An equation of state for associating liquids is presented as a sum of three Helmholtz energy terms: Lennard-Lones (LJ) segment (temperature-dependent hard sphere + dispersion), chain (increment due to chain formation), and association (increment due to association). This equation of state has been developed by extending Wertheim's theory obtained from a(More)
This contribution describes an experimentally straightforward procedure for preparing and screening surfaces for their ability to resist the adsorption of proteins from solution. For brevity, we call surfaces " protein resistant " when they are resistant to the adsorption of proteins from solution. We have used this procedure to identify several functional(More)
Recently, we devised an energy scale to vary systematically amino-acid residue-solvent interactions for Monte Carlo simulations of lattice-model proteins in water. For 27-mer proteins, the folding behavior varies appreciably with the choice of interaction parameters. We now perform similar simulations with 64-mers to study the size dependence of the optimal(More)
Fundamental studies of enzyme-solvent interactions can be conducted with supercritical fluids because small changes in pressure or temperature may bring about great changes in the properties of a single solvent near its critical point. Cholesterol oxidase is active in supercritical carbon dioxide and supercritical carbon dioxide-cosolvent mixtures.(More)
Pretreatment of miscanthus is essential for efficient enzymatic production of cellulosic ethanol. This study reports a possible pretreatment method for miscant-hus using aqueous ethylenediamine (EDA) for 30 min at 180 °C with or without ammonia. The mass ratio of mis-canthus to EDA was varied from 1:3, 1:1, and 1:0.5, keeping the mass ratio of miscanthus to(More)

for the use of their facilities. The use of microwave power in the heating of solids in a packed bed results in a uniform temperature throughout the bed, almost instantaneously. Thus, heat transfer through the particle-particle mode between the pellets was eliminated and fluid-particle heat transfer coefficients alone were determined experimentally. Eight(More)
