This invention provides a composite material for bipolar plates for fuel cells including cemented by a MPC binder and electrically conductive fillers, and a method of manufacturing the same. The resulting bipolar plate achieves low gas permeability, high electrical conductivity, high flexural strength and good corrosion resistance. The flexural strength and corrosion resistance can further be enhanced by the incorporation of macro-reinforcement and a polymer based surface treatment, respectively.

Si/SiO_(2) core/shell nanostructures with sizes below 30nm as trapping points in UV curable hybrid organic-inorganic gate dielectrics are presented in order to investigate printable nano floating gate transistors. Not only does the novelty of this invention comes from fabricating high-quality hybrid organic/inorganic gate dielectric layer by Sol-Gel process at low temperature but also incorporating the monolayer of high-density of Si nanoparticles (NPs) without obvious interface defects and keeping the quality of dielectric layers. Fixed-charge trapping defects are successfully removed from hybrid dielectrics by UV curing together with low temperature thermal curing and mobile charges solely related to Si/SiO_(2) core/shell nanostructures on charge trapping layer clearly demonstrate memory effects on printable device. Thin/uniform SiO_(2) shell on each Si NP functions as tunneling layer of flash memory devices, significantly simplifying the fabrication of printable nano floating gate memory device.

A tunable gain flattening filter includes a long-period grating device. The long-period grating device includes: an optical fiber that includes a core having a refractive index and a core guided mode with a first effective index, and a cladding surrounding the core and having a cladding mode with a second effective index that is less than the first effective index; a thermoelectric module, the optical fiber being mounted on the thermoelectric module; a thermoelectric cooler configured to precisely control temperature of the optical fiber; and a thermistor configured as a sensor to provide feedback for the thermoelectric module. A plurality of perturbations in refractive index are defined on the core spaced apart by a periodic distance so as to form a long-period grating with a center wavelength. Diameter of the optical fiber is tapered or etched by HF solution to about 6 to 10 m.
