A mathematical model is presented that investigates the diffusive reequilibratrion of chemical species in melt inclusions with external melt through the host crystal. Analytic solution of the differential equations reveals that reequilibration is easier (1) for species with higher diffusivities in the host crystal, (2…
The measurement of the saddle-splay surface elastic constant ${\mathit{K}}_{24}$ in a nematic liquid crystal is reported based on two independent deuterium nuclear-magnetic-resonance ${(}^{2}$H-NMR) experiments. Fifty years after the pioneering work of Oseen and Zocher, these measurements were made from observations o…
Optical-quality transparent conducting films of polyaniline (PANI) and of conducting polyblends of polyaniline with amorphous bulk polymers are described. Using functionalized protonic acids to induce solubility in common organic solvents, PANI and PANI polyblends can be cast from solution, in the conducting form, ont…
A high-precision solution structure of the elastase inhibitor eglin c was determined by NMR and distance geometry calculations. A large set of 947 nuclear Overhauser (NOE) distance constraints was identified, 417 of which were quantified from two-dimensional NOE spectra at short mixing times. In addition, a large numb…
Carbon thin films have been prepared by 248 nm excimer laser vaporization of graphite targets. The effect of a variety of process parameters on the film properties is investigated. Deposition at or below room temperature yields diamond-like films with low hydrogen content, high optical transmission, and high resistivi…
Cement pastes reinforced with glassfibre, popularly called GRC ("Glassfibre Reinforced Cements") are compound materials which have been widely used in the construction field for the last 30 years. Their good mechanical properties, lightness and resistance to corrosion and fire make them suitable in the process of repl…
The electrochemical process of steel corrosion in concrete are studied by simulating its liquid phase with synthetical solutions in a large range of hydroxyls, carbonates and chlorides ions.The steel specimen is either under or without an electrical polarization. The present analysis has made it possible to define a n…
