The surface parameter of nanoparticles such as hydrophobicity and a hydrophilicity on protein structure and function is very important. In this study, conformational changes of glucose oxidase (GOx) in the mercaptopurine: GNPs and 11-mercaptoundecanoic acid: GNPs as a hydrophobic and a hydrophilic GNPs surface was investigated by various spectroscopic techniques, including: UV-Vis absorption, f...

The goal of the present study is to prepare a room temperature cured hydrophobic and self-cleaning nano-coating for power line insulators. As a result, the installed insulators operating in power lines can be coated without being removed from the circuit and without the need to cut off power. For this purpose, hydrophobic silica nanoparticles were synthesized by sol-gel method using TEOS and HM...

The produced liquid water in cathode catalyst layer (CCL) has significant effect on the operation of proton exchange membrane fuel cell (PEMFC). To investigate this effect, the transport of oxygen in CCL in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. The CCL was reconstructed as an agglomerated system. To explore the wettability effects, diffe...

The hydrophobic part of the solvent-accessible surface of a typical monomeric globular protein consists of a single, large interconnected region formed from faces of apolar atoms and constituting approximately 60% of the solvent-accessible surface area. Therefore, the direct delineation of the hydrophobic surface patches on an atom-wise basis is impossible. Experimental data indicate that, in a...

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...
