Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Taylor & Francis Ltd, Abingdon, 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
Capacity of cerebrospinal fluid to transform hydrogen peroxide-relation to neurodegenerative changes in ALS
(Taylor & Francis Ltd, Abingdon, 2006)
Light-induced transient ion flux responses from maize leaves and their association with leaf growth and photosynthesis
(Wiley, Hoboken, 2005)
Net fluxes of H+, K+ and Ca2+ ions from maize (Zea mays L.) isolated leaf segments were measured non-invasively using ion-selective vibrating microelectrodes (the MIFE technique). Leaf segments were isolated from the blade ...
Spectral and dose dependence of light-induced ion flux responses from maize leaves and their involvement in leaf expansion growth
(Oxford Univ Press, Oxford, 2007)
Two types of segments (intact leaf tissue and isolated mesophyll tissue respectively) were isolated from basal (still growing) and tip (non-growing) maize leaf regions. The leaf segments were exposed to different light ...
Infrared reflection spectroscopy of Zn2SnO4 thin films deposited on silica substrate by radio frequency magnetron sputtering
(Elsevier Science Sa, Lausanne, 2008)
Single-phase zinc-stannate thin films of different thickness values were prepared by radio frequency magnetron sputtering on a silica substrate. Rietveld analysis of X-ray diffraction data confirmed that the films had an ...
Tailoring of morphology and orientation of LaNiO3 films from polymeric precursors
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to prepare lanthanum nickel oxide (LaNiO3, LNO) thin films of different morphology and orientation. The precursor solutions were prepared by a chemical method from citric salts of lanthanum and ...
Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
Electronic and transport properties of contacts between molybdenum sulfide nanowires and gold electrodes
(Amer Inst Physics, Melville, 2008)
We report unique electronic and transport properties of contacts between a molybdenum sulfide nanowire and a gold electrode. The pointlike contacts exhibit a remarkable transparency for the charge carrier injection, which ...
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 ...
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 ...
