Abstract: A thermally conductive adhesive comprises a mixture of at least two types of silver particles including a second type having a surface area to mass ratio in the range of 0.59 m2/g to 2.19 m2/g and a tap density in the range of 3.2 to 6.9 g/cm3 and a first type having a surface area to mass ratio of 0.05 to 0.15 m2/g and a tap density in the range of about 4.7 to 8.2 g/cm3. According to certain embodiments of the invention the first type of silver particles includes oblong silver particles. The thermally conductive adhesive further comprises a binder, and optionally a solvent.

Abstract: Conductive compositions which are useful as thermally conductive compositions and may also be useful as electrically conductive compositions are provided. The compositions include a conductive particle constituent in combination with a sintering aid which can, for example be a compound of the same metal in the nanometal, an organo-metallic, a metalorganic salt, mercaptan and/or resinate. In some embodiments the conductive particles include a small amount of nanoscale (<200 nm) particles. The compositions exhibit increased thermal conductivity.

Abstract: A fiber optic feed-through tube, a method for making it and a method for hermetically sealing and aligning lightwave waveguides inserted into the tube. The feed-through tube is preferably a metal tube with low melting point hermetic sealing material deposited on one end and the lightwave waveguide is an optical glass fiber. The fiber is fed through a tube having low melting point hermetic sealing material on one end.
