stoichiometric tetragonal bal-xsrxtio3 (x = 0.23) nanopowders were prepared by stearic acid gel(sag) method using barium stearate, strontium stearate, tetrabutyl titanate as ba, sr, ti sourcesand stearic acid as complexing reagent. thermal analysis including differential thermogravimetric(dtg) and tg, fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd) andtransmission electr...
Innovative Technology Summary Reports are designed to provide potential users with the information they need to quickly determine if a technology would apply to a particular environmental management problem. They are also designed for readers who may recommend that a technology be considered by prospective users. Each report describes a technology, system, or process that has been developed and...
Thin films of ZnO grown by sol-gel spin method using two different precursors viz. zinc nitrate and zinc acetate have been characterized for their crystalline nature and associated nanostructures. In some cases, the films consist of nanostructures in the form of nanocrystals and nanoneedles of dimensions in the range 15-60 nm. A comparison between the physical characterization and the nanostruc...
