The problem of phase behaviour of solutions of globular proteins is approached by means of a Hard Core Yukawa fluid model with short-ranged attractions. We have determined the phase behaviour of this model system for different well widths, using a variety ...
We present a study of binary mixtures of eye lens crystallin proteins. A coarse-grained model of aqueous aand γ-crystallin mixtures based on molecular dynamics simulations and SANS experiments is proposed. Thermodynamic perturbation theory is implemented t ...
The contribution of the solvation energies to the assembly of polynuclear helicates reduces the free energy of intermetallic repulsion, DEMM, in condensed phase to such an extent that stable D3-symmetrical tetranuclear lanthanide-containing triplestranded ...
A thermodynamic model is developed for the precipitation of copper oxalate from aqueous solutions of copper nitrate and sodium oxalate in a small well-mixed batch reactor. This model is then used to explain the discrepancy between experimental pH evolution ...
The phase behavior of a DPPC monolayer on water was studied using vibrational sum-frequency spectroscopy (VSFG) in conjunction with fluorescence microscopy. A very sharp transition from a phase with curled alkyl chains to a phase with spatially extended ch ...
We discuss features of simple inter-particle potentials which are able to generate low-packing fraction arrested states, i.e. gels, in the absence of a macroscopic phase separation phenomenon. We suggest that the ratio between surface and bulk free energy ...
This work is devoted to the study of the analyticity properties of thermodynamic potentials (free energy, pressure) for classical lattice systems at low temperature. The central topic of our analysis, in this framework, is to show rigorously the absence of ...
Purpose: Assessment on enucleated pig eyes of a novel and minimally invasive method for the continuous monitoring of intraocular pressure (IOP), based on a novel wireless contact lens sensor (CLS). Methods: The wireless CLS is a disposable silicone soft co ...
Cataract is the leading cause of blindness worldwide. The clouding of the human eye lens is called "Grauer Star" in German. In the industrialized countries this process of increased blindness is corrected by the surgical removal of the clouded lens and its ...
Equilibrium phase diagrams in composition-conversion space have been calculated for stoichiometric blends of an epoxy resin with a diamine hardener and dendritic hyperbranched polymers, to which various numbers of epoxy groups have been grafted. An attempt ...
