Selected Properties of a Synthetic Quartz Glass-Ceramic
QDT 2005 1 he restoration of missing or compromised tooth structure requires dental materials that offer toothlike esthetics, functionality, biocompatibility, and longevity. Silica-based ceramics (eg, feldspathic porcelain) offer all of these necessities and are the materials of choice for esthetic all-ceramic restorations (eg, laminate veneers, ceramic inlays and onlays, and full-coverage jack...
متن کاملCapillary aging of the contacts between glass spheres and a quartz resonator surface.
The strength of the contacts between small glass spheres and the surface of a quartz crystal resonator has been probed based on the increase of resonance frequency induced upon sphere contact. The acoustic interaction between the sphere and the plate is modeled as a low-frequency coupled resonance; the dependence of the resonant parameters on overtone order lends support to this model. After ex...
متن کاملNanostructured Al-ZnO/CdSe/Cu2O ETA solar cells on Al-ZnO film/quartz glass templates
The quartz/Al-ZnO film/nanostructured Al-ZnO/CdSe/Cu2O extremely thin absorber solar cell has been successfully realized. The Al-doped ZnO one-dimensional nanostructures on quartz templates covered by a sputtering Al-doped ZnO film was used as the n-type electrode. A 19- to 35-nm-thin layer of CdSe absorber was deposited by radio frequency magnetron sputtering, coating the ZnO nanostructures. T...
متن کاملThe Luminescence of Air , Glass and Quartz under a - Particle Irradiation
The luminosity of a zlOPo source has been detected using a photomultiplier technique. It is also found that photons are produced in air, glass and quartz when these materials are irradiated by a-particles. It is shown that the ' scintillations ' observed by Richards and Cole probably originated in these materials, and not in the various thin films to which they were ascribed. T is well known th...
متن کاملVO2 Thermochromic Films on Quartz Glass Substrate Grown by RF-Plasma-Assisted Oxide Molecular Beam Epitaxy
Vanadium dioxide (VO₂) thermochromic thin films with various thicknesses were grown on quartz glass substrates by radio frequency (RF)-plasma assisted oxide molecular beam epitaxy (O-MBE). The crystal structure, morphology and chemical stoichiometry were investigated systemically by X-ray diffraction (XRD), atomic force microscopy (AFM), Raman spectroscopy and X-ray photoelectron spectroscopy (...
