Hybrid amino-terminated lignin microspheres loaded with magnetite and manganese oxide nanoparticles: An effective hazardous oxyanions adsorbent
(Elsevier Ltd., 2022)
Highly effective lignin-based microspheres were prepared by inverse copolymerization of lignin (kraft) from suspension, with poly(ethylene imine) and amino-functionalized magnetite nanoparticles (A-LMS_Fe3O4) or ...
Polyphenol extraction in microwave reactor using by-product of Thymus serpyllum L. and biological potential of the extract
(Elsevier GmbH, 2022)
In the present study, polyphenol extraction from Thymus serpyllum by-product (herbal dust) in microwave reactor was optimized through varying extraction time, ethanol concentration and solid-to-solvent ratiovia determination ...
Alkali Treated Jute Fabrics Suitable for the Production of Inexpensive Technical Textiles
(Korean Fiber Society, 2022)
This work aimed to obtain jute fabrics suitable for the production of inexpensive technical textiles by using simple alkali treatments. The influences of alkali concentration (1–17.5 % NaOH) and treatment duration (5–30 ...
The effect of equipment design and process scale-up on supercritical CO2 extraction: Case study for Silybum marianum seeds
(Elsevier B.V., 2022)
The present study was focused on improving the supercritical fluid extraction process dedicated to the recovery of highly valuable extract from Silybum marianum seeds. At first, the process was tested using supercritical ...
Electrochemical Behavior of Duloxetine Hydrochloride at Au and GC Solid Electrodes: Its Quantitative Determination and Degradation
(The Electrochemical Society, 2022)
Duloxetine hydrochloride (DUL) is effective in treating depression, and was examined for electroanalytical purposes. The DULstandard was investigated by cyclic voltammetry (CV) and determined using differential pulse ...
Green manufacturing of high-value extracts from milk thistle seeds: Parameters that affect the supercritical CO2extraction process
(Elsevier Ltd, 2022)
The aim of this study was to provide insights into parameters that affect the oil extraction from an industrially valuable raw material (milk thistle) using green solvent supercritical CO2. The effect of plant origin, ...
Unravelling conformational and crystal packing preferences of cyclohexane-5-spirohydantoin derivatives incorporating a halogenated benzoyl group
(Royal Society of Chemistry, 2022)
Two spirohydantoin derivatives, 3-(4-chlorobenzoyl)-1,3-diazaspiro[4.5]decane-2,4-dione (1) and 3-(4-bromobenzoyl)-1,3-diazaspiro[4.5]decane-2,4-dione (2), were synthesized and analyzed by single crystal X-ray diffraction, ...

(Elsevier B.V., 2022)
In order to improve the performance of theoretical UV–Vis spectra predictions, a theoretical and experimental study of solvatochromic properties of ten azo pyridone dyes has been performed. For quantitative estimation of ...
Titanium doped yttrium manganite: improvement of microstructural properties and peculiarities of multiferroic properties
(Springer, 2022)
Yttrium manganite, YMnO3, was doped with different concentrations of titanium (x = 0, 0.04, 0.08, 0.10, 0.15, 0.20) in order to improve the microstructural and multiferroic properties. The powders were prepared using sol-gel ...
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 ...
