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 ...
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 ...
Microstructural and cavitation erosion behavior of the cualni shape memory alloy
(MDPI, 2021)
Microstructural and cavitation erosion testing was carried out on Cu-12.8Al-4.1Ni (wt. %) shape memory alloy (SMA) samples produced by continuous casting followed by heat treatment consisting of solution annealing at 885◦ ...
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 ...
Implementation of the Chicot–Lesage Composite Hardness Model in a Determination of Absolute Hardness of Copper Coatings Obtained by the Electrodeposition Processes
(MDPI, 2021)
The influence of various electrolysis parameters, such as the type of cathode, composition of the electrolyte and electrolysis time, on the morphology, structure and hardness of copper coatings has been investigated. ...
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 ...
Synthesis, Characterization, and Cytotoxicity of a Novel Gold(III) Complex with O,O-Diethyl Ester of Ethylenediamine-N,N-Di-2-(4-Methyl)Pentanoic Acid
(MDPI, 2016)
A novel gold(III) complex, [AuCl2{(S,S)-Et(2)eddl}]PF6, ((S,S)-Et(2)eddl = O,O-diethyl ester of ethylenediamine-N,N-di-2-(4-methyl)pentanoic acid) was synthesized and characterized by IR, 1D (H-1 and C-13), and 2D (H,H-COSY ...
Electrorefining process of the non-commercial copper anodes
(MDPI, 2021)
The electrorefining process of the non-commercial Cu anodes was tested on the enlarged laboratory equipment over 72 h. Cu anodes with Ni content of 5 or 10 wt.% and total content of Pb, Sn, and Sb of about 1.5 wt.% were ...
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 ...
Structural and electrochemical properties of nesting and core/shell pt/tio2 spherical particles synthesized by ultrasonic spray pyrolysis
(MDPI, 2020)
Pt/TiO2 composites were synthesized by single-step ultrasonic spray pyrolysis (USP) at different temperatures. In an in-situ method, Pt and TiO2 particles were generated from tetra-n-butyl orthotitanate and chloroplatinic ...
