Optical absorption in molybdenum disulfide nanotubes
(Spie-Int Soc Optical Engineering, Bellingham, 2006)
Symmetry based calculations of the polarized optical absorption in single-wall MoS2 nanotubes are presented. Optical conductivity tensor for the individual tubes, using line group symmetry implemented POLSym code and ...
Activity and stability of soluble and immobilized alpha-glucosidase from baker's yeast in cosolvent systems
(Taylor & Francis Ltd, Abingdon, 2006)
The activity of alpha-glucosidase from baker's yeast was determined in various concentrations of dioxan, tetrahydrofuran, tert-butanol, dimethylformamide, methanol and dimethylsulfoxide (DMSO). Higher activities were ...
The influence of tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., ...
Photoacoustic and optical properties of zinc-stannate thin films
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Thin films of single-phase zinc-stannate (Zn2SnO4) were grown by rf magnetron sputtering onto glass substrates. Transmission in the visible range was measured allowing determination of the energy gap and thickness of ...
In vitro multiplication of willow gentian (Gentiana asclepiadea L.) and the production of gentiopicrine and mangiferin
(Phyton - Annales Rei Botanicae, 2006)
A protocol for in vitro propagation of Gentiana asclepiadea was developed. The best multiplication rate was obtained with woody plant medium (WPM) supplemented with 8.9 mu M BAP (6-benzylaminopurine) and 1.1 mu M IAA ...
Infrared properties of sintered α-MnSe
(Carl Hanser Verlag, 2006)
Far-infrared reflection spectra of sintered α-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak resulting ...
Senescence- and drought-related changes in peroxidase and superoxide dismutase isoforms in leaves of Ramonda serbica
(Oxford Univ Press, Oxford, 2006)
Ramonda sp. (Gesneriaceae) is an endemic and relic plant in a very small group of poikilohydric angiosperms that are able to survive in an almost completely dehydrated state. Senescence- and drought-related changes in the ...
Phenolic Compounds and Peroxidases in Sunflower Near-Isogenic Lines After Downy Mildew Infection
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Two near-isogenic lines of sunflower, resistant (+Pl6 gene) and susceptible (-P16 gene) to downy mildew were used in this paper. Secondary infection with a suspension of Plasmopara halstedii spores was done on the plants ...
Electrocatalytic activity of nano-sized Ebonex/Pt for underpotential deposition of hydrogen
(Trans Tech Publications Ltd, 2006)
The underpotential deposition of hydrogen was studied in 0.5 mol dm(-3) HClO4 solution on an electrode based on Ebonex-supported platinum electrocatalyst spread on rotation Au disk electrode (Ebonex/Pt). Pt catalyst was ...
Capacity of cerebrospinal fluid to transform hydrogen peroxide-relation to neurodegenerative changes in ALS
