Solution-cast coating films of perchlorate-doped oligo(3-methoxythiophene) exhibited a gold-like luster similar to that metallic gold despite the involvement no metals. However, development mechanism remains ambiguous. To understand mechanism, we performed scanning electron microscopic analysis, variable-angle spectral reflectance measurements, and ellipsometry measurements on ClO4−-doped cast ...

The aim of this study was to characterize a conventional and a pressed porcelain for zirconia core as to biaxial flexural strength (BFS), apparent fracture toughness (FT) and microstructure composition, and to investigate the effect of glaze cooling rate on the BFS of the zirconia/porcelain bilayers. Monolayers of conventional porcelain Vita VM9 and pressed porcelain Vita PM9 (n=15) (12 mm diam...

In August 1992, a physician notified the Alaska Division of Public Health (ADPH) that three patients at a psychiatric hospital had consumed ceramic glaze during ceramic therapy (i.e., recreation therapy involving the production of ceramic ware), and two of these patients had elevated blood lead levels (BLLs). This report summarizes the ADPH's investigation of these ingestions.

PURPOSE The purpose of this in vitro research project was to evaluate and compare the wear behavior of human tooth enamel opposing monolithic zirconia and other different ceramic restorative materials and also to observe the tetragonal to monoclinic phase transformation in zirconia-based ceramics that may occur while simulating wear occurring at room temperature in a wet environment. MATERIAL...

The summer headscarves, which are usually made of polyester, commonly used by women in the Middle East and South Asia regions. polyester fibers provide good luster drape but give poor comfort to wearer. This work aims produce headscarf fabrics using four different with three fabric structures achieve comfortable scarf. micropolyester, TENCEL™, COOLMAX®, bamboo were selected construct 1/1 plain,...

Dental ceramics is a highly esthetic material and its surface properties can impact roughness, bonding properties, as well strength wear. The aim of the study to analyze characteristics by determination roughness parameters three dental used in computer-aided design/computer-aided manufacturing (CAD/CAM) technique: lithium disilicate (LS2), zirconium oxide-reinforced silicate (ZLS), oxide (ZrO2...

The color of 7 composite resins, an unfilled restorative resin, and 3 glaze coatings was determined by reflection spectrophotometry and visually with Munsell color tabs. Statistically significant correlations existed between comparable parameters of the spectrophotometric and Munsell data. There was observable color variations among the 11 resins studied, but only 3 materials were within the ra...

Over the last de ade, a dramati in rease has been observed in the ability to generate and store data in the ourse of parameter studies, performan e analysis, and software testing. In this paper, we introdu e ZENTURIO, a sophisti ated experiment management environment that greatly alleviates parameter studies, performan e analysis, and software testing for a wide variety of target ar hite tures,...
