Evaluation of the composition and morphology of a WTi/Si system processed by a picosecond laser
(Korean Inst Metals Materials, Seoul, 2012)
In this work we studied the influence of laser radiation on the composition, structure and morphology of WTi thin films deposited on n-type (100) silicon wafers. The films were deposited by d.c. sputtering from a 70:30 at% ...
Solid State Synthesis of Extra Phase-Pure Li4Ti5O12 Spinel
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800 ...
Fatty Acids of Some Moss Species from Germany
(Asian Journal Of Chemistry, Sahibabad, 2011)
The fatty acid composition of three mosses collected in Germany was preliminary analyzed by gas chromatography (GC-FID) and gas I chromatography-mass spectrometry (GC-MS) for the first time. It was found that Hypnum ...
Inappropriately chelated iron in the cerebrospinal fluid of amyotrophic lateral sclerosis patients
(Informa Healthcare, London, 2012)
ALS is characterized by oxidative damage in the brain and cerebrospinal fluid, which is exerted by pro-oxidative activity of iron. Such activity of iron can be drastically increased in the presence of inappropriate iron ...
Comparative research of accumulation of heavy metals in woody plants and herbs
(Parlar Scientific Publications (P S P), Freising, 2011)
Vascular plants can precisely indicate the presence and intensity of different pollutants (heavy metals, chemical substances etc.) in air and soil in natural ecosystems as well as in the urban environments. The accumulation ...
Involvement of Na+/K(+)pump in fine modulation of bursting activity of the snail Br neuron by 10 mT static magnetic field
(Springer, New York, 2012)
The spontaneously active Br neuron from the brain-subesophageal ganglion complex of the garden snail Helix pomatia rhythmically generates regular bursts of action potentials with quiescent intervals accompanied by slow ...
The reaction of methionine with hydroxyl radical: reactive intermediates and methanethiol production
(Springer Wien, Wien, 2012)
The mechanisms of reaction of methionine with hydroxyl radical are not fully understood. Here, we unequivocally show using electron paramagnetic resonance spin-trapping spectroscopy and GC-FID and GC-MS, the presence of ...
Relevance of the ability of fructose 1,6-bis(phosphate) to sequester ferrous but not ferric ions
(Elsevier Sci Ltd, Oxford, 2011)
The cytoprotective activity of F16BP has been documented in severe conditions such as convulsions, reperfusion injury, septic shock, diabetic complications, hypothermia-induced injury, UV-provoked skin damage and in other ...
Biological activities of phenolic compounds and ethanolic extract of Halacsya sendtneri (Boiss) Dorfler
(De Gruyter Poland Sp Z O O, Warsaw, 2012)
The objective of this study was to evaluate the efficacy of the ethanolic extract of endemic plant Halacsya sendtneri in inhibiting the growing of the test fungi and bacteria as well as to determine its genotoxic potential ...
A Thermal Sensor for Water Using Self-Heated NTC Thick-Film Segmented Thermistors
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2011)
A simple thermal (heat loss) sensor system was designed in a small plastic tube housing using a negative thermal coefficient (NTC) thick-film thermistor as a self-heating sensor. The voltage power supply [range constant ...
