Application of the Composite Hardness Models in the Analysis of Mechanical Characteristics of Electrolytically Deposited Copper Coatings: The Effect of the Type of Substrate
(Metals, 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 ...
Exposure Factors in Health Risk Assessment of Heavy Metal(loid)s in Soil and Sediment
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Heavy metal(loid)s (HMs) play an important role in economic development since they are used in various branches of industry. However, all industrial activities emit HMs into the environment, where they are no longer useful ...
Fast Gold Recovery from Aqueous Solutions and Assessment of Antimicrobial Activities of Novel Gold Composite
(MDPI, 2023)
A novel porous gold polymer composite was prepared by the functionalization of a glycidyl methacrylate-based copolymer (pGME) with ethylene diamine (pGME-en), and activation by gold (pGME-en/Au), in a simple batch adsorption ...
Mechanical Properties of Electrolytically Produced Copper Coatings Reinforced with Pigment Particles
(MDPI, 2023)
Copper from sulfate baths without and with added inorganic pigment particles based on strontium aluminate doped with europium and dysprosium (SrAl2O4: Eu2+, Dy3+) was electrodeposited on a brass cathode by a galvanostatic ...
Hydrometallurgical Process for Selective Metals Recovery from Waste-Printed Circuit Boards
(MDPI, Basel, 2018)
This paper presents an experimentally-proved hydrometallurgical process for selective metals recovery from the waste-printed circuit boards (WPCBs) using a combination of conventional and time-saving methods: leaching, ...
Kinetics of Chalcopyrite Leaching by Hydrogen Peroxide in Sulfuric Acid
(MDPI, Basel, 2019)
In ores, chalcopyrite is usually associated with other sulfide minerals, such as sphalerite, galena, and pyrite, in a dispersed form, with complex mineralogical structures. Concentrates obtained by flotation of such ores ...
Selenate adsorption from water using the hydrous iron oxide-impregnated hybrid polymer
(MDPI, Basel, 2020)
Hybrid adsorbent, based on the cross-linked copolymer impregnated with hydrous iron oxide, was applied for the first time for Se(VI) adsorption from water. The influence of the initial solution pH, selenate concentration ...
Structure and Strength of Isothermally Heat-Treated Medium Carbon Ti-V Microalloyed Steel
(Metals, 2021)
Isothermal transformation characteristics of a medium carbon Ti-V microalloyed steel were investigated using light microscopy, scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS), and by ...
Advances in Thermochemical Synthesis and Characterization of the Prepared Copper/Alumina Nanocomposites
(MDPI, Basel, 2020)
This paper presents thermochemical synthesis of copper/alumina nanocomposites in a Cu-Al(2)O(3)system with 1-2.5 wt.% of alumina and their characterization, which included: transmission electron microscopy: focused ion ...
Implementation of the Chicot-Lesage Composite Hardness Model in a Determination of Absolute Hardness of Copper Coatings Obtained by the Electrodeposition Processes
(Metals, 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. ...
