White beam Laue transmission diffraction topography has been used to determine the curvature of a crystalline substrate, from which the stress in the overlaying coating is determined. A detailed analytical method has been developed which correlates the introduction of curvature to the substrate in two orthogonal directions with attendant changes in the dimensions of a given topographic reflecti...

In the present study, the inherent characteristic of carbon nanotubes to absorb/attenuate the energy of electromagnetic waves has been exploited. The results indicate that the incorporation of CNTs in the polyurethane matrix has significant effect on the microwave interaction properties. Fabrics are developed through coating process using formulations based on different concentrations of multi ...

The ITO (indium tin oxide) conductive glass-matrix CuS-GeO2-TiO2 composite coating was generated via EPD (electrophoretic deposition) and followed by a sintering treatment at 450°C for 40 minutes. Characterizations of the CuS-GeO2-TiO2 composite coating were taken by SEM (scanning electron microscope), XRD (X-ray diffraction), EDX (energy dispersive X-ray), UV-Vis DRS (ultraviolet-visible diffu...

In this study layer by layer (LBL) self-assembled coatings of hyaluronic acid (HA) and cationized gelatin (CG) were used to modify polyethylene terephthalate (PET) artificial ligament grafts. Changes in the surface properties were characterized by scanning electron microscopy, attenuated total reflection Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and contact ...

We present a general design strategy for a broadband thin-film beam splitter with matched group-delay dispersion. By taking the substrate dispersion into account in the coating design, any combination of input and output can show the same dispersion for transmission and reflection. As a specific implementation, an ultrabroadband 50:50 beam splitter from 600 to 1500 nm for femtosecond laser appl...

We have employed attenuated total reflection Fourier transforms infrared spectroscopy sATR-FTIRSd to monitor the profile evolution of patterned mesoporous, low-dielectric-constant SiO2 films in situ and in real time during plasma etching. A stack of patterned photoresist, anti-reflective coating, and mesoporous SiO2 is etched in an inductively coupled plasma reactor, using CHF3 and Ar. During e...

Abstract The damaging effects of illumination on artwork are well known. Art conservation requires protection from both vandalism and radiation damage. Glass is an appropriate material for these requirements but it partially transmits UV and IR radiation. An optical coating on glass that eliminates UV and IR radiation coming from natural or artificial illumination, is proposed. This coated glas...
