Abstract: A method including forming a diamond material on the surface of a substrate; forming a first contact and a separate second contact; and patterning the diamond material to form a nanowire between the first contact and the second contact. An apparatus including a first contact and a separate second contact on a substrate; and a nanowire including a single crystalline or polycrystalline diamond material on the substrate and connected to each of the first contact and the second contact.

Abstract: A bridge and a method of constructing the bridge over water. A bridge span is positioned longitudinally in portion through a slot in a bridge pier; then the span is moved laterally through the slot to a position in the center of the pier at a low level. Then the span is hoisted up to its correct position. The hoisting step may be preceded by or may include placing jacks under the span and directly above the bottom of the pier and then employing the jacks in the hoisting step. The bridge or bridge segment comprises a pair of pier portions with a span-accepting slot between them, each pier portion comprising an underwater footing and a vertical pier portion resting on, secured to, and rising from the footing to a deck-support platform.

Abstract: A cable-stayed bridge. At least one vertical bridge tower supported by a pier is used in conjuction with a horizontal traffic-supporting deck having a cable girder beneath it and supporting it. A plurality of cable stays, are each anchored to the upper end of the tower and extend at an angle to and through the deck and are anchored to the cable girder. Each stay is prestressed and comprises an inner cable group of greased strands enclosed in an inner rigid structural pipe and an outer cable group of cemented grouted strands outside the inner pipe and enclosed by an outer rigid structural pipe. This outer rigid structural pipe surroundings the outer cable group and is separated therefrom by cement grouts. Each cable group has anchors for its extreme upper end and for its extreme lower end. Prestressing is done between the extreme ends to a desired tension.
