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 ...
Raw kaolinitic–illitic clays as high-mechanical-performance hydraulically pressed refractories
(Springer Science and Business Media B.V., 2022)
The usage possibility of 19 composites of raw refractory clays from Serbia containing approximately 53.29% of SiO2 and 26.73% of Al2O3 is presented. The sum of fluxing oxides was 57.74%, while these materials contained 32% ...
Soft 3D hybrid network for delivery and controlled release of poorly soluble dihydropyrimidinone compound: An insight into the novel system for potential application in leukemia treatment
(John Wiley and Sons Inc., 2022)
Researchers are faced with everyday demands for safer and more efficient therapy for many diseases, especially serious one such as various types of cancer. Numerous anticancer drugs are poorly-water soluble and therefore ...
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 ...
Introducing the azocinnamic acid scaffold into bent-core liquid crystal design: A structure–property relationship study
(Elsevier B.V., 2022)
A series of bent-core liquid crystals possessing the azocinnamoyl unit in both elongating side arms was synthesized. The chain length was kept fixed for each molecule (C12H25), whereas the substituents at the central and ...
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 ...
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, ...
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 ...
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. ...
