Abstract In marine environments, the durability of reinforced concrete structures such as bridges, which suffer from the coupled effects of corrosion and fatigue damage, is significantly reduced. Fatigue loading can result in severe deterioration of the bonds between reinforcing steel bars and the surrounding concrete, particularly when reinforcing bars are corroded. Uniaxial tension testing was conducted under static loading and fatigue loading conditions to investigate the bonding characteristics between corroded reinforcing bars and concrete. An electrolyte corrosion technique was used to accelerate steel corrosion. The results show that the bond strength was reduced under fatigue loading, although the concrete did not… More >

Abstract Capsule shells have been successfully fabricated from water-soluble chitosan (WSC) with the addition of alginate and Gembili starch. WSC was synthesized from crab shell chitosan by depolymerization reaction. The capsule shells were made with the composition of WSC: Alginate, 2:1, 3:1 and 4:1 (w/w) with and without the addition of Gembili starch. Gembili starch was added with a ratio of Alginate: Starch, 1:1 (w/w). The capsule shell properties were evaluated according to Indonesian Pharmacopoeia standard. The solubility test showed that the capsule shells were comply with the standard. The highest degrees of swelling in water and HCl 0.1 N solution… More > Graphic Abstract

Abstract The impact of land consolidation on the soil microbial PLFA diversity is of great importance for understanding the effective arable land usage, improving agricultural ecological conditions and environment. In this study, we collected the soil samples (0–20 cm) in experimental plots with 0 (Z₀), 1 (Z_1a) and 4 (Z_4a) years of land consolidation in the forest station of Ningbo City, Zhejiang Province, southeastern China. The results were analyzed using ANOVA for randomized block design. Compared with control (Z₀), the soil pH value under Z_1a treatment increased by 14.6%, soil organic carbon (SOC) content decreased by 65.4%, so did the PLFA… More >

Abstract Now-a-days nanotechnology is one of the booming fields for the researchers. With the increase in industrialization mainly textile, paper, medicine, plastic industry, there is an increase in concentration of organic dyes as pollutant. Release of harmful dyes in water bodies has become a serious issue, as most of the dyes are carcinogenic and mutagenic in nature and causes various diseases. Therefore, there is a requirement to find out new approaches for efficient treatment of effluent containing dyes. Nanoparticles are one of the potential solutions to this problem. They can be synthesized from different methods, however synthesis of nanoparticles from different… More >

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 the prepared samples, indicating that… More > Graphic Abstract

Abstract To study the roles and association of murine double minute gene 2 (MDM2) and fructose-1,6-biphosphatase (FBP1) in human hepatocellular carcinoma (HCC), growth response of human HCC cells was assessed using proliferation and apoptosis assay. Pro-survival AKT signaling associated proteins (p-AKT, survivin and cleaved caspase 3) were assessed using western blotting. The correlation between MDM2 and FBP1 was assessed using co-immunoprecipitation combined with ubiquitination assay. Our data suggested that low expression of FBP1 was correlated with high levels of MDM2 in HCC cell lines (Huh7 and Hep3B). Overexpression of FBP1 resulted in anti-proliferation, pro-apoptosis, the up-regulation of cleaved caspase 3 while… More >

Abstract A facile method, focusing on emulsification, chain extension and dispersion process in preparing waterborne polyurethane, was developed to prepare emulsion with rod-like nanoparticles. The facile method involves a water addition procedure by in situ generated water to react with polyurethane prepolymer instead of the external water addition process. As a comparison, waterborne polyurethane was synthesized through the external water addition process. According to the characterization methods including FTIR, ¹H-NMR, TEM and water swelling experiments, it is suggested there are two kinds of hydrogen bonds interactions in hard/soft domain of the novel polyurethane, and the phase separation of hard/soft domains increases… More > Graphic Abstract

Abstract The mitogen-activated protein kinase (MAPK) cascade is important in stress signal transduction and plant development. In the present study, we identified a rice (Oryza sativa L.) mutant with reduced fertility, Oryza sativa mitogen-activated protein kinase 6 (osmapk6), which harbored a mutated MAPK gene. Scanning and transmission electron microscopy, quantitative RT-PCR analysis, TUNEL assays, RNA in situ hybridization, longitudinal and transverse histological sectioning, and map-based cloning were performed to characterize the osmapk6 mutant. The gene OsMAPK6 was expressed throughout the plant but predominantly in the microspore mother cells, tapetal cells, and microspores in the anther sac. Compared with the wild type,… More >

Abstract Myocytes power the movement of all organs in the body. Damage to and degradation of myocytes causes hypokinesia and muscle-related degenerative diseases. Apigenin, a kind of flavone, is being used to treat many disorders. It exerts a host of different pharmacological activities, such as anti-inflammatory, anti-mutagenic, cardioprotective, and antioxidant effects. Accordingly, apigenin is considered a promising candidate for myocyte protection. In this review, we introduced the characteristics of apigenin. The means of apigenin protection of myocytes as well as the mechanism were summarized and discussed. The protective effects can be classified into proliferation-promoting, anti-inflammatory, atrophy-preventing, metabolism-increasing, and antioxidative effects. Additionally,… More >

Abstract Geopolymers have been developed to various catalysts due to their advantages. However, low conductivity restricts their application in the electrocatalysis field. In this study, an α-Fe₂O₃/circulating fluidized bed fly ash based geopolymer (CFAG) composite anode was fabricated using a facile dip-coating method by loading α-Fe₂O₃ in the matrix of CFAG. The effects of α-Fe₂O₃ content on the composition, surface morphology and electrochemical performance of α-Fe₂O₃/CFAG composite anode were investigated. The X-ray diffraction (XRD) and scanning electron microscope (SEM) results demonstrated that α-Fe₂O₃ was successfully inlaid with the surface of amorphous CFAG matrix. The electrochemical measurements indicated that α-Fe₂O₃/CFAG composite anode… More > Graphic Abstract
