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.

The combination of ab-initio numerical experiments and theory shows that optical tunneling of an electron from an atom can occur instantaneously. The combination of ab-initio numerical experiments and ...

Scientists have directly measured the minuscule electron sharing that makes precious-metal catalysts so effective. Their new technique, IET, reveals how molecules bind and react on metal surfaces with ...

Scientists precisely removed a gold nanocluster's core atom and outer electron, revealing how spin state affects catalytic activity without structural loss. (Nanowerk News) In a breakthrough that ...

Scientists have captured the first ever photo of an electron’s whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique. Seeing inside the tiniest bits of matter is a ...

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 ...

Since the body can naturally produce CoQ10 and you can consume it in your diet, why bother with a supplement? Here's what to ...

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 ...

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 ...

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.
