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 ...
Photoacoustic determination of thermal and electron transport properties of single crystal NiO
(E D P Sciences, Les Ulis Cedex A, 2005)
Thermal and electron transport properties of single crystal NiO were determined using the photoacoustic technique. NiO single crystals were prepared using the Verneuil method and were easily cleaved parallel to the (100) ...
A phenomenological analysis of sintering kinetics of alumina
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper a phenomenological analysis of the sintering kinetics of alumina powder compacts with different proportions of small and large particles has been made. A phenomenological approach enables definition of ...
Spectral sensitivity of the dogfish shark (Scyliorhinus canicula)
(Springer, Dordrecht, 2007)
The action spectrum of the electroretinographic (ERG) b-wave and the unmasked late receptor potential (LRP) were measured under a variety of conditions (isolated eyecup, detached retina, b-wave recording in fresh preparations, ...
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 ...
Influence of carbohydrate source on Nepeta rtanjensis growth, morphogenesis, and nepetalactone production in vitro
(Brill Academic Publishers, Leiden, 2005)
A wide range of sucrose, fructose, and glucose levels in culture media was tested in vitro in order to determine those that provide optimum growth, morphogenesis, and the production of secondary metabolites in Nepeta ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer Heidelberg, Heidelberg, 2008)
A single p-type crystal of the mineral, pyrite ( FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic ( PA) amplitude and phase spectra were measured using a specially ...
Infrared properties of sintered alpha-MnSe
(Carl Hanser Verlag, Munich, 2006)
Far-infrared reflection spectra of sintered alpha-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 ...
An EPR spin-probe and spin-trap study of the free radicals produced by plant plasma membranes
(Srpsko hemijsko društvo, Beograd, 2005)
Plant plasma membranes are known to produce superoxide radicals, while the production of hydroxyl radical is thought to occur only in the cell wall. In this work it was demonstrated using combined spin-trap and spin-probe ...
Visualization of artificial lignin supramolecular structures
(Hindawi-Wiley, 2000)
In this paper we are presenting the results of our environmental scanning electron microscopy (ESEM) investigation of the lignin model compound-enzymatically polymerized coniferyl alcohol, also known as dehydrogenate polymer ...
