1. Room temperature route to phosphorus nitride hollow spheres

Author

Abstract

Amorphous phosphorus nitride (P3N5) hollow spheres were synthesized via reacting PCl3 with NaNH2 at room temperature. Transmission electron microscopy (TEM) images showed the hollow spheres with a diameter of 80–150 nm. X-ray photoelectron spectra (XPS) were used to determine the molar ratio of 1:1.60 for P:N. The optical properties of the as-prepared P3N5 were investigated. [Copyright &y& Elsevier]

2. A convenient solid-state reaction route to nanocrystalline TiB2

Author

Shi, Liang, Gu, Yunle, Chen, Luyang, Yang, Zeheng, Ma, Jianhua, and Qian, Yitai

Subjects
*NANOCRYSTALS, *TITANIUM diboride, *ELECTRON microscopy
Abstract

Nanocrystalline titanium diboride (TiB2) powders were successfully synthesized at 650 °C by using TiCl4, Mg and MgB2 as the reactants. Transmission electron microscopy images show that typical TiB2 crystallites are composed of uniform particles with the average grain size of about 40 nm. [Copyright &y& Elsevier]
