We report the qualitative study of the influence of both elastic compliances and higher order terms of Landau free energy potential on the phase diagram of Pb(Zr0.5Ti0.5)O-3 thin films by using a single domain Landau theory. Although the impact of elastic ...
In this contribution I summarize our research on the formation of nanoparticles embedded in a-SiO2-x matrices. In particular, I focus on the Si diffusion in SiO2-x matrices, and amorphous-to-crystalline phase transition in Si nanoparticles embedded in SiO2 ...
Iodine added to iodide-based ionic liquids leads to dramatic changes of their physical properties which may have implications for technological applications. Here we study the phase diagram of 1-methyl 3-propylimidazolium iodide, the temperature versus iod ...
Amorphous nanoparticles (a-NPs) have physicochemical properties distinctly different from those of the corresponding bulk crystals; for example, their solubility is much higher. However, many materials have a high propensity to crystallize and are difficul ...

Kinetic models have been demonstrated to be useful in on-line batch monitoring systems. The ability to monitor a reaction in real time is invaluable to the production process of industrial and pharmaceutical products. However, it is not a commonly used tec ...
The rigidity temperature of a solidifying alloy is the temperature at which the solid plus liquid phases are sufficiently coalesced to transmit long range tensile strains and stresses. It determines the point at which thermally induced deformations start t ...
Slurries are widely used in important chemical and pharmaceutical manufacturing processes. In this presentation we report chemical monitoring and modeling of batch slurry reactions using optical and calorimetric measurement where key analytes are present i ...
An attempt has been made to achieve the crystallization of silicon thin film on metallic foils by long pulse duration excimer laser processing. Amorphous silicon thin films (100 nm) were deposited by radiofrequency magnetron sputtering on a commercial meta ...
Strain response of polycrystalline barium titanate (BaTiO3) was investigated under high unipolar electric field (0 to 4 kV/mm) and compressive stress (0 to 400 MPa) in the temperature range from 25 to 160 degrees C. In the vicinity of the Curie point (T-C) ...
Phase change materials are of great interest as active layers in rewritable optical disks and novel electronic nonvolatile memories. These applications rest on a fast and reversible transformation between the amorphous and crystalline phases upon heating, ...
