Abstract: Methods and systems for X-ray imaging enable inspection of an area of an object that is located separate and apart from a location of an X-ray generator. An X-ray imaging system includes an X-ray generator to generate X-rays. A collimator filters the generated X-rays to consolidate the generated X-rays and move the generated X-rays in a direction parallel to a centerline axis of the collimator. A small diameter tube transmits the directed X-rays and an end retainer emits the transmitted X-rays at an inspection object. A first filter of the collimator may initially filter the generated X-rays that are not parallel to the centerline axis of the collimator by passing the X-rays through a plurality of apertures. A second filter of the collimator may consolidate the generated X-rays and move the generated X-rays in a direction parallel to the centerline axis of the collimator by passing the generated X-rays through a channel.

Abstract: A high precision replication system creates a nearly atomic level replica. The basic building block of the replication system is a substrate with a smooth replication surface which is to be replicated, and a graded transition layer applied to the replication surface. The graded transition layer comprises a binding material that adheres strongly to the replication surface and a release material that adheres to the replication surface with substantially less force than does the binding material. The portion of the transition layer closest to the substrate comprises predominantly the binding material, and the portion of the transition layer farthest from the substrate comprises predominantly the release material. A separation layer is applied to the transition layer, followed by a coating. The coating provides a backing to the separation layer, acting as structural support to the separation layer.
