Gradient analysis reveals a copper paradox on floodplain soils under long-term pollution by mining waste
(Elsevier, Amsterdam, 2012)
Arable alluvial soils are a globally important resource under increasing pressure from both industrial pollution and intensified agricultural land use. Quality of agricultural soils is ultimately defined by crop yields; ...
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% ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solution. Chemical composition, phase composition and morphology effects
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work the hydrogen evolution reaction (HER) onto Ni-Sn alloy coatings deposited at different current densities from the bath containing 0.1 M Sn2+ and 0.1 M Ni2+ ions in the pyrophosphate-glycine solution, was ...
Service life test of non-noble metal composite cathodes for hydrogen evolution in sodium hydroxide solution
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work polarization characteristics and "service life" test of the non-noble metal composite coatings Ni-MoOx and Ni-MoO2 for hydrogen evolution reaction (HER) in 32 wt.% NaOH at 90 degrees C were investigated and ...
Study of the covalently immobilized amyloglucosidase on macroporous polymer by mathematical modeling of the pH optima
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: A totally new approach has been applied for mathematical modeling of the enzyme activity/pH relationship, for quantification and distribution of enzyme activity in and out of carrier pores. This is a very simple ...
Surface tip-to-base Ca2+ and H+ ionic fluxes are involved in apical growth and graviperception of the Phycomyces stage I sporangiophore
(Springer, New York, 2012)
Net fluxes of Ca2+ and H+ ions were measured non-invasively close to the surface of Phycomyces blakesleeanus sporangiophores stage I using ion-selective vibrating microelectrodes. The measurements were performed on a wild ...
Improvement of barium titanate properties induced by attrition milling
(Elsevier Sci Ltd, Oxford, 2012)
Barium titanate powder was prepared by soft chemical process from polymeric precursors (modified Pechini process). The synthesized barium titanate (BT) powder was nanosized and the factor of agglomeration (F-agg) pointed ...
Use of Chenopodium murale L. transgenic hairy root in vitro culture system as a new tool for allelopathic assays
(Elsevier Gmbh, Munich, 2012)
We investigated Chenopodium murale transgenic hairy root in vitro culture system as a new tool for allelopathic assays. Transgenic hairy roots were induced by Agrobacterium rhizogenes A4M70GUS from roots, cotyledons, leaves, ...
Structural organisation of the wood polymers in the wood fibre structure
(BioResources, 2012)
The organization of the major polymers in the wood fiber has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, providing the longitudinal strength ...
Contribution of inorganic cations and organic compounds to osmotic adjustment in root cultures of two Centaurium species differing in tolerance to salt stress
(Springer, Dordrecht, 2012)
The effect of reduced availability of sugars on growth and essential metabolic processes in roots, resulting from decreased photosynthesis under salinity, was excluded by establishing a non-photosynthetic model-system in ...
