Using a potential model with relativistic correction we evaluated the spectrum, le-pton decay widths and radiative transition widths of heavy quarkonium systems.
We found that the poly methacrylates prepared by modified microemulsion polymerization have properties of high glass transition temperature (Tg) and rich syndiotacticity.
The synthsis methods of N-sulfuryl substitude hetercycles by the reaction of alkyne with sulfamide catalyzed by diverse transition mentals were reviewed in this paper.
This article discusses the femto-chemistry, because it involves femtosecond laser pulses, and its research or monitor into chemical processes of transition state and intermediate.
The catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals.
The bright coloured product with good tinctorial power and stability was obtained by the crystal transition and surface treatment to carbazole violet, which is prospect.
