Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Materials Chemistry and Physics, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl and 0.25 mol dm-3 aniline monomer. ...
Corrosion behavior of magnesium, aluminum and zinc as anodic materials in chloride based electrolytes for use in primary and secondary electrochemical power sources
(Elsevier Sci Ltd, Oxford, 2009)
Corrosion behavior of magnesium, aluminum and zinc in 0.2 mol dm(-3) NH4Cl; 0.1 mol dm(-3) NH4Cl with addition of 0.1 mol dm(-3) Na-citrate and corrosion behavior of zinc in 0.3 mol dm-3 NH4Cl with addition of 0.8 mol ...
Investigation of ion-beam modified silicon by photoacoustic method
(IEEE Computer Society, 2000)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...
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 ...
Review of our beneficiation of oil shale by bioprocessing on laboratory scale
(International Oil Shale Symposium, Tallin, Estonia, 8-11 June 2009, 2009)
It is estimated that reserves of oil shale in Serbia amounts to about 3 billion tons while the largest deposit (approx. 2/3 of total amount) for open-pit and underground exploitation is situated in the locality of Aleksinac ...
Influence of carrier diffusion on the response of a resonant-cavity enhanced detector
(IEEE Journal of Quantum Electronics, 2002)
We have investigated the effects of carrier diffusion on the impulse response of a resonant-cavity enhanced photodetector using our analytic expression for a short-circuit current. Our theoretical results indicate that ...
Antenna solution for future communication devices in mm-wave range
(IEEE Computer Society, 2001)
Different types of printed antennas for millimeter ranges such as high gain (narrow beam) with linear and circular polarization, sector antennas with azimuth angle of 60°, 90° and 180°, and omnidirectional antennas are ...
Photo-pyro-piezo-electric elastic bending method: Investigation of metalsemiconductor structure
(IEEE Computer Society, 2002)
The metal-semiconductor (MS) junction is investigated by new method based on two techniques: the acphotovoltage and pyro-piezo-electric technique. The sample with metal-semiconductor-metal configuration was attached to the ...
Silicon resonant cavity enhanced UV flame detector
(IEEE Computer Society, 2002)
The need for selectively sensitive UV photodetectors poses a requirement both for novel detector structures and for new materials and technologies to produce them. In this paper we consider, for the first time, a possibility ...
A novel analytical model of a SiC MOSFET
(IEEE Computer Society, 2002)
This paper presents a novel analytical model for simulation of characteristics of a n-channel MOSFET based on silicon-carbide (SiC). Using known experimental results, a semiempirical relation for carrier mobility (/spl ...
