Abstract: Liquid metal alloy precursor compositions and their use as liquid metal alloy ion sources for ion implantation of non-traditional source elements generally include liquid metal alloy precursor compositions having a melting point less than a maximum operating temperature for the ion implantation system of about 550° C. The liquid metal alloy precursor composition generally provides homogenous or heterogenous liquid metal alloys having eutectic melting temperature less than about 550° C. The heterogenous liquid metal alloy compositions include a flux metal having a relatively low melting point and at least one additional metal that is at least partially soluble in the flux metal at a selected operating temperature of less than about 550° C. The liquid metal alloy precursor compositions are suitable for use in ion implantation systems configured for liquid metal ion sources (LMIS) or capillary drive sources. Also disclosed are processes for implanting liquid metal alloy ion source precursor compositions.

Abstract: An endodontic reamer and a method for manufacturing endodontic reamers and files, more specifically an endodontic reamer having a cylindrical shaft and a working portion extending forward from a removed end of the shaft. The working portion includes, typically, a pair of wedged shaped projecting sections that extend beyond the diameter of the shaft. Forward from the wedge shaped sections is a nose, typically non-cutting nose, that has a diameter of about equal to diameter of the shaft. There are typically two (2) wedge shaped sections projecting outward opposite one another. Applicant also provides a novel method for manufacturing an endodontic reamer, which consists of using a two piece mold and placing a wire blank between the mold, followed by forcing the mold together, under compression, against the wire blank, to deform the blank into the shape of the mold parts.
