The team uses an electron microscope capable ... The UCLA research team's light bulb is very similar to Edison's, except that their filament is 100,000 times narrower and 10,000 times shorter ...

Filament bulbs and other commonly used light sources ... very old way to generate these photons—not relying on photon and electron excitations, but like the bulb Edison developed,” said ...

These are electron emitters ... This is not the only recent attack on the good old light bulb. In 2002 (EW 15/05/02) Sandia Labs in New Mexico made a filament from a tungsten photonic crystal. The ...

While thermionic electron sources such as the ... to boil electrons off the surface of a wire filament, similar to the way an incandescent light bulb uses an electric current to heat a wire ...

"It's hard to generate enough brightness when producing twisted light with traditional ways like electron or photon ... While ...

We detect a net surface brightness from our sample of filaments of (1.6±0.1)× 10^−14 erg cm^−2 s^−1 arcmin−2 in the 0.9–1.3 keV energy band for 1 keV plasma, which implies an electron density. Finally ...

The problem with older light bulbs, which have not changed in their basic design since the days of Thomas Edison more than a century ago, is that they generate light by heating a thin filament of ...

Yet, the newest addition to the Tradfri smart light family stands out for two reasons. First, it’s the company’s first smart filament light bulb, meaning it’s more decorative and glows a little warmer ...

An electron microscopy study revealed key details ... with growing "barbed" and shrinking "pointed" ends. The ends of the filament are also different in the way they interact with other proteins ...
