High Activity and Stability of Pt2Bi Catalyst in Formic Acid Oxidation
(Springer, New York, 2012)
Formic acid oxidation was studied on a new prepared Pt2Bi characterized by X-ray diffraction spectroscopy (phase composition), scanning tunneling microscopy (STM) (surface morphology), and COads stripping voltammetry ...
N-type silicon electron mobility and its relationship to the kink effect for nano-scaled SOI NMOS devices
(Materials Science Forum, 2007)
Electron mobility for the silicon-based devices is one of the most important parameters, which determine the behavior of components. Mobility depends on silicon purity, doping level, presence of lattice defects and electric ...
Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Materials Science Forum, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
Reduction of Oxygen at a NaX-Ag Composite Electrode and Its Application to the Determination of Oxygen in Aqueous Media
(Maik Nauka/Interperiodica/Springer, New York, 2010)
A composite mixture Ag-NaX zeolite (silver concentration 16.7% w/w) is synthesized usingimpregnation and thermal decomposition. For silver impregnation, a solution of an Ag acetylacetonate complex in acetone was used. ...
Wide Band-stop Microwave Microstrip Filter on High-resistivity Silicon
(Soc Microelectronics, Electron Components Materials-Midem, Ljubljjana, 2012)
Low-resistivity silicon (standard CMOS-grade silicon) is a troublesome issue for the microwave passive components. One solution is using high-resistivity silicon (HRS). Wide band-stop filter on high-resistivity silicon ...
Applicability of the lean concept to the management of small-scale manufacturing enterprises in Serbia
(Slavonski brod : Faculty of Mechanical EngineeringOsijek : Faculty of Electrical EngineeringOsijek : Faculty of Civil Engineering, 2017)
Lean management (LM) is a set of procedures and principles used in industrial processes for finding and eliminating useless activities. This paper presents the analysis of business practices in small-scale manufacturing ...
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 ...
Whether integrating refining and petrochemical business can provide opportunities for development of petrochemical industry in Serbia / Da li integrisanje rafinerijskog i petrohemijskog biznisa pruža mogućnost za razvoj petrohemijske industrije u Srbiji
(Serbia : Association of Chemists and Chemical Engineers of Serbia, 2016)
Since the beginning of 90s of last century both the petroleum industry and petrochemical industry have operated in difficult circumstances. In particularly, margins of petroleum and petrochemical industry were exacerbated ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
