Observation of Radial Propagation of Electrostatic Fluctuations in Edge Plasma of the Sino United Spherical Tokamak

Radial propagation of electrostatic fluctuations in the edge plasma of Sino-United Spherical Tokamak (SUNIST) has been measured using Langmuir probes. The propagation characteristics of the floating potential fluctuations are analysed by the two-point correlation technique. The results show radially outward propagation of the turbulent fluctuations at all measured radial positions. The power-average wavenumber profile is approximately constant in plasma edge region and suddenly increases to the limiter. These results are in good agreement with the model predictions proposed by Mattor which suggests that the drift wave propagation may be a source of edge turbulence.     

柠檬酸溶胶凝胶法制备LiCoO_2电极材料及其表征

目前研究较多的锂离子电池正极材料主要有LiCoO2、LiNiO2和LiMn2O4犤1犦,虽然LiCoO2的成本相对较高,但LiCoO2具有最为优良的电化学性能,如高且平稳的充放电平台、高比容量以及良好的循环性能犤2犦,是目前应用最广泛的商品化电极材料。LiCoO2材料主要采用高温固相法犤3～5犦制备,该方法工艺简单,容易实现大规模生产,但缺点是需要较高的焙烧温度和较长的焙烧时间,且反应原料混合均匀程度有限,易导致非化学计量、非均相以及不规则的颗粒形貌等,因此材料的比容量、循环寿命等电化学性能以及反应的可控性还不甚理想。研究表明犤6犦电极材…     

γ-Al2O3表面原位合成Ni-Al-CO3LDHs研究

Ni-Al-CO₃LDHs/γ-Al₂O₃have been prepared using an in-situ synthesis technique. NH₃·H₂O was chosen as activation agent of Al on the γ-Al₂O₃surface as well as precipitant. Ni-Al-CO₃LDHs/γ-Al₂O₃was synthesized by controlling the reaction conditions such as temperature, concentration of Ni²⁺ and initial pH. The crystalline structure, chemical composition and porous structure were characterized by means of XRD, FT-IR, TG-DTA, ²⁷Al MAS-NMR and N₂ adsorption-desorption. The resulting sample of Ni-Al-CO₃LDHs/γ-Al₂O₃possesses higher specific area and narrower pore distribution, in which Ni-Al-CO₃LDHs are located on the surface of γ-Al₂O₃and share the same Al-O bonds with the γ-Al₂O₃lattice. Finally a possible structural model was proposed to account for the porous characters of Ni-Al-CO₃LDHs/γ-Al₂O₃.
