Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to ...

One of the joys of inorganic chemistry is exploring the periodic table to see what new and interesting things can be done with the elements. For Alexander Hinz of Oxford University and Axel Schulz and ...

A new model rectifies the long-standing deficiencies of the electronegativity concept.

Elements in group 18 (formerly group 0) of the periodic table are “inert” no more. Until recently, helium, the “noblest” of the noble gases, was the last one not to have been made into a compound with ...

The path that chemists typically follow to discover new materials is paved with decades of trial-and-error experiments. Guided by chemical intuition, researchers ...

Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food ...

Scripps Research chemist Matthew Disney, PhD, and colleagues have created drug-like compounds that, in human cell studies, bind and destroy the pandemic coronavirus' so-called "frameshifting element" ...
