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 ...
Kinetic Model for Galacto-Oligosaccharide Synthesis
(American Chemical Society, 2022)
A new micro-kinetic model is proposed for galacto-oligosaccharide (GOS) synthesis with β-galactosidase from Aspergillus oryzae. Several kinetic models with similar reaction mechanisms, i.e., steps and kinetic constants, ...
One-Pot Syntheses of PET-Based Plasticizer and Tetramethyl Thiuram Monosulfide (TMTS) as Vulcanization Accelerator for Rubber Production
(MDPI, 2023)
Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained ...
Potential of organic carbonates production for efficient carbon dioxide capture, transport and storage: Reaction performance with sodium hydroxide–ethanol mixtures
(Elsevier Ltd, 2023)
Carbon dioxide storage is one of the main long-term strategies for reducing carbon dioxide emissions in the atmosphere. A clear example is Norway's Longship project. If these projects should succeed, the transport of huge ...
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 ...
Morphological and Structural Characterization of MgAl2O4 Spinel
(International Institute for the Science of Sintering (IISS), 2023)
Magnesium aluminate has the spinel structure along with good mechanical, chemical, and thermal properties. Magnesium aluminate has a wide range of applications including refractory ceramics, optically transparent ceramic ...
Cerium citrate as ecologically friendly corrosion inhibitor for AA7075 alloy
(Materials and Corrosion-Werkstoffe Und Korrosion, 2022)
The corrosion behaviour of high-strength AA7075 aluminium alloy in NaCl solution, without and in the presence of environmentally friendly corrosion inhibitors (Ce-chloride and Ce-citrate) in low concentrations ( lt 0.5 ...
Electrochemical formation and behavior of silver and lead chlorides as potential cathodes for quasi-rechargeable magnesium seawater cell
(Springer, 2023)
Primary seawater magnesium-based cell with AgCl or PbCl2 cathodes is widely used as power sources. In this paper, we consider the cyclic galvanostatic formation of silver and lead chlorides and their electrochemical behavior ...
The Effect of Acrylate on the Properties and Machinability of Alumina Ceramics
(International Institute for the Science of Sintering (IISS), 2023)
Effect of methyl methacrylate (MMA) as a binder and heating treatment were investigated to improve green alumina compacts machinability. Properties of green compacts and their corresponding sintered samples prepared with ...
Influence of added whey proteins and hydrolysates on rheological and textural characteristics of milk chocolate
(SAGE Publications Inc., 2022)
In order to improve functional characteristics of standard milk chocolate (C) was enriched by the addition of whey protein concentrate (WPC) and whey proteins hydrolyzed by trypsin (H-WPC) in the amount of 6%. The chocolate ...
