How big is a proton? This doesn’t sound like a very complicated question, but it’s one that turned out to have the potential to wreck a lot of modern physics. That’s because different methods of ...

The proton is a positively charged particle that makes up every single atom in our Universe. We’re normally taught in schools that protons are really, really, really, REALLY, tiny dots of charge. But ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. How do atoms form? – Joshua, age 7, Shoreview, ...

Using the first new method in half a century for measuring the size of the proton via electron scattering, scientists have produced a new value for the proton's radius in a new experiment. Using the ...

Chemists reveal method for differentiating PCET mechanisms – a key step for steering fundamental energy conversion and redox catalysis processes. Redox reactions form the basis of many fundamental ...

Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

Proton-coupled electron transfer (PCET) reactions play a vital role in a wide range of chemical and biological processes. Recent advances in the theory of PCET will be presented. The quantum ...

A new measurement method suggests that the proton, a crucial subatomic particle in the Universe, is smaller than previously believed. All visible matter in the ...

The Chlamydomonas reinhardtii proton gradient regulation5 (Crpgr5) mutant shows phenotypic and functional traits similar to mutants in the Arabidopsis (Arabidopsis thaliana) ortholog, Atpgr5, ...
