Abstract: A packaged semiconductor chip includes a semiconductor sub strate having formed thereon: radio-frequency (RF) input and output contact pads, DC contact pads, and first and second amplifier stages. An input of the first amplifier stage is coupled with the RF input contact pad. An input and an output of the second amplifier stage are respectively coupled to an output of the first amplifier stage and the RF output contact pad. The DC contact pads and the input of the first amplifier stages are connected via an input bias coupling path. The outputs of the amplifier stages are connected via an output bias coupling path. The chip further includes a lead frame having RF input and output pins electrically coupled to the RF input and output contact pads, and input bias pins electrically coupled to the DC contact pad.

Abstract: An electrode for a lithium-ion battery includes a substrate; and a composite deposited on the substrate, wherein the composite comprises layered graphene comprising mono-, bi- and n-layered graphene, wherein n is an integer selected from 3-about 6; and nanoparticles of a material selected from a cathode active material and an anode active material, wherein the surface of each of said nanoparticles is coupled to and conformally coated with said layered graphene, and wherein said layered graphene is not graphene oxide and is not reduced graphene oxide.

Abstract: Anhydrous liquid-phase exfoliation of germanium sulfide to provide few-layer germanium sulfide, as can be incorporated into electronic devices such as but not limited to batteries and cells comprising such materials.

Abstract: This invention provides a flame-retardant thermoplastic composition comprising a blend of ethylene copolymers, polyethylene, metal hydroxides and optionally a coupling agent and a compatibilizing agent, which is mildly cross-linked during blending with a peroxide and a polyfunctional compound. The composition has superior flame retardancy and a good balance of mechanical properties and electrical insulating properties, and maintains melt processibility for use as a sheath or insulation for wires and cables.

Abstract: Neoprene compositions containing a latex of a copolymer of chloroprene with an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, such as methacrylic or acrylic acid, the polymerization being conducted in the presence of polyvinyl alcohol, and zinc oxide or zinc hydroxide which has been previously contacted with an alkali metal hydroxide are particularly well suited for use in contact adhesives.
