A die attach paste composition comprising (a) an organosilicone resin; (b) a single crystal alumina filler; (c) a hardener; and (d) an inhibitor. By using single crystal alumina filler in a silicone based die attach paste, thermal conductivity and anti-yellowing properties are improved in comparison with other spherical alumina particles at the same filler loading content.

A composite material comprises a polymer matrix having microstructure filler materials that comprise a plurality of interconnected units wherein the units are formed of connected tubes. The tubes may be formed by photo-initiating the polymerization of a monomer in a pattern of interconnected units to form a polymer microlattice, removing unpolymerized monomer, coating the polymer microlattice with a metal, removing the polymer microlattice to leave a metal microlattice, growing or depositing a material on the metal microlattice such as graphene, hexagonal boron nitride or other ceramic, and subsequently removing the metal microlattice.

According to examples, an article may include a base layer that extends along a first dimension and a second dimension, in which the second dimension is orthogonal to the first dimension. The article may also include reflective ribbons provided on an upper surface of the base layer, in which the reflective ribbons positioned along a common plane extending in the second dimension have dihedral angles that change as a function of distance across the common plane.

A polyester resin composition for a vibration-damping material, containing a thermoplastic polyester resin constituted of a dicarboxylic acid component and a diol component (A), one or more members selected from the group consisting of plasticizers and styrene-isoprene block copolymers (B), and an inorganic filler (C). The polyester resin composition of the present invention can be suitably used as a vibration-damping material for a material for audio equipment such as, for example, speakers, television, radio cassette players, headphones, audio components, or microphones, and manufactured articles such as electric appliances, transportation vehicles, construction buildings, and industrial equipment, or parts or housing thereof.

The subject of the application relates generally to the field of drainage elements, typically drainage channels, and covers thereof, as well as mixtures for production of such covers. Embodiments may include drainage element covers, meeting functional (water permeability, slip resistance, abrasion resistance, hygienic safety, strength, resistance to frost, etc.) as well as aesthetic requirements, and which would be suitable for applications in exteriors as well as interiors, and further propose a mixture for production of such drainage element covers. Functional and aesthetic requirements may be achieved by means of a mixture for producing drainage element covers, comprising aggregate and/or milled glass pulp and binder, and further comprising thixotropic additive.

An organic-inorganic composite including: a plurality of anisotropic ceramic particles having different aspect ratios; a resin that is combined with the ceramic particles; and a plurality of projections projecting out from the surface of the ceramic particles, thereby increasing the shear resistance of the interface between the ceramic particles and the resin. At least some of the ceramic particles neighboring each other are closely arranged such that the projections partially contact each other, thereby increasing the shear resistance between the ceramic particles due to the contacting ceramic particles.

A flame retardant block copolymer is prepared from renewable content. In an exemplary synthetic method, a bio-derived flame retardant block copolymer is prepared by a ring opening polymerization of a biobased cyclic ester and a phosphorus-containing polymer. In some embodiments, the biobased cyclic ester is lactide. In some embodiments, the phosphorus-containing polymer is a hydroxyl-telechelic flame retardant biopolymer prepared by a polycondensation reaction of a biobased diol (e.g., isosorbide) and a phosphorus-containing monomer (e.g., phenylphosphonic dichloride). In other embodiments, the phosphorus-containing polymer is synthesized from a dioxaphospholane monomer.
