FeNi-LDH Coated With Orange-Peel Carbon Aerogel for Oxygen Evolution Reaction.

In this work, the waste orange-peel was used as carbon source, and the orange-peel derived carbon material can be obtained through simple pyrolysis. Then, we designed the structure of orange-peel carbon aerogel grown on iron-nickel layered double hydroxides in situ to achieve the effect of carbon coating (FeNi-LDH/CA). The oxygen evolution reaction catalytic performance of FeNi-LDH/CA is excellent, far exceeding that of commercial RuO.

p38 Signaling Mediates Naringin-Induced Osteogenic Differentiation of Porcine Metanephric Mesenchymal Cells.

Objective: To explore the potential of metanephric mesenchymal cells (MMCs) for osteogenesis and naringin's ability to enhance this process and its molecular mechanism.

Methods: Porcine MMCs at 70 days of gestation were used as tool cells, cultured in osteogenic induction medium, identified by immunocytochemistry staining. Osteogenic potential of porcine MMCs and naringin's ability to enhance this process was tested by detecting changes in cell viability, alkaline phosphatase (ALP) activity, the expression of runt-related transcription factor 2 (Runx2), osteopontin (OPN) and osteocalcin (OCN), and the formation of mineralized nodules, and the application of the p38 signaling pathway inhibitor SB203580 vitiated the osteogenesis-promoting effect of naringin.

Inactivation of biofilms by thymoquinone in combination with nisin.

is one of the most important foodborne pathogens that can persist in leafy green vegetables and subsequently produce biofilms. In this study, the synergistic effect of thymoquinone and nisin in reducing biofilm formation of on lettuce was evaluated, and their anti-virulence and anti-biofilm mechanisms were also investigated. At concentrations ranging from 0.

Quorum Sensing Inhibition and Metabolic Intervention of 4-Hydroxycinnamic Acid Against .

The natural product 4-hydroxycinnamic acid (HA) was firstly isolated from the metabolites of , one endophytic fungus from leaves. The anti-QS potential of HA was evaluated by β-galactosidase assay and acylated homoserine lactones (AHL) analysis. The MIC of HA was > 1.

Supercapacitive Performances of Ternary CuCoS Sulfides.

Currently, ternary CuCoS sulfides are intensively investigated as electrode materials for electrochemical capacitors due to their low cost, high conductivity, and synergistic effect. The research of CuCoS materials for energy storage has gradually grown from 2016. The supercapacitive performances of CuCoS electrodes for electrochemical capacitors are briefly reviewed in this work.

The Synthesis of NiCoO-MnO Core-Shell Nanowires by Electrodeposition and Its Supercapacitive Properties.

Hierarchical composite films grown on current collectors are popularly reported to be directly used as electrodes for supercapacitors. Highly dense and conductive NiCoO nanowires are ideal backbones to support guest materials. In this work, low crystalline MnO nanoflakes are electrodeposited onto the surface of NiCoO nanowire films pre-coated on nickel foam.

[Effects of Diallyl Disulfide on the Proliferation and Apoptosis of Epithelial Ovarian Cancer Cells by Inducing G2/M Arrest].

Objective To explore the effects of diallyl disulfide(DADS)-induced G2/M phase arrest on proliferation and apoptosis of ovarian cancer cells and its possible molecular mechanism.Methods DADS was used to incubate SK-OV-3 and OVCAR-3 cells,respectively,in different concentrations. Cell proliferation was measured by MTT assay and cell apoptosis rate was detected by flow cytometry assay.

The effects of melamine on the formation of carbon xerogel derived from resorcinol and formaldehyde and its performance for supercapacitor.

Carbon aerogel/xerogel can be easily tuned to have hierarchical pores ranging from micropores to macropores. Nitrogen doping is considered to enhance the wettability and conductivity of the carbon electrode, hence improve the electrochemical performance. To prepare N-doped carbon xerogel and study the effects on the structure and the electrochemical performance of resorcinol and formaldehyde derived carbon xerogel, a series of Resorcinol-Melamine-Formaldehyde derived N-doped carbon xerogel were prepared by a facile sol-gel process and ambient drying method.

An ethical evaluation index system for clinical approval of medical technology in China: A structural equation model study.

Objective: To construct a quantitative ethical evaluation index system for the clinical approval of medical technology in China.

Methods: Exploratory factor analysis (EFA) and first-order confirmatory factor analysis (CFA) based on a structure equation model (SEM), higher-order CFA and normalisation were used to establish an ethical evaluation index system for the clinical approval of medical technology. Data were processed in SPSS 13.
