More than a century after their invention, tungsten filaments—the coiled metal wires at the heart of many incandescent light bulbs—continue to be popular. This is despite the growing market for LED ...

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 ...

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 ...

Although tungsten-filament bulbs are the world’s most extensively used light source, they are inefficient and generate more heat than light. However, a new microscopic tungsten lattice created at the ...

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 ...

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 ...

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 ...
