Herein, a conjoined-network induced hydrogel was prepared through the in-situ free radical copolymerization of acrylamide (AM), Acrylic acid (AA) and N,N′-methylenebis(acrylamide) (MBA) in the presence of nano-cellulose (CNF/ACNF), and the coordination effect between aluminium ion and carboxyl. The results showed that a small amount of nano-cellulose (0.2 %) increased the compressive strength of the hydrogel by 7 times. The presence of nano-cellulose endowed the hydrogel with excellent thermal stability and high shearing elasticity, at the same time, could effectively reduced the swelling rate that hindered its disintegration in practical application. The evaluation of sand-pack plugging suggested that the double cross-linked nano-cellulose hydrogel presented a significant capacity for efficient water plugging, where the breakthrough pressure gradient was as high as 23.73 MPa, the plugging rate reached 99.9%, and the maximum residual resistance factor was 3902.06. This work provided a novel design of hydrogel with high compressive strength and satisfactory stability for water shutoff and conformance control in heterogeneous oil reservoirs.

    查看更多>>摘要：? 2022A practical and smart micelle system with pH, light and temperature responses, prepared using the cationic surfactant 3-hexadecyloxy-2-hydroxypropyl trimethyl ammonium bromide and 4-(phenylazo)-benzoic acid (ACA) (in its salt form), was developed as a highly promising fluid for applications in different fields. With increasing the trans-ACA concentration, η0 of the solution increases first and decreases subsequently, and the maximum was at 17 mM, the micellar structure transform from spherical to wormlike micelles, and then to rod morphology. The solution viscosity could be reversibly regulated at pH 4–12 due to the transition of aggregate morphology of self-assembling structure. UV/vis irradiation resulted in a trans to cis photoisomerization of the ACA molecule, and induced the conversion of corresponding wormlike structures into the rodlike micelles. With temperature increase the η0 of solution peaks at 28.6 °C and it doesn't follow an Arrhenius law, micellar contour length profile also varies between wormlike and rodlike. The regulatory mechanism of the micellar solution under the three stimuli is discussed based on the obtained data. This novel smart system may provide a new theoretical basis for future applications, opening a new avenue for synthesizing multifunctional aggregates to adapt to various environmental changes.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryPolyurethane foam (PUF) is formed by reacting sugar, propolis, and polyisocyanate, and then blowing with CO2, formed by reacting polyisocyanate with water. An optimum foaming rate of 1440% was found for 15 wt.% of sugar and 20 wt.% of propolis, and the synthesis and cell structure of polyurethane were analyzed by scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Under the optimized conditions, the apparent density and thermal conductivity of the PUF-containing propolis were 0.04 – 0.147 g/mL and 0.028 – 0.029 W/(mK), respectively. The bacterial reduction rate was 92.7% in the PUF containing 20 wt.% propolis. PUF can be broken down by enzymatic reactions in water using invertase. The degradation reaction of invertase was kinetically analyzed. This study showed that eco-friendly polymers can be synthesized using sugar and propolis and decomposed through antibacterial activity and enzymatic green recycling.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryIn this research, a contra-diffusion cell, which is an effective instrument for growing inorganic layers on porous substrates, was applied to prepare a thin layer of zeolitic imidazole framework-8 (ZIF-8) on polyvinylidene fluoride (PVDF) ultrafiltration membranes. With using of methanol as a solvent, a thin layer of ZIF-8 was fabricated resulted in a flexible inorganic coated organic membrane. The ZIF-8 nanoparticles were formed as a resistant layer on the outer surface and inner pores of PVDF support and its effect on permeability, flux recovery ratio (FRR) and treatment of colored wastewater was investigated. Manufacturing parameters such as the reaction time between Zn2+ ions and imidazole ligands (16, 24 and 36 h) and concentration of PVDF in the casting solution of the support membranes (18, 20 and 22 wt%) were considered. The SEM images showed the well-growing of uniform and a thin layer of ZIF-8. The membrane performance tests revealed that ZIF-8 decorated membranes have higher pure water flux, BSA protein rejection and FRR related to the uncoated PVDF membrane. The fabricated membranes indicated high removal efficiency in three different MW dyes (Rhodamine B, Reactive Green 19 and Direct Black 38), with 75, 85 and 98% rejection, respectively.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryAs a key member of benzoylurea insecticides, lufenuron exhibits a strong potential for bioaccumulation in ecosystems. Here, we report the synthesis of a molecularly imprinted polymer (MIP) and its application for selective extraction of lufenuron from agricultural runoff samples. The morphology and thermal stability of the prepared MIP was characterized by SEM and TGA, respectively. The experimental conditions for lufenuron detection were optimized through batch binding assay and response surface methodology (RSM). The MIP showcased a two-fold enhancement in binding capacity of lufenuron (74 mg g?1) relative to non-imprinted polymer (36 mg g?1), when measured through batch binding assay. Using a RSM based on central composite design, the qe value was predicted as 73.6 mg g?1 under optimal experimental conditions (e.g., pH 8). Furthermore, the percentage recovery of lufenuron was estimated as 98.8 ± 1.8% (n = 9). The adsorption kinetics of the MIP followed the pseudo-first-order model with χ2 value of 0.004 (correlation coefficient of 0.99). The limit of detection for lufenuron using MIP-based method was 3 × 10?6 μg mL?1. There was no significant decrease in the performance of MIP against lufenuron over five successive cycles.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryIn this work, chitosan and poly(vinylpyrrolidone) based (3-mercaptopropyl)trimethoxysilane (MPTMS) crosslinked hydrogels were prepared for application in drug delivery systems. The swelling behavior in distilled water started to increase until the crosslinker concentration reached the optimum level. The most significant swelling characteristic is noticed in buffer solutions, with higher swelling in an acidic medium and lower swelling in a neutral or basic medium. Morphological studies showed the porous and network structure of specimens, which determines the swelling and release characteristics. Hydrogels manifested antimicrobial characteristics against Listeria monocytogenes (L. monocytogenes) and Salmonella typhimurium (S. typhimurium) bacterial strains. The cell viability against RAW 264.7 cell lines was >90%, and at higher concentrations, the hydrogels showed anti-cancer efficacy against stomach cancerous AGS cell lines. In vitro drug release analysis of benzocaine in phosphate buffer saline (pH 7.4) and simulated intestinal fluid (pH 6.8) showed >90% release within 2 h. These stimuli-responsive hydrogels show enhanced antimicrobial characteristics, biocompatibility, and anti-cancer efficacy, as well as capability of drug release in a controlled manner, which makes them remarkable candidates for use in sustainable drug delivery systems.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryIn this study, functional montelukast (MTL) imprinted biomaterials were prepared using inulin (INL), polyvinyl alcohol (PVA), MTL, sunset yellow FCF (SY) as a light stabilizer, plasticizers, and press needle (PN). INL-based biomaterials were synthesized with a casting method followed by heat curing. MTL and biomaterials were characterized by FE-SEM, FT-IR, and 1H NMR. In addition, MTL release properties on MTL imprinted biomaterials were examined at pH 5.5 at various temperatures. Results showed that MTL release (%) of SY added biomaterials was increased by 1.97 times compared to those of MTL imprinted biomaterials without the addition of SY. This might be because SY, a light stabilizer, could inhibit the degradation of MTL by light. Results of MTL release using artificial skin verified that MTL was released sustainably for 12 h. We further confirmed that MTL release at pH 5.5 at various temperatures followed the pseudo-Fickian diffusion mechanism, whereas MTL release using artificial skin followed the non-Fickian diffusion mechanism.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryA novel ZrO2-(aniline (AN) and p-nitroaniline (PNAn)) copolymer hybrid nanocomposite [An + PNAn/ZrO2]NC as a powder was synthesized and prepared as a thin film using the Sol-Gel spin coating tool. Optical energy bandgaps calculated by Tauc's equation are 2.307 eV and 1.711 eV for the [An + PNAn]BD as a blend and [An + PNAn/ZrO2]NC films, respectively. Whereas the bandgaps calculated by DFT (DMol3) are 2.396 eV and 1.696 eV for the [An + PNAn]BD and [An + PNAn/ZrO2]NC films, respectively. The blend and hybrid nanocomposite films exhibit non-ohmic current-voltage (I–V) behavior. At low temperatures, the conduction mechanism in [An + PNAn]BD is Schottky emission, but the Poole–Frenkel effect is prominent in ZrO2-doped films at high temperatures. The simulated values for the optical properties produced by CATSTEP in DFT are in good agreement with the experimental results. The photovoltaic behavior of the solar cell was investigated. The fill factor ranged from 18.59 to 51.82 %, and the power conversion efficiency ranged from 4.275 to 7.125 % at illumination intensities of 60 and 240 mW/cm2, respectively. The computed negative values of EHOMO and ELUMO energies revealed the product stability as isolated molecules matrix. The values of the optical energy gap indicate that the products are in semiconductors range.

    Toward highly robust reversal-tolerant anodes in polymer electrolyte membrane fuel cells

    Kim H.-T.Kim J.Y.Lee D.-H.Doo G....
    8页
    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryA reversal tolerant anode (RTA) mitigates carbon corrosion under hydrogen starvation by promoting a water oxidation reaction with an oxygen-evolution-reaction catalyst. However, achieving long-lasting and repeatable voltage-reversal tolerance remains a challenge. Herein, we propose highly robust bi-layered RTAs consisting of IrOx and Pt black layers (IrOx//Pt) for use in polymer electrolyte membrane fuel cells. Compared to bi-layered IrOx//Pt/C RTAs, the carbon-free IrOx//Pt RTAs have an exceptionally longer voltage-reversal time and unprecedented level of repeatability. Additionally, placing the IrOx layer on the membrane side of the RTA is more effective in maintaining the water oxidation reaction than placing it on the diffusion layer side. Oxidative dissolution of IrOx in the IrOx//Pt RTAs under repeated voltage reversals emphasizes the importance of lowering the water oxidation potential of RTA. The carbon-free, bi-layered RTA design presented in this work provides a new path for achieving long-lasting and repeatable voltage-reversal tolerance.

    查看更多>>摘要：? 2022 The Korean Society of Industrial and Engineering ChemistryIn this study, the synthesis of neodymium nickelate (Nd2NiO4, NNO) nanoparticles with diverse temperatures were developed by the simple coprecipitation method. The successfully prepared NNO was characterized with various spectroscopic instruments. The surface morphology, size, shape, composition, crystallinity, functionality, bonding, and the presence of elements of the nanoparticles were analyzed by suitable characterization techniques. The electrochemical features were investigated by electrochemical impedance spectroscopy, cyclic voltammetry, and differential pulse voltammetry (EIS, CV, and DPV) methods. As results expected, the modified NNO-500/SPCE sensor displays low electron transfer resistance (Rct), high active surface area, and excellent electrocatalytic activity for the detection of prochlorperazine (PCP) rather than other electrodes. Under optimized electrochemical detections, the DPV study revealed a low limit of detection (LoD), and limit of quantification (LoQ) of 4 nM, and 14 nM with wide linearity of 0.025–1220 μM for PCP at the NNO-500 sensor. In addition, high selectivity, stability, precision, and satisfactory recoveries in biological samples for PCP detection. Thus, our study provides a simplistic but effective method for constructing perovskite-type materials with excellent electrochemical performance.
