Production of bioethanol from corn meal hydrolyzates by free and immobilized cells of Saccharomyces cerevisiae var. ellipsoideus
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The ethanol fermentation of enzymatically obtained corn meal hydrolyzates by free and immobilized Saccharomyces cerevisiae var. ellipsoideus yeast in a batch system was studied. The initial glucose and inoculum concentration ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt")/Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
The validity of the general similarity law for electrical breakdown of gases
(IOP Publishing Ltd, Bristol, 2006)
This paper investigates the validity of the similarity law in cases of dc and pulse breakdown of gases. Geometrically similar systems insulated with SF6 gas were used during experiments. It is shown that the similarity law ...
Quantifying shapes of nanoparticles using modified circularity and ellipticity measures
(Measurement, 2016)
We propose using a new circularity measure, and an ellipticity measure. Observing an example of hematite (alpha-Fe2O3) nanoparticles, we compared and discussed a new circularity measure, with a standard measure. It has ...
Ru layers electrodeposited onto highly stable Ti2AlC substrates as cathodes for hydrogen evolution in sulfuric acid solutions
(Elsevier, 2016)
In this work, the hydrogen evolution reaction (HER) was studied on Ru coated Ti2AlC electrodes in 1.0 mol dm(-3) H2SO4 at 25 degrees C. Ti2AlC was found to be a highly stable substrate in sulfuric acid solutions due to the ...
Poly(urethane-dimethylsiloxane) copolymers displaying a range of soft segment contents, noncytotoxic chemistry, and nonadherent properties toward endothelial cells
(Wiley-Blackwell, Hoboken, 2015)
Polyurethane copolymers based on ,-dihydroxypropyl poly(dimethylsiloxane) (PDMS) with a range of soft segment contents were prepared by two-stage polymerization, and their microstructures, thermal, thermomechanical, and ...
Novel Hybrid Nanostructures of Carbon Nanotube/Fullerene-like Tungsten Disulfide as Reinforcement for Aramid Fabric Composites
(Fibers and Polymers, 2021)
Multilayered composites based on aramid fabrics are widely used in impact protection. The objective of this study is creating a new kind of multiaxial aramid fabric composites with inorganic fullerene-like tungsten disulfide ...
Cleaner production aspects of tablet coating process in pharmaceutical industry: problem of VOCs emission
(Elsevier Sci Ltd, Oxford, 2013)
The aim of the article is to present a case study related to implementation of cleaner production (CP) process with the concept of minimizing emissions versus the end of pipe (EOP) approach within pharmaceutical industry. ...
Pb(II) removal from aqueous solution by Myriophyllum spicatum and its compost: equilibrium, kinetic and thermodynamic study
(Wiley, Hoboken, 2014)
BACKGROUND Lead is one of the frequent contaminants of industrial wastewater. Since it has been shown that aquatic plants can be used for the removal of heavy metals, herein Pb(II) biosorption by Myriophyllum spicatum and ...
Silver/Poly(N-vinyl-2-pyrrolidone) Hydrogel Nanocomposites Obtained by Electrochemical Synthesis of Silver Nanoparticles Inside the Polymer Hydrogel Aimed for Biomedical Applications
(Wiley, Hoboken, 2014)
Silver nanoparticles were produced inside a poly(N-vinyl-2-pyrrolidone) hydrogel (PVP) by an innovative method based on the electrochemical reduction of Ag+ ions within the swollen PVP hydrogel. UV-visible spectroscopy ...
