Antifungal activity of Ag:hydroxyapatite thin films synthesized by pulsed laser deposition on Ti and Ti modified by TiO2 nanotubes substrates
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HA) is a widely used biomaterial for implant thin films, largely recognized for its excellent capability to chemically bond to hard tissue inducing the osteogenesis without immune response from human tissues. ...
The forecasting of municipal waste generation using artificial neural networks and sustainability indicators
(Springer Japan Kk, Tokyo, 2013)
The feasibility of modeling municipal waste generation (MWG) for countries at different levels of development using artificial neural networks (ANN) and selected generic indicators of sustainability was investigated. The ...
Increase in bioethanol production yield from triticale by simultaneous saccharification and fermentation with application of ultrasound
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: Bioethanol produced from renewable biomass, such as sugar, starch or lignocellulosic materials, is one of the alternative energy resources that is environmentally friendly. Triticale crops have a high yield as ...
Advances in interactive supported electrocatalysts for hydrogen and oxygen electrode reactions
(Elsevier, 2007)
Magneli phases [A. Magneli, Acta Chem. Scand. 13 (1959) 5] have been introduced as a unique electron conductive and interactive support for electrocatalysis both in hydrogen (HELR) and oxygen (OELR) electrode reactions in ...
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 ...
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 ...
Modelling and optimization of supercritical CO2 extraction of St. John's Wort (Hypericum perforatum L.) using genetic algorithm
(Elsevier Science Bv, Amsterdam, 2012)
Modelling and optimization of the extraction of St. John's Wort using supercritical fluid is the subject of this study. Applying conservation of mass, two partial differential equations were written for solute concentration ...
Investigation of copper-alginate microbeads as antimicrobial materials for potential biomedical applications
(Wiley-Blackwell, Hoboken, 2012)
Properties and drug release profile of poly(N-isopropylacrylamide) microgels functionalized with maleic anhydride and alginate
(Springer, New York, 2013)
This study highlights the advantages of functionalized poly(N-isopropylacrylamide) (PNIPAAm) microgels over pure PNIPAAm microgels in terms of polymer network properties and drug release profiles. PNIPAAm network was ...
Influence of surface modified TiO2 nanoparticles by gallates on the properties of PMMA/TiO2 nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Nanocomposites based on poly(methyl methacrylate) (PMMA) and TiO2 nanoparticles were synthesized by in situ radical polymerization of MMA in solution. The surface of TiO2 nanoparticles was modified with four gallic acid ...
