Threshold voltage in MOSFETs and MODFETs as a problem of nonlinear dynamics
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
A widely known (and also very well examined) problem of threshold voltage in MOSFETs and MODFETs has been described with the tools of nonlinear dynamics. Some interesting features of such devices have been derived, together ...
A Comparative LSER Study of the Reactivity of 2-Substituted Cyclohex-1-eneacetic and 2-Substituted Phenylacetic Acids with Diazodiphenylmethane in Various Solvents
(Wiley, Hoboken, 2009)
The rate constants for the reaction of 2-substituted cyclohex-1-eneacetic and 2-substituted phenylacetic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 degrees C. To explain the kinetic ...
Electrochemical and sorption characteristics and thermal stability of epoxy coatings electrodeposited on steel modified by Zn-Co alloy
(Elsevier Science Sa, Lausanne, 2002)
The corrosion behaviour, transport properties and thermal stability of epoxy coatings electrodeposited on steel and steel modified by Zn-Co alloys were investigated during exposure to 3% NaCl solution. The electrochemical ...
Study of the kinetics and the influence of Bi-irr, on formic acid oxidation at Pt2RU3/C
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HCIO4 solutions was examined on thin film Pt2RU3/C electrode. XRD pattern revealed that Pt2RU3 alloy consisted of the solid solution of Ru in Pt and the small amount of Ru ...
Estimate of Si3N4 diffusion into Cu based filler metal
(Elsevier Science Ltd, 2000)
The diffusion phenomena occurring at the boundary between Si3N4 and active Cu based filler metal during Si3Nn/metal joining are discussed as a part of the general theory of reaction layer growth. The mechanism of reaction ...
Lipase-catalyzed synthesis of biodiesel in solvent-free system with different acyl acceptors
(Elsevier Science Bv, Amsterdam, 2009)
Synthesis and characterization of interpenetrating polymer networks with hyperbranched polymers through thermal-UV dual curing
(Elsevier Science Sa, Lausanne, 2008)
The aim of this study was to investigate the possibility of using acrylated hyperbranched polyesters (HBP) as UV curable component in dual curing automotive applications. Dual curing is one of possible ways to obtain fast ...
Influence of Hydrolysis on the Osmotic Coefficients of the System {yZnCl(2) + (1-y)ZnSO4}(aq) at Temperature 298.15 K
(Amer Chemical Soc, Washington, 2009)
Isopiestic vapor pressure measurements were made for {yZnCl(2) + (1 - y)ZnSO4}(aq) solutions with ZnCl2 ionic strength fractions of y = (0.2640, 0.5042, 0.7533, and 1) at the temperature 298.15 K, using KCl(aq) as the ...
Design of the Switching Controller for the High-Capacity Non-Blocking Internet Router
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2009)
The sequential greedy scheduling (SGS) algorithm is a scalable maximal matching algorithm. This algorithm was conceptually proposed and well received since it provides non-blocking in an Internet router with input buffers ...
Oxygen reduction reaction on Pt(111): effects of bromide
(Elsevier Science Sa, Lausanne, 1999)
Using the rotating ring-disk technique (RRDE) the oxygen reduction reaction (orr) was studied on the Pt(111) surface in the presence of Br- anions. We found that the orr at the Pt(111) \ Br-ad interface is always accompanied ...
