In the presence of F2 overpressure, at elevated temperature, and despite similarity their crystal structures, CuF2 AgF2 unexpectedly form two distinct solid solutions, (Cu1−xAgx)F2 (Ag1−xCux)F2. Each phase shows different mutual solubility Cu2+ Ag2+ (shown as yellow violet balls), magnetic properties are strongly impacted by this seemingly simple isoelectronic substitution. More information can...

the purpose of this study was to investigate the deposition of the hydroxyapatite (ha) coating via the electrophoresis procedure. the ha deposition was performed in an ethanol, methanol, acetone and isopropanol suspension. methanol was found to be the best deposition media. among the different environmental conditions, including the encapsulation of the samples under two vacuum types of pressur...

asphaltene precipitation and deposition is a serious problem in many iranian fields. the deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil production. this paper studies the asphaltene problem and mitigation methods in wellstring systematically. it presents new approach based on the combination of thermodynamic modeling o...

the suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. a feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. physical vapor deposition (pvd) and pulsed plasma-enhanced chemical vapor deposition (pecvd), naturally, form asymmetric na...

Jing Wu et al. have synthesized enantiomerically pure secondary alcohols under mild reaction conditions. The stereospecific alcohols, formed by the hydrosilylation of prochiral ketones, are intermediates in the manufacturing of industrial compounds and pharmaceuticals. Previous methods for creating the alcohols have been hampered by the high cost of metal catalysts, low substrate-to-catalyst ra...
