Immediately after the Big Bang, before the first stars in the Universe ever formed, the Universe consisted of hydrogen (element #1), helium (element #2) and pretty much nothing else. Despite ...
Structure, shape and composition are the basic parameters responsible for properties of nanoscale materials, distinguishing them from their bulk counterparts. To reveal these in three dimensions at ...
In the divertor and near-wall region of magnetic confinement fusion plasma experiments processes involving neutral atoms, molecules and molecular ions are important. The primary plasma constituents ...
Novel calculations have enabled the study of nearly 700 isotopes between helium and iron, showing which nuclei can exist and which cannot. Scientists report how they simulated for the first time using ...
New insight into the behaviour of atomic nuclei may explain how gigantic star explosions, or supernovas, have formed the elements that are crucial to humankind. Ground-breaking research in nuclear ...
How big is a helium atom? Or maybe the better question is: How small? After an intricate game of particle jockeying, physicists have now measured the radius of the helium nucleus five times more ...
First discovered in the corona surrounding the sun and later found in gases leaking from Mount Vesuvius, helium is the second-most abundant element in the universe. The second element on the Periodic ...
