Summary: Polypyrrole (PPy) microtubes with an actinomorphic morphology are synthesized by a chemical method in the presence of an inclusion complex (IC) of mono [6‐deoxy‐6‐(2‐butenedinitrile‐2,3‐dimercapto sodium salt)]‐β‐cyclodextrin (6‐mnt‐β‐CD) with methyl orange (MO) as a dopant in aqueous solution. The morphologies of the obtained PPy were studied using transmission electron microscopy (TEM). It was found that the IC of 6‐mnt‐β‐CD with MO significantly affects the morphology of the resulting PPy.

The first satellite laser ranging system for daylight tracking in China was set up at Shanghai Observatory, Chinese Academy
of Sciences. Both false alarm probability due to strong background noises and detection probability of the laser returns with
single photon level from satellite in daylight for our system are analysed. The system design and performance characteristics
of subsystems, adopted techniques and satellite ranging observations are given.

Pulse corona plasma was used as an activation method fordehydrogenative coupling of methane at the normal temperature and under' the normal pressure. The exprimental results showed that a great enhancement in the selectivity to C2 was achieved by the combination of pulse corona plasma with a y-Mn2OO3/Y-A12O3 catalyst. The distribution of C2 hydrocarbons was mainly affected by the power input and the nature of the catalyst. In addition, the gas stream direction exerted an influence upon the C2 yield, especially at higher power input. 相似文献
