Theoretical Study of the Adsorption of Halogens on GaAs Surfaces

The structure and properties of absorbed fluorine and chlorine atoms on GaAs surfaces are investigated. The energies of surface species' localized vibrations are determined. Our results show that localized As±Cl and Ga±Cl valence vibrations occur in the 40 and 50 meV regimes, respectively, while As±F and Ga±F vibrations are found in the 90 and 80 meV regimes, respectively. Comparisons are made ...

Theoretical study of n-alkane adsorption on metal surfaces

study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

Polyelectrolyte adsorption on solid surfaces: theoretical predictions and experimental measurements.

This work utilizes a combination of theory and experiments to explore the adsorption of two different cationic polyelectrolytes onto oppositely charged silica surfaces at pH 9. Both polymers, poly(diallyldimethylammonium chloride), PDADMAC, and poly(4-vinyl N-methylpyridinium iodide), PVNP, are highly charged and highly soluble in water. Another important aspect is that a silica surface carries...
