โœฆ Synopsis

Nuclear magnetic resonance water proton spin-spin relaxation time T(2) was measured in wood samples with moisture contents ranging from 0.50 to 26.4%. The experimental results are discussed in terms of Monte Carlo simulations, which determine the correlation times tau for reorientation of the water molecule proton-proton vectors. We demonstrate that 1/T(2) and tau qualitatively follow the same behavior with surface hydration. The common application of the multisite exchange model to hydrated systems is discussed in light of the new results.

Adsorption of proteins occurs via diffusion toward the interface, actual adsorption, and subsequent irreversible conformational changes resulting in denaturation of the native protein structure. The conventional kinetic models describing these steps are based on the assumption that the denaturation

## Abstract The adsorption of asymmetrical triblock copolymers from a nonโ€selective solvent on solid surface has been studied by using Scheutjensโ€Fleer meanโ€field theory and Monte Carlo simulation method on lattice model. The main aim of this paper is to provide detailed computer simulation data, t
