✦ Synopsis

Monoclinic CuO nanoparticles were prepared by using a onestep solid state reaction method under ambient conditions. The CuO particles with an average size of 12 nm were pressed into pellets under high pressure. They were studied by X-ray photoelectron spectroscopy (XPS), X-ray di4raction (XRD), transmission electron microscopy (TEM), and Raman spectroscopy. The CuO grains in pellets grow with time at room temperature. The gradual increase in the grain size with time is clearly re6ected in their Raman spectra and the XRD results. The correlation between the Raman spectra and the crystal dimension is discussed.

CuO nanoparticles were successfully prepared by a one-step solid-state reaction under ambient conditions. Three pellet samples with different grain sizes were obtained by annealing at high temperature. The room temperature Raman spectra of these samples show that as the grain size decreases, the Ram

## Abstract In this article, amphiphilic starch nanocrystals were synthesized by graft copolymerization of starch nanocrystals with styrene in aqueous emulsion system. The starch nanocrystals of size around 50 nm were used, which were prepared by acid hydrolysis of corn starch. The structure of sta
