SR-TXRF detection limit reduction using thin polymer film substrates

SR-TXRF Detection Limit Reduction Using Thin Polymer Film Substrates

Three different substrates for the analysis of liquid samples by Total Reflection X-Ray Fluorescence with Synchrotron Radiation (SR-TXRF) were investigated and compared: Lucite (Perspex), Kimfoil and Mylar. Dry targets were prepared by pipetting 5 μl aliquotes of the liquid samples (synthetic standards and fresh water samples) on the different substrates. A five fold reduction of the continuous...

Transparent, conductive ZnO:Al thin film deposited on polymer substrates by RF magnetron sputtering

In this paper, we present the optical, electrical, structural and mechanical properties exhibited by aluminum-doped zinc oxide (ZnO:Al) thin films produced by RF magnetron sputtering on polymeric substrates (polyethylene terephthalate, PET; Mylar type D from Dupont ) with a standard thickness of 100 mm. The influence of the uniaxial tensile strain on the electrical resistance of these films was...

Stability of an Evaporating Thin Polymer Film

Mesoscopic patterns have been observed to form in thin polymer films undergoing a fast dip-coating process. Though several mechanisms for creating of mesoscopic patterns have been proposed, the mechanism of the evaporation-induced mesoscopic self-organization is not yet fully understood. The paper aims to explain this phenomenon by studying the stability of a thin evaporating film. The analysis...
