Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Elsevier Science Sa, Lausanne, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Efekat neurotoksičnosti aluminijuma na elektrokortikalnu aktivnost mozga pacova / Effect of aluminium neurotoxicity on the rat brain electrocortical activity
(Acta biologica serbica - serija C: Acta physiologica et pharmacologica serbica, 2006)
The aim of our study was to investigate the electrophysiological effects of aluminium neurotoxicity. This animal model of neurodegenerative dementia was induced by chronic treatment of Wistarrats with aluminum chloride for ...
Anomalous lateral beam shift and total absorption due to excitation of surface waves in materials with negative refraction
(EUROPEAN PHYSICAL JOURNAL D, 2006)
We studied electromagnetic beam reflection from layered structures that include materials with negative refraction. Excitation of leaky surface waves leads to the formation of anomalous lateral shifts in the reflected beams ...
Cerium Oxide Based Nanometric Powders: Synthesis and Characterization
(Science of Sintering, 2007)
Nanometric powders of solid solutions of cerium oxide were obtained by a modified
glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more
dopants in the lattice were synthesized. Rare earth ...
Changes in activities of antioxidant enzymes during Chenopodium murale seed germination
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2008)
The activities and isoenzyme pattern of catalase (CAT), superoxide dismutase (SOD) and peroxidase (POD) have been studied during germination of Chenopodium murale seeds. CAT and SOD activities were similar in dry seeds and ...
Guided modes in left-handed waveguides
(OPTICS COMMUNICATIONS, 2008)
We investigate basic properties of linear guided modes in a waveguide slab with the core of a material with simultaneously negative effective permittivity and permeability surrounded by a normal dielectric cladding. The ...
Role of fructose in the adaptation of plants to cold-induced oxidative stress
(Springer, New York, 2008)
This work presents findings, which indicate important role of fructose, fructose 6-phosphate (F6P), and fructose 1,6-bisphosphate (FBP) in preservation of homeostasis in plants under low temperature. Cold combined with ...
Oxalate oxidase and non-enzymatic compounds of the antioxidative system in young Serbian spruce plants exposed to cadmium stress
(Srpsko biološko društvo, Beograd, i dr., 2008)
We studied changes in the concentrations of ascorbate and glutathione, composition of soluble phenolics, and activity of oxalate oxidase in 75-day-old Serbian spruce plants after exposure to 5 mu M and 50 mu M cadmium for ...
