This contribution presents results on the parameter estimation of rate constants and optical response factors in a reduced order surface kinetics ~ROSK! model, which has been developed to describe the decomposition kinetics of the organometallic precursors involved and their incorporation into the film deposition. As a real-time characterization technique, we applied p-polarized reflectance spe...

abstractbackground and objectives:the phosphorus is second limiting nutrient in soil for crop production after nitrogen. mobility and availability of phosphorus (p) in soils is affected by phosphorus desorption characteristics. information about the effect of organic matter on kinetics and thermodynamics of p desorption in calcareous soils of east azerbaijan province is limited. the objective o...

Polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) in combination with electrochemistry, was employed to study the influence of surface charge (potential) on the kinetics of bovine serum albumin (BSA) adsorption on a biomedical-grade 316LVM stainless steel surface is discussed. The BSA adsorption kinetics was found to greatly depend on the surface potential. With an ...

Attaining fast oxygen exchange kinetics on perovskite and related mixed ionic and electronic conducting oxides is critical for enabling their applications in electrochemical energy conversion systems. This study focuses on understanding the relationship between surface chemistry and the surface oxygen exchange kinetics on epitaxial films made of (La1−xSrx)2CoO4, a prototypical Ruddlesden−Popper...

this study assesses the kinetics of hydration of pulverised fuel ash and metakaolin cement pastes and compares how the rate of reaction affects the pore-characteristics and resistance to ionic ingress. the degrees of hydration for the different mixtures were evaluated, both as a function of the calcium hydroxide content and with respect to the chemically combined water contents. the reaction ra...

The article presents the relevance of development new technologies and formulations food products with a foamy structure. kinetics moisture sorption fruits vegetables subjected to hydrothermal mechanical processing at various partial vapor pressures in environment has been studied. Calculations hygroscopic characteristics fruit vegetable stabilizers have made. Such parameters monolayer as conce...

In the present study, we developed an assay of interactions of daptomycin with four model lipid membranes that mimicked mammal cell membranes and gram-positive and negative bacteria membranes. We also analyzed the binding kinetics of the gram-positive bacteria membranes using surface plasmon resonance (SPR). Daptomycin showed a higher affinity for the model gram-positive bacteria membrane than ...

We derive the equations that describe adsorption of diffusing particles onto a surface followed by additional surface kinetic steps before being transported across the interface. Multistage surface kinetics occurs during membrane protein insertion, cell signaling, and the infection of cells by virus particles. For example, viral entry into healthy cells is possible only after a series of recept...
