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.

Abstract: An article including a substrate and a plurality of coatings disposed on the substrate is presented. The plurality of coatings includes a thermal barrier coating disposed on the substrate; and a protective coating including a calcium-magnesium-aluminum-silicon-oxide (CMAS)-reactive material disposed on the thermal barrier coating. The CMAS-reactive material has an orthorhombic weberite crystal structure. The CMAS-reactive material is present in the plurality of coatings in an effective amount to react with a CMAS composition at an operating temperature of the thermal barrier coating, thereby forming a reaction product having one or both of melting temperature and viscosity greater than that of the CMAS composition. A method of making the article and a related turbine engine component are also presented.

Abstract: Processes for producing particles of rare earth-containing phosphor materials, in which the particles have a core-shell structure and the shell has a lower rare earth content than the core. Such a process may include contacting a core particle with a precursor comprising Na(La,Ce,Tb)P2O7 to form a mixture, and then heating the mixture to a temperature sufficient to decompose the Na(La,Ce,Tb)P2O7 to evolve and melt an NaPO3 flux and initiate deposition of a (La,Ce,Tb)PO4 shell on each core particle in the presence of the molten NaPO3 flux.
