Kinetic model of adsorption on crystal surfaces

Nickelocene adsorption on single-crystal surfaces

Energetics of hydrogen coverage on group VIII transition metal surfaces and a kinetic model for adsorption/desorption.

We determined the binding energy of hydrogen to the closest packed surface for all nine group VIII transition metals as a function of surface coverage using quantum mechanics (density functional theory with the generalized gradient approximation) with periodic boundary conditions. The study provides a systematic comparison of the most stable surfaces of the nine group VIII transition metals, le...

Excess adsorption of biomolecules on soft surfaces: Adsorption of DNA, proteins and lactose on fatty surfaces

Insoluble fatty surfaces are involved in many important interactions such as in biomembranes with soluble biological macro and micromolecules. In this paper we have studied the adsorption interaction of aqueous solution of DNA, some proteins and lactose on several sparingly soluble fatty substances namely milk fat, stearic acid, palmitic acid, phosphatidyl choline and cholesterol surfaces by me...

Protein adsorption on nanostructured implant surfaces: A model calculation for the prediction of preferred adsorption sites

Introduction Adsorption of proteins at a solid-liquid interface is an important phenomenon in biology and highly relevant for the design of biocompatible materials. It is well-known that protein adsorption is one of the first events which take place when a foreign material comes into contact with a living body and is believed to be a key factor in controlling subsequent cellular adhesion. In th...

Gas adsorption on quasicrystalline surfaces

The low-friction properties of quasicrystal surfaces suggest their use as coatings on moving machine parts, including those in internal combustion engines. In such applications, additional lubricants are typically used. Since the low-friction properties of quasicrystals are thought to depend on their aperiodic structures, the interactions of lubricants on quasicrystalline surfaces may have an i...
