In the present study, titanomagnetite nanoparticles (Fe3-xTixO4 NPs) were synthesized via coprecipitation approach and then functionalized using 3-trimethoxysilylpropyl chloride silan coupling agent followed by tetrabutylammonium asparaginate through a facial and newly one-pot procedure to afford an ionic liquid (IL)-modified Fe3-xTixO4 NPs.
The powerful oxidative action of ozone provides basis for development of novel or improved technologies which are widely used in ecology and industry. Special attention is paid to purification of waste gases, water, and soils. The disinfection and cleaning of drinking and process water are considered in detail. Applications of ozone in chemical, pharmaceutical and perfume industries, cosmetics, cellulose, paper and sugar industries, flotation, microelectronics, and many others are also examined in the review.
Structural modification of 5,7-dimethyl-6-phenylazo-3Н-thiazolo[4,5-b]pyridin-2-one relative to the 3rd position of basic heterocycle allows to use its functionalization as the convenient method for the synthesis of various derivatives and diversification of a series of N3 substituted thiazolo[4,5-b]pyridines. The efficient synthetic protocol for aminomethylation proceeding was developed which led to obtaining a series of novel 3-(phenylamino)-methyl derivatives of 5,7-dimethyl-6-phenylazo-3Н-thiazolo[4,5-b]pyridin-2-one.
