  • Bright future for energy devices

    A little sodium goes a long way. At least that's the case in carbon-based energy technology. Specifically, embedding sodium in carbon materials can tremendously improve electrodes. A research team led by Yun Hang Hu, the Charles and Carroll McArthur Professor of materials science and engineering at more

  • New material could advance superconductivity

    Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that have no resistance to the flow of electrons, which increases electricity tran more

  • The Puzzle of the Origin of Elements in the Universe

    The LUNA experiment at the INFN Gran Sasso National Laboratory in Italy has observed a rare nuclear reaction that occurs in giant red stars, a type of star in which our sun will also evolve. This is the first direct observation of sodium production in these stars, one of the nuclear reactions that i more

Alkali metal roulette – reacting sodium and potassium with acid

Students generally make three requests after seeing the reaction of alkali metals with water: ‘Put in a bigger piece!’, ‘Can we see what happens with caesium?’ and ‘What happens if you do it in acid?’. Safety prohibits the use of bigger pieces, while cost and practical considerations prohibit th ... more
