Deconvolution of lignin fluorescence spectra: A contribution to the comparative structural studies of lignins
(Maik Nauka/Interperiodica/Springer, New York, 2007)
In this work, we deconvoluted the fluorescence spectra of lignin and a lignin model compound using a combination of one symmetric ( Gaussian) and the most appropriate number of asymmetric (Log-normal) models. We aimed to ...
Characterization of polyphenol oxidase changes induced by desiccation of Ramonda serbica leaves
(Wiley, Hoboken, 2008)
Resurrection plants are able to dehydrate/rehydrate rapidly without cell damage by a mechanism, the understanding of which may be of ecological importance in the adaptation of crop plants to dry conditions. The o-diphenol ...
Fabrication of proton conducting solid oxide fuel cell by using electrophoretic deposition
(ECS Transactions, 2009)
Anode-supported proton conducting solid oxide fuel cells (SOFCs) were fabricated by using electrophoretic deposition (EPD) for the electrolyte film deposition. BaCe0.9Y0.1O3-δ (BCY10) thick films were deposited on NiO-BCY10 ...
EM Simulator Analysis of Optimal Performance Thick-Film Segmented Thermistors versus Material Characteristics Selection
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2008)
In this paper, an alternative approach to the analysis of thick-film segmented negative temperature coefficient thermistors based on the use of a commercial electromagnetic simulator tool is presented. The influence of the ...
Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Trans Tech Publications Ltd, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
Incidence and Distribution of Iris yellow spot virus on Onion in Serbia
(Amer Phytopathological Soc, St Paul, 2009)
In a survey to determine the presence and distribution of It-is yellows, spot virus (IYSV) in greenhouse ornamentals and onion field crops in 14 districts of Serbia as well as on imported ornamental plants, 1,574 samples ...
Effect of traffic on the soil contamination with polycyclic aromatic hydrocarbons (PAHs)
(Taylor & Francis Ltd, Abingdon, 2008)
The level of the environment pollution with polycyclic aromatic hydrocarbons is mainly in correlation with degree of the region industrialization and the traffic density. The aim of this study was to determine the effect ...
Synthesis and characterization of ceria based nanometric powders
(Elsevier Science Bv, Amsterdam, 2009)
Nanopowdered solid solution Ce(1-x)Fe(x)O(2-delta) samples (0 lt = x lt = 0.1) were synthesized by a self-propagating room temperature synthesis (SPRT). XRD and Raman spectroscopy at room temperature were used to study ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb(0.9)Sn(0.1)Te doped with 0.4 ...
Far infrared properties of sintered Pb0.9Sn0.1Te doped with palladium
(Springer, New York, 2009)
Far infrared reflectivity spectra of sintered Pb0.9Sn0.1Te doped with 0.2 and 2 at.% Pd are measured. The experimental results are analyzed using a fitting procedure based on a modified plasmon-phonon interaction model. ...
