The discovery challenges basic assumptions about how metals solidify In A Nutshell Liquid metal contains stationary atoms: ...

Carbon nanotube field emitters are at present the brightest available electron sources but must operate at low currents to avoid Coulomb expansion and are therefore not suitable for ultrafast imaging.

Water (H₂O): Oxygen shares one electron with each of the two hydrogen atoms. Each hydrogen atom contributes one electron, resulting in oxygen having a total of 8 electrons in its valence shell (2 from ...

Scientists have calculated how it is possible to look inside the atom to image individual electron orbitals. An electron microscope can't just snap a photo like a mobile phone camera can. The ability ...

Therefore, the complete ground state electron configuration of carbon can be represented as 1s² 2s² 2px¹ 2py¹ 2pz⁰. It's ...

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 ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom’s central core and contains more than 99.9 ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

For millennia, atoms had been phantoms, widely suspected to exist but remaining stubbornly invisible — though not indivisible, as their name (Greek for “uncuttable”) originally implied. By the start ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

It’s like catching light in action. For the first time, physicists have measured changes in an atom to the level of zeptoseconds, or trillionths of a billionth of a second – the smallest division of ...

Ultrafast electron diffraction enables the study of molecular structural dynamics with atomic resolution at subpicosecond timescales, with applications in solid-state physics and rational drug design.
