Copper doped silica glass with nominal composition 10Cu (mol%)–90SiO2 (mol%) is prepared using the sol–gel method. The dc conductivities are Arrhenius temperature dependent with activation energy 1.0 eV. The conducting species is attributed to th

We have used the isothermal electric resistance relaxation to investigate the variation of microstructure and oxygen diffusion behaviour in melt-texture grown (MTG) YBCO bulk. Post-annealing below 550 °C for an as-grown sample does not seriously inf

Cu2ZnSn(S,Se)4 (CZTSSe) thin films were prepared on molybdenum foil substrate by sol–gel method. The effects of selenization temperature on the properties of CZTSSe thin films and CZTSSe/Mo interfaces were studied. The phase structures, elemental c

Solid electrolytes-based lithium phosphates have achieved a great evolution due to the safety problem in the lithium-ion battery. This work targets to investigate the prepared glasses within the 20Li2O–(50 − x)Li2WO4–xTiO2–30P2O5 system, with

Vapor pressure measurements, in terms of a (non-)isothermal isopiestic method, were carried out in the system Cd-Pr between 749 K and 1067 K (476 °C and 794 °C). Thermodynamic activities of cadmium as a function of temperature were obtained directl

Crystalline silicon samples (with or without their native oxide layer) have been submitted to intense optical irradiations generated by laser sources delivering pulses of different durations (in the ns or μs regimes) in the visible (≈ 550 nm) or i

By varying the molar water alkoxide ratios R, (0.5 ≤ R ≤ 1.75), the progressive hydrolysis and polycondensation of tetraethoxysilane (TEOS) in acidic medium (HCl 0.03 M) were investigated. In order to appreciate the effects of the alcohol on the

Alloys of nickel and zinc are used for the hot dip galvanizing of reactive steels containing around 0.1 pct Si. The production of these alloys is hindered by the low solubility of nickel in molten zinc at normal zinc alloying temperatures (450 °C to

The phonon mode(s) controlling the multiphonon relaxation (MPR) in PbO-Bi 2 O 3 -Ga 2 O 3 glass was analyzed, and the effect of GeO 2 addition on the MPR process was investigated. MPR rates were obtained from the lifetimes of the Tm 3+ : 3 H 4 level

International audience; The Kolmogorov’s 4/5 law is often considered as the sole exact relationship of inertial range statistics. Its asymptotic character, however, has been evidenced, investigating the finite Reynolds number (FRN) effect for the t
