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

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 ...

ON June 1 the annual Halley lecture at the University of Oxford was delivered by Prof. Henry Norris Russell, professor of astronomy and director of the University Observatory, Princeton, on the ...

In the decade since their discovery at Drexel University, the family of two-dimensional materials called MXenes has shown a great deal of promise for applications ranging from water desalination and ...

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 ...

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 ...

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 ...

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

As astronomers gaze into the depths of space, they do so with unease: They don’t know precisely what the universe is made of. It’s not just the true nature of dark matter that eludes them; so does the ...
