  • Publication number: 20240117170
    Abstract: A composition for electroless plating comprises: from 9 to 29 weight percent, 9.7 to 29 weight percent, or 10 to 29 weight percent, of a first graft rubber copolymer which comprises the polymerized form of at least one conjugated diene monomer and at least one monovinyl aromatic monomer, from 70 to 90 weight percent, preferably 70-89.7 weight percent, more preferably 70 to 85 weight percent, of ungrafted styrenic polymer, from 0.1 to 10 weight percent of a core/shell diene-based rubber having particle size of 100 to 500 nanometers (nm), one or more of a stabilizer and/or antioxidant in total amount of from 0.1 to 5 weight percent, a fatty acid or a salt of fatty acid in an amount of from 0.1 to 2 weight percent, 0 to 5 weight percent of a mold release agent, 0 to 1 weight percent of a metal oxide, 0 to 3 weight percent of a lubricant, and 0 to 20 weight percent of polycarbonate wherein weight percent and ppm are based on total weight of the composition.

  • Publication number: 20150228826
    Abstract: A High Purity Germanium (HPGe) radiation detector has been specially machined to be this invented series multi-chamber coaxial configuration. So extra-large volume HPGe detectors can be easily produced with current available HPGe crystal, and the entire detector body structure can be uniquely optimized in accordance with the exact semiconductor crystal ingot situation so the overall detector can be easier depleted and the photo-induced carriers can be better collected as the signal output. This invention makes extra-large efficiency HPGe gamma ray detectors of 100% to 200%, and maybe even higher efficiency, possible and easier to be produced based on current HPGe crystal supply capability. The invention improves the detector performance for very high energy gamma ray detection especially. The invention could also be applied to any other kind of semiconductor materials if any of them could be purified enough for this application in future.
