Researchers have developed lignin-based jet fuel to store hydrogen in a stable liquid form, revolutionizing sustainable ...

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 ...
