20110021097 | Shape Memory Elastomeric Composites and Method of Manufacturing - A shape memory composite consisting of an electrospun non-woven fiber mat and an elastomeric resin matrix. The fiber mat is made from a semi-crystalline polymer, poly(ε-caprolactone) (PCL) and serves as the “switching phase” for shape fixing and recovery. The resin matrix, a crosslinked PDMS elastomer, imparts softness as well as entropic elasticity to the material. PCL is first electrospun from a chloroform/DMF solution. The resulting microfiber mat was then immersed in a two-part (base resin and crosslinking agent) mixture of Sylgard 184 with a vacuum applied to infiltrate the fiber mat with the mixture. The infiltrated fiber mat is then removed from the mixture and cured at room temperature for two days. | 01-27-2011 |

20140034955 | Nano-MOS Devices and Method of Making - The present invention discloses a method of making nano-MOS devices having a metal gate, thereby avoiding the poly depletion effect, and enhancing the MOS device's performance. The method forms metal gates by depositing a metal film over sidewall surfaces on two sides of a polycrystalline semiconductor layer. The metal in the metal film diffuses toward the sidewall surfaces of the polycrystalline semiconductor layer and forms, after annealing, metal-semiconductor compound nanowires (i.e., metal gates) on the sidewall surfaces of the polycrystalline semiconductor layer. Thus, high-resolution lithography is not required to form metal compound semiconductor nanowires, resulting in significant cost saving. At the same time, a nano-MOS device is also disclosed, which includes a metal gate, thereby avoiding the poly depletion effect, and resulting in enhanced MOS device performance. | 02-06-2014 |
