Researchers from the Moscow Institute of Physics and Technology (MIPT) have for the first time experimentally demonstrated that copper nanophotonic components can operate successfully in photonic devices - it was previously believed that only gold and silver components have the required properties for this. Copper components are not only just as good as components based on noble metals, but, unlike them, they can easily be implemented in integrated circuits using industry-standard fabrication processes. "This is a kind of revolution - using copper will solve one of the main problems in nanophotonics," say the authors of the paper. The results have been published in the scientific journal Nano Letters.

NEMA’s Electroindustry Business Conditions Index (EBCI) for current conditions in North America fell back in February, dropping to 44.4 from 50 the previous month as more panelists reported conditions eroded than improved. Compared to January, smaller shares of the survey panel reported both that business conditions improved (22% in February compared to 41% in January) and that they deteriorated (33% in February compared to 41% in January). A plurality of panelists (44%) claimed conditions were unchanged in February. A considerably smaller 18% held this view a month ago.

In the fabrication of solid state lighting devices, scientists are learning, oxygen also plays a two-edged role. While oxygen can impede the effectiveness of gallium nitride (GaN), an enabling material for LEDs, small amounts of oxygen in some cases are needed to enhance the devices' optical properties. GaN doped with europium (Eu), which could provide the red color in LEDs and other displays, is one such case.

Researchers combine the warm look of traditional light bulbs with 21st-century energy efficiency. Traditional light bulbs, thought to be well on their way to oblivion, may receive a reprieve thanks to a technological breakthrough. Incandescent lighting and its warm, familiar glow is well over a century old yet survives virtually unchanged in homes around the world. That is changing fast, however, as regulations aimed at improving energy efficiency are phasing out the old bulbs in favor of more efficient compact fluorescent bulbs (CFLs) and newer light-emitting diode bulbs (LEDs).
