A new type of slow-wave PBG microstrip structures
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2002)
A consideration of fabrication-induced imperfections in photonic crystals for optical frequencies
(IEEE Computer Society, 2002)
We analyze fabrication-induced imperfections and disorder in our photonic crystals (PC) fabricated by microsystem technologies. Based on a correspondence between holograms and photonic crystals, we introduce technological ...
Ambient-temperature operation of nonequilibrium magnetoconcentration infrared detectors in InSb and HgCdTe
(IEEE Computer Society, 2002)
We present a theoretical and experimental consideration of magnetoconcentration-based long-wavelength infrared photodetectors with nonequilibrium Auger-process suppression, designed for room-temperature operation. Our ...
Hydride reduction of B-norcholestane 5α,6α-epoxide / Hidridna redukcija B-norholestan 5α,6α-epoksida
(Serbian Chemical Society, 2002)
B-Norcholestane epoxide 2 is reduced with lithium aluminium hydride to give either the 3β,6α-diol 3 or the corresponding 3β,5α-diol 4, depending on the quality of the reducing reagent employed. Aplausible mechanistic ...
Leucinaminopeptidaza soja, streptomyces hygroscopicus - izolovanje i karakterizacija
(Medicinski fakultet, Beograd, 2002)
Parameters optimization of acid activated bentonite clay from the coal mine 'Bogovina' / Optimizacija parametara kiselinske aktivacije bentonitnih glina iz RMU Bogovina
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, Beograd, 2002)
The bentonite clays, depending on the type of activation, are used as an adsorption media, as the starting material for the catalyst's supports, in the water purification processing plants, in the storage processing of ...
A novel lectin from the sponge Haliclona cratera: isolation, characterization and biological activity
(Elsevier Science Inc, New York, 2002)
A lectin from the Adriatic sponge Haliclona cratera was purified by ion-exchange and gel chromatography The molecular mass of the lectin is approximately 29 kDa. Purified lectin is rich in hydrophobic and basic amino acids ...
Methanol electrooxidation on supported Pt and Pt-Ru catalysts in acid and alkaline solutions
(Elsevier, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% PtRu (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
