Fishnet-Based Metamaterials: Spectral Tuning Through Adsorption Mechanism
(Polish Academy of Sciences, 2009)
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated ...

The paper presents the testing and analysis of the characteristics of furnace which is previously used in the semiconductor industry. With the changes that have been analyzed, has become a part of the equipment to view ...
Analysis and improvement of production transmitters in IHTM / Analiza i unapređenje proizvodnje transmitera u IHTM-u
(Tehnika - Mašinstvo, 2009)
In this paper analyzes the technology of production of these IHTM transmitters in relation to the other side of competition. QFD analysis gives us the direction to be moving production of local transmitters. Foreign ...
Quantitative analysis of sesquiterpene lactone cnicin in seven Centaurea species wild-growing in Serbia and Montenegro using 1H-NMR spectroscopy / Kvantitativna analiza seskviterpenskog laktona knicina u sedam samoniklih biljnih vrsta roda Centaurea, koje rastu u Srbiji i Crnoj Gori, korišćenjem 1H-NMR
(Serbian Chemical Society, 2007)
1H-NMR spectroscopy was applied for the quantitative analysis of cnicin, a bioactive germacranolide type sesquiterpene lactone, in the aerial parts of seven wild-growing Centaurea species collected in Serbia and Montenegro. ...
Regioselectivity of conjugate additions to monoalkyl-1,4-benzoquinones / Regioselektivnost konjugovane adicijena monoalkil-1,4-benzohinone
(Serbian Chemical Society, 2002)
The regioselectivity of the reaction of conjugate addition of thiols amines, methanol and hydrogen chloride with the monoalkyl-1,4-benzoquinones avarone and 2-tert-butyl- 1,4-benzoquinone was investigated. It was shown ...
Ethyl 3-(6-phenyl-44-1,2-dithiolo[1,5-b][1,2,4]dithiazol-2-yl) propanoate
(International Union of Crystallography, 2008)
The title compound, C15H15NO2S3, exists in a bicyclic form, with resonance contributions from two monocyclic forms, each without a second S - S bond. The trithiapentalene heterocyclic ring system is planar, with a mean ...
The effect of perpendicularly oriented magnetic field on the formation of very disperse iron structures / Uticaj vertikalno orijentisanog magnetnog polja na formiranje veoma disperznih struktura gvožđa
(Serbian Chemical Society, 2006)
Iron deposits obtained without and with a perpendicularly oriented magnetic field were examined by scanning electron microscopy (SEM). It was found that the iron deposit obtained under a perpendicularly oriented magnetic ...
Evaluation of saturated and aromatic hydrocarbons oil-oil maturity correlation parameters (SE Pannonian Basin, Serbia) / Евалуација матурационих параметара заснованих на засићеним и ароматичним угљоводоницима у корелацији нафта-нафта (југоисточни део панонског басена , Србија)
(Belgrade : Serbian Chemical Society, 2007)
Twenty three crude oils from the Serbian part of the Pannonian Basin (14 from the Vojvodina Province and 9 from the Drmno Depression) were investigated, aimed at an evaluation of oil-oil maturity correlation parameters ...
Evidence of stability of sedimentary organic matter during bacterial desilicification of an oil shale / Dokaz o postojanosti sedimentne organske supstance pri bakterijskoj desilicifikaciji jednog uzorka bituminoznog škriljca
(Serbian Chemical Society, 2001)
Aleksinac oil shale organic matter appeared to remain unchanged, according to elemental, IR, P-GC and P-GC-MS analytical characterization, after exposure to Bacillus circulans-Jordan desilicification for 30 days. These ...
Adhesion of epoxy cataphoretic coatings on Zn alloys / Адхезија епоксидних катафоретских превлака на легурама цинка
(Belgrade : Serbian Chemical Society, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of coating adhesion under environmental influence. In this work, the adhesion of epoxy cataphoretic coatings was examined on steel ...
