Electrochemical deposition and characterization of Zn /Co alloys and corrosion protection by electrodeposited epoxy coating on Zn /Co alloy
(Elsevier, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
The application of modified macroporous poly(GMA-co-EGDMA) in the metal ions sorption from aqueous solutions / Primena modifikovanog makroporoznog poli(GMA-co-EGDMA) kopolimera u sorpciji jona metala iz vodenih rastvora
(Tehnika - Novi materijali, 2002)
Macro porous cross linked poly(GMA-co-EGDMA) copolymer synthesized by radical suspension copolywerization was modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine, EDA. Sorption capacities ...
Photooxidation of n-heptanal in air: Norrish type I and II processes and quantum yield total pressure dependency
(Royal Society of Chemistry, 2002)
Dilute mixtures of n-heptanal in synthetic air (up to 100 ppm) were photolyzed with fluorescent UV lamps (275-380 nm) at 298 K. The main photooxidation products, identified and quantitatively analyzed by FTIR spectroscopy, ...
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 ...
The retention behaviour of some cholic acid derivatives on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2002)
The thin-layer chromatographic behavior of cholic acid and fourteen of its synthetic derivatives has been studied in six reversed-phase and three normal-phase systems. Four significantly different adsorbents were used - ...
Mixed steroidal 1,2,4,5-tetraoxanes: Antimalarial and antimycobacterial activity
(American Chemical Society (ACS), 2002)
Mixed 1,2,4,5-tetraoxanes possessing simple spirocycloalkane and spirocholic acid-derived substituents were prepared and shown to have significantly higher in vitro antimalarial activity than bis-substituted tetraoxanes. ...
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 ...
Adsorption-desorption noise in micromechanical resonant structures
(Elsevier, 2002)
In this paper we analyze adsorption-desorption (AD) noise in resonant microelectromechanical structures. This noise is generated by instantaneous differences in the rates of adsorption and desorption of contaminant molecules ...
Polysulfone membranes for ultra and microfiltration / Polimerne membrane za ultra i mikrofiltraciju na bazi polisulfona
(Tehnika - Novi materijali, 2002)
The influence of the propionic acid as nonsolvent additive on the properties of the prepared polysulfone membranes was investigated. The obtained results show that the membranes prepared from the polymer solutions with ...
