WebOct 1, 2024 · Two exciting research fields in modern optics are the fields of plasmonics and the optics of materials with vanishing permittivity, also known as epsilon-near-zero (ENZ) materials. On the one hand, plasmonics allows us to confine light at deep sub-wavelength scales, enabling the possibility of light-matter interactions over nanoscale dimensions. WebFuelPositive Corporation (Formerly EEStor) is a company based in Cedar Park, Texas, United States that claims to have developed a solid state polymer capacitor for electricity storage. The company claims the device stores more energy than lithium-ion batteries at a lower cost than lead-acid batteries used in gasoline-powered cars. Such a device would revolutionize …
