The formation of twinned dendrites (feathery grains) in binary Al-Zn, Al-Mg, Al-Cu and Al-Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G approximate to 100 K cm(-1), v approximate to 1 mm s(-1), ...
The effects of particle reinforcement of Sn-4.0wt.%Ag-0.5wt.%Cu (SAC405) lead-free solder on interfacial intermetallic layer growth and strength of the ensuing joints through short-term isothermal aging (150 degrees C) were studied. Composite solders were ...
A phenomenological modelling approach has been developed to describe the massive transformation and the formation of lamellar microstructures during cooling in binary gamma titanium aluminides. The modelling approach is based on a combination of nucleation ...
We study phase separation in a deeply quenched colloid-polymer mixture in microgravity on the International Space Station using small-angle light scattering and direct imaging. We observe a clear crossover from early-stage spinodal decomposition to late-st ...
Three types of biomaterials based on hydroxyapatite are synthesized and investigated. Hydroxyapatite nanocrystals or microcrystals precipitated from low-temperature aqueous solutions serve as the initial material used for preparing spherical porous granule ...
Martensitic Ni-Ti was observed to transform to the austenitic phase due to defects introduced either by ion or electron irradiations at a temperature where the martensitic phase is normally stable. The phenomenon was studied by molecular dynamics simulatio ...
We numerically calculate the configurational entropy Sconf of a binary mixture of hard spheres, by using a perturbed Hamiltonian method trapping the system inside a given state, which requires fewer assumptions than the previous methods (Speedy 1998 Mol.Ph ...
Indicator displacement assays based on the organometallic complex [Cp*RhCl2]2 and the dye gallocyanine have been used to sense aminosugars and aminoglycosides in buffered aqueous solution by UV-Vis spectroscopy. The data of three assays at pH 7.0, 8.0 and ...
Single pan thermal analyses (SPTA) have been performed on Cu-14.5 wt.% Sn, Cu-21.3 wt.% Sri and Cu-26.8 wt.% Sit peritectic alloys. For this purpose, a SPTA assembly has been built and calibrated. As the latent heat is a function of temperature and composi ...
We discuss the static and dynamical properties of a model of short range attractive colloidal systems. Our model is a binary mixture of particles interacting with a modified Lennard-Jones potential that we simulated by molecular dynamics. As previously fou ...
