When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend and twist at characteristic rates that fall in the infrared region of ...

Whether a smartphone battery lasts longer or a new drug can be developed to treat incurable diseases depends on how stably ...

Scientists report the first confirmed detection of thiepine, a complex sulfur-bearing molecule, in an interstellar cloud near the Milky Way’s center.

Researchers from the Max Planck Institute for Extraterrestrial Physics in Germany and the Centro de Astrobiología, part of ...

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough ...

A collaborative effort from researchers at the Lawrence Livermore National Laboratory (LLNL), Sandia National ...

Imagine a knot so small that it can’t be seen with the naked eye. Then think even smaller. Chemists have tied together just 54 atoms to form the smallest molecular knot yet. Described January 2 in ...

Scientists have long dreamed of making molecular electronics, building one-dimensional strings atom by atom to create new circuits even smaller than today’s tiniest silicon structures. Shrinking ...

Probing the vibration of atoms provides detailed information on local structure and bonding that define material properties.
