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 ...

Scientists from Japan have developed a novel method for measuring hydrogen gas that employs tunable diode laser absorption spectroscopy (TDLAS) at different pressures and a high-pressure gas cell.

A biohybrid system combines polymer nanosheets with E. coli to improve hydrogen production by capturing near-infrared light ...
