The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...

An animation shows how an infrared laser beam (orange) triggers atomic vibrations in a thin layer of iron selenide, which are then recorded by ultrafast X-ray laser pulses to create an ultrafast movie ...

For the first time, scientists have used ultrafast X-ray flashes to take a direct image of a single electron as it moved during a chemical reaction. In the new study, published Aug. 20 in the journal ...

Atomic-scale imaging emerged in the mid-1950s and has been advancing rapidly ever since—so much so, that back in 2008, physicists successfully used an electron microscope to image a single hydrogen ...

The lanthanide elements’ 4f electron orbitals are notoriously shy and retiring, and they were long thought to be unwilling partners in chemical bonding. Now chemists have brought out a surprising ...
