Thermal stability of a supersaturated Fe-Ge-Nb solid solution produced by ball milling
(Institute of Physics Publishing (IOP), 2010)
Thermal evolution of Fe neighbourhood in a supersaturated bcc Fe(Ge,Nb) solid solution, obtained as the final product of mechanical alloying of Fe75Ge20Nb5, was studied. No changes in Fe neighbourhood were detected after ...

Removal of basic yellow cationic dye by an aqueous dispersion of Moroccan stevensite
(Elsevier, 2013)
The aim of this study was to investigate the adsorption of basic yellow, a cationic dye, from aqueous solution by natural stevensite, with 104m2/g of specific surface area. The kinetics and the effects of several experimental ...

Evidence of nanograin cluster coalescence in spark plasma sintered α-Al2O3
(Elsevier, 2013)
The aim of this study is to elucidate the coarsening kinetics involved during densification of fine-grained pure α-alumina by spark plasma sintering. Low temperature and short dwell time sintering conditions were used to ...

Premelting of ice adsorbed on a rock surface
(Royal Society of Chemistry, 2020-05-28)
Considering ice-premelting on a quartz rock surface (i.e. silica) we calculate the Lifshitz excess pressures in a four layer system with rock-ice-water-air. Our calculations give excess pressures across (1) ice layer, (2) ...
