We investigate the diffusion of particles on heterogeneous lattices with two kinds of nonequivalent sites. General analytical expressions for the chemical and jump diffusion coefficients have been derived in the case of strong inhomogeneity. We have calculated coverage dependencies of the diffusion coefficients and other necessary thermodynamic quantities for some representative values of the l...

An Extended Ruckel (E. H.) calculation was performed for the energy of Fex clusters (with x = 9, 10, 13, 15, 18) that are used to model the 111, 100, 110 surface planes of an iron single-crystal. Interaction energies of atomic and molecular nitrogen with each cluster were calculated for different geometrical configurations of the system. From this data thermodynamic and kinetic considerations a...

A generalized kinetic model for fly ash native carbon oxidation is developed. It is shown that the conversion of fly ash native carbon to CO2 is the result of two simultaneous processes taking place on fly ash surface: the first process (rate constant k2) is the direct oxygen transfer from a metal oxide site to a vacant carbon active site leading to immediate carbon gasification; the second one...

The newly identified tripartite motif (TRIM) family of proteins mediate innate immunity and other critical cellular functions. Here we show that TRIM21, which mediates the autoimmune diseases rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's syndrome, is a previously undescribed IgG receptor with a binding mechanism unlike known mammalian Fcgamma receptors. TRIM21 simultaneously...

Microarray analysis has become increasingly complex due to the growing size of arrays and the inherent cross-binding of targets. In this work, we explore the effects of matched and mismatched target species concentrations, temperature, and the time of hybridization on sensing specificity in two-component systems. A finite element software is used to simulate the diffusion of DNA through a micro...

A theoretical formulation is developed for the activated kinetics when some subset of nuclear modes of the thermal bath is slower than the reaction and ergodicity of the thermal bath is not maintained. Nonergodic free energy profiles along the reaction coordinate are constructed by using restricted canonical ensembles with the phase space available to the system found by solving a self-consiste...

Lytic polysaccharide monooxygenases (LPMOs) consist of a class enzymes that boost the release oxidised products from plant biomass, in an approach is more eco-friendly than traditional ones, employing harsh chemicals. Since LPMOs are redox enzymes, they could possibly be exploited by immobilisation on electrode surfaces. Such requires knowledge kinetic and thermodynamic information for interact...
