Effects of ionic strength and surface charge on protein adsorption at PEGylated surfaces

Article Abstract:

The study aims at an improved understanding of the mechanisms of protein resistance of poly ethylene glycol (PEG) layers, using the combcraft-copolymer poly(L-Iysine)-g-poly(ethylene glycol) (PLL-g-PEG), and concerns the effects of systematic variations in the surface properties, in particular PEG chain length and density, and surface charge. The combination of atomic force microscopy surface force measurements and protein adsorption experiment provides insights into the interfacial forces associated with various PEGylated surfaces and the mechanisms of protein resistance.

Study of gamma-alumina-supported hydrotreating catalyst: I. Adsorption of bare MoS(sub 2) sheets on gamma-alumina surfaces

Article Abstract:

The adsorption of bare MoS(sub 2) sheets was studied where no promoter was considered. A periodical FW-DPT approach that makes use of crystal periodic boundary conditions and symmetry, and consequently, and that better describes the two systems and their interactions is proposed.

Thermal evolution of hydrogen following adsorption of defective UO2 (100)

Article Abstract:

Temperature programmed desorption has been used to study the evolution of molecular hydrogen from UO2 (100) surfaces exposed to water vapor. The defects created during ion sputtering represent an important channel in radiation chemistry.
