Abstract: A foundry sand comprises a blend that includes a silica sand and a zircon aggregate. The zircon aggregate exhibiting a sharp rise in linear thermal expansion coefficient in a temperature band above 1200° C. A method of casting an article in molten metal at a temperature above 1200° C. includes forming a single or multi-part mould for the article from the above-described foundry sand, admitting molten metal to the mould at a temperature such that at least one or more regions of the foundry sand in contact with the admitted metal are heated to a temperature within the temperature band, and cooling the mould and metal to obtain a cast article.

Abstract: In one aspect of the invention, an ion trap mass analyzer includes a variable- or multi-potential type ion guide (MPIG) assembly which has been pre-configured to produce a parabolic-type potential field. Each MPIG electrode has a resistive coating of designed characteristics. In one example the coating varies in thickness long the length of an underlying uniform substrate. The MPIG assembly can be a single MPIG electrode or an array of a plurality of MPIG electrodes. An array can facilitate delocalization for improved performance. This chemical modification of a uniform underlying substrate promotes cheaper and flexible instruments. The modified MPIG electrodes also allow miniaturization (e.g. micro and perhaps even nano-scale), which allows miniaturization of the instrument in which the single or plural modified MPIG electrode(s) are placed. This promotes portability and field use instead of limitation to laboratory settings.

Abstract: The present disclosure relates generally to a taggant system based on adsorbing at least two different metal elements in varying proportions into an inert encapsulating material, wherein the combination of metal elements and/or proportion of metal elements is an identifying marker of the taggant. The taggants can be uniquely identified by the metal elements it contains and/or the quantitation of their relative proportions. The taggants are stable, are quickly and easily identified, do not degrade or interact with the tagged material, can be designed to not degrade in extreme environments, and have a detection based on the emission of electromagnetic radiation that permits detection at trace levels.
