Influence of Rare Earth Oxide Concentration on Electrochemical Co-Deposition of Nd and Pr from NdF3-PrF3-LiF Based Melts
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
The impact of rare earth oxide (REO) concentration on the deposition process and selective recovery of the metal being deposited from a molten fluoride salt system was investigated by applying deposition of Nd and Pr and ...
Characterization of Defined Pt Particles Prepared by Ultrasonic Spray Pyrolysis for One-Step Synthesis of Supported ORR Composite Catalysts
(MDPI, 2022)
Polygonal Pt nanoparticles were synthesized using ultrasonic spray pyrolysis (USP) at different precursor concentrations. Physicochemical analysis of the synthesized Pt particles involved thermogravimetric, microscopic, ...
Electrochemical study of Nd and Pr co-deposition onto Mo and W from molten oxyfluorides
(MDPI, 2021)
Electrodeposition processes of neodymium and praseodymium in molten NdF3 + PrF3 + LiF + 1 wt.%Pr6O11 + 1 wt.%Nd2O3 and NdF3 + PrF3 + LiF + 2 wt.%Pr6O11 + 2 wt.%Nd2O3 electrolytes at 1323 K were investigated. Cyclic ...
Electrochemical Investigation of Lateritic Ore Leaching Solutions for Ni and Co Ions Extraction
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Determination of the extractive behavior of ionic species from lateritic ore leachates is complex, since the leachates are pregnant with tens of different ions in, as a rule, multiple oxide states. To examine the possible ...
Application of the Composite Hardness Models in the Analysis of Mechanical Characteristics of Electrolytically Deposited Copper Coatings: The Effect of the Type of Substrate
(MDPI, 2021)
The mechanical characteristics of electrochemically deposited copper coatings have been
examined by application of two hardness composite models: the Chicot-Lesage (C-L) and the Cheng-Gao (C-G) models. The 10, 20, 40 and ...
Spray-pyrolytic tunable structures of mn oxides-based composites for electrocatalytic activity improvement in oxygen reduction
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Hybrid nanomaterials based on manganese, cobalt, and lanthanum oxides of different morphology and phase compositions were prepared using a facile single-step ultrasonic spray pyrolysis (USP) process and tested as ...
Morphology and Structure of Electrolytically Synthesized Tin Dendritic Nanostructures
(MDPI, 2022)

Morphology, Structure and Mechanical Properties of Copper Coatings Electrodeposited by Pulsating Current (PC) Regime on Si(111)
(MDPI, 2020)
Copper electrodeposition on (111)-oriented Si substrate was performed by the pulsating current (PC) regime at various average current densities in the range of 15–70 mA·cm−2, obtained by varying either the frequency (30, ...
Electrodeposition of Aluminium-Vanadium Alloys from Chloroaluminate Based Molten Salt Containing Vanadium Ions
(MDPI, 2021)
The Al-V alloys were synthetized by potentiostatic electrodeposition onto a glassy carbon electrode from equimolar AlCl3 + NaCl bath containing vanadium ions at 200 °C. The alloy deposits were characterized by X-ray ...
Recovery of vanadium (V) oxyanions by a magnetic macroporous copolymer nanocomposite sorbent
(MDPI, 2021)
An amino‐functionalized magnetic macroporous copolymer of glycidyl methacrylate (GM) and ethylene glycol (E) dimethacrylate (m‐poly(GME)‐deta) was synthesized, fully characterized, and used to investigate the adsorption ...
