An extract-composition of traditional Chinese herbal medicine for preventing and treating diabetes has been successfully prepared by researchers from Key Laboratory of Chemistry of Northwestern Plant Resources, CAS. They have received a Chinese invention patent for the technique. The patent is No. ZL：200810189023.6 received on April 27, 2011.
Complicated and expensive organic ligands are normally essential in fine chemical synthesis at preparative or industrial levels. The synthesis of fine chemicals by using heterogeneous catalyst systems without additive organic ligand is highly desirable but severely limited due to their poor generality and rigorous reaction conditions.
Researchers at the R&D Center of Lubricating and Protecting Materials of the Lanzhou Institute of Chemical Physics, CAS (LICP, CAS) have prepared two nickel-based high temperature wear resistant coatings, namely NiCrBSi coating and NiCrBSi/WC-Ni composite coating, on stainless steel by laser cladding.
The surface/interface research group from the Lanzhou Institute of Chemical Physics of the CAS has developed self-healing surface that can recover its water- and oil-repelling qualities after damage (Chem. Commun., 2011, 47, 2324–2326). The work was highlighted by Nature Asia-pacific in the recent issue (NPG Asia Materials featured highlight | ...
Diamond-like carbon (DLC) coating is one of the most promising functional coatings. It possesses many important characteristics such as extremely high hardness, high thermal and chemical stability, and excellent tribological properties.
