The positions of all the atoms in a sample of a metallic glass have been measured experimentally — fulfilling a decades-old dream for glass scientists, and raising the prospect of fresh insight into ...

For more than a decade, physicists have faced a puzzling situation: the size of the proton, the nucleus of the hydrogen atom, ...

Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms, ...

Many substances around us, from table salt and sugar to most metals, are arranged into crystals. Because their molecules are laid out in an orderly, repetitive pattern, much is understood about their ...

Researchers at the Kastler Brossel Laboratory in Paris have made the most precise measurement of one of the fundamental constants, called the fine-structure constant, providing physicists with a vital ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...

Until now, it was generally believed that gold simply does not react with oxygen and therefore does not discolor. On May 21, ...
