The onset of cavitation is strongly enhanced by the presence of rough surfaces or impurities in the liquid. Despite decades of research, the way the geometry of these defects promote the nucleation of bubbles and its effect on the kinetics of the process r ...
Phase equilibria in the CaO-Al2O3-Fe2O3-SO3 system have been studied, mainly at 1325 degrees C. In particular the solid solution compositions of ye'elimite Ca-4(Al6O12)SO4 and brownmillerite (C-2(A,F)) phases have been analysed and used to estimate the com ...
Thermodynamic modeling is a versatile tool for predicting the chemical composition cement during the hydration of cement. The quality of the thermodynamic modeling depends directly on the quality and completeness of thermodynamic database used. One of the ...
An article made of an alloy of the general formula Pt1-a-bMa(B1-xMdx)b in which i) M stands for one or a mixture of metallic element(s) of the group Zr, Ti, Fe, Ni, Co, Cu, Pd, Ag, Al ii) Md stands for one or a mixture of several metalloids of the group Si ...
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 ...

A long lasting controversy on the nature of the reaction between liquid, Al and Al45Cr7 has been ended by planar front solidification experiments of Al-Cr alloy in a Bridgman furnace. Cr depletion in the liquid ahead of the quenched planar interface proves ...
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 ...
The modelling platform mu ic [1] has been used to investigate the mechanisms occurring during the hydration of alite. It is shown that it is possible to obtain a good simulation of the hydration kinetics through the implementation of two mechanisms: a diss ...
The enthalpies of formation of the intermetallic compounds in the Ge-Ni binary system have been determined by calorimetric measurement and first-principles calculations. Based on the results obtained and information available in the literature, the phase d ...
The properties of the interface between solid and melt are key to solidification and melting, as the interfacial free energy introduces a kinetic barrier to phase transitions. This makes solidification happen below the melting temperature, in out-of-equili ...
