Scientists achieve higher precision weak force measurement between protons, neutrons

The n-helium-3 precision experiment, conducted at ORNL, measured the weak force between protons and neutrons by detecting the tiny electrical signal produced when a neutron and a helium-3 nucleus combine and then decay as they ....

New research shows the limitations of coordination in chemistry

Hydrogen in its plasma state. Credit: Alchemist-hp A common assumption in chemistry is that the coordination number of a catalyst's surface determines the reactivity of the reaction it catalyzes. Strikingly, chemists from Leiden University have ....
