The collaboration between Sharp Laboratories of America (SLA), Oregon State University (OSU) and ORNL focused on low thermal budget pulse thermal processing (PTP) technique to develop high performance copper zinc tin sulfide (CZTS) thin film system for advanced photovoltaic (PV) applications, with the goal to develop novel fabrication processes for the manufacture of low-cost, high-performance ...

This paper reports results from electrical and thermal conduction measurements carried out on the DNA-gold composite for which the overall conduction is shown to be dominated by the DNA rather than the discontinuous gold coatings. The electrical and thermal conductivities of the composite were about 14 S/cm and 150 W/(m K) at room temperature, respectively. The resulting value of 3.6 x 10(-4) W...

Thermal barrier coatings (TBC) are used widely on a range of components that operate at high temperatures. We report measurement of the factor that is required to convert the Raman shift to stress for air plasma sprayed yttria (7 wt %) stabilized tetragonal zirconia (ZrO(2)) (YSZ) thermal barrier coatings. The factor is evaluated for the as-coated condition and also following a heat treatment a...

The aim of this work was to prepare hydroxyapatite coatings (HAp) by a sol-gel method on Ti6Al4V alloy and to study the bioactivity, biocompatibility and corrosion protection behaviour of these coatings in presence of simulated body fluids (SBFs). Thermogravimetric/Differential Thermal Analyses (TG/DTA) and X-ray Diffraction (XRD) have been applied to obtain information about the phase transfor...

Solar thermal absorber coatings play an important role in the opto-thermal efficiency of receivers Concentrated Power (CSP). Two standard figures merit are solar absorptance ?sol and emittance ?th, derived from spectral directional hemispherical reflectance measurements at room temperature. These two allow comparing coating formulations terms performance durability. In this study, a black selec...

The microstructural analysis of Thermal Barrier Coatings, deposited according to the Air Plasma Spray technology, furnishes information according which a strong orthotropic thermal conductivity is expected to be measured for such a material. Pulsed experiment with a localized heating source and thermographic temperature recording, permit to evaluate both the in-depth and in-plane components of ...

The microstructure and local mechanical characteristics of thermal spray ferrous coatings have been determined. The emphasis has been on coatings made by the high velocity oxyfuel (HVOF) process, especially the role of Al alloy additives. The oxide phase present in the material and preferred pathways for local cracking and separation have been determined. Thin intersplat oxide layers emerge as ...

Inkjet–printing technology was used to apply biodegradable and biocompatible polymeric coatings of poly(D, L lactide) with the antiproliferative drugs simvastatin (SMV) and paclitaxel (PCX) on coronary metal stents. A piezoelectric dispenser applied coating patterns of very fine droplets (300 xL) and ink jetting was optimized to develop uniform, accurate and reproducible coatings of high yields...
