Researchers develop a reactor that can destroy 'forever chemicals'

"Forever chemicals," named for their ability to persist in water and soil, are a class of molecules that are ever-present in our daily lives, including food packaging and household cleaning products. Because these chemicals ...

Super-dense packing of hydrogen molecules on a surface

Hydrogen (H2) is currently discussed as an ideal energy carrier of renewable energies. Hydrogen has the highest gravimetric energy density of all chemical fuels (141 MJ/kg), which is three times higher than gasoline (46 MJ/kg). ...

World's first 'green' synthesis of plastics from CO2

By combining a CeO2 catalyst with atmospheric carbon dioxide, researchers from Osaka City University, Tohoku University, and Nippon Steel Corporation have developed an effective catalytic process for the direct synthesis ...

A chiral surprise in the rainforest

Forests such as the Amazon rainforest emit huge amounts of biogenic volatile organic compounds (BVOC) into the atmosphere. These compounds impact the physical and chemical properties of the atmosphere and also our climate. ...

Demonstrating the Mpemba effect in a controlled setting

A pair of physicists at Simon Fraser University has developed a means for demonstrating the Mpemba effect in a controlled setting. In their paper published in the journal Nature, Avinash Kumar and John Bechhoefer describe ...

Supercritical answer to waste oil found

Lubricating oils deteriorate and oxidize with use as well as accumulating particles from the engines and other machinery in which they are used. Ultimately, their effectiveness worsens and they begin to damage the components ...

Tungsten as interstellar radiation shielding?

A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions—especially in heat-loving microorganisms. A team led by Tetyana ...
