METHOD FOR THE REDUCTION OF GRAPHENE FILM THICKNESS AND THE REMOVAL AND TRANSFER OF EPITAXIAL GRAPHENE FILMS FROM SiC SUBSTRATES

A method for reducing graphene film thickness on a donor substrate and transferring graphene films from a donor substrate to a handle substrate includes applying a bonding material to the graphene on the donor substrate, releasing the bonding material from the donor substrate thereby leaving graphene on the bonding material, applying the bonding material with graphene onto the handle substrate, and releasing the bonding material from the handle substrate thereby leaving the graphene on the handle substrate. The donor substrate may comprise SiC, metal foil or other graphene growth substrate, and the handle substrate may comprise a semiconductor or insulator crystal, semiconductor device, epitaxial layer, flexible substrate, metal film, or organic device.

Source-collector modules for EUV lithography employing a GIC mirror and a LPP source

Source-collector modules for use with EUV lithography systems are disclosed, wherein the source-collector modules employ a laser-produced plasma EUV radiation source and a grazing-incidence collector. The EUV radiation source is generated by first forming an under-dense plasma, and then irradiating the under-dense plasma with infrared radiation of sufficient intensity to create a final EUV-emitting plasma. The grazing incidence collector can include a grating configured to prevent infrared radiation from reaching the intermediate focus. Use of debris mitigation devices preserves the longevity of operation of the source-collector modules.

Electronically controlled prosthetic knee

InactiveUSRE42903E1Negligible changeNegligible pressureSpringsNon-rotating vibration suppressionMagnetorheological fluidControl theory
The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee which utilizes a plurality of interspersed and alternating rotors and stators to shear magnetorheological fluid in gaps formed therebetween. Advantageously, by operating in the “shear mode” there is substantially no or negligible fluid pressure buildup or change. Moreover, the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed—eliminating the need for a transmission—and also for a wide dynamic torque range. One embodiment of the invention allows the rotors and / or stators to close the gaps therebetween to create a frictional torque component, thereby forming a “hybridbraking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.

Non-fibrous high modulus ultra high molecular weight polyethylene tape for ballistic applications

A non-fibrous ultra high molecular weight polyethylene tape having a width of 1-inch or greater and a modulus of 1,400 grams per denier or greater. The non-fibrous UHMWPE tape is obtained by compression molding ultrahigh molecular weight polyethylene powder at a temperature below its melting point and then drawing and stretching the entire resultant compression molded UHMWPE sheet, with no slitting or splitting of the sheet, at a draw ratio of at least 100:1. The UHMWPE tape can be produced in weights of 6,000 to 90,000 denier or greater. The UHMWPE tape of the present invention minimizes the effect of stress concentrators that are prevalent with fibers and thereby enables the tape to be drawn at much higher draw ratios than is possible with fibrous UHMWPE. When used in ballistics panels, the high modulus high molecular weight polyethylene tape of the present invention improves ballistic performance by providing enhanced dissipation of the impact energy of a projectile.

Featured is a method and system for cleaning abrasive sanding and / or planing media, for example sandpaper, wide belt sanding belts, planers, grinding wheels or other abrasive surfaces while the media is either in-situ in the sanding, planing, grinding equipment or when removed. Additionally, the cleaning featured method and system can clean the media while the abrasive media is being used as well as when the abrasive media is not being used. In the cleaning method dry ice (CO.sub.2, solid carbon dioxide) particles are propelled towards the abrasive surface at a high velocity so the dry ice particles impact on the surface of the abrasive media at a high velocity. Additionally, the dry ice (CO.sub.2, solid carbon dioxide) particles are propelled as to impact the abrasive surface at varying angles and locations as necessary to effectively clean the abrasive surface. Further, the dry ice particles are propelled towards the abrasive media when it is in motion, for example rotating, so the dry ice particles impact the abrasive media at different locations of the media. The method and system allow the abrasive media to be cleaned while the abrasive media is being used for its' intended purpose. Thereby reducing equipment downtime usually associated with cleaning and / or changing the abrasive media due to becoming dirty and / or worn.
