Photonic crystals are nanoscopic structures designed to channel light of specific wavelengths while blocking other wavelengths. This ability to control and filter light with great efficiency makes ...
As inventors in the early 1900s vied to devise the best incandescent lightbulb, tungsten won out over carbon for making filaments. Today, however, there’s a form of carbon that was unknown back ...
You probably know that an incandescent light bulb uses a tungsten filament. What's even cooler is that it's got 20 inches of double-coiled filament -- and tungsten is a brittle mineral that, under ...
Over on YouTube [Drake] from the [styropyro] channel investigates what happens when you take an enormous tungsten incandescent light bulb and pump 30,000 watts through it. The answer: it burns bright ...
Tungsten-filament bulbs — the most widely used light source in the world — burn hands if unscrewed while lit. The bulbs are infamous for generating more heat than light. Now a microscopic tungsten ...
It may be that filament-based bulbs are on their way out, what with CFLs and LED bulbs taking over, but there’s still a lot to appreciate about the classic tungsten bulb. Apart from how reliable it’s ...
A microscopic 3-D tungsten photonic crystal lattice (TPCL) developed by Sandia National Laboratories (Albuquerque, NM) has demonstrated the potential to transmute the majority of wasted infrared ...
Canada’s biggest tungsten miner says it’s not worried about an Ontario government ban on incandescent light bulbs, to take effect by 2012. Stephen Leahy, CEO of Vancouver-based North American Tungsten ...
