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...

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...

One application of physical acoustics is the development of ultrasonic dental instruments for cleaning purposes including descalers and endosonic files. The vibration characteristics of these instruments have been measured by scanning laser vibrometry, SLV. One possible contribution to the cleaning processes is cavitation and we have been using sonochemical methods to characterize cavitation ar...
