Title of Document: CO-SOLVENT ASSISTED SPRAY PYROLYSIS FOR THE PREPARATION OF METAL MICROPARTILCE. Kai Zhong, Doctor of Philosophy, 2012 Directed By: Professor Sheryl H. Ehrman, Department of Chemical and Biomolecular Engineering Metal and bimetallic particles play an important role in catalytic, medical and electronic applications. Various techniques have been developed for the preparation of ...

Herein, an ultrasound-assisted dispersive magnetic micro-solid phase extraction (DM-?SPE) approach, along with electrothermal atomic absorption spectrometry (ETAAS) for the determination of lead at trace level in spring, well, river mineral and tap water samples was developed. The step is based on synthesis PbS, following sonochemical decomposition L-cysteine used as sulphide precursor its anch...

A sonochemical Materials Acceleration Platform was implemented to synthesize CdSe nanocrystals under 625 unique conditions (in triplicate) in less than 6 weeks. The modularity of the workflow is adaptable a variety applications.

The behavior of Pu(iv) and Pu(iii) was investigated in aqueous nitric solutions under ultrasound irradiation (Ar, 20 kHz). In the absence of anti-nitrous reagents, ultrasound has no effect on Pu(iv), while Pu(iii) can be rapidly oxidized to Pu(iv) due to the autocatalytic formation of HNO(2) induced by HNO(3) sonolysis. In the presence of anti-nitrous reagents (sulfamic acid or hydrazinium nitr...

Advanced Oxidation Processes (AOP) using ozone, H2O2, ultrasound (US), ultraviolet radiation (UV), Fenton’s reagent (FeII+H2O2) alone or in combination involving hydroxyl radicals are considered as possible methods of clean and ecologically safe remedial treatment for the degradation of organics. In the present study, comparison of kinetics of photochemical, sonochemical and chemical oxidation ...

background: organophosphorus pesticides are one of the most prevalent usages for pest control in the country. such pesti­cides enter into water sources by different routes. since drinking of contaminated water at the higher doses than the standard level, may causes undesirable effects to human health and ecosystem. the object of this research was to investigate the ef­fect of various parameters...

Elimination of antibiotic activity of waters contaminated with oxacillin by photo-Fenton, TiO2-photocatalysis, sonochemical and electrochemical processes A comparative study on the effects of additives R.A.

A solvent-free procedure for the synthesis of 3-substituted indole derivates from indoles and nitroalkenes under ultrasound irradiation is described. Control experiments disclosed besides mechanical effects, namely agitation, sonochemical effects are the main forces to drive the reaction. In the method, 2-chloroethanol was used to prepare a wide variety of 3-substituted indole derivates. This p...
