Polymer-Lipid Matrices based on Carboxymethyl Cellulose/Solagum and Liposomes for Controlled Release of Folic Acid
(John Wiley and Sons Inc., 2023)
Liposome-encapsulated folic acid is incorporated into the films made from sodium carboxymethyl cellulose (CMC) (2 mas%) and a mixture of CMC and solagum (9:1 w/w) using the film-forming cast solution method. Histidine is ...
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 ...
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 ...
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, ...
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 ...
Multiblock copolymers containing poly(butylene succinate) and poly(ε-caprolactone) blocks: Effect of block ratio and length on physical properties and biodegradability
(Springer Science and Business Media B.V., 2022)
In order to obtain polymers with preserved thermal properties and tunable biodegradability multiblock copolymers comprising blocks of biodegradable polyesters poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) ...
Multispectral electromagnetic shielding and mechanical properties of carbon fabrics reinforced by silver deposition
(Materials Chemistry and Physics, 2022)
Electromagnetic interference (EMI) has become a widespread modern environmental pollutant. There is an essential need for practical and applicable materials for its attenuation. Therefore, the presented research has focused ...
Statistical methods for designing a Geiger–Muller counter suitable for an early warning system
(Elsevier B.V., 2022)
The paper discusses statistical methods that can be applied when constructing the Geiger–Muller counters to obtain the same response to radiation, regardless of their dimensions. This issue is relevant for the improvement ...
Volumetric and Transport Properties of Isoamyl Acetate Based Binary Systems-Experimental Determination and Modeling
(American Chemical Society, 2022)
Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the ...
Deep Eutectic Solvent Based Reversed-Phase Dispersive Liquid–Liquid Microextraction and High-Performance Liquid Chromatography for the Determination of Free Tryptophan in Cold-Pressed Oils
(MDPI, 2023)
A fast and straightforward reversed-phase dispersive liquid–liquid microextraction (RP-DLLME) using a deep eutectic solvent (DES) procedure to determine free tryptophan in vegetable oils was developed. The influence of ...
