Nanocomposite materials with dynamically adjusting refractive index and methods of making the same
A concept and synthesis technology for a composite nanoparticle material which can be used to develop nanocomposite films and suspension with 1) dynamic refractive index control across a wide temperature and wavelength of light, and specified refractive index range, or 2) magnetic susceptibility or electronic conductivity over a wide temperature, magnetic field and electric field range. Core-shell nanoparticles can be made from two or more materials whose temperature dependent, electric field dependent or magnetic field dependent properties compensate one another will dynamically maintain a targeted refractive index, electronic conductivity or magnetic susceptibility over a specified temperature, electric and/or magnetic field range.

Anti-reflective film for photovoltaic arrays
A film containing polymeric particles which have an average particle diameter from 0.75 to 15 μm and a refractive index which changes continuously from the center of the particles to the surface. The particles are embedded in a continuous polymeric phase comprising a polyolefin.

Oxygen carrying materials and methods for making the same
A method for producing an oxygen carrying material may include forming a mixture that includes powders of active mass precursor, support material precursor, and inert structure precursor, and producing the oxygen carrying material by heating the mixture at a temperature of greater than 1300° c. For a time sufficient to sinter the inert structure precursor to form a high-strength inert structure.
