Thermal diffusivity of NTC lasers obtained by photoacoustic technique
(Emerald, 2004)
The thermal diffusivity of thick film NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) technique. The powder mixture was composed of MnO (60 percent), CoO (32 ...
Far Infrared Reflectivity Properties of BaTiO3 Ceramics
(Carl Hanser Verlag, 2001)
Far-infrared and infrared reflectivity measurements have been made on pure BaTiO3, BaTiO3 doped with 5 mol% LiF and (Ba,Ca,Pb)TiO3 at room temperature in the range between 50 and 1000 cm–1. A fitting procedure, based on a ...
A contribution to the knowledge of electrochemical deposition of W induced by Ni
(Elsevier Sequoia SA, 2000)
It was found that codeposition of Ni and W from an ammonia and citrate-containing electrolyte, is very sensitive to changes in operating conditions. The Ni-W alloy deposit exhibited sensitivity of chemical composition and ...
Influence of carriers on the capacitance of p-n junctions with deep donors
(Elsevier, 1974)
Applying the definition of p-n junction capacitance [1], which takes into account the effect of carriers in the space-charge region, a sufficiently accurate approximate expression is derived for the low-frequency capacitance ...
Green corrosion inhibitors of steel based on peptides and their constituents: a combination of experimental and computational approach
(Springer, 2023)
In this work, a tetrafunctional epoxy resin entitled 2,3,4,5-tetraglycidyloxy pentanal (TGP) was tested and investigated as a potential corrosion inhibitor for mild steel (MS) in 0.5 M H2SO4 solution. The corrosion inhibition ...
Degradation of tartrazine by Oxone® in the presence of cobalt based catalyst supported on pillared montmorillonite - Efficient technology even in extreme conditions
(Elsevier, 2023)
The catalytic degradation of hazardous organic contaminants in industrial wastewater is a promising technology. Reactions of tartrazine, the synthetic yellow azo dye, with Oxone® in the presence of catalyst in strong acidic ...
Formation of needle-like and honeycomb-like magnesium oxide/hydroxide structures by electrodeposition from magnesium nitrate melts
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
The processes of electrochemical deposition of magnesium oxide/hydroxide on glassy carbon (GC) electrode from magnesium nitrate hexahydrate melt have been investigated. A novel procedure predicting a possibility of direct ...
Electrodeposition of copper on glassy carbon and palladium from choline chloride - ethylene glycol deep eutectic solvent
(Elsevier, 2024)
Electrodeposition of copper from deep eutectic solvents (DES) based on a mixture of choline chloride and
ethylene glycol containing CuCl2⋅2H2O at 50 ◦C and 80 ◦C was studied. Electrochemical reduction/oxidation of
Cu(II)/Cu(0) ...
Radical chemistry, degradation mechanism and toxicity evolution of BPA in the UV/chlorine and UV/H2O2
(Elsevier BV, 2023)
UV-assisted advanced oxidation processes (AOPs) are widely used and studied in degradation of bisphenol A (BPA). However, detailed information on their radical chemistry and degradation mechanisms is still lacking. In this ...
Spatial distribution and source identification of heavy metals in European mountain beech forests soils
(Elsevier BV, 2022)
The main objectives of this research were to (i) investigate the concentration; (ii) characterize the distribution; (iii) determine the sources apportionment; (iv) estimate environmental and health risks of heavy metals ...
