An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...

Learn about how Mark Raizen and his team at UT Austin have developed the world's highest resolution atom lens. An atom lens is analogous to a glass lens used in an optical microscope or magnifying ...

Scientists have assembled single atoms of different elements, thus forming nanostructures of predefined size and composition. The nanostructures engineered and characterized constitute a promising ...

All the elements in the Periodic Table are made from different atoms, and the structure of these atoms results in a gamut of phenomena from radioactive decay to nuclear power. When you purchase ...

The precise chemical composition of the Sun, particularly the abundance of heavy elements like oxygen, carbon, nitrogen, and neon relative to hydrogen, remains a significant point of contention in ...

ISS involves the bombardment of a surface with a beam of ions, typically noble gas ions like helium or neon, under vacuum conditions. When these ions collide with the sample surface, they are either ...

Curious Kids is a series for children of all ages. If you have a question you'd like an expert to answer, send it to [email protected]. For the first time, physicists peer inside the ...

The precise measurement of an exotic atom in the laboratory has refined scientists’ understanding of neutron stars, which are among the universe’s most extreme objects. The study, published January 22 ...
