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 ...
Experimental study of insulating properties and behaviour of thermal barrier coating systems in thermo cyclic conditions
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to improve the resistance of turbo jet engine parts exposed to high temperatures and overheating and sudden changes in temperature. For this purpose, three thermal barrier coating (TBC) systems ...
Development of Coated Electrodes with Solid Wire and Flux-Cored Alloyed Wire for Microalloyed Steel Welding
(MDPI, Basel, 2020)
In this paper, we will present our investigation of the quality of J55 microalloyed steel welds that were formed by a basic flux-cored wire electrodes that were of appropriate quality and alloyed with Ni and Mo. Based on ...
Optimization of Reactive Diluent for Bio-Based Unsaturated Polyester Resin: A Rheological and Thermomechanical Study
(Polymers, 2021)
Nowadays, unsaturated polyester resins (UPR) are mainly obtained from non-renewable resources. The ever-increasing regulations and the continuous demand for more sustainability have led to extensive research towards more ...
Removal of Nickel Ions from Aqueous Solutions by 2-Hydroxyethyl Acrylate/Itaconic Acid Hydrogels Optimized with Response Surface Methodology
(Gels, 2021)
The adsorption of Ni2+ ions from water solutions by using hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA) was studied. Hydrogel synthesis was optimized with response surface methodology (RSM). The ...
3D Printed Buccal Films for Prolonged-Release of Propranolol Hydrochloride: Development, Characterization and Bioavailability Prediction
(Pharmaceutics, 2021)
Gelatin-polyvinylpyrrolidone (PVP) and gelatin-poly(vinyl alcohol) (PVA) mucoadhesive buccal films loaded with propranolol hydrochloride (PRH) were prepared by semi-solid extrusion 3D printing. The aim of this study was ...
Removal of Estrone, 17 beta-Estradiol, and 17 alpha-Ethinylestradiol from Water by Adsorption onto Chemically Modified Activated Carbon Cloths
(Korean Fiber Soc, Seoul, 2020)
This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the ...
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 ...
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 ...
The chicken eggshell calcium oxide ultrasonically dispersed over lignite coal fly ash-based cancrinite zeolite support as a catalyst for biodiesel production
(Elsevier, 2021)
Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZMFA) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation ...
