Ethyl 3-(6-phenyl-44-1,2-dithiolo[1,5-b][1,2,4]dithiazol-2-yl) propanoate
(International Union of Crystallography, 2008)
The title compound, C15H15NO2S3, exists in a bicyclic form, with resonance contributions from two monocyclic forms, each without a second S - S bond. The trithiapentalene heterocyclic ring system is planar, with a mean ...
The structure, growth and reactivity of electrodeposited Ru/Au(111) surfaces
(Elsevier, 2001)
In order to elucidate electronic effects on the oxidation of CO on small Ru clusters, we investigated this reaction on well defined Ru/Au(111) model systems via parallel in-situ STM studies of the structure and electrochemical ...
Co-aluminosilicate based electrodes
(Elsevier, 2010)
The influence of aluminosilicate support on the catalyst efficiency was investigated. Three different aluminosilicate materials containing cobalt (II) ion as active specie for phenol or nitrite oxidation were obtained. The ...
Two-dimensional gradient-index metamaterial with sawtooth profile
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2013)
We investigate theoretically and experimentally a binary metal-dielectric metamaterial with a sawtooth profile. The structure consists of a two-dimensional array of pillars with submicrometer diameters. The pillar diameters ...
Photochemical activation of air pollutants, related to the preservation of cultural heritage / Fotohemijska aktivacija zagađivača vazduha i veza sa očuvanjem kulturnog nasleđa
(Sarajevo : University of East Sarajevo, Faculty of Technology, 2011)
It is well known that the exposition to air and weather markedly enhances derogation of
all artifacts. In this report, the contribution of light (particularly sunlight) to marked speed-up
of the oxidation and other changes ...
Quantification of the lift height for magnetic force microscopy using 3D surface parameters
(Elsevier, 2010)
In this work, the quantitative conditions for the lift height for imaging of the magnetic field using magnetic force microscopy (MFM) were optimized. A thin cobalt film deposited on a monocrystalline silicon (1 0 0) substrate ...
Powdered sample analysis in a double plasma arc source in a graphite tube
(Elsevier, 1977)
A double plasma d.c. arc burning in a horizontal graphite tube in a magnetic field was developed as a light source for spectrochemical purposes. It was demonstrated experimentally that a prolongation of the residence time ...
Antioxidative and immunomodulating activities of polysaccharide extracts of the medicinal mushrooms Agaricus bisporus, Agaricus brasiliensis, Ganoderma lucidum and Phellinus linteus
(Elsevier Sci Ltd, Oxford, 2011)
Partially purified polysaccharides were obtained from four medicinal mushroom species, Agaricus bisporus, Agaricus brasiliensis, Phellinus linteus and Ganoderma lucidum by hot water extraction, followed by ethanol ...
The edible mushroom Laetiporus sulphureus as potential source of natural antioxidants
(Informa Healthcare, London, 2013)
Hot water extract (LN), partially purified polysaccharides (LP) and hot alkali extracted polysaccharides (LNa) obtained from fruiting bodies of the wild basidiomycete Laetiporus sulphureus were examined for their antioxidant ...
Artificial intelligence-based optimization of a bimorph-segmented tapered piezoelectric mems energy harvester for multimode operation
(MDPI, 2021)
This paper presents a study on the design and multiobjective optimization of a bimorph-segmented linearly tapered piezoelectric harvester for low-frequency and multimode vibration energy harvesting. The procedure starts ...
