Reactivity of Hydrogen-Helium and Hydrogen-Nitrogen Mixtures At High Pressures

Through a series of Raman spectroscopy studies, we investigate the behaviour of hydrogen-helium and hydrogen-nitrogen mixtures at high pressure across a wide range of concentrations. We find that there is no evidence of chemical association or increased miscibility of hydrogen … Continue reading

How Long Does The Photoelectric Effect Take?

In a flash: artist’s impression of the photoelectric effect. (Courtesy: Technical University of Vienna) Just 45 quintillionth of a second (45 attoseconds) is all it takes for a photon to liberate an electron from the surface of a metal. That … Continue reading
