Nanostructured materials often exhibit unique physical properties, such as fast carrier transport, subwavelength optical waveguiding, and a high surface-area-to-volume ratio. When the size of a material is reduced to nanoscale dimensions, its physical and chemical properties can change dramatically. In addition, nanostructures offer exciting new opportunities for environmental applications. In this review, we aim to provid Read More

Catalytic air oxidation (CAO) is an economical, environmentally friendly, and efficient technology used to treat wastewater that contains refractory organics. This review analyzes recent studies regarding five common types of CAO that use external energy sources (heat, light radiation, microwave, and electricity) or non-oxidizing chemical promoters (nitrites and sulfites). Methods include hydrothermal, electro-assisted, p Read More

Wet air oxidation (WAO) is an attractive technique for sewage sludge treatment. The WAO process and the factors influencing the process are examined in detail, together with the advantages and disadvantages. Catalytic wet air oxidation (CWAO) is emphasized because it can lower operational conditions, and the commonly-used and new homogeneous and heterogeneous catalysts are introduced. Homogeneous cat Read More

Ascorbic acid is the most well-known vitamin found in different types of food. It has tremendous medical applications in several different fields such as in pharmaceuticals, cosmetics, and in organic synthesis. Ascorbic acid can be used as a substrate or mediator in organic synthesis. In this review, we report ascorbic acid-catalyzed reactions in organic synthesis. Several examples are included in this review to demonstrate th Read More

Background: Due to the ubiquitous nature of the ketone functionality, it is considered an important functional group in organic chemistry. Hence, the synthesis of ketones from readily available starting materials is an important chemical transformation in organic synthesis. Consequently, several research efforts have been reported in the literature for the transformation of carboxylic acids to ketones in a one-pot synthesis. Read More

Background: In this study, we show that the AFM method not only allows monitoring the morphological changes in biological structures fixed on the surface due to H-bonds, but also makes it possible to study the self-organization of metal complexes by simulating the active center of enzymes due to intermolecular H-bonds into stable nanostructures; the sizes of which are much smaller than the studied biological objects. The p Read More

Background: A vital section of water pollution mostly comes from the dying industry, which contaminates the water bodies by discharging the effluents into them. Naturally, it is carcinogenic as it contains harmful chemicals and minerals. To prevent this , many researchers have studied the issue and came to an inference that Methylene blue should be removed from wastewater. Many researchers and scientists proposed th Read More
