X-ray powder diffraction (XRD) is an essential component of research into use of organometallic precursors as a route to low temperature (<500 “C) synthesis of bulk compound semiconductors. This paper illustrates the use of XRD to study solid solution behavior in the systems SnS-SnSe and PbS-CdS. XRD characterization demonstrated that phase pure intermediate members of the Sn(S,Se) solid soluti...

Manganese oxide (MnO 2 ) microspheres are prepared using an ultrasonic spray pyrolysis (USP) process. A mixed solution of potassium permanganate and hydrochloric acid is nebulized into microsized droplets, which are then carried by air fl ow through a furnace tube. Each microdroplet serves as one microreactor and produces one microsphere. Upon heating, KMnO 4 is decomposed into MnO 2 microspher...

Microwave energy (MWe) is, nowadays, widely used as a clean synthesis tool to improve several chemical reactions, such as drug molecule synthesis, carbohydrate conversion and biomass pyrolysis. On the other hand, its exploitation in enzymatic reactions has only been fleetingly investigated and, hence, further study of MWe is required to reach a precise understanding of its potential in this fie...
