Poly(ethylene glycol) diacrylate as a novel chaotropic compound for design of aqueous biphasic systems
(Elsevier Science Bv, Amsterdam, 2018)
In this work novel solvent, poly(ethylene glycol) diacrylate (PEGDA) of average number molecular weight 700, is proposed for design of aqueous biphasic systems with salting-out agents: K3PO4/Na3C6H5O7/K2CO3/MnSO4/Li2SO4/ZnSO4. ...
RuOx nanoparticles deposited on TiO2 nanotube arrays by ion-exchange method as electrocatalysts for the hydrogen evolution reaction in acid solution
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Nanocomposite cathodes for the hydrogen evolution reaction (HER) were prepared by deposition of RuOx catalyst particles on self-organized titania nanotube (TiNT) arrays of highly developed surface area, following a procedure ...
Erythrocyte membranes from slaughterhouse blood as potential drug vehicles: Isolation by gradual hypotonic hemolysis and biochemical and morphological characterization
(Elsevier, Amsterdam, 2014)
The present study was aimed at investigating the effect of isolation process-gradual hypotonic hemolysis on chosen parameters of the erythrocyte membranes (ghosts) originating from bovine and porcine slaughterhouse blood. ...
Estimation of residual strength of a crack-containing welded pressure vessel exposed to a subzero operating temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
This paper presents a method for estimating the residual-strength of welded pressure vessel made of HSLA steel which contains a surface axial crack. In order to analyze the behavior of the structure, a set of specimens ...
Prediction of bed expansion of polydisperse quartz sand mixtures fluidized with water
(Elsevier Science Bv, Amsterdam, 2016)
In this paper, the minimum fluidization velocity and bed expansion of polydisperse sand mixtures fluidized with water were investigated. The fluidization experiments were carried out using 19 different fractions of quartz ...
Corrosion of mild steel with composite polyaniline coatings using different formulations
(Elsevier Science Sa, Lausanne, 2015)
The protective abilities of composite coatings based on electrochemically and chemically formed polyaniline powder against the corrosion of mild steel were investigated. A polyaniline powder has been prepared in the form ...
Bifunctional catalytic activity of Zn1-xFexO toward the OER/ORR: seeking an optimal stoichiometry
(Royal Soc Chemistry, Cambridge, 2020)
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1-xFexO,x= 0, 0.05, 0.1, 0.15 and 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen reduction ...
Supercritical and high pressure subcritical fluid extraction from Lemon balm (Melissa officinalis L., Lamiaceae)
(Elsevier, Amsterdam, 2016)
Analysis of yield and composition profile of Melissa officinalis (Lemon balm) extract obtained by two-step CO2 extraction at high pressure was analyzed. The first or essential oil fraction, collected at 10 MPa and 40 degrees ...
The influence of calcium-carbonate and yeast extract addition on lactic acid fermentation of brewer's spent grain hydrolysate
(Elsevier Science Bv, Amsterdam, 2015)
Brewer's spent grain (BSG) is the major by-product of the brewing industry, representing around 85% of the total. by-products generated. In this study BSG hydrolysate was produced using optimal conditions. Hydrolysates ...
Influence of sintering temperature on low level laser (LLL) destruction of low cement high alumina refractory concrete
(Elsevier Sci Ltd, Oxford, 2015)
Low level laser (LLL) was applied to induct destruction of the low cement high alumina refractory concrete (LCC) samples. Three different series of samples were used in the experiment: a reference one dried at 105 degrees ...
