Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni+WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WCparticles, ...
The Human Intestinal Microbiota and Its Impact on Human Health
(ASM Press, 2008)
Mechanism of electrical breakdown of gases for pressures from 10 -9 to 1 bar and inter-electrode gaps from 0.1 to 0.5 mm
(Institute of Physics Publishing, 2007)
This paper discusses the mechanisms of gas breakdown at low values of pressure and inter-electrode gap, i.e. in the vicinity of the Paschen minimum. In this area of pressure and inter-electrode gap values, breakdown occurs ...
Chitosan application on wool before enzymatic treatment
(Wiley Periodicals, Inc., 2005)
The influence of a chitosan application on wool fabric before a treatment with a proteolytic enzyme has been investigated. The enzymatic treatment enhances whiteness and confers shrink resistance to wool, but an increase ...
Gamma irradiation effects in programmable read only memories
(Institute of Physics Publishing, 2007)
This paper examines the reliability of commercial off the shelf (COTS) erasable programmable read only memory (EPROM) and electrically erasable programmable read only memory (EEPROM) components exposed to gamma radiation. ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
Advanced Sorbent Materials for Treatment of Wastewaters
(Springer-Verlag Berlin Heidelberg, 2008)
Despite the existence of a wide range of wastewater treatment technologies, sorption is still commonly applied for the purification of industrial effluents. This is particularly valid for textile industry effluents, where ...
Excess molar volumes of N-methylacetamide + tetrahydrofuran, +2-butanone, +ethylacetate at the temperatures between 303.15 K and 318.15 K
(Elsevier, 2005)
Excess molar volumes, V m E , of N-methylacetamide (NMA) + tetrahydrofuran (THF), NMA + 2-butanone (B) and NMA + ethylacetate (EA) have been determined at the temperatures: 303.15 K, 308.15 K, 313.15 K, 318.15 K. The results ...
Flow boiling of R134a and ammonia in a plate heat exchanger
(Elsevier Ltd, 2008)
This paper presents experimental results on evaporation heat transfer for flow boiling of ammonia and of R134a in a chevron-pattern corrugated plate heat exchanger (PHE). The measurements enable the evaluation of a quasi-local ...
STM image visualization of Si(111) 7 x 7 surface (graphic simulation and implementation)
(Elsevier Science Bv, Amsterdam, 2007)
The possibilities of graphic STM image simulation of a clean Si(1 1 1) 7 x 7 surface at atomic level are indicated. The presented procedure takes into account various types of deformation on the surface near the Fermi level ...
