Abstract

A method and a system for identifying an explosive in a sample are disclosed. The method comprises receiving an explosive fingerprint defined by a set of kinetic parameters, describing a plurality of interactions between the explosive and each of a respective plurality of functional moieties. The method further comprises using a data processor for accessing a database of explosive fingerprints, and searching the database for a database fingerprint matching the received fingerprint. The system comprises a plurality of sensing devices, each comprising semiconductor nanostructures (e.g. Si nanowires) having attached thereto a functional moiety selected to interact with a nitro-containing and/or peroxide-containing explosive sample.

Abstract

A fuel cell system comprising an anode compartment which comprises an anode having a copper catalyst layer, a cathode configured as an air cathode and a separator interposed between said anode and said cathode, operable by an amine-derived fuel and oxygen (or air) is disclosed. Further disclosed are fuel cell systems comprising an anode compartment which comprises an anode having a copper catalyst layer, a cathode and a separator interposed between said anode and said cathode, which are operable by a mixture of two types of amine-derived compounds (e.g., ammonia borane, hydrazine and derivatives thereof). Also disclosed are methods of producing electric energy by, and electric-consuming devices containing and operable by, the disclosed fuel cell systems.
