When the Nobel Prize-winning US physicist Robert Hofstadter and his team fired highly energetic electrons at a small vial of hydrogen at the Stanford Linear Accelerator Center in 1956, they opened the ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

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

For the first time, researchers have reported a 3D metal-organic framework (MOF) that can conduct both electrons and protons (J. Am. Chem. Soc. 2024, DOI: 10.1021/jacs.4c13792). Materials mixing ...

Advanced mathematical analysis of the ionisation of a helium atom by an impacting proton has revealed where discrepancies arise between experiments and existing theoretical calculations of the process ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

The most precise measurement to date of the proton-electron mass ratio suggests that the proton may be lighter than previously thought. The result, from researchers in the Netherlands and France, ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed and tested the world's highest voltage polarized electron gun, a key piece of technology needed for ...

Imines are one of several reactive groups, called functional groups, that are present in a compound. The mechanism by which the compound reacts is attributed to the properties of its functional group.

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.

In a new study published in EPJ D, researchers have clearly identified particular areas where discrepancies arise between theoretical and experimental measurements of helium ionization by an impacting ...
