Synthesis of Unsymmetrical Ethers Catalysed by Polyvinyl Sulfuric Acid & PVSA / Nano RH SiO2 as a Novel Solid Acid Nanocomposite

The methodology involves preparing polyvinyl sulfuric acid as a solid acid by simple mixing ofpolyvinyl alcohol with chlorosulfonic acid in CH2Cl2 at room temperature. The catalytic ability ofthe solid acid was investigated for the facile conversion of benzylic alcohols to the unsymmetricalethers with aliphatic alcohols in the presence of the solid acid. Results show that the solid acid isan ap...

Green Removal of Toxic Pb(II) from Water by a Novel and Recyclable Ag/γ-Fe2O3@r-GO Nanocomposite

Toxic leadions removed efficiently from water by a newly fabricated, magnetically recyclable, antibacterial nano-Ag/γ-Fe2O3@GOadsorbent, at ambient and teh physiological pH=7. Teh adsorption depends on teh adsorbent dosage, initial Pb(II)concentration, pH and teh contact time. Teh optimum removal efficiency of teh leadion is found to be 93.1%...

Short Cellulose Nanofibril/polyvinyl Alcohol Nanocomposite Fibers

Short cellulose nanofibrils (SCNF) were investigated as a reinforcement for polyvinyl alcohol (PVA) fibers. SCNF fibers were mechanically isolated from hard wood pulp after enzymatic pretreatment. Various levels of SCNF were added to PVA and gel-spun into continuous fibers. The molecular orientation of PVA was affected by a combination of wet drawing during gel spinning and post-hot-drawing at ...

Green synthesis and antibacterial activity of zinc selenide (ZnSe) nanoparticles

Objective(s): Drug delivery is an engineering technology to control the release and delivery of therapeutic agents to target organs, tissues, and cells. Metallic nanoparticles, such as gold nanoparticles (AuNPs) have exceptional properties which enable efficient drug transport into different cell types with reduced side effects and cytotoxicity to other tissues.Materials and Methods: AuNP...
