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 ...
Unique effects of microwave heating on polymerization kinetics of poly(methyl methacrylate) composites
(Elsevier Science Sa, Lausanne, 2013)
The effects of heating mode (conventional and microwave) on the kinetics of isothermal polymerization of MMA composite materials were investigated. Isothermal kinetics curves at temperature range from 343 K to 363 K for ...
Antimicrobial activity and biocompatibility of Ag--(+) and Cu2+ -doped biphasic hydroxyapatite/alpha-tricalcium phosphate obtained from hydrothermally synthesized Ag+- and Cu2+ -doped hydroxyapatite
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HAp) powders doped with Ag+ or Cu2+ were synthesized by a hydrothermal method in order to obtain biomaterial with an antimicrobial effect. The synthesis was performed with two contents of dopant (Ag+ or ...
Visible light-harvesting of TiO2 nanotubes array by pulsed laser deposited CdS
(Elsevier Science Bv, Amsterdam, 2014)
Titanium dioxide (TiO2) nanotubes arrays, obtained by anodization technique and annealing, were decorated with CdS using pulsed laser deposition method. Their structural, morphological and chemical characterization was ...
Immobilization of lipase on epoxy-activated Purolite((R)) A109 and its post-immobilization stabilization
(Elsevier Sci Ltd, Oxford, 2014)
In this study, Purolite (R) A109, polystyrenic macroporous resin, was used as immobilization support due to its good mechanical properties and high particle diameter (400 mu m), which enables efficient application in enzyme ...
The dependence of the photocatalytic activity of TiO2/carbon nanotubes nanocomposites on the modification of the carbon nanotubes
(Elsevier Sci Ltd, Oxford, 2014)
Nanostructural TiO2/modified multi-wall carbon nanotubes photocatalysts were prepared by hydrolysis of Ti(iso-OC3H7)(4) providing chemical bonding of anatase TiO2 nanoparticles onto oxidized- or amino-functionalized ...
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 impact of sunflower and rapeseed lecithin on the rheological properties of spreadable cocoa cream
(Elsevier Sci Ltd, Oxford, 2016)
The rheological properties of spreadable cocoa cream containing lecithin of different origins (sunflower, rapeseed and soy lecithin) were investigated within this research. A laboratory ball mill was used to produce creams ...
High Energy/Power Supercapacitor Performances of Intrinsically Ordered Ruthenium Oxide Prepared through Fast Hydrothermal Synthesis
(Wiley-VCH Verlag Gmbh, Weinheim, 2017)
A simple one-step microwave-assisted and temperature-controlled hydrothermal synthesis was applied to prepare a nanocrystalline RuO2 dispersion from an aqueous solution of RuCl3 for supercapacitive applications. The obtained ...
Preparation of beechwood/polymer composites using the method of lyophilization and gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Wooden cultural heritage serves as a very important source of information for historians and researchers. Also, it imposes an obligation on the science to keep this legacy for future generations in a proper condition. Among ...
