The properties of a thin sheet of poly(dimethylsiloxane) (PDMS) membrane as an extraction phase were examined and compared to solid-phase microextraction (SPME) PDMS-coated fiber for application to semivolatile analytes in direct and headspace modes.

Ferroelectric Thin Films and Thin Film Devices
1993Research and development efforts on ferroelectric memories have been underway since about 1955. The early work, largely at IBM, RCA, Bell Telephone Laboratories and other US industrial laboratories was stymied by two problems: Firstly, the materials were too thick to permit operation at 5 V, the standard “TTL” or “CMOS” operating voltages in the ...

Summary form only given. A very wide range of both vapor- and liquid-phase deposition techniques were applied to produce crystalline films of composition in a lead zirconate:lead titanate solid solution system. At compositions close to the morphotropic phase boundary, a regimen which shows excellent piezoelectric properties in the bulk ceramic films ...

A discussion of the difficulties of measuring adhesion. Results obtained by various methods are critically considered in the light of theoretical and other estimates of the magnitude to be expected. New ideas on scratch testing are presented and some of the difficulties associated with this method are discussed. For measuring the adhesion of thin films,

Thin films1 possess two radically distinct typical scales associated with their transverse and their longitudinal dimensions. Two distinct dynamics are thus associated to these length scales: transverse or longitudinal dispersive waves linked to the film thickness, and longitudinal quasi-two-dimensional (2D) motion scaling on the film length.

Thin-film thermopiles in microcalorimeters
Sensors and Actuators A: Physical, 1991Abstract Microcalorimeters are special devices used for effective efficiency measurements of bolometric power sensors. The performance of the microcalorimeters, such as their sensitivity and accuracy, is mainly dependent on the thermoelectric detector.

CdTe and CuIn1−xGaxSe2−ySy (CIGSS) are ideal candidates for thin-film solar cells. Present photovoltaic (PV) conversion efficiencies of champion thin-film solar cells are: CuIn1−xGaxSe2 (CIGS) 19.5%, CdTe 16.5%, and a-Si:H 12.4%. Thin-film PV modules could spearhead production growth of photovoltaics in the United States because of their added ...

Publisher Summary This chapter discusses the thin film dialysis with respect to theory, experimental methods, applications in preparative and analytical work, and the future of the technique. If a solution is dialyzed, its components are subjected to separation processes that are based upon differential diffusion rates through a semipermeable ...

Journal of Crystal Growth, 1986
The periodic cracking technique for determining the work of adhesion of thin metallic films was applied to two different substrate systems which were metallic substrates (Al, Cu and steel sheet) and a polymeric substrate (ABS, acrylonitrile butadiene styrene). The original model assumes elastic behaviour of the composite and is insufficient for such an
