Despite the rapid progress in the development of catalysts for dye decolorization, the simultaneous catalyzing and product separation to achieve continuous processing remains a great challenge. Here, silver nanoparticle-doped bacterial cellulose (AgNP@BC) nanoporous membrane with AgNP diameter of ~ 8.1 nm is successfully fabricated without employing any other reductants, capping or dispersing agents...
In this work, the carboxylate-functionalized cellulose (CFC) from waste cotton fabrics (WCF) was studied for removal of cationic dyes from aqueous solutions. Instead of using conventional process for esterifying cellulose, which uses sulfuric or perchloric acid as catalysts, and methylene chloride as solvent, a novel mechanochemical approach which requires no catalyst or solvent in the reaction mixture...
A 3D thermomechanical finite element analysis model for laser tube bending is developed based on the software MSC/Marc. The processes of single- and multi-scan are analyzed numerically. The gradient and development of the temperature between the laser scanning side and the nonscanning side leads to the changing complexity of the stress and strain. Consequently, the length of the laser scanning side...
