Green-chemistry researchers at McGill University have discovered a way to use water as a solvent in one of the reactions most widely used to synthesize chemical products and pharmaceuticals. The findings mark a potential milestone in efforts to develop organic reactions in water. Chao-Jun Li and ...

Grandaddy Purple, Blueberry Yum Yum and other pot products may now be legal for medical use in 20 states and the District of Columbia, but how do patients know what dose they’re really getting and whether it’s safe? Small labs are setting up shop — some at their own legal peril — to help patients ...
Using “dark channel” fluorescence, scientists can explain how biochemical substances carry out their function

Spectroscopic techniques are among the most important methods by which scientists can look inside materials. They exploit the interaction of light waves with a given sample. Now, using X-ray absorption spectroscopy, researchers from Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) have ...
