Multivariate Assessment and Risk Ranking of Pesticide Residues in Citrus Fruits
(MDPI, 2023)
Pesticides are extensively used in the cultivation and postharvest protection of citrus fruits, therefore continuous monitoring and health risk assessments of their residues are required. This study aimed to investigate ...
Magneto-Mechanical and Thermal Properties of Nd-Fe-B-Epoxy-Bonded Composite Materials
(MDPI, 2023)
Polymer-bonded magnets are a class of composite material that combines the magnetic properties of metal particles and the molding possibility of a polymeric matrix. This class of materials has shown huge potential for ...
Isotherm, Thermodynamic and Kinetic Studies of Elemental Sulfur Removal from Mineral Insulating Oils Using Highly Selective Adsorbent
(MDPI, 2023)
Elemental sulfur (S8) is a corrosive sulfur compound which was found to be extremely reactive to silver, causing intensive silver sulfide (Ag2S) deposition on on-load tap changer (OLTC) contacts in power transformers. A ...
The study of composition-properties relationships for composite hydrogels based on poly(methacrylic acid) and high concentrations of MFI zeolite
(Elsevier, 2023)
High concentrations of hydrophobic MFI zeolite (26.0–51.3 wt%) were successfully embedded in poly(methacrylic acid) (PMAA) network in simple, one-pot synthesis of PMAA-MFI composite hydrogels. The effects of zeolite ...
Biodegradable Cellulose/Polycaprolactone/Keratin/Calcium Carbonate Mulch Films Prepared in Imidazolium-Based Ionic Liquid
(MDPI, 2023)
Ionic liquid 1-butyl-3-methylimidazolium chloride [BMIM][Cl] was used to prepare cellulose (CELL), cellulose/polycaprolactone (CELL/PCL), cellulose/polycaprolactone/keratin (CELL/PCL/KER), and cellulose/polycaprolactone/ ...
On the Stark broadening of the Re II spectral lines
(Elsevier Ltd., 2023)
Stark broadening parameters - full widths at half maximum (FWHM) and shifts for 11 Re II lines have been calculated. The plasma parameters used were electron density of 1017 cm−3 and temperature from 5 000 K to 80 000 K. ...
Thermodynamic and kinetic analysis of jarosite Pb–Ag sludge thermal decomposition for hydrometallurgical utilization of valuable elements
(Springer Science and Business Media B.V., 2023)
Jarosite is a specific type of hazardous waste determined by the origin of the primary raw materials of the hydrometallurgical process of zinc production. It represents a very demanding raw material for further treatment ...
Recovering the Soybean Hulls after Peroxidase Extraction and Their Application as Adsorbent for Metal Ions and Dyes
(Hindawi Limited, 2023)
This study is aimed at extending the soybean hulls' lifetime by their utilization as an adsorbent for metal ions (Cd2+ and Cu2+) and dyes (Reactive Yellow 39 (RY 39) and Acid Blue 225 (AB 225)). ATR-FTIR spectroscopy, ...
Multicomponent solid solution with pyrochlore structure / Solución sólida multicomponente con estructura de pirocloro
(Sociedad Espanola de Ceramica y Vidrio, 2023)
Multicomponent oxide with pyrochlore structure (A2B2O7), containing 7 different A-site cations and 3 B-site cations in equiatomic amounts, was synthesized. Powders with nominal composition (La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Y ...
A closed cycle of sustainable development: Effective removal and desorption of lead and dyes using an oxidized cellulose membrane
(Elsevier B.V., 2023)
Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linters
cross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystal
violet (CV) ...
