Microstructural and compositional aspects of ZnO-based varistor ceramics prepared by direct mixing of the constituent phases and high-energy milling
(Elsevier Sci Ltd, Oxford, 2008)
ZnO-based varistor samples were prepared by the direct mixing of the constituent phases (DMCP) and sintering at 1100 degrees C for 2 h. The influence of the starting powder mixture's composition - the amounts of the ...
The effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
Deconvolution of lignin fluorescence spectra: A contribution to the comparative structural studies of lignins
(Maik Nauka/Interperiodica/Springer, New York, 2007)
In this work, we deconvoluted the fluorescence spectra of lignin and a lignin model compound using a combination of one symmetric ( Gaussian) and the most appropriate number of asymmetric (Log-normal) models. We aimed to ...
Ectomycorrhiza and water transport
(Springer-Verlag Berlin Heidelberg, 2008)
In temperate and boreal regions, seasons are characterized by two major factors - temperature and water availability. As water availability is affecting essential processes like nutrition and photosynthesis, it is of central ...
New Antitumour Natural Products from Marine Red Algae: Covering the Period from 2003 to 2012
(Bentham Science Publ Ltd, Sharjah, 2015)
This review covers the 2003-2012 literature data published for natural products originating from marine red algae. The focus is on new antitumour substances, together with details related to the organism sourced. It ...
Morphology and composition of the Fe-Ni powders electrodeposited from citrate containing electrolytes
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposition of the Fe-Ni powders from citrate containing electrolytes for different Ni/Fe ions concentration ratios, using Fe(Ill) and Fe(II) salts at pH 4.5 and pH 4.0 respectively was investigated by the ...
New Route for Stabilization of 1T-WS2 and MoS2 Phases
(Amer Chemical Soc, Washington, 2011)
The phenomenon of a partial 2H -> 1T phase transition within multiwalled WS2 nanotubes under substitutional rhenium doping is discovered by means of high-resolution transmission electron microscopy. Using density-functional ...
Engineering carbon chains from mechanically stretched graphene-based materials
(Amer Physical Soc, College Pk, 2011)
The electrical response of graphene-based materials can be tailored under mechanical stress. We report different switching behaviors that take place in mechanically deformed graphene nanoribbons prior to the breakage of ...
Optical properties of PbTe doped with Nd
(Springer, New York, 2010)
Single crystals of lead telluride doped with Nd were synthesized using the Bridgeman method. Room temperature far infrared reflectivity spectra were measured for PbTe samples with Nd content in the range 0.2-0.9 at.%. ...
Robust electronic and transport properties of graphene break nanojunctions
(Amer Physical Soc, College Pk, 2011)
We report a systematic research on structural, electronic, and transport properties of a variety of graphene nanoribbon (GNR) break junctions, with different widths and edge chiralities. Our extensive molecular dynamics ...
