Carbon-hydrogen bond activation, especially nondirected activation of sp3C-H of simple aromatic bulk chemicals, has been a challenge in modern organic chemistry. It is of both academic significance and application potentials to develop new activation strategies of sp3C-H and apply them in the functionalization of aromatic compounds.
Researchers from Key Laboratory of Chemistry of Northwestern Plant Resources, Chinese Academy of Sciences (CAS), have invented a method for preparing nano natural medicinal material particles by liquid-phase ultrasonic technology. They have received a Chinese invention patent for the technique on June 27. The patent number is ZL200910117753.X.
Graphene, an atomic-layer thick two-dimensional (2D) carbon nanostructure, has attracted tremendous research interests owing to its outstanding electronic, optical, thermal, and mechanical properties and theoretically high surface area of ～2600m2g-1 and therefore showed a variety of applications in nanoelectronics, sensors, batteries, supercapa...
