We have applied density functional methods to predict the nucleation rates of bubbles in superheated, stretched, or supersaturated binary fluid mixtures. Our model uses Lennard-Jones mixtures, with mixing rules chosen to allow either ideal or nonideal solution behavior. Deviations from the predictions of classical nucleation theory are in general quite large, with the locus of observable bubble...
We conducted reversed deliquescence experiments in saturated NaCl–NaNO3 – H2O, KNO3 – NaNO3 – H2O, and NaCl–KNO3 – H2O systems from 90 to 120 °C as a function of relative humidity and solution composition. NaCl, NaNO3 , and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository e...
The laws of conservation of mass, momentum, and energy are applied to the compressible flow through a two-dimensional cascade of airfoils. A fundamental relation between the ultimate upstream and downstream flow angles, the inlet Mach number, and the pressure ratio across the cascade is derived. Comparison with the corresponding relation for incompressible flow shows large differences. The fund...
We reported recently that certain β(3) -peptides self-assemble in aqueous solution into discrete bundles of unique structure and defined stoichiometry. The first β-peptide bundle reported was the octameric Zwit-1F, whose fold is characterized by a well-packed, leucine-rich core and a salt-bridge-rich surface. Close inspection of the Zwit-1F structure revealed four nonideal interhelical salt-bri...
