Abstract:
A hybrid electrochemical energy storage device having the attributes of a high power supercapacitor and a lithium ion battery are described. The hybrid electrochemical energy storage device can be a pseudocapacitor with a cathode having a coated activated carbon powder having a coated activated carbon cathode. The coated activated carbon can provide for enhanced energy density and ion conductivity. The activated carbon powder is coated with metal oxides, metal nitrides, metal sulfides, metal phosphates, polymers, and ion conducting or solid electrolytes, and a mixture thereof. More specifically, the activated carbon powder can include two or more active materials, with one of the two or more active materials being carbonaceous particles that comprise from about 50 to about 100 wt% of the composition, and the other of the two or more active materials atomic deposition layers on the carbonaceous particles. The atomic deposited layers can be metal oxides, metal nitrides, metal sulfides, metal phosphates, polymers, and ion conducting or solid electrolytes, and a mixture thereof.

Abstract:
The invention is directed to a system and method for detecting substances, such as explosives and/or drugs, using, in part, short bursts of energy light from a relatively low energy strobe. Embodiments include coupling the strobe with a detector for use in a 5 portable hand-held unit, or a unit capable of being carried as a backpack. Embodiments further include placement of one or more stroboscopic desorption units and detectors in luggage conveyors systems, carry-on X-ray machines, and check-in counter locations. Embodiments further comprise the use of a strobe or another energy source to assist in maintaining the integrity of a SERS substrate surface operatively associated with the 0 detector system, wherein the SERS substrate may be positioned in hand wand spaced apart from at least a portion of the detector. In another embodiment, the Raman excitation sourc may be located directly in the hand wand of a portable stroboscopic detection system.
