MECHANOLUMINESCENCE POLYMER DOPED FABRICS AND METHODS OF MAKING
Described herein is the application of centrifugal spinning to provide a flexible mechanoluminescent material composed of rare earth metal doped fibers. Rare earth metal doped fibers are formed, in one embodiment, by centrifugal spinning.
Phosphor composition
A method is disclosed for forming a blended phosphor composition. The method includes the steps of firing precursor compositions that include europium and nitrides of at least calcium, strontium and aluminum, in a refractory metal crucible and in the presence of a gas that precludes the formation of nitride compositions between the nitride starting materials and the refractory metal that forms the crucible. The resulting compositions can include phosphors that convert frequencies in the blue portion of the visible spectrum into frequencies in the red portion of the visible spectrum.
NUCLEIC ACIDS ENCODING ANTIBODIES SPECIFICALLY BINDING TO MASP-3
The present invention relates to MASP-3 inhibitory antibodies and compositions comprising such antibodies for use in inhibiting the adverse effects of MASP-3 dependent complement activation.
CORE-SHELL NANOPHOSPHOR AND LIGHT SOURCES
Nanophosphors are provided comprising a nanoparticle core having an attached shell of smaller silicon nanoparticles attached via hydrogen bonding. Example methods for forming a nanophosphor comprise providing a silicon nanoparticle (SiNp) colloid including Si nanoparticles, and transferring the colloid to a solid state comprising silica and/or phosphor particles. Drying is allowed such that the Si nanoparticles form a coating on the particles with hydrogen bonds.
Light emitting device and light source
A light emitting device includes at least one first light emitting element to emit a first light and at least one fluorescent material to convert the first light to a second light. The second light has chromaticity existing in an enclosed area in a CIE 1931 chromaticity diagram. The CIE 1931 chromaticity diagram has a curved boundary indicating a spectral locus. The enclosed area is enclosed with a first straight line, a second straight line, a third straight line, and a curved line. The first straight line connects a first point at which x is equal to 0.666 and y is equal to 0.334 and a second point at which x is equal to 0.643 and y is equal to 0.334. The second straight line connects the second point and a third point at which x is equal to 0.576 and y is equal to 0.291. The third straight line connects the third point and a fourth point at which x is equal to 0.737 and y is equal to 0.263. The curved line connects the fourth point and the first point. The curved line is a part of the curved boundary.
