International Classification:

G01N 1508

US Classification:

73 38

Abstract:

The Invention concerns an apparatus for and method for the simultaneous determination of permeation rate through and desorption rate from a polymeric specimen, the method comprising sealingly separating a first volume from a second volume with a specimen to be tested, said specimen being suffused with a first isotope of a gas or vapor; introducing in said first volume a second isotope of said gas or vapor, said second isotope being detectably distinguishable from said first isotope; in said second volume, adjusting the partial pressure of both said isotopes of said gas or vapor to a negligible value compared to that of said second isotope of said gas or vapor in said first volume; and, distinguishably detecting the concentration of each said diffusing isotope of said permeant in said second volume.

Abstract:

The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.
