This work describes the synthesis as well as the photophysical and mesomorphic properties of new luminescent liquid crystals able to emit narrow bands in the visible range, and featuring lanthanide ions incorporated into pro-mesogenic coronands. In order t ...
The charge "belonging" to a given atom in a condensed system is not a measurable quantity, and can be defined only by means of some arbitrary model and/or theory: the static dipole (or multipole) associated with a given molecule in a molecular solid or liq ...
We discuss the phase behaviour of spherical hard-core particles, with an attractive potential, as described by a hard-core Yukawa model. The ratio of the range of the attraction to the diameter of the particles is an important control parameter of the prob ...
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 ...
Ozonation membrane contact was carried out with a tubular membrane module to study the effects of the flow rates and the temperatures of the liquid phase on ozone transfer and on the enhancement of mass fluxes. Changes in liquid temperature gave both posit ...
A multiphase-field model for the description of coalescence in a binary alloy is solved numerically using adaptive finite elements with high aspect ratio. The unknown of the multiphase-field model are the three phase fields (solid phase 1, solid phase 2, a ...
Important reductions of refrigerant amounts can be achieved by using secondary refrigeration fluids. Ice slurry is a two-phase fluid and thus, compared to single phase secondary refrigeration fluids, offers the advantage of the latent heat of fusion when t ...
We have modeled the decomposition of nonstoichiometric amorphous SiOx upon annealing into silicon and stoichiometric silica, using a new method based on mapping Metropolis Monte Carlo simulations onto rate equations. The concentrations of all oxidation sta ...
HMT-C11 belongs to the family of adducts formed by the cocrystallization of N-4(CH2)(6) molecules ( hexamethylenetetramine or HMT) and aliphatic dicarboxylic acids HOOC(CH2)(n-2)COOH with 5 less than or equal to n less than or equal to 13 (Cn). The adducts ...
The single-crystal investigation of the self-hosting sigma-structure of beta-tantalum (beta-Ta) at 120 K (low-temperature, LT, structure) and at 293 K (RT-I before cooling and RT-II after cooling and rewarming; RT represents room temperature) shows that th ...
