Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

Hydrogen fuel cell vehicles bring together the power of combustion and the efficiency of electric propulsion while addressing the limitations of both. Ahh, hydrogen—the simplest and most ...

Alluxa introduces two Hydrogen Alpha (H-Alpha) Emission Line Filters that are revolutionizing the ultra-narrow optical filters market. Though these new filters have been specifically tailored to ...

The emission of radiation can be analysed by an ‘emission spectrum’. The different coloured lines show the frequencies emitted by electrons in atoms.

Hydrogen, known for its high energy output and zero-emission properties, has often encountered hurdles related to its low density and explosive characteristics, making storage and transport ...

One company is taking advantage of the unique structure of the aviation industry to carve out a new niche in zero-carbon propulsion with its hydrogen fuel cell powertrain. “We do powertrains ...
