A small fixed-mirror Michelson interferometer has been built in Frascati to experimentally study the alignment method that has been suggested for VIRGO. The experimental results fully confirm the adequacy of the method. The minimum angular misalignment that can be detected in the present setup is 10 nrad/ √ Hz.
Nanometric-sized LiNi<sub>0.8</sub>Co<sub>0.2</sub>O<sub>2</sub> powders were obtained from the resins synthesized by the polymerization of citric acid and cellulose. The powder calcined at 600degC exhibited a pure high temperature phase of LiNi<sub>0.8</sub>Co<sub>0.2</sub>O<sub>2</sub>. The surface response method was applied for the optimal preparatory… (More)
