Influence of the Shape of Copper Powder Particles on the Crystal Structure and Some Decisive Characteristics of the Metal Powders
(MDPI, 2019)
Three different forms of Cu powder particles obtained by either galvanostatic electrolysis or a non-electrolytic method were analyzed by a scanning electron microscope (SEM), X-ray diffraction (XRD) and particle size ...
Influence of Parameters and Regimes of the Electrodeposition on Hardness of Copper Coatings
(MDPI, 2023)
Correlation among morphological, structural and hardness characteristics of electrodeposited
copper coatings is presented in this review paper. Cu coatings were produced applying constant galvanostatic (DC) and pulsating ...
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, ...
Comparative Morphological and Crystallographic Analysis of Electrochemically- and Chemically-Produced Silver Powder Particles
(MDPI, 2017)
Silver powders chemically synthesized by reduction with hydrazine and those produced by electrolysis from the basic ( nitrate) and complex ( ammonium) electrolytes were examined by X-ray diffraction (XRD) and scanning ...
Correlation of Morphology and Crystal Structure of Metal Powders Produced by Electrolysis Processes
(MDPI, 2021)
In this review paper, morphologies of metal powders produced by the constant (potentiostatic
and galvanostatic) regimes of electrolysis from aqueous electrolytes are correlated with
their crystal structure at the ...
Magnesium-Gold Alloy Formation by Underpotential Deposition of Magnesium onto Gold from Nitrate Melts
(MDPI, 2017)
Magnesium underpotential deposition on gold electrodes from magnesium nitrate-ammonium nitrate melts has been investigated. Linear sweep voltammetry and potential step were used as electrochemical techniques. Scanning ...
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 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 ...
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 ...
Recovery of Rare Earth Elements from Spent NdFeB Magnets: Metal Extraction by Molten Salt Electrolysis (Third Part)
(MDPI, 2023)
The results obtained from the work on a concept of a recycling process for NdFeB magnets
to recover rare earth elements for remanufacturing similar magnets are presented. This paper
investigates the viability of extracting ...
