Hexagonal wurtzite ZnO nanoparticles with high crystallinity have been synthesized via a simple, convenient, and one-step solid state reaction at room temperature. A full plastic D149-sensitized solar cell based on the resultant ZnO nanoparticles can be fabricated at room temperature with compression post-treatment and presents an energy conversion efficiency of 3.76% (AM 1.5G 100 mW﹞cm每2), which is comparable to the device fabricated with ZnO obtained using the conventional high temperature sintering process.

LiCoO2 nanowires have been synthesized by a facile strategy. The as-prepared LiCoO2 nanowires exhibited excellent rate capability and satisfactory cycle stability, with the charge and discharge capacities becoming stabilized at 100 mA﹞h/g at a rate of 1000 mA/g after undergoing 100 cycles. The favorable electrochemical performance of the LiCoO2 nanowires can be attributed to their one-dimensional nanostructure and the exposure of (010) active planes.

The amphiphilic block copolymer dextran-b-poly(D,L-lactide) has been synthesized and the size of the nanoparticles formed were found to be tunable between 15 to 70 nm by changing the molecular weight of the two polymer chains. In vitro and in vivo studies show that dextran-b-poly(D,L-lactide) is a promising new biomaterial for nano-sized controlled drug delivery carriers.
