    Dehong Teng1,#, Jing Zhang1,#, Xinzhi Luo1, Fei Jing1, Hengwei Wang1, Jing Chen1,* , Chao Yang1, Shaohong Zang1,*, Yingtang Zhou1,2

    Journal of Renewable Materials, Vol.10, No.9, pp. 2378-2391, 2022, DOI:10.32604/jrm.2022.019209 - 30 May 2022

    Abstract Semiconductor photocatalysis is a novel highly efficient and low-cost method for removing organic pollutants from wastewater. However, the photoreduction performance of semiconductors on organic pollutants is limited due to the weak absorption of visible light caused by its wide band gap and low carrier utilization rate resulting from severe electron-holes recombination. In the present study, flower-like NH2-UiO-66 (NU66)/ZnO nanocomposites were prepared using a facile method and exhibited high efficiency under visible light driven photocatalysts. The X-ray diffractometer (XRD), scanning electron microscope (SEM), transmitor electron microscope (TEM), and X-ray photoelectron spectroscopy (XPS) were used to characterize… More > Graphic Abstract

    Journal of Renewable Materials, Vol.10, No.3, pp. 653-663, 2022, DOI:10.32604/jrm.2022.018556 - 28 September 2021

    Abstract Hydrogen production through solar energy is one of the most important pathways to meet the growing demand of renewable energy, and photocatalyst participation in solar hydrolytic hydrogen production has received great attention in recent years in terms of low cost, high efficiency, and flexible design. Particularly, g-C3N4 (Graphitic-like carbon nitride material), as a unique material, can catalyze the hydrogen production process by completing the separation and transmission of charge. The easily adjustable pore structure/surface area, dimension, band-gap modulation and defect have shown great potential for hydrogen production from water cracking. In this review, the most recent More > Graphic Abstract

    KANCHANA M1, RAJASEKARAN E2, KUMAR B1, USHA ANTONY3

    Journal of Polymer Materials, Vol.38, No.3-4, pp. 309-325, 2021, DOI:10.32381/JPM.2021.38.3-4.11

    Abstract The objective of this research work is to investigate the feasibility of fabricating bio-based visual sensor indicators to detect the presence of H2S using inkjet printing. Myoglobin and chitosan were used as indicating and immobilizing materials respectively. 30 mg of myoglobin dissolved in 1 mL of tris buffer with 10% glycerol gave optimum jettability properties. Similarly, drop formation was optimal for 0.50% m/v chitosan solution diluted to 10 cP viscosity. The samples were fabricated in layer-by-layer approach and indicator with 2 layers of chitosan and 4 layers of myoglobin gave maximum sensitivity with 14.42 for 0.7 More >

    FDMP-Fluid Dynamics & Materials Processing, Vol.17, No.6, pp. 1003-1013, 2021, DOI:10.32604/fdmp.2021.015225 - 08 September 2021

    Abstract The falling film of an ionic liquid ([EMIM] [DMP] + H2O) and its effect on a refrigeration system are numerically simulated in the framework of a Volume of Fluid (VOF) method (as available in the ANSYS Fluent computational platform). The properties of the liquid film and the wall shear stress (WSS) are compared with those obtained for a potassium bromide solution. Different working conditions are considered. It is noted that the ionic liquid demonstrates a better absorption capability, with a coefficient of performance (COP) of 0.55. It is proved that the [EMIM] [DMP] + H2O ionic More >

    Yu-Jyun Chen, Xian-Hao Yang, Yun-Yang Chao*

    Phyton-International Journal of Experimental Botany, Vol.90, No.5, pp. 1477-1489, 2021, DOI:10.32604/phyton.2021.015719 - 27 May 2021

    Abstract Nanosilver (10−9 m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation and production. This study examined the effects of nanosilver on growth and development of rice root systems. Study results showed that fresh weight of rice belowground organs and root length both increased significantly by 5% and 25%, respectively, after rice radicles were treated with 2 ppm of nanosilver for three days. However, the H2O2 level reached its peak at 2 days from treatment, but the activities of the antioxidant enzymes… More >

    Abstract Drought is the most common form of abiotic stress that reduces plant growth and productivity. It causes plant injuries through elevated production of reactive oxygen species (ROS). Potassium (K) is a vital plant nutrient that notably ameliorates the detrimental effect of drought stress in the plant. A pot experiment was conducted at the Laboratory of Plant Stress Responses, Faculty of Agriculture, Kagawa University, Japan, under controlled environment of green house to explore the role of K in mitigating drought severity in wheat (Triticum asevitum L.) seedlings. Three days after germination, seedlings were exposed to three water… More >

    Abstract The cell activity of adipose-derived stem cells (ADSCs) is affected by the intracellular reactive oxygen species (ROS) and the level of autophagy. Previous studies reveal that acetyl-L-carnitine (ALC) possesses capacities of resisting oxidative stress and regulating autophagy. Activating molecule in Beclin1-regulated autophagy protein 1 (AMBRA1) plays a key role in initiating Beclin1-regulated autophagy. In the present study, we discovered ALC pretreatment (1 mM, 24 h) significantly increased the activity of ADSCs exposed to H2O2 (100 μM, 2 h) in vitro with improved stemness, and reduced the production of intracellular ROS. In addition, we found for the More >

    Abstract The investigation of Thermal performance in nanofluids and hybrid nanofluids over a curved stretching infinite region strengthens its roots in engineering and industry. Therefore, the comparative thermal analysis in SiO2–H2O and (MoS2–SiO2)–H2O is conducted over curved stretching surface. The model is reduced in the dimensional version via similarity transformation and then treated numerically. The velocity and thermal behavior for both the fluids is decorated against the preeminent parameters. From the analysis, it is examined that the motion of under consideration fluids declines against Fr and λ. The thermal performance enhances for higher volumetric fraction and λ. More >

    Abstract Elemental sulfur has been used as a traditional Chinese medicine to treat the late-onset hypogonadism and impotence without a clarified mechanism for many hundreds of years. In the present study, mice were received sulfur or distilled water for 35 days by daily intragastric gavage at a dose of 250 mg/kg body weight. Then, the serum testosterone level and genes associated with testicular testosterone biosynthesis (TTB) were detected. The gut microbiota was also analyzed by 16S rRNA gene sequencing. Serum testosterone level was significantly increased by 291.1% in sulfur-treated mice. The H2S levels in serum and feces… More >
