Abstract: The disclosure discloses a testing device and a testing system for testing high-pressure and large-scale gap dynamic sealing performance of a plunger sleeve. The testing device includes two cylinders, first and second plunger rods and a piston rod. A first chamber is formed between an end of the first plunger rod and a first cylinder, and a second chamber is formed between an end of the second plunger rod and a second cylinder. The first chamber and the second chamber are provided with high-pressure liquid, and the two chambers communicate with each other. When being driven by a driving device, the piston rod drives the first and second plunger rods to reciprocate left and right. The plunger sleeve and a locking plunger sleeve are disposed outside each of the first and second plunger rods. The locking plunger sleeve has a leakage port. When the first and second plunger rods reciprocate, the high-pressure liquid in the chambers leaks from the leakage port.

Abstract: A molded nanoparticle phosphor for light emitting applications is fabricated by converting a suspension of nanoparticles in a matrix material precursor into a molded nanoparticle phosphor. The matrix material can be any material in which the nanoparticles are dispersible and which is moldable. The molded nanoparticle phosphor can be formed from the matrix material precursor/nanoparticle suspension using any molding technique, such as polymerization molding, contact molding, extrusion molding, injection molding, for example. Once molded, the molded nanoparticle phosphor can be coated with a gas barrier material, for example, a polymer, metal oxide, metal nitride or a glass. The barrier-coated molded nanoparticle phosphor can be utilized in a light-emitting device, such as an LED. For example, the phosphor can be incorporated into the packaging of a standard solid state LED and used to down-convert a portion of the emission of the solid state LED emitter.

Abstract: The surfaces of nanoparticles (QDs) are modified with amphiphilic macromolecules, for example, amphiphilic copolymers. The surface modification renders the QDs more compatible with oxygen-excluding matrices, such as epoxy resin, polyurethane resin, polyester resins or any hydrophilic inorganic/organic hybrid resin such as (meth)acrylate-functionalized polyhedral oligomeric silsesquioxane (POSS).
