Penning-trap system enables loss-free transfer of protons between experimental sites

Protons are the basic building blocks of matter. Together with neutrons, they form atomic nuclei. These minute, positively charged particles have an antimatter counterpart, antiprotons. While the latter have a negative charge ...

Optical tweezers reveal forward and backward motion is symmetric in molecular shuttling

In molecular shuttles, a ring molecule is threaded onto a linear molecular strand and can move between two portions of the strand, called stations, in response to external stimuli. Chemical stimuli, light or mechanical forces ...
