Nontoxic and earth abundant nanostructured semiconductors have experienced wide attention of researchers recently. One of the more studied material is Iron pyrite (FeS2) owing many different promising applications. Herein, the synthesis of nanostructures by varying the reactant precursors of iron and sulphur has been reported. The molar ratio of iron and sulphur precursors play a crucial role in determining the quality of nanostructures. This work further advances synthesis with pyrite purity, structure control and then promotes use in photovoltaics, photocatalysis and photoelectrochemistry applications. Copyright © 2017 VBRI Press.

Boron carbide is well known metallurgical product used in cutting/coating tool industry. Nanostructured boron carbide finds its application in medical, optical and defence industry due to its structural, mechanical and optical properties. In present paper, we report the effect of processing parameters (reaction time and temperature/pressure) on the synthesis of nanostructured boron carbide. Detailed X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM and TEM) analysis was done along with theoretical studies of pressure. Results show that the best temperature for synthesis of nanoscale boron carbide is 800 °C. Copyright © 2017 VBRI Press.
