	Abstract:Oxygen evolution reaction (OER) is closely related to numerous energy-related applications so that developing high-activity, durable and cost-effective electrocatalysts for OER has been an inevitable trend. Prussian blue analogues (PBAs), a kind of metal organic frameworks (MOFs), which have been paid more attention in the filed of electrocatalysis because of unique framework structure and adjustable components. Herein, we synthesis a series of Ni-Co PBAs via modulating metal ratio by a coprecipitation method and then anneal the as-prepared Ni-Co PBAs, which used as OER catalysts. We found that as the increasing of nickel content, the size of catalysts decreases, which resulting in an increasing of specific surface area and electrochemical active sites, thereby improving the performance of OER. Furthermore, benefiting from the minimum size with largest specific area, largest electrochemical active surface area with different and abundant active sites, the Ni-Co-31 oxides shows a small overpotential of 340 mV at a current density of 10 mAocm-2, a small Tafel slope of 89 mVodec-1, which is superior to other catalysts prepared. This work proves the great significance of PBAs derivatives with different metal ratios for OER performance, which is meaningful for the preparation and mass production of efficient electrocatalysts.

	Abstract:Li2Mn1-xMgxSiO4/C cathode material for lithium-ion batteries has been synthesized by a sol-gel method using LiCH3COOo2H2O, Mn(CH3COO)2o4H2O, Mg(CH3COO)2o4H2O, and Si(OC2H5)4 as starting materials under Ar/H2 atmosphere. Crystal structures and morphology of the as-prepared compounds were characterized by X-ray Powder Diffraction (XRD) and scanning electron microscopy (SEM). The Li2MnSiO4 material maintains orthorhombic structure with up to 10 wt % Mg doping on the Mn sites. Electrochemical tests of the cathode materials reveal that Mg doping can improve the specific capacity of Li2MnSiO4. An initial specific discharge capacity of 229 mAh g-1 can be achieved for the Li2Mn1-xMgxSiO4/C (x=0.1) cathode material at a current density of 16.65 mA g-1. The deterioration mechanism is also discussed based on the XRD and X-Ray Photoelectronic Spectroscopy (XPS) experiments.

	Abstract:This paper reports the preparation of dodecanethiol self-assembled monolayers (C12SH-SAMs) on polycrystalline gold electrodes in a magnetic field. The qualities of C12SH-SAMs were characterized by both cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results show that highly dense and well-ordered SAMs could form in a relatively short time (3 h), which had similar properties as the SAMs formed by common immersing protocol (24 h), indicating that the rate of SAMs formation increased under an external magnetic field compared with the natural self-assembly process. Moreover, the results of CV and EIS measurements also suggested that the presence of a magnetic field had influenced the properties of the SAMs; the stronger magnetic intensity can help to obtain more denser and well-ordered SAMs. This may be due to the magnetohydrodynamic effect and the orientation function of magnetic field on molecules.
