Comparison of properties of silver-metal oxide electrical contact materials
(Technical Faculty, Bor, 2012)
Changes in physical properties such as density, porosity, hardness and electrical conductivity of the Ag-SnO2 and Ag-SnO2In2O3 electrical contact materials induced by introduction of metal oxide nanoparticles were investigated. ...
Morphological and crystallographic characteristics of electrodeposited lead from a concentrated electrolyte
(The Royal Society of Chemistry, 2013)
Electrodeposition of lead from a concentrated nitrate solution was examined by scanning electron microscopy (SEM) and by X-ray diffraction (XRD) analysis of the obtained powder particles. Single crystals of the (111) ...
Tamm plasmon modes on semi-infinite metallodielectric superlattices
(Springer Science and Business Media LLC, 2017)
We analyze the fundamental properties of optical waves referred to as Tamm plasmon modes (TPMs) which are tied to the interface of a semi-infinite two-phase metallodielectric superlattice with an arbitrary homogeneous ...
Evaluation of Genotoxic Pressure along the Sava River
(Public Library of Science (PLoS), 2016)
In this study we have performed a comprehensive genotoxicological survey along the 900 rkm of the Sava River. In total, 12 sites were chosen in compliance with the goals of GLOBAQUA project dealing with the effects of ...
Gyroid Nickel Nanostructures from Diblock Copolymer Supramolecules
(Journal Of Visualized Experiments, Cambridge, 2014)
Nanoporous metal foams possess a unique combination of properties - they are catalytically active, thermally and electrically conductive, and furthermore, have high porosity, high surface-to-volume and strength-to-weight ...
Curcumin loaded pegylated nanoemulsions designed for maintained antioxidant effects and improved bioavailability: A pilot study on rats
(MDPI, 2021)
The current study describes the experimental design guided development of PEGylated nanoemulsions as parenteral delivery systems for curcumin, a powerful antioxidant, as well as the evaluation of their physicochemical ...
Surface and thermomechanical characterization of polyurethane networks based on poly(dimethylsiloxane) and hyperbranched polyester
(Budapest University of Technology, 2013)
Two series of polyurethane (PU) networks based on Boltorn (R) hyperbranched polyester (HBP) and hydroxyethoxy propyl terminated poly(dimethylsiloxane) (EO-PDMS) or hydroxy propyl terminated poly(dimethylsiloxane) (HP-PDMS), ...
Electrodeposition of Co-Ni-MoxOy Powders: Part I. The Influence of Deposition Conditions on Powder Composition and Morphology
(Springer, New York, 2010)
The Co-Ni-MoxOy powders were obtained electrochemically at a constant current density from ammonia electrolyte. Ni and Co were anomalously deposited, inducing Mo deposition, which cannot be deposited separately from aqueous ...
STRUCTURE AND PROPERTIES OF NANOSIZE NiFe2O4 PREPARED BY TEMPLATE AND PRECIPITATION METHODS
(Technical Faculty, Bor, 2013)
Nanosize NiFe2O4 was prepared by template method and precipitation process using same starting materials. The use of soluble starch in both synthesis routes was investigated. The amount of the used precipitating agent ...
Synthesis of endoperoxides by domino reactions of ketones and molecular oxygen
(Royal Soc Chemistry, Cambridge, 2015)
Domino reactions of ketones with molecular oxygen in the presence of potassium hydroxide and potassium t-butoxide afford cyclic hydroperoxy acetals (3,5-dihydroxy-1,2-dioxanes). Mixed endoperoxides can also be obtained in ...
