Preparation and Characterization of Geopolymers Based on Metakaolin with the Addition of Organic Phase PVA
(MDPI, 2023)
Geopolymers have excellent physical and mechanical properties, so they can be used as a substitute for ordinary polymers. Geopolymers are ceramic materials, which exhibit the property of brittleness, which can be a limitation ...
Indium Recovery from Jarosite Pb–Ag Tailings Waste (Part 1)
(MDPI, 2023)
The processing of zinc ore using hydrometallurgical methods leads to the formation and accumulation of a by-product called jarosite, which contains concentrated precious metals. In this study, we propose the recovery of ...
Ability of Deep Eutectic Solvent Modified Oat Straw for Cu(II), Zn(II), and Se(IV) Ions Removal
(MDPI, 2023)
In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the ...
Effect of the Deposition of Vanadium-Oxide on the Photocatalytic Activity of TiO2 Nanotubes and Its Photodiode Performance Interfaced with CH3NH3PbI3 Single Crystal
(MDPI, 2023)
In this study, we report the influence of vanadium oxide (VO), as a photosensitive component, on the photoactivity of TiO2 nanotubes (TNTs). A series of TNTs of varying tube diameter were synthesized by the anodization of ...
Structure-Dependent Electrochemical Behavior of 2-Pyridone Derivatives: A Combined Experimental and Theoretical Study
(MDPI, 2023)
In this work, the electrooxidation ability of nine pyridones was evaluated using cyclic(CV) and square-wave voltammetry (SWV) in Britton–Robinson (BR) aqueous buffer solutions on aglassy carbon electrode (GC). The dependence ...
Foam glasses made from green bottle glass and sugar beet factory lime as a foaming agent
(Elsevier Ltd., 2023)
Great waste production alongside limited natural resources represents huge environmental and economic problems worldwide. Sustainable waste management and industrial production can reduce pollution and gain some economic ...
Studies of Clinoptilolite-Rich Zeolitic Tuffs from Different Regions and Their Activity in Photodegradation of Methylene Blue
(MDPI, 2022)
The present study focuses on clinoptilolite (CLI)-rich natural zeolitic tuffs and their photocatalytic activity in the degradation of cationic organic dyes. CLI from different regions was tested in the photocatalytic ...
Application of the Integrated Supercritical Fluid Extraction–Impregnation Process (SFE-SSI) for Development of Materials with Antiviral Properties
(MDPI, 2022)
The integrated supercritical fluid extraction–impregnation process (SFE-SSI) was performed to fabricate material with antiviral properties against the herpes simplex virus (HSV). Cotton gauze and starch/chitosan polymer ...
α-Tricalcium phosphate/fluorapatite-based cement – Promising dental root canal filling material
(University of Novi Sad, Faculty of Technology, 2022)
α-Tricalcium phosphate/fluorapatite (α-TCP/FAp) mixed powders were prepared in order to obtain dental root canal filling cements. Different liquids for cement pastes have been investigated and the most suitable one for ...
Deterioration Characterization during Thermal Shock Testing
(International Institute for the Science of Sintering (IISS), 2023)
Thermal shock stability plays a great role in the selection of optimal refractory material. Different methods of characterization were developed for this purpose, including the implementation of nondestructive testing. ...
