The sonochemical decomposition of volatile organometallic compounds produces high surface area solids that consist of agglomerates of nanometer clusters. For iron pentacarbonyl and tricarbonylnitrosylcobalt, nanostructured metals and alloys are formed; for molybdenum hexacarbonyl, the metal carbide is produced. These sonochemically produced nanostructured solids are active heterogeneous catalys...
Herein, carbon quantum dots (CQDs) are anchored on reduced graphene oxide (rGO) sheets by sonochemical assisted method. The developed dots/reduced (CQDs/rGO) catalyst shows enhancement in the photocatalytic degradation of methylene blue and methyl orange under visible light compared to that individual CQDs rGO components. improved performance CQDs/rGO has been attributed efficient separation ph...
Increasing environmental awareness has led to a growing interest in natural dyes the textile dyeing industry as consumers become more aware of toxicity synthetic that are harmful environment and health. Although environmentally friendly compared dyes, general their performance is less than dyes. Typically, metallic mordants used enhance affinity materials, perhaps this process breaks journey gr...
The potential of ultrasound-assisted technology has been demonstrated by several laboratory scale studies. However, their successful industrial scaling-up is still a challenge due to the limited pilot and commercial sonochemical reactors. In this work, a pilot reactor for laccase-hydrogen peroxide cotton bleaching assisted by ultrasound was scaled-up. For this purpose, an existing dyeing machin...
Fundamental knowledge on intrinsic plutonium colloids is important for the prediction of plutonium behaviour in the geosphere and in engineered systems. The first synthetic route to obtain salt-free intrinsic plutonium colloids by ultrasonic treatment of PuO2 suspensions in pure water is reported. Kinetics showed that both chemical and mechanical effects of ultrasound contribute to the mechanis...
−Metal organic frameworks (MOFs) are porous crystalline materials of one-, two-, or three-dimensional networks constructed from metal ions/clusters and multidentate organic linkers via coordination bonding, which are emerging as an important group of materials for energy storage, CO2 adsorption, alkane/alkene separation, and catalysis. To introduce newcomers in chemical engineering discipline t...
Lignocellulosic wastes are used as feed stock since are abundantly available. The basic problems involved with bioethanol production from lignocellulosic wastes are high consumption of chemicals used for saccharification, delignification and glucose availability. These problems are considered as important themes of the present study. Ultrasound assisted saccharification was carried out using sa...
