcination. The NCN exhibited a higher surface area and surface oxygen adsorption ability than bulk graphitic carbon nitride (BCN). The increment of C=O and NHx groups on NCN corresponded to e(-) and h(+) mediation groups, respectively, resulting in higher production of O-1(2) than BCN. Moreover, those mediation groups on NCN result in higher recombination efficiency and longer e(-) decay time. As a result, the optimized NCN-0.5 (derived from 0.5 M of nitric acid-modified melamine) displayed 5.8 times higher kinetic rate constant of atrazine (ATZ) removal under UVA-LED irradiation compared to BCN. This study also evaluated the ATZ degradation pathways and toxicity effect of by-products. In addition, continuous flow experiments using NCN-0.5 showed superior ATZ removal performance with a hybrid concept between a slurry photocatalysis and a continuous stirred tank reactor system using actual effluent obtained from a wastewater treatment plant. Thus, this work provides an insight into the strategy for highly selective O-1(2) production and the potential for water purification application. ⓘ Kim, Hyeseong; Choong, Choe Earn; Han, Ihn; Park, Chang Min; Nah, In Wook; Kim, Jung Rae; Jeon, Byong-Hun; Yoon, Yeomin; Jang, Min ⓘ Kwangwoon Univ, Dept Environm Engn, 20 Kwangwoon Ro, Seoul 01897, South Korea; Kwangwoon Univ, Plasma Biosci Res Ctr, 26 Kwangwoon Ro, Seoul 01899, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Inst Sci & Technol, Ctr Energy Convergence, Seoul 02792, South Korea; Pusan Natl Univ, Sch Chem Engn, 63 Busandeahak Ro, Busan 46241, South Korea; Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA ⓘ Choong, Choe Earn/J-3005-2016; Park, Chang Min/CAA-8506-2022; Kim, Jung/N-8018-2013; Jang, Min/M-6690-2018; Yoon, Yeomin/KDP-2253-2024; Han, Ihn/ABH-6275-2020; Jeon, Byong-Hun/AAF-4352-2020; Jang, Min/J-2230-2012 ⓘ 57221054537; 57200944393; 36188210400; 57209588953; 6505864566; 8545413900; 57653536800; 7402126688; 36762550700 ⓘ cce@live.com;minjang@kw.ac.kr;cce_@live.com; ⓘ JOURNAL OF HAZARDOUS MATERIALS ⓘ J HAZARD MATER ⓘ 0304-3894 1873-3336 424 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2022 13.6 3.5 1.91 2025-06-25 ⓘ 31 32 Photocatalysis; Singlet oxygen; Graphitic carbon nitride; Continuous stirred tank reactor ⓘ ENHANCED PHOTOCATALYTIC DEGRADATION; PERSISTENT ORGANIC POLLUTANTS; HYDROGEN-PRODUCTION; ULTRATHIN G-C3N4; GENERATION; OXIDATION; WATER; NITROGEN; NANOSHEETS; MECHANISM ⓘ Continuous stirred tank reactor; Graphitic carbon nitride; Photocatalysis; Singlet oxygen ⓘ Carbon nitride; Chemical reactors; Effluent treatment; Effluents; Nitric acid; Oxygen; Photocatalysis; Rate constants; Supercritical fluids; Tanks (containers); Wastewater treatment; acetic acid; atrazine; carbon; carbon nitride; deionized water; dissolved oxygen; hydroxyl group; melamine; nitrate; nitric acid; nitrogen; polyethersulfone; singlet oxygen; triazine; unclassified drug; Atrazine removal; Batch flows; Carrier mediation; Continuous flow reactors; Continuous stirred tank reactor; Graphitic carbon nitrides; New approaches; Singlet oxygen; Singlet oxygen production; Synthesised; adsorption; atrazine; catalysis; inorganic compound; oxygen; photodegradation; pollutant removal; adsorption; animal experiment; Article; contact angle; controlled study; Daphnia magna; degradation; electric conductivity; electrospray; energy consumption; field emission scanning electron microscopy; Fourier transform infrared spectroscopy; furnace; impedance spectroscopy; liquid chromatography-mass spectrometry; multiple reaction monitoring; nonhuman; oxidation reduction potential; photocatalysis; photoluminescence; Pimephales promelas; pore size distribution; surface area; waste water treatment plant; water management; X ray diffraction; Gas adsorption ⓘ English 2022 2022-02-15 10.1016/j.jhazmat.2021.127652 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Mangrove's rhizospheric engineering with bacterial inoculation improve degradation of diesel contamination ⓘ Mangroves (Avicennia marina) growing in intertidal areas are often exposed to diesel spills, adversely damaging the ecosystem. Herein, we showed for the first time that mangrove seedlings' associations with bacteria could reprogram host-growth, physiology, and ability to degrade diesel. We found four bacterial strains [Sphingomonas sp.-LK11, Rhodococcus corynebacterioides-NZ1, Bacillus subtilis-EP1 Bacillus safensis-SH10] exhibiting significant growth during diesel degradation (2% and 5%, v/v) and higher expression of alkane monooxygenase compared to control. This is in synergy with reduced long-chain n-alkanes (C24-C30) during microbe-diesel interactions in the bioreactor. Among individual strains, SH10 exhibited significantly higher potential to improve mangrove seedling's morphology, anatomy and growth during diesel treatment in rhizosphere compared to control. This was also evidenced by reduced activities and gene expression of antioxidant enzymes (catalases, peroxidases, ascorbic peroxidases, superoxide dismutases and polyphenol peroxidases) and lipid peroxidation during microbe diesel interactions. Interestingly, we noticed significantly higher soil-enzyme activities (phosphatases and glucosidases) and essential metabolites in seedling's rhizosphere after bacteria and diesel treatments. Degradation of longer n-alkane chains in the rhizosphere also revealed a potential pathway that benefits mangroves by bacterial strains during diesel contaminations. Current results support microbes' application to rhizoengineer plant growth, responses, and phytoextraction abilities in environments contaminated with diesel spills.
