Flowable brazing compositions and methods of brazing metal articles together using the same are provided herein. In an embodiment, a flowable brazing composition includes a non-polymeric carrier medium and flux-coated particles. The carrier medium includes at least one polar organic solvent and is liquid at ambient temperature. The flux-coated particles include a braze material core and a flux coating disposed on the core. The braze material core includes different material from the flux coating. The flowable brazing composition has less than or equal to about 1.5 weight % of polymeric binder components, based upon a total weight of the flowable brazing composition.

A method for reducing pressure build-up in an electrochemical cell is provided comprising: providing an anhydrous nonaqueous electrolyte solution comprising at least one quaternary ammonium salt and at least one anhydrous nonaqueous solvent; contacting the electrolyte solution with at least one acid scavenger; and loading the nonaqueous electrolyte solution into the electrochemical cell. Also, provided is an electric double-layer capacitor (supercapacitor) comprising a free acid scavenger.

High voltage electrolytes

This invention provides security articles comprising fibers, threads and fiber sections ('dots') possessing multiple verification characteristics. The fibers possess unique and difficulty duplicated combinations of complex cross-sections, components, and multiple luminescent responses. The many verifiable characteristics of the security fibers, threads and dots provide high levels of protection against fraudulent duplication of articles in which they are incorporated. The manifold security features provide means of tailoring specific identity characteristics for specific use and users.
