Sustained release of alpha-lipoic acid from chitosan microbeads synthetized by inverse emulsion method
(Elsevier Science Bv, Amsterdam, 2016)
The aim of this study was to investigate the encapsulation of a-lipoic acid (LA) onto chitosan microbeads in order to achieve a sustained release. Microbeads of different compositions were synthetized by inverse emulsion ...
Thermal properties and thermal stability of PP/MWCNT composites
(Elsevier Sci Ltd, Oxford, 2016)
The effects of the filler size and content on thermal properties and thermal stability of polypropylene (PP) composites filled with four different sizes of multi-walled carbon nanotubes (MWCNTs) were investigated through ...
Calcium-Alginate-Inulin Microbeads as Carriers for Aqueous Carqueja Extract
(Wiley, Hoboken, 2016)
Carqueja (Pterospartum tridentatum) is an endemic species and various bioactive compounds have been identified in its aqueous extract. The aim of this study was to protect the natural antioxidants from the aqueous extract ...
Single step recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction
(Taylor & Francis Inc, Philadelphia, 2016)
Recovery of lipase from Penicillium cyclopium by aqueous two-phase extraction was studied with maximal possible crude enzyme loads. In polyethylene glycol/dextran and polyethylene glycol/salt systems the influences of ...
Thermal stability and degradation of binuclear hexaaqua-bis(ethylenediamine)-(mu (2)-pyromellitato)dinickel(II) tetrahydrate
(Springer, Dordrecht, 2016)
Thermal degradation of ternary transition metal complex containing tetraanion of pyromellitic acid, pyr, and ethylenediamine, en, [Ni-2(en)(2)(H2O)(6)(pyr)]center dot 4H(2)O, 1, was investigated under non-isothermal ...
Electrochemical oxidation of ethanol on palladium-nickel nanocatalyst in alkaline media
(Elsevier, Amsterdam, 2016)
Pd-Ni/C catalyst was synthesized employing a borohydride reduction method. The high area Ni was first dispersed on the carbon support and then modified by Pd nanoparticles. Transmission electron microscopy confirmed ...
Antimicrobial Activity of Lactic Acid Against Pathogen and Spoilage Microorganisms
(Wiley, Hoboken, 2016)
Preliminary examination of the antimicrobial activity of lactic acid against nine bacteria (Escherichia coli, Proteus mirabilis, Salmonella enteritidis, Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, ...
Shear bond strength to dentine of dental adhesives containing hydroxyapatite nano-fillers
(Taylor & Francis Ltd, Abingdon, 2016)
The aim of this study was to compare the effect of hydroxyapatite (HAP) nano-rods (HAP rods) and HAP nano-sticks (HAP sticks) added to commercial adhesives on the macro-shear bond strength (SBS) to dentine and morphology ...
Ultra-high pressure densification and properties of nanostructured SiC
(Elsevier Science Bv, Amsterdam, 2016)
Cubic SiC nano-powder particles were synthesized by a sal-gel process with an average grains size of 9.5 nm which were subsequently densified by using a high-pressure "anvil-type with hollows" apparatus at a pressure of 4 ...
Monolithic nanocrystalline SiC ceramics
(Elsevier Sci Ltd, Oxford, 2016)
Additive-free beta-SiC nanopowders were densified by using high-pressure "anvil-type with hollows" apparatus at the pressure of 4 GPa in the range of 1500-1900 degrees C. The starting powder with average particle size of ...
