Innovative bactericidal adsorbents containing modified xanthan gum/montmorillonite nanocomposites for wastewater treatment

Highly porous copper-supported magnetic nanocatalysts: made of volcanic pumice textured by cellulose and applied for the reduction of nitrobenzene derivatives

“…[21][22][23][24][25] The use of cellulose (CLS) in this work, because it is natural, has been a strong indication of how important green chemistry was to us in this work. 26,27 There are many reasons why cellulose, as a substantial polymeric substrate with a biocompatible origin, is used in this work; one of the most important of these is that cellulose, due to its large number of hydroxyl (-OH) functional groups, can form physicochemical hydrogen bonds with the -OH groups of pumice, which can lead to integration in the composite. On the other hand, the rest of the hydroxyl functional groups of cellulose, which are free of hydrogen bonds with the hydroxyl functional groups of pumice, are suitable for chelation by cationic metals such as copper and palladium and can form heterogeneous catalytic composites from natural components; this is one of the most important properties of this composite.…”

The controlled synthesis and DFT investigation of novel (0D)–(3D) ZnS/SiO2 heterostructures for photocatalytic applications

“…The need for clean water is growing in all regions of the world, while renewable water resources have become limited due to the effects of climate change and human usage. [1][2][3][4][5][6] This environmental scarcity has pushed the research community to adopt new methods for the systematic management of clean water, as traditional techniques are not sufficient to remove pollutants such as fragments of organic dye waste in rivers. [7][8][9][10][11] Photo-removal can represent the best, simplest, and most sustainable route for achieving the oxidation process using sunlight.…”

One-pot green synthesis of antimicrobial chitosan derivative nanocomposites to control foodborne pathogens

“…4,5 Silver nanoparticles are synthesized via chemical reduction. [6][7][8] The eco-friendly synthesis of AgNPs has been done using non-toxic reducing agents including seed extracts, living organisms, and plant leaves. [9][10][11] Recently, AgNPs have been synthesized in the presence of non-toxic highly available polysaccharides such as chitosan, xanthan gum, locust bean gum, and agar as self-reducing agents.…”

“…[9][10][11] Recently, AgNPs have been synthesized in the presence of non-toxic highly available polysaccharides such as chitosan, xanthan gum, locust bean gum, and agar as self-reducing agents. 7,12,13 Chitosan (Ch) is a modied cationic polysaccharide composed of b-(1/4)-linked copolymers of glucosamine and Nacetylated glucosamine units (Fig. 1a).…”

“…Ag has good antimicrobial activity given that it destroys the cell membrane of microorganisms through its interactions with the phosphorous and sulfur elements present in the cell membrane, which leads to a disturbance in its functions. 7,37 An increase in the concentration of AgNPs led to an increase in antimicrobial activity for the TMC/Ag nanocomposites because of the increase in the surface area of the Ag nanoparticles, which enhances the interactions with the cell wall of microorganisms.…”
