A new insight into the mechanism of lead electrodeposition: Ohmic-diffusion control of the electrodeposition process
(Elsevier, 2013)
A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology ...
Ultraviolet Protection Factor of Gray-state Plain Cotton Knitted Fabrics
(Sage Publications Ltd, London, 2009)
The protection provided by clothing against ultraviolet (UV) radiation has been the subject of considerable recent research. However, a lack of investigations concerned with the influence of yarn properties on UV protection ...
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIO-MOL 490 K. welded by MAC (CO2) welding method. ...
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 ...
Native bovine hemoglobin reduces differentiation capacity of mesenchymal stromal cells in vitro
(Elsevier, Amsterdam, 2020)
We have tested in vitro effects of hemoglobin from bovine slaughterhouse blood (BHb) on stromal cells of mesodermal origin, with an aim to explore its use as a component of cell culture media. Human peripheral blood ...
On the photophysical properties of a liquid crystal dimer based on 4-nitrostilbene: A combined experimental and theoretical study
(Journal of Molecular Liquids, 2021)
A new liquid crystal dimer, 1,12-bis(4-(2-(4-nitrophenyl)ethenyl)phenoxy)dodecane, was synthesized and structurally characterized. The compound exhibited enantiotropic nematic phase. The spectroscopic properties were ...
New Facile One-Pot Synthesis of Isobutyl Thiocarbamate in Recycling Solvent Mixture
(Minerals, 2021)
The specific objectives of the presented study were related to the optimization of the production process of N-alkyl-, N,N-dialkyl-, and N-cycloalkyl-O-isobutyl thiocarbamate; trial industrial production of N-ethyl-O-isobutyl ...
Optimization of forced periodic operations in milli-scale fixed bed reactor for Fischer-Tropsch synthesis
(Elsevier, Amsterdam, 2020)
One-dimensional pseudo-homogenous dynamic reactor model, incorporating detailed Fischer-Tropsch kinetics, was applied in a theoretical analysis of forced periodic operations. A milli-scale fixed-bed reactor was analyzed, ...
Production of activated carbon derived from waste hemp (Cannabis sativa) fibers and its performance in pesticide adsorption
(Elsevier, Amsterdam, 2015)
The main objective of this work was to find optimal production parameters for the preparation of activated hemp fibers (ACh) with good adsorption properties toward pesticides. In order to examine the role of manufacturing ...
