The American physical society sees no technical reasons not to extend nuclear reactors to 80 years of operation and recommends doing so in a 28 page report. Renewing Licenses for the Nation’s Nuclear Power Plants Extending operating licenses for reactors in a safe and reliable way is a smart move, as they are a “near …
Nanoletters – Individual GaN Nanowires Exhibit Strong Piezoelectricity in 3D Semiconductor GaN NWs are promising components in next generation nano- and optoelectronic systems. In addition to their direct band gap, they exhibit piezoelectricity, which renders them particularly attractive in energy harvesting applications for self-powered devices. Nanowires are often considered as one-dimensional nanostructures; however, the electromechanical …
By fabricating an optical cavity around light-emitting nanotube mirrors at the bottom and top, wavelengths were confined to the desired 1.55-micron communications frequency. IBM researchers see a development path to light emitting nanotubes with no waste heat and a way to create a superlattice array of tubes for silicon photonic chips for optical computers. EETimes …
