    Comparison between decolorization of denim fabrics with Oxygen and Argon glow discharge

    , Article Surface and Coatings Technology ; Volume 201, Issue 9-11 SPEC. ISS , 2007 , Pages 4926-4930 ; 02578972 (ISSN) Ghoranneviss, M ; Shahidi, S ; Moazzenchi, B ; Anvari, A ; Rashidi, A ; Hosseini, H ; Sharif University of Technology
    In this study, we have used a low temperature plasma, produced by a DC magnetron sputtering device, for decolorizing of denim fabrics, and the effect of using different gases such as Argon and Oxygen as the discharge medium have been investigated. The results obtained under equal periods of time have been compared and the effect of washing on the treated denims has been reported. © 2006 Elsevier B.V. All rights reserved  

    Decolorization of denim fabrics with cold plasmas in the presence of magnetic fields

    , Article Plasma Processes and Polymers ; Volume 3, Issue 3 , 2006 , Pages 316-321 ; 16128850 (ISSN) Ghoranneviss, M ; Moazzenchi, B ; Shahidi, S ; Anvari, A ; Rashidi, A ; Sharif University of Technology
    Denim jeans have consistently been fashionable around the world. This fabric inspired strong opinions from historians, teenagers, and movie stars, and has acquired different styles throughout the years. Most jeans today are stonewashed; this technique first become popular in 1970. Now, in addition to pumice stones, enzymes are used on the cotton fabrics to create the stonewashed look. Nowadays, plasma treatment is a cost-effective and environment-friendly process which is able to modify the properties of the fabric surface in order to achieve this effect. Plasma surface treatment changes the properties of the fabric up to a limited depth (several molecular layers), leaving the bulk... 

    An analytical model of plasma cavity for producing of quasi-monoenergetic electron in intense laser-plasma interaction

    , Article 34th European Physical Society Conference on Plasma Physics 2007, EPS 2007, Warsaw, 2 July 2007 through 6 July 2007 ; Volume 31, Issue 3 , 2007 , Pages 1773-1776 ; 9781622763344 (ISBN) Zobdeh, P ; Sadighi Bonabi, R ; Afarideh, H ; Sharif University of Technology
    During the recent experiments and PIC simulations, quasi-monoenergetic for electron is observed [1, 2]. Forming the free of cold plasma electrons cavity behind the laser pulse is possible instead of periodic plasma wave and plasma channel guided method [3]. In this bubble cavity a dense bunch of relativistic electrons with a monoenergetic spectrum is self-generated [3].The profiles [3] and PIC simulation [4] show the ellipsoid shape cavity behind the laser pulse. In this work we present an analytical ellipsoid model and discuss how quasi-monoenergetic electron is produced in the bubble field
