Metal-organic frameworks possessing relatively large pores,high surface areas,and unsaturated metal sites are attractive materials for use as electrocatalysts in the reduction of N_(2)to NH_(3).In this work,a MIL-101(Fe)/MoS_(3)hybrid catalyst,prepared by using a precursor-transformation strategy,is shown to be an effective electrocatalyst for the N_(2)reduction reaction(NRR).Under solvothermal conditions,micro-sized octahedral MIL-101(Fe)precursors are converted into ultra-small nanodots,while amorphous MoS_(3)derived from(NH_(4))_(2)MoS_(4)provides a surface suitable for anchoring the MIL-101(Fe)*** asprepared composite exhibits excellent electrocatalytic activity and durability for the NRR with a Faraday efficiency of 36.71%and an NH_(3)yield of 25.7μg h^(-1)mg_(cat)^(-1)at-0.1 V *** in 0.1 M *** results show that the dispersion and adherence of MIL-101(Fe)nanodots on amorphous MoS_(3)improves the exposure of active centers and aids mass transfer,resulting in greatly enhanced catalytic activity and stability.

Objective:To study the effects of the generation 4 polyamidoamine/vascular endothelial growth factor antisense oligodeoxynucleotide(G4PAMAM/VEGFASODN) compound on the expressions of vascular endothelial growth factor(VEGF) and its mRNA of breast cancer cells and on the inhibition of vascular endothelial cells. Methods:We examined the morphology of G4PAMAM/VEGFASODN compound and its pH stability,in vitro transfection efficiency and toxicity,and the expressions of VEGF and its mRNA. Methyl thiazolyl tetrazolium assay was used to detect the inhibitory function of the compound on vascular endothelial cells. Results:The compound was about 10 nm in diameter and was homogeneously netlike. From pH 5 to 10,it showed quite a buffered ability. The 48-h transfection rate in the charge ratio of 1:40 was 98.76%,significantly higher than that of the liposome group(P<0.05). None of the transfection products showed obvious toxicity on the cells. The expressions of both VEGF protein and its mRNA after G4PAMAM/VEGFASODN transfection decreased markedly. Conclusion:With a low toxicity,high safety,and high transfection rate,G4PAMAM/VEGFASODN could be a promising gene vector. Specifically,it inhibits VEGF gene expression efficiently,laying a basis for further in vivo animal studies.

In previous studies, integrative crop management (ICM) improved shoot growth and grain yield of rice (Oryza sativa L.). However, little is known about the effect of ICM on root growth and methane (CH4) emission of paddy rice. In this study, two rice varieties, Wuyunjing 24 and Yongyou 2640, were grown. A field experiment was conducted with three crop management treatments including zero nitrogen fertilization (0N), local farmer practice (LFP), and ICM. Root morphophysiological traits and CH4 emission from the paddy field were investigated. ICM significantly increased mean grain yield by 29.9%, with the effect attributed mainly to an increase in mean total number of spikelets by 26.4% compared to LFP. ICM increased root and shoot biomass, root length, number of roots, root oxidation activity (ROA), root bleeding rate, and root total and active absorbing surface area by respectively 24.4%, 25.7%, 17.1%, 9.3%, 18.7%, 29.5%, 12.1%, and 24.7%. The concentrations of malic, succinic, and acetic acids in root exudates were respectively 5.8%, 6.0%, and 10.5% higher in ICM than in LFP. Compared to LFP, ICM significantly decreased the rate of CH4 emission during emission peak stages and reduced total CH4 emission by 17.1%. The root morphophysiological traits were positively and significantly correlated with grain yield, whereas root length, specific root length, ROA, and root total and active absorbing surface area were negatively and significantly correlated with total CH4 emission. These results suggest that ICM could achieve the dual goals of increasing grain yield and reducing the greenhouse gas effect by improving the root morphology and physiological traits of paddy rice.
