Journal ArticleDOI
Sonochemical decomposition of perfluorooctane sulfonate and perfluorooctanoic acid.
TL;DR: The shortening of perfluorocarbon chain of PFOS and PFOA leads to the lowering of the toxicity in view of the decrease of the persistence, and the technique would contribute to the remediation of the environmental pollution by these compounds.
Journal ArticleDOI
Sonochemical synthesis of gold nanoparticles: effects of ultrasound frequency.
TL;DR: The results suggest that the rate of Au(III) reduction as well as the size distribution of Au particles are governed by the chemical effects of cavitation and are not significantly affected by the physical effects accompanying ultrasound-induced cavitation.
Journal ArticleDOI
Sonochemical preparation of bimetallic nanoparticles of gold/palladium in aqueous solution
Yoshiteru Mizukoshi,Kenji Okitsu,Yasuaki Maeda,Takao A. Yamamoto,Ryuichiro Oshima,Yoshio Nagata +5 more
TL;DR: In this paper, a sonochemical method was used to extract bimetallic nanoparticles composed of gold and palladium, which were then reduced by ultrasound irradiation in the presence of sodium dodecyl sulfate.
Journal ArticleDOI
Sonochemical degradation of azo dyes in aqueous solution: a new heterogeneous kinetics model taking into account the local concentration of OH radicals and azo dyes
TL;DR: A new kinetics model taking into account the heterogeneous reaction kinetics similar to a Langmuir-Hinshelwood mechanism or an Eley-Rideal mechanism is proposed, based on the local reaction site at the interface region of the cavitation bubbles, where azo dye molecules are quickly decomposed.
Journal ArticleDOI
Catalytic Technologies for Biodiesel Fuel Production and Utilization of Glycerol: A Review
TL;DR: In this paper, the best selection of BDF production systems including raw materials, catalysts and production technologies are reviewed, as well as some recent studies on the utilization of glycerol.
