| ○ | ○ | Article | Effects of B and Ti addition and heat treatment temperature on graphitization behavior of Fe-0.55C-2.3Si steel | We determined the effects of alloying elements and heat treatment temperature on the graphitization behavior of a medium-carbon high-silicon steel (Fe-0.55C-2.3Si, wt%). Trace amounts ( B-bearing steel > base steel, which is attributed to the numerous grain boundaries in the Ti-bearing steel and presence of BN particles in the B-bearing steel because the grain boundaries and BN particles act as major graphite nucleation sites. A higher abundance of nucleation sites for graphitization in the initial microstructure leads to higher graphite density but reduced average graphite size. For all three steels, higher heat treatment temperature promoted both cementite decomposition and graphite formation by accelerated carbon diffusion, which reduced the graphitization completion time, decreased the graphite number density, and increased the graphite size. Fine and uniformly distributed graphite forms within a short time (1 h) in the Ti-bearing steel treated at 750 degrees C, which significantly decreased its strength and improved its ductility.

| ○ | ○ | Article | Enhanced thermomechanical property of a self-healing polymer via self-assembly of a reversibly cross-linkable block copolymer | We report the preparation and thermomechanical properties of hetero-nanostructured self-healing polymers (HSPs) bearing a hindered urea bond (HUB) by varying the content of a self-healable block copolymer (BCP). The micellar morphology of the BCP blend in a matrix polymer was studied using transmission electron microscopy and grazing-incidence small-angle X-ray scattering with various organic solvent types and BCP contents. The self-healing efficiency of the HSPs was obtained from single-scratch tests through optical microscopy and atomic force microscopy. To confirm self-healing at the molecular level, the mechanical properties of the cross-cut and healed HSPs were also analyzed using a universal testing machine. Thermomechanical properties associated with HUB were measured by dynamic mechanical analysis and temperature-oscillating rheometry. The results showed that blending the BCP improved the toughness, the hardness, and the modulus up to 21.7, 25.3, and 24.8%, respectively. Moreover, at high temperatures, the temperature range of the rubbery plateau was greatly widened without a noticeable decrease in the self-healing capability. | Lee, Hyang Moo; Perumal, Suguna; Kim, Gi Young; Kim, Jin Chul; Kim, Young-Ryul; Kim, Minsoo P.; Ko, Hyunhyup; Rho, Yecheol; Cheong, In Woo | Kyungpook Natl Univ, Dept Appl Chem, Daehak Ro 80, Daegu 41566, South Korea; Korea Res Inst Chem Technol, Res Ctr Green Fine Chem, Ulsan 44412, South Korea; Ulsan Natl Inst Sci & Technol, Sch Energy & Chem Engn, Ulsan 44919, South Korea; Korea Res Inst Chem Technol, Chem Anal Ctr, Daejeon 34114, South Korea | ; perumal, suguna/N-9075-2017; Kim, Kyoung-Sook/A-7768-2017 | 55598631800; 56673798900; 57210997221; 56805502600; 57218459894; 55153668300; 54970606500; 24076715300; 7006733373 | inwoo@knu.ac.kr; | POLYMER CHEMISTRY | POLYM CHEM-UK | 1759-9954 | 1759-9962 | 11 | 22 | SCIE | POLYMER SCIENCE | 2020 | 5.582 | 10.6 | 0.86 | 2025-06-25 | 18 | 16 | Atomic force microscopy; Blending; Block copolymers; High resolution transmission electron microscopy; Self assembly; Urea; X ray scattering; Grazing incidence small-angle X-ray scattering; Molecular levels; Polymer Chemistry; Self-healing capabilities; Self-healing polymers; Temperature range; Thermomechanical properties; Universal testing machines; Self-healing materials | English | 2020 | 2020-06-14 | 10.1039/d0py00310g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | ○ | Article | General method for the production of hydrogel droplets from uniformly sized smart shell membranes | A smart solid-state liquid crystal (LCsolid) shell membrane template prepared by a microfluidic method with a reactive mesogen mixture of RMM727 (from Merck) doped with a nematic liquid crystal of 4 '-pentyl-4-biphenylcarbonitrile (5CB) as a porogen was used for a facile and general method to produce uniformly sized hydrogel droplets. The reactive hydrogel monomers were incorporated into the core of the LC(solid)shell through the shell pores by immersing the LC(solid)shells in the reactive hydrogel monomer mixture. Subsequently, the hydrogel monomer mixture outside the LC(solid)shells was replaced with a non-reactive medium that can close the pores because of its poor solvent nature with respect to the LC(solid)shell, confining the hydrogel monomer mixture at the core during UV curing. After UV curing, uniformly sized hydrogel droplets were hatched out from the LC(solid)shell when the hydrogel droplet-containing LC(solid)shells were put into a solvent, causing the hydrogel droplets to swell more than the LC(solid)shells. The hydrogel droplets were separated from the broken LC(solid)shell using two immiscible solvents, each of which contained hydrogel droplets and broken LC(solid)shells. The hydrogel droplets generated based on the LC(solid)shell template were poly(acrylic acid) (PAA), poly(N-isopropylacrylamide) (PNIPAM), and P(AA-co-NIPAM), which denote the pH-, temperature-, and dual (both pH and temperature)-responsive properties. In particular, the molar ratio of the P(AA-co-NIPAM) hydrogel droplet composition could be easily altered by changing the mixing ratio of the AA/NIPAM monomer mixture without tuning the processing conditions for droplet production, which is usually needed when using microfluidic devices. The proposed method can be used to obtain uniformly sized hydrogel droplets without using any instrument (e.g., microfluidic devices) or stabilizing material (e.g., surfactants) at any convenient time. | Gwon, So-Jeong; Park, Soo-Young | Kyungpook Natl Univ, Polymer Nano Mat Lab, Sch Appl Chem Engn, Daegu 41564, South Korea | park, soo-young/N-3170-2017 | 57219337908; 57194041850 | psy@knu.ac.kr; | POLYMER CHEMISTRY | POLYM CHEM-UK | 1759-9954 | 1759-9962 | 11 | 34 | SCIE | POLYMER SCIENCE | 2020 | 5.582 | 10.6 | 0.29 | 2025-06-25 | 4 | 4 | PH; MICROFLUIDICS; NANOPARTICLES | Acrylic monomers; Amides; Ascorbic acid; Curing; Drops; Fluidic devices; Microfluidics; Mixtures; Molar ratio; Nematic liquid crystals; Shells (structures); Solvents; Droplet production; Immiscible solvents; Micro-fluidic devices; Microfluidic method; Poly(N-isopropyl acrylamide) (pNIPAM); Polyacrylic acids; Processing condition; Stabilizing materials; Hydrogels | English | 2020 | 2020-09-14 | 10.1039/d0py00679c | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Bifurcation phenomena of natural convection in horizontal annulus under self-induced circular magnetic fields | Purpose In general, the bifurcation phenomenon of the natural convection has largely been studied. But the bifurcation of natural convection under magnetic conditions has not been studied as per the authors' knowledge. This paper aims to investigate the changes in bifurcation phenomenon by the self-induced circular magnetic field. Design/methodology/approach The authors numerically solved the natural convection in an annulus. The SIMPLE algorithm was adopted for pressure-momenturm coupling. The Boussinesq approximation was used for numerical modeling of natural convection. Finally, the Lorentz force effect by the magnetic field was considered through the source terms in the momentum conservation equation. Findings It was determined that the heat-transfer rate changes by 17% owing to the applied magnetic effect, and the range of the Rayleigh number for flow bifurcation is changed by the magnetic effect. Moreover, under the strong magnetic condition, the flow bifurcation continues even at very high Ra. Previously, flow bifurcation has been understood as a flow instability phenomena, and the Lorentz force was regarded as a flow-damping effect; however, in this study, it was found that the magnetic field can boost the flow instability and induce flow bifurcation even in the Rayleigh number region where the bifurcation does not appear. Originality/value This paper is dealing with the bifurcation phenomenon in MHD natural convection problems. In the past, the electromagnetic forces were regarded as always acting to damp out the existing flows; herewith, the authors first investigated that the magnetic effect can boost the bifurcation of a kind of flow instability phenomenon. | Oh, Jin Ho; Park, Il Seouk | Kyungpook Natl Univ, Daegu, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea | 57200224289; 50262800000 | einstein@knu.ac.kr; | INTERNATIONAL JOURNAL OF NUMERICAL METHODS FOR HEAT & FLUID FLOW | INT J NUMER METHOD H | 0961-5539 | 1758-6585 | 30 | 4 | SCIE | MATHEMATICS, INTERDISCIPLINARY APPLICATIONS;MECHANICS;THERMODYNAMICS | 2020 | 4.17 | 10.7 | 0.08 | 2025-06-25 | 2 | 3 | Bifurcation; Natural convection; Magnetohydrodynamics | NUMERICAL-SOLUTION; FLOW PATTERNS; ENCLOSURE; DIRECTION | Bifurcation; Magnetohydrodynamics; Natural convection | Bifurcation (mathematics); Lorentz force; Magnetohydrodynamics; Bifurcation; Bifurcation phenomena; Condition; Design/methodology/approach; Flow bifurcations; Flow instabilities; Horizontal annulus; Magnetic effects; Magnetic-field; Rayleigh number; Natural convection | English | 2020 | 2020 | 10.1108/hff-11-2018-0645 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Review | A review on MXene-based nanomaterials as adsorbents in aqueous solution | Environmental pollution has intensified and accelerated due to a steady increase in the number of industries, and finding methods to remove hazardous contaminants, which can be typically divided into inorganic and organic compounds, have become inevitable. One of the widely used water treatment technologies is adsorption and various kinds of adsorbents for the removal of inorganic and organic contaminants from water have been discovered. Recently, MXene, as an emerging nanomaterial, has gained rapid attention owing to its unique characteristics and various applicability. Particularly, in the area of adsorptive application, MXene and MXene-based adsorbents have shown great potential in a large number of studies. In this regard, a comprehensive understanding of the adsorptive behavior of MXene-based nanomaterials is necessary in order to explain how they remove inorganic and organic contaminants in water. Adsorption by MXene-based adsorbents tends to be highly influenced by not only the physicochemical properties of these adsorbents but also water quality, such as pH value, temperature, background ion, and natural organic matter. Therefore, in this review paper, the effect of various water quality on the adsorption of inorganic and organic contaminants by various types of MXene and MXene-based adsorbents is explored. Furthermore, this review also covers general trends in the synthesis of MXene and regeneration of MXene-based adsorbents in order to assess their stability. (C) 2020 Elsevier Ltd.

| ○ | ○ | Article | Acute toxicities of fluorene, fluorene-1-carboxylic acid, and fluorene-9-carboxylic acid on zebrafish embryos (Danio rerio): Molecular mechanisms of developmental toxicities of fluorene-1-carboxylic acid | In this study, fluorene (FL), FL-1-carboxylic acid (FC-1), and FL-9-carboxylic acid (FC-9) were investigated to understand their acute toxicity by measuring inhibitory effects on hatching rates and developmental processes of zebrafish embryos (Danio rerio). For exposure concentrations up to 3000 mu g/L, FC-1 alone showed acute toxicity at 1458 ng/L for LC50 value. FC-1 caused yolk sac and spinal deformities, and pericardial edema. Molecular studies were undertaken to understand FC-1 toxicity examining 61 genes after exposure to 5 mu M (equivalent to LC20 value of FC-1) in embryos. In the FC-1-treated embryos, the expression of the cyp7a1 gene, involved in bile acid biosynthesis, was dramatically decreased, while the expression of the Il-1 beta gene involved in inflammation was remarkably increased. In addition to these findings, in FC-1-treated embryos, the expression of nppa gene related to the differentiation of the myocardium was 3-fold increased. On the other hand, cyp1a, cyp3a, ugt1a1, abcc4, mdr1, and sult1st1 responsible for detoxification of xenobiotics were upregulated in FC-9-treated embryos. Taken together, carboxylation on carbon 1 of FL increased acute toxicity in zebrafish embryos, and its toxicity might be related to morphological changes with modification of normal biological functions and lowered defense ability.

| ○ | ○ | Review | Applications of metal-organic framework based membranes in water purification: A review | Metal-organic frameworks (MOFs) have attracted a great deal of attention due to their flexibility and various potential applications. MOF-based membranes have been widely applied in forward-osmosis (FO), reverse-osmosis (RO), nanofiltration (NF), and ultrafiltration (UF) processes. While a few recent studies have reviewed the applications of MOF-based membranes in water purification, a systematic understanding is still necessary to evaluate the transport mechanisms of various compounds by different MOF-based membranes under various operating and water-quality conditions. Here, we present a comprehensive literature review of recent findings and suggest future research trends by identifying insufficiencies of current knowledge, focusing on the performance of MOF-based membranes in water purification, as the transport of inorganic and organic compounds by MOF-based membranes is highly influenced by the different properties of compounds in addition to waterchemistry conditions and membrane properties. This study focused on several main parameters such as methods for synthesis of MOF-based membranes, membrane properties, and the physicochemical properties of various compounds, which affect the transport of compounds during MOF-based FO/RO/NF/UF membrane filtration. In addition, we provide the continuing challenges and areas of future study in this field. | Jun, Byung-Moon; Al-Hamadani, Yasir A.

| ○ | ○ | Article | Design and synthesis of biopolymer-derived porous graphitic carbon covered iron-organic frameworks for depollution of arsenic from waters | A series of alginate-derived porous graphitic carbon (PGC) wrapped iron-based organic frameworks (Fe-MIL-88B) composites were synthesized and checked their ability for the removal of arsenite (As(III)) and arsenate (As(V)) from water. Various amounts of PGC (5, 10, 20, and 50 wt/wt %) were utilized as a wrapping material for the development of composites with Fe-MIL-88B@PGCk% and optimized for As(III)/As(V) adsorption. The chemical functionalities, structure, morphology, porous properties and bonding nature of the adsorbents were analyzed using FTIR, PXRD, SEM, BET, and XPS, respectively. Fe-MIL-88B@PGC20% composite was explored to have maximum removal efficiency and fastest adsorption kinetics for As(III)/As(V), of all Fe-MIL-88B@PGCx% composites and pristine Fe-MIL-88B studied here. The developed adsorbents are highly pH dependent and selective in common co-existing anions except for F- , PO43- and humic acid. The Langmuir isotherm studies of As(III) and As(V) adsorption suggest maximum adsorption capacities of 1.6853 and 2.2636 mmol/g, at pH of 3.0 and 9.2, respectively. The XPS analysis of As(III)-sorbed Fe-MIL-88B@PGC20% composite reveals that a portion of As(III) has been oxidized into As(V) during the adsorption process.

| ○ | ○ | Article | Effect of citric acid and vermi-wash on growth and metal accumulation of Sorghum bicolor cultivated in lead and nickel contaminated soil | The aim of the present study is to assess the influence of vermi-wash (VW) and citric acid (CA) on Sorghum bicolor growth and phytoaccumulation of lead (Pb) and nickel (Ni) contaminated soil. The biomass of the S. bicolor has been enhanced by the addition of VW (24 and 26%) and CA (11 and 9%) in Pb and Ni contaminated soil, respectively. The VW treatment showed enhanced shoot and root lengths and chlorophyll concentrations compared to CA. The shoot anatomic structure showed an accumulation of Pb and Ni were positively impacted by the amendment of VW and CA. In addition, VW treatment showed enhanced antioxidant enzymes activity (140, 125 and 152 U/mg of CAT, SOD and POD). Further, the plants grown in Pb contaminated soil treated with VW showed enhanced Rubisco activity of 1.49 U/ml, whereas, CA treatment showed 1.23 U/ml of Rubisco. It has been observed that the VW showed as a potential chelator as well as plant beneficial formulation for the enhanced phyto-remediation of Pb and Ni. (C) 2019 Elsevier Ltd.

| ○ | ○ | Article | Enhanced electrochemical degradation of 2,4-dichlorophenol with the assist of hydrochar | Effective treatment of 2,4-dichlorophenol (2,4-DCP) in wastewater is essential, as it could pose great threat to the environment. A hydrothermal biochar (hydrochar) was used to assist the electrochemical oxidation treatment of 2,4-DCP. The removal of 2,4-DCP using hydrochar in anode and cathode area with and without proton exchange membrane (PEM) under 3-9 V of electrolysis was investigated. Enhanced 2,4-DCP degradation in the anode area was achieved compared with the adsorption or electrolysis alone. The highest 2,4-DCP removal (similar to 76%) was obtained using the hydrochar in the anode area with PEM under 9 V. The mechanism for the 2,4-DCP removal during the electrolysis included adsorption by hydrochar and electrochemical degradation by the reactive oxygen species (ROS) generated by the electrode as well as the persistent free radicals (PFR) on hydrochar. The center dot OH produced from anode was the predominant ROS contributing to the 2,4-DCP degradation under 9 V of electrolysis. (C) 2020 Elsevier Ltd.

| ○ | ○ | Article | Enhanced sonophotocatalytic degradation of bisphenol A using bimetal sulfide-intercalated MXenes, 2D/2D nanocomposite | A novel 2D Ti3C2Tx MXene (MX) co-catalyst and NixMg4-xS4 (NMS) nanocomposite (NMS@MX ) was simply prepared through a hydrothermal method and utilized as a sonophotocatalyst for the degradation of bisphenol A (BPA). Because the remediation of wastewater containing endocrine-disrupting compounds is an important issue in environmental fields, BPA was selected as the main organic pollutant to clarify the sonophotocatalytic activity of NMS@MX in this study. We confirmed the successful synthesis of NMS@MX through Fourier-transform infrared spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy analyses. The mineralization of BPA via sonophotocatalysis with NMS@MX was much faster and more efficient than by applying photolysis and sonolysis, separately. The NMS@MX sonophotocatalyst showed high sonophotocatalytic activity based on similar to 92% degradation of BPA within 60 min using both visible light and ultrasonication. This outcome could have resulted from the mitigation of the photo-corrosion of metal sulfides through heterojunction structures combined with the highly conducive MX co-catalyst. Furthermore, NMS@MX showed excellent sonophotostability over four consecutive cycles for the degradation of BPA with negligible loss of sonophotocatalytic activity. Finally, we proposed the sonophotocatalytic degradation pathway of BPA in the Sono/Vis/MNS@MX system (Sono = sonolysis; Vis = photolysis). | Vigneshwaran, Sivakumar; Jun, Byung-Moon; Prabhu, Subbaiah Muthu; Elanchezhiyan, S.

| ○ | ○ | Article | Ethylene glycol-induced metal alkoxides via phase-transfer catalyst as multi-talented adsorbents for boosted adsorption performance of toxic anions/oxyanions from waters | An outstanding multi-talented complex material for the removal of several toxic anions is of greater interest than that used for single-pollutant adsorption. Here, we report the synthesis of highly stable lanthanum- and zirconium-alkoxides (La-Alk and Zr-Alk) using a strong-field ligand and the electron-donating nature of ethylene glycol (EG) through a phase-transfer catalyst, dodecyltrimethylammonium bromide (DTAB), was employed to boost the adsorption densities of various toxic anions, such as arsenate (AsO43-), arsenite (AsO33-), dichromate (Cr2O72-), phosphate (PO43-), fluoride (F-), and selenate (SeO42-) in water by the application of the basic concept of the HSAB principle. The adsorbents had been characterized before and after adsorption of highly concentrated toxic anions (each of 1 mM) using XPS, PXRD, FTIR, BET, and SEM, and the possible adsorption mechanism was elucidated. The coordination of EG over La(OH)(3) and ZrO2 was confirmed by the FTIR and PXRD patterns. The SEM images of La-Alk revealed a regular flower-like structure, whereas the structure of Zr-Alk was spherical, which differs from their precursors or pristine forms. The selectivity and stability of the materials were confirmed by a study on the coexisting anions in a binary mixture solution and reusability studies by repeated use, respectively. We found that La-Alk was more selective for the adsorption of arsenate, dichromate, phosphate, fluoride, and selenate, whereas Zr-Alk was highly selective for arsenite at a concentration of 1 mM. We are certain that the multifunctional La- and Zr-Alk nanocomplexes developed in this study will be useful for practical applications in water and wastewater streams. | Prabhu, Subbaiah Muthu; Pandi, Kalimuthu; Elanchezhiyan, S.

| ○ | ○ | Article | Mechanism of simultaneous removal of aluminum and fluoride from aqueous solution by La/Mg/Si-activated carbon | La/Mg/Si-activated carbon derived from palm shell has been a suitable material for removal of aluminum and fluoride from aqueous solution. In the study, the mechanism of simultaneous removal of aluminum and fluoride by La/Mg/Si-activated carbon (La/Mg/Si-AC) was investigated to understand its high efficiency. It was found that the removal of aluminum and fluoride by La/Mg/Si-AC was favored at lower pH compared to the point of zero charge of La/Mg/Si-AC and high temperature. Adsorption capacity of Al(OH)(4)(-) was about 10 times higher than that of F- due to the strong binding affinity of Al(OH)(4)(-) on protonated surface and competition between F- and OH- toward charged adsorption site. Kinetics results showed that the aluminum and fluoride adsorption were explained using the pseudo-second-order kinetic model and intra-particle diffusion model. Adsorption process of Al(OH)(4)(-) and F- was driven by the potential rate-limiting step involved in mass transport process occurred on the boundary diffusion layer of porous adsorbent surface. Electrostatic interaction between protonated surface of La/Mg/Si-AC and negatively charged ions (i.e., Al(OH)(4)(-) and F-) as well as ion-exchange between hydroxide and ionic metal species were important mechanisms in the process of aluminum and fluoride adsorption. Driving forces for adsorption of individual Al(OH)(4)(-) and F- were not entirely different. Identifying the dominant mechanism will be helpful in understanding the adsorption process and developing new adsorbent.
