Résumé
La spectroscopie photoacoustique (PAS) et la spectroscopie par réflexion diffuse (DRS) nous ont servi à mesurer la concentration superficielle du cuivre à la surface de poudres de sulfure de zinc ou de blende. Les appareillages ont été préalablement testés sur un système modèle (colorants adsorbés sur de la silice).


Abstract
Photoacoustic spectroscopy (PAS) and diffuse reflectance spectroscopy (DRS) have been used to get the surface concentration of copper on powders of zinc sulfide or sphalerites. Spectrometer were first tested on a model system (dyes adsorbed on silica).





What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
