[en] Selective Dissemination of Information (SDI) Service, which is an important component of intelligence, is the intelligence researcher to select key subjects and major issues and key technology or innovation goals under the actual needs of scientific research personnel issues, using network communication technology and database technology and information retrieval technologies, sustained and in a timely manner to track all kinds of literature for the front-line services, until the completion of research topics or key problem-solving. Library of China Institute of Atomic Energy is struggling to meet the diverse needs of customers, targeted to provide a lot of useful information for scientific researchers to use less time as possible to obtain as much intelligence information, and to research workers and leading to the successful completion of research tasks, and various decisions. The implementation of SDI services to identify clients and scope, to format SDI service team, to determine the SDI service principles and service mode. SDI services Selective demand intelligence researchers have been asked to improve their quality, to improve their interpersonal communication skills. (author)

[en] Highlights: • LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 cathode materials have been synthesized by citric acid-assisted combustion method. • LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4@Ag cathode materials with 4 wt% silver in Ag"0 state coating layer on the surface of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 have been prepared by electroless plating technique. • The Ag-coating improves the electronic conductivity and the surface stability of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4. • LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4@Ag exhibit enhanced cycling stability and rate capability. - Abstract: Silver (Ag) coated LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 (LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4@Ag) was prepared by electroless plating method. The microstructure, surface morphology and electronic conductivity of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4@Ag were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and electronic conductivity tests. The results showed that 4 wt% silver was tightly coated in Ag"0 state on the surface of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 to form a uniform Ag-coating layer of about 30 nm. Electrochemical tests stated clearly that the cycling performance of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4@Ag was more stable and the rate capability was more outstanding than that of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 due to the coating of Ag on the surface of LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 by improving the electronic conductivity, preventing LiNi_0_._4_9Mn_1_._4_9Y_0_._0_2O_4 from being attacked by electrolyte, decreasing the electrochemical polarization during cycling and increasing the lithium ion diffusion coefficient on cathode materials

[en] Wheat-like silver nanoparticles (AgNPs) have been facilely synthesized by using two-step reduction method. The initial AgNPs are reduced from silver nitrate in the first step. Effects of ethyl cellulose concentration on the structure and morphology evolution of AgNPs are systematically investigated in the second step. With increasing the concentrations of ethyl cellulose, the AgNPs evolves from cauliflower-like particles to wheat-like species via a transitional shape of slender particles. The trade-off between oxidation of nitric acid and reduction of L-ascorbic acid under the induction of ethyl cellulose dispersant modifies the morphology of AgNPs, contributing to forming various shapes. The phase structure of synthesized AgNPs remains crystalline and independent of ethyl cellulose concentration. Our works indicate that such a wet-chemical method provides an easy-to-do approach for preparing AgNPs with specific shapes. (paper)
