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 ...

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 ...

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 ...

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 ...

Lattices of microscopic tungsten rods can act as heat shields, researchers have found. Such structures may dramatically boost the efficiency of incandescent light bulbs and of thermophotovoltaic ...

This month, let’s take a deeper look at one of the most ubiquitous forms of illumination in our world: tungsten or incandescent bulbs. Incandescent means light from heat, which also includes the light ...

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 ...

I’m afraid to say this might be your last warning. If you’re relying on any tungsten light bulb other than the high power led ones, used in the Source Four, you are running on borrowed time. You’ve ...

Tungsten oxide nanocrystals engineered with oxygen vacancies absorb near-infrared light and enhance photocatalytic breakdown of dye pollutants in water. (Nanowerk Spotlight) Extending the ...

Scientists used beamlines at the Canadian Light Source (CLS) research facility to identify whether tungsten exposure raises health concerns. A McGill University research group said it has identified ...
