In this research, ZnO nanoparticles modified with imidazole in O-xylene solution and characterized with Fourier transform infrared FTIR spectroscopy. Then, polyaniline-ZnO unmodified and imidazole modified nanocomposites were synthesized via in-situ emulsion polymerization method. The synthesized nanocomposites were characterized by FTIR and scanning electron microscopy SEM. The anti-corrosion ...

We propose the very first "Nernstian biosupercapacitor", a biodevice based on only one redox polymer: poly(vinyl imidazole-co-allylamine)[Os(bpy)2 Cl], and two biocatalysts. At the bioanode PQQ-dependent glucose dehydrogenase reduces the Os3+ moieties at the polymer to Os2+ shifting the Nernst potential of the Os3+ /Os2+ redox couple to negative values. Concomitantly, at the biocathode the redu...

Nanostructured membranes containing structural and proton-conducting domains are of great interest for a wide range of applications requiring high conductivity coupled to high thermal stability. Understanding the effect of nanodomain confinement on protonconducting properties in such materials is essential for designing new, improved membranes. This relationship has been investigated for a lame...

Xanthan gum (XG) is natural polysaccharides used in food industries as stabilizers and thickener agents. The problem is that some food products are found to be contaminated by pathogenic bacteria such as Escherichia coli (E. coli) and Staphyloccus aureus (S. aureus) that reduce their shelf life. This research aims to synthesize biodegradable antibacterial XG-grafted-poly(N-vinyl imidazole) PVI ...

poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. the aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl group in poly(vinyl acetate), as well as the molecular wei...

background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...
