Vacuum Fluctuations in Optical Metamaterials Containing Nonlinear Dielectrics
(Polish Academy of Sciences, 2009)
We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. ...
Fractal analysis of physical adsorption on surfaces of acid activated bentonites from Serbia
(Association of the Chemical Engineers of Serbia, 2008)
Solid surfaces are neither ideally regular, that is, morphological and energetically homogeneous, nor are they fully irregular or fractal. Instead, real solid surfaces exhibit a limited degree of organization quantified ...
Structures of Ni - Ni Nan contacts obtained by the electrode position in the presence of a magnetic field / Struktura nikal - nikal nanokontakta dobijenih elektrohemijskim taloženjem
(Belgrade, Serbia : Engineering Society for Corrosion, 2005)
Structures of Ni - Ni Nan contacts obtained by the electrode position at the different cathodic potentials were analyzed. Ni - Ni Nan contacts were electrodeposited from a Watt solution in the presence of coumarone, and ...
Radical reactions of xanthates: Annulation of the cyclopentene ring / Radikalske reakcije ksantata : anelacija ciklopentenovog prstena
(Belgrade : Serbian Chemical Society, 2007)
Homoallylic radicals, generated from the corresponding xanthates, react with terminal alkynes to give cyclopentene derivatives in moderate yields.
Magnetic effects in electrochemistry / Magnetni efekti u elektrohemiji
(Serbian Chemical Society, 2005)
The effect of imposed magnetic fields onto the electrodeposition of magnetic (nickel) and non – magnetic (copper) metals was analysed. Also, magnetic properties of electrochemically obtained nanocontacts were examined. An ...
Effect of temperature on the electrodeposition of disperse copper deposits / Uticaj temperature na elektrohemijsko taloženje disperznih taloga bakra
(Serbian Chemical Society, 2007)
The effect of temperature on the electrodeposition of copper at overpotentials belonging to the plateau of the limiting diffusion current density and higher was examined by the determination of the average current efficiency ...
The determination of quantitative jugolone content dynamics and the antioxidant activity in the extract of green walnut (Juglans regia L.) fruits / Određivanje dinamike kvantitativnog sadržaja juglona i antioksidativne aktivnosti u ekstraktu ploda mladog oraha (Juglans regia)
(Journal of Scientific Agricultural Research, 2007)
Fruits from three walnut cultivars were picked in three terms with the aim to determine the optimal harvesting time of green walnut fruits for the improvement fruit brandies. Quantity of juglone and its antioxidant activity ...
The roughness analysis of metal coatings by STM technique part IV: The relation between brightness and mechanisms of metal electrodeposition / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije IV deo - veza između sjaja i mehanizma elektrohemijskog taloženja metala
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work is given the analysis of roughness of copper coatings electrodepositedfrom a sulfate bath in the presence of modified polyglycol ether (Lutron H F 1), PEG 6000 and 3 - mercapto alkane sulfonate, by methodology ...
Electrochemically deposed Ni/W composite coatings obtained under constant and pulsating current regimes / Kompozitne Ni/WC prevlake dobijene elektrohemijskim taloženjem konstantnom i pulsirajućom strujom
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
The properties of composite coatings are dependent on properties of the base metal, as well as on properties of incorporating particles. The Ni / W composite coatings were obtained by electro deposition from commercially ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
