Characterization of Surface Modification of Woody Biomass Grafted with Acrylic Monomers

Modification of Silica surface by Titanium sol synthesis and characterization

Hydrophobic silica titanium nanoparticles (STNPs) were successfully synthesized by the sol-gel process using liquid modification. Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) studies were demonstrated the attachment of titanium on the silica surface. Titanium content enhanced the agglomeration of particles as shown in topography results. The N2 adsorption-desorption followed T...

Surface Modification by Chemically Grafted Initiators

To modify the surface properties of inorganic materials, we successfully covalently attached a stable monolayer, with high grafting density, of N,N(diethyl)dithiocarbamoylbenzyl(trimethoxy)silane on the surface of silicon wafers and glass substrates, thereby creating a surface-grafted photoinitiator for “living” free radical photopolymerization. The surface-grafted initiators were utilized for ...

Synthesis and characterization of acrylic acid grafted gum tragacanth and its effect in Fe2+ removal

In this paper, grafting of acrylic acid monomer on Gum tragacanth was performed. Variable of experiment included concentration of initiators and monomer, time, and temperature. Grafting efficiency was measured in the term of percentage of grafting (%G) and percentage of grafting efficiency (%E). Effectiveness of grafted gum in ferrous ion removal at different condition was assessed. According t...
