Nanocomposite microfibers based on alginate and PVA hydrogels with incorporated silver nanoparticles
(Wiley-Blackwell, Hoboken, 2012)
Microstructure of new composite electrocatalyst and its anodic behavior for chlorine and oxygen evolution
(Elsevier Sci Ltd, Oxford, 2012)
The first layer of active coating made from a rutile-structured solid solution of ruthenium and titanium dioxides having an average crystal grain size of 30 nm was thermally deposited on an adequately prepared titanium ...
In vitro investigation of cytotoxicity and antimicrobial activity of silver/alginate nanocomposite microbeads
(Wiley-Blackwell, Hoboken, 2012)
Alginate hydrogel microbeads incorporated with Ag nanoparticles obtained by electrochemical method
(Elsevier Science Sa, Lausanne, 2012)
An innovative method was developed for production of alginate hydrogel microbeads incorporated with silver nanoparticles (AgNPs) based on electrochemical synthesis followed by electrostatic extrusion. AgNPs were synthesized ...
Investigation of silver impact on hydroxyapatite/lignin coatings electrodeposited on titanium
(Elsevier Science Sa, Lausanne, 2013)
Silver doped hydroxyapatite (HAP) [Ca9.95Ag0.05(PO4)(6)(OH)(2)] composite coatings with natural polymer organosolv lignin (Lig) were produced by electrophoretic deposition (EPD) on titanium. Coatings were characterized by ...
Conventional and spark-plasma sintering of cordierite powders synthesized by sol-gel methods
(Elsevier Sci Ltd, Oxford, 2013)
Cordierite powders synthesized by colloidal and alkoxide sol-gel methods were conventionally and spark-plasma sintered. The powders for the sintering investigations were obtained by calcination of the gels at a temperature ...
Isopiestic determination of the osmotic and activity coefficients of the {yKBr + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, ...
Catalytic activity of SnO2- and SO4/SnO2-containing clinoptilolite in the esterification of levulinic acid
(Elsevier B.V., 2019)
Catalysts based on natural zeolite – clinoptilolite loaded with either SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) were prepared and tested in the esterification of levulinic acid (LA) with octanol or ethanol. The Sn content ...
Solubility of thymol in supercritical carbon dioxide and its impregnation on cotton gauze
(Elsevier Science Bv, Amsterdam, 2013)
Through this study, an attempt has been made to evaluate the solubility of thymol in supercritical carbon dioxide as well to investigate a prospect of its impregnation on cotton gauze on laboratory scale. Solubility of ...
Microwave-assisted extraction for the recovery of antioxidants from waste Equisetum arvense
(Elsevier, Amsterdam, 2014)
Microwave-assisted extraction was optimised by the response surface methodology in order to enhance the extraction of polyphenols from Equisetum arvense (horsetail). Under the optimal conditions the total polyphenol content ...
