Abstract: Articles having coatings that are resistant to high temperature degradation are described, along with methods for making such articles. The article comprises a coating disposed on a substrate. The coating comprises a plurality of elongated surface-connected voids. The article further includes a protective agent disposed within at least some of the voids of the coating; the protective agent comprises a substance capable of chemically reacting with liquid nominal CMAS to form a solid crystalline product outside the crystallization field of said nominal CMAS. This solid crystalline product has a melting temperature greater than about 1200 degrees Celsius. The method generally includes disposing the protective agent noted above within the surface connected voids of the coating at an effective concentration to substantially prevent incursion of CMAS materials into the voids in which the protective agent is disposed.

Abstract: Coating systems suitable for use in fluorescent lamps, particularly as scattering agents within a UV-reflecting coating for the purpose of improving fluorescent lamp luminosity. Such a coating system is provided on a transparent or translucent substrate and includes a phosphor coating and a scattering agent that scatters UV rays. The scattering agent includes an inorganic powder present in a separate UV-reflecting layer adjacent the phosphor coating and/or dispersed in the phosphor coating so that the scattered UV rays are absorbed by the phosphor coating and cause the phosphor coating to emit visible light. The inorganic powder exhibits low or no absorption to UV rays having wavelengths of 185 nm and 254 nm and is not reactive with mercury.

Abstract: The present approach generally relates to systems and methods for implementing energy modulated tomographic imaging of nanoparticles. In certain embodiments, a first energy is used to activate probe particles labeling an anatomy or tissue of interest. The probe particles, once activated, emit photons at a different rate and/or spectrum in response to an underlying physiological event, such as action potentials propagating in the labeled anatomy or tissue. The emitted photons may then be detected and used to map or image the occurrence of the physiological event.
