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, ...
Morphological assessment of cavitation caused damage of cordierite and zircon based materials using principal component analysis
(Elsevier Ltd, 2023)
The pattern recognition approach, explored by this study, applies the principal component analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation and propagation of the cracks and ...
The Rydberg atom-atom collisions: Chemi-ionization cross-sections and rate coefficients in alkali-metal astrophysical and low-temperature laboratory plasmas
(Elsevier Ltd, 2022)
In this manuscript, the chemi-ionization (CI) processes in atom - Rydberg atom collisions are examined. We obtained the cross-sections, as well as rate coefficients for CI processes in potassium and sodium collisions for ...
The overlooked potential of raspberry canes: from waste to an efficient low-cost biosorbent for Cr(VI) ions
(Springer Science and Business Media Deutschland GmbH, 2024)
Screening of various potential biosorbents originated from locally available lignocellulosic biomass has led to the investigation of so far uninvestigated raspberry cane for removal of Cr(VI) ions from aqueous solutions. ...
Supercritical CO2-assisted processes for development of added-value materials: Optimization of starch aerogels preparation and hemp seed extracts impregnation
(Elsevier Ltd, 2022)
The aim of the present study was the utilization of supercritical CO2 as a green medium in various processes: starch gel drying, supercritical extraction from hemp seed flour (SCE process), hemp seed oil (HSO) impregnation ...
Continuous production of fructo-oligosaccharides using selectively immobilized fructosyltransferase from Aspergillus aculeatus onto Purolite® A109
(Korean Society of Industrial Engineering Chemistry, 2023)
Within this study, the investigation of potential selective immobilization of fructosyltransferase (FTase) derived from Aspergillus aculeatus (from commercial enzyme preparation Pectinex® Ultra SP-L) onto the polystyrenic ...
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 ...
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 ...
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 ...
Structure–property correlations for composite hydrogels based on poly(methacrylic acid) and high concentrations of LTA zeolite
(Elsevier, 2024)
High concentrations of LTA zeolite (27-52mass%) were embedded in poly(methacrylic acid) (PMAA) matrix to obtain composite hydrogels with porosity and active sites originating from both components. Substandard mechanics of ...
