摘要： An enclosure for safe transportation and storage of a battery or a collection of batteries. The enclosure contains a plurality of batteries held together by a polymer structure, wherein the polymer structure contains s pockets capable of encapsulating at least one fire extinguishing fluid. Sensors deployed on a surface of each battery in the plurality of batteries are capable of monitoring surface temperature and volume expansion of each battery in the enclosure and providing signal output. The enclosure also contains a toxic gas release management and containment system.

摘要： An optical sensor system, comprising refractory plasmonic elements that can withstand temperatures exceeding 2500° C. in chemically aggressive and harsh environments that impose stress, strain and vibrations. A plasmonic metamaterial or metasurface, engineered to have a specific spectral and angular response, exhibits optical reflection characteristics that are altered by varying physical environmental conditions including but not limited to temperature, surface chemistry or elastic stress, strain and other types of mechanical load. The metamaterial or metasurface comprises a set of ultra-thin structured layers with a total thickness of less than tens of microns that can be deployed onto surfaces of devices operating in harsh environmental conditions. The top interface of the metamaterial or metasurface is illuminated with a light source, either through free space or via an optical fiber, and the reflected signal is detected employing remote detectors.

摘要： A magneto-plasmonic nanostructure is disclosed. The structure includes a substrate, and a magneto-plasmonic stack, comprising a nano-sized plasmonic resonator, a nanomagnet, and a capping layer, wherein the nano-sized plasmonic resonator is configured to receive circularly polarized light at an intensity to thereby increase normal component of plasmon-generated opto-magnetic field, HOM,z, at least at the interface of one of i) the nano-sized plasmonic resonator and the nanomagnet, or ii) the nanomagnet and the capping layer, whereby the HOM,z direction is perpendicular to the rotational direction of the circularly polarized light and the nanomagnets in the magneto-plasmonic stack switches its magnetic moment in response to a change of the HOM,z direction in response to a change of the rotational direction of the circularly polarized light.
