Resveratrol loaded liposomes produced by different techniques
(Elsevier Sci Ltd, Oxford, 2013)
Several different methods for production of liposomes incorporating resveratrol were investigated and compared from the aspect of size distribution, surface charge, entrapment efficiency, phase behavior and stability. Thin ...
Extending waste paper, cellulose and filler use beyond recycling by entering the circular economy creating cellulose-CaCO3 composites reconstituted from ionic liquid
(Springer Science and Business Media B.V., 2022)
Cellulose-fibre lifecycle is severely limited within today’s recycling methodology. Feedstock cellulose and filler abound in products considered uneconomic, unsuitable for standard deinking or too weak for original product ...
Effect of YAG content on creep resistance and mechanical properties of Al2O3-YAG composite
(Elsevier Sci Ltd, Oxford, 2020)
Comprehensive study on effect of YAG amount on densification, creep resistance and room-temperature mechanical properties of Al2O3-YAG composite pressureless sintered at 1600 degrees C was conducted. The main goal was to ...
Effect of plasma treatment on chemical composition, structure and sorption properties of lignocellulosic hemp fibers (Cannabis sativa L.)
(Elsevier Sci Ltd, Oxford, 2020)
Hemp fibers with different amount of hemicelluloses and lignin were subjected to atmospheric pressure dielectric barrier discharge under different conditions (40 W and 80 W power of discharge, const. time 120 s) in order ...
Polymer composite films and nanofibers doped with core-shell quantum dots
(Natl Inst Optoelectronics, Bucharest-Magurele, 2020)
Processing and characterization of polymer nanocomposites based on poly(methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots were investigated. Nanocomposites were obtained via solution casting ...
Structural, microstructural and mechanical properties of sintered iron-doped mullite
(Elsevier, Amsterdam, 2020)
The study of an effect of iron doping on the structural, microstructural and mechanical properties of sintered iron-doped mullite is presented. The results of phase composition, performed in detail by Mossbauer spectroscopy ...
The effect of incompletely condensed polyhedral oligomeric silsesquioxanes (POSS) on hybrid film adhesion
(Elsevier Sci Ltd, Oxford, 2020)
The objective of this study was to investigate the influence of polyhedral oligomeric silsesquioxane (POSS) structure on the adhesion behaviour of composite films onto a metallic surface. The composite films consisted of ...
Surface optical phonon (SOP) mode in ZnS/Poly (methylmethacrylate) nanocomposites
(Elsevier, Amsterdam, 2020)
The polymer nanocomposite ZnS/Poly (methylmethacrylate) was prepared by the solution casting method and its structural and optical properties were investigated using XRD, SEM, TEM, HRTEM, and Raman spectroscopy. The basic ...
Recovery of tungsten trioxide from waste diamond core drilling crowns by nitric acid leaching
(International Journal of Refractory Metals & Hard Materials, 2021)
A cost-effective and simple hydrometallurgy procedure for recycling the diamond core drilling crowns by nitric acid leaching, followed by the sodium hydroxide leaching, has been developed. The effect of temperature, nitric ...
Cytotoxicity of the gold complex based on mercaptotriazole - A comparison with the conventional cyanide electrolyte
(Journal of the Indian Chemical Society, 2021)
The study presents the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay results on human erythroleukemia K562 cell line to compare the toxicity of electrolytes based on the mercaptotriazole gold ...
