An interbody spinal implant is formed of cortical bone adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies. An asymmetrical leading end on the implant is adapted to sit upon the peripheral areas, such as the apophyseal rim and the apophyseal rim area, of the vertebral end plate region of the vertebral bodies without protruding therefrom. The asymmetrical leading end allows for the safe use of an implant of maximum length for the implantation space into which it is installed. The implant can also include an asymmetric trailing end adapted to sit upon the more peripheral areas of the vertebral end plate region of the vertebral bodies.

A polymer comprising recurring units having a partial structure of formula (1) wherein R1 is a single bond or alkylene or fluoroalkylene, R2 and R3 are H or alkyl or fluoroalkyl, at least one of R2 and R3 contains at least one fluorine atom is used as a base resin to formulate a resist composition which has advantages including high transparency to radiation having a wavelength of up to 200 nm, substrate adhesion, developer affinity and dry etching resistance

A semiconductor-on-insulator structure and a method of forming the silicon-on-insulator structure including an integrated graphene layer are disclosed. In an embodiment, the method comprises processing a silicon material to form a buried oxide layer within the silicon material, a silicon substrate below the buried oxide, and a silicon-on-insulator layer on the buried oxide. A graphene layer is transferred onto the silicon-on-insulator layer. Source and drain regions are formed in the silicon-on-insulator layer, and a gate is formed above the graphene. In one embodiment, the processing includes growing a respective oxide layer on each of first and second silicon sections, and joining these silicon sections together via the oxide layers to form the silicon material. The processing, in an embodiment, further includes removing a portion of the first silicon section, leaving a residual silicon layer on the bonded oxide, and the graphene layer is positioned on this residual silicon layer.
