摘要:
WASP and N-WASP proteins are provided that can be expressed in soluble form, including fusion proteins that contain full-length WASP and N-WASP. The proteins retain at least partial activity of full length WASP or N-WASP and some of the proteins fully recapitulate the activity of full-length WASP and N-WASP. Methods for expressing full-length WASP and N-WASP are also provided.

摘要:
Article of manufacture fabricated by plastic deformation of an intermetallic compound comprising R and M, such as an RM intermetallic compound and a higher order compound thereof, having a CsCl-type ordered crystal structure wherein R is one or more rare earth elements and M is one or more non-rare earth metals. The article of manufacture has a tensile elongation of at least about 5% prior to fracture when tensile tested at room temperature in ambient air. The article of manufacture also can be fabricated by plastic deformation of an intermetallic compound comprising a M′M compound and a higher order compound thereof having a CsCl-type ordered crystal structure wherein M′ and M are one or more different non-rare earth metals.
摘要:
Performance and reliability of microelectromechanical system (MEMS) components enhanced dramatically through the incorporation of protective thin film coatings. Current-generation MEMS devices prepared by the LIGA technique employ transition metals such as Ni, Cu, Fe, or alloys thereof, and hence lack stability in oxidizing, corrosive, and/or high temperature environments. Fabrication of a superhard, self-lubricating coating based on a ternary boride compound AlMgB14 is described in this letter as a potential breakthrough in protective coating technology for LIGA microdevices. Nanoindentation tests show that hardness of AlMgB14 films prepared by pulsed laser deposition ranges from 45 GPa to 51 GPa, when deposited at room temperature and 573 K, respectively. Extremely low friction coefficients of 0.04-0.05, which are thought to result from a self-lubricating effect, have also been confirmed by nanoscratch tests on the AlMgB14 films. Transmission electron microscopy studies show that the as-deposited films are amorphous, regardless of substrate temperature; however, analysis of FTIR spectra suggests that the higher substrate temperature facilitates formation of the B12 icosahedral framework, therefore leading to the higher hardness.

This invention relates to a ductile binder phase for use with AlMgB14 and other hard materials. The ductile binder phase, a cobalt-manganese alloy, is used in appropriate quantities to tailor good hardness and reasonable fracture toughness for hard materials so they can be used suitably in industrial machining and grinding applications.
