In vitro evaluation of enzymatically derived blackcurrant extract as prebiotic cosmetic ingredient: extraction conditions optimization and effect on cutaneous microbiota representatives
(Springer Science and Business Media Deutschland GmbH, 2023)
Background Blackcurrant is a rich source of polyphenols with proven physiological activity, that have lately been classified as emerging prebiotics, making its extracts suitable for application in functional food and ...
Textural and fractal properties of CuO/Al 2 O 3 catalyst supports
(Elsevier, 2006)
Reactive amorphous aluminas with a high surface area, suitable as a precursor for catalyst supports, are obtained by flash calcination of gibbsite in a reactor for pneumatic transport in the dilute two phase flow regime. ...
Initial microstructure effect on the mechanical properties of Ti-6Al-4V ELI alloy processed by high-pressure torsion
(Elsevier Science Sa, Lausanne, 2018)
effect of initial microstructure on the mechanical properties and fracture mode of the Ti-6Al-4V ELI alloy subjected to the high-pressure torsion (HPT) processing at room temperature and 500 degrees C was investigated. In ...
Contribution of lactic acid fermentation to improved nutritive quality vegetable juices enriched with brewer's yeast autolysate
(Elsevier Sci Ltd, Oxford, 2007)
Vegetables are rich sources of the biologically active compounds which have beneficial effects in prevention of some diseases and certain types of cancer. From the point of view of protection and health, the objective of ...
Structure sensitivity of dimethylamine deep oxidation over Pt/Al2O3 catalysts
(Elsevier, 2009)
The deep oxidation of dimethylamine (DMA) was studied over Pt/Al2O3 catalysts with small (1 nm) and large (7.8-15.5 nm) Pt crystallite sizes. The turnover frequency (TOF) was higher for the large than for the small Pt ...
Characterization of sodium alginate/D-limonene emulsions and respective calcium alginate/D-limonene beads produced by electrostatic extrusion
(Elsevier Sci Ltd, Oxford, 2015)
In this study, calcium alginate beads immobilizing D-limonene (solid systems) have been manufactured starting from emulsions of this flavor in sodium alginate (liquid systems). The effects of alginate concentration (0.02 ...
Dislocation glide-controlled room-temperature plasticity in 6H-SiC single crystals
(Elsevier Ltd, 2014)
In situ transmission electron microscopy observations of uniaxial compression of sub-300 nm diameter, cylindrical, single-crystalline 6H-SiC pillars oriented along 〈0001〉 and at 45° with respect to 〈0001〉 reveal that plastic ...
Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier Sci Ltd, Oxford, 2004)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
Synthesis, particle shape characterization, magnetic properties and surface modification of superparamagnetic iron oxide nanochains
(Materials Characterization, 2019)
We report monodisperse, chain-like particles (nanochains) consisted of silica-coated maghemite (γ-Fe2O3) nanoparticle clusters prepared by colloidal chemistry and magnetic field-induced self-assembly of nanoparticle clusters. ...
Physico-chemical, structural, and adsorption properties of amino-modified starch derivatives for the removal of (in)organic pollutants from aqueous solutions
(Elsevier B.V., 2023)
In this study, an environmentally sustainable process of crystal violet, congo red, methylene blue, brilliant green, Pb2+, Cd2+, and Zn2+ ions adsorption from aqueous solutions onto amino-modified starch derivatives was ...
