Research has shown that protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, which allows a greater fraction of the protons than neutrons to have high momentum in relatively neutron-rich nuclei, such as carbon, aluminum, iron and lead. This result is contrary to long-accepted theories large nuclei and has implications for ultra-cold atomic gas systems and neutron stars.
Protons hog the momentum in neutron-rich nuclei

A team of researchers, including scientists from Jefferson and Argonne national laboratories, found that protons and neutrons that have briefly paired up in the nucleus have higher-average momentum, leaving less for non-paired nucleons - including in nuclei heavier than carbon.

Researchers fight friction and wear with one-atom-thick graphene

Nanoscientist Anirudha Sumant and his colleagues at Argonne’s Center for Nanoscale Materials and Argonne’s Energy Systems division applied a one-atom-thick layer of graphene, a two-dimensional form of carbon, in between a steel ball and a steel disk. They found that just the single layer of graphene lasted for more than 6,500 “wear cycles,” a dramatic improvement over conventional lubricants like graphite or molybdenum disulfide.

Techniques at Argonne’s Electron Microscopy Center helped scientists get a complete picture of this chemical reaction. Over the course of the reaction, the nanorod on the top left is slowly covered with a growth of copper deposits from the solution. Maps showed the locations of the elements in the reaction: Ag, or yellow, representing silver; blue representing gold, Au; and Cu, copper, shown in red.

Electron microscopes take first measurements of nanoscale chemistry in action

Scientists’ underwater cameras got a boost this summer from the Electron Microscopy Center at Argonne National Laboratory. Along with colleagues at the University of Manchester, researchers captured the world’s first real-time images and simultaneous chemical analysis of nanostructures while “underwater,” or in solution.

Mysteries of space dust revealed

The first analysis of space dust collected by a special collector onboard NASA’s Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks open a door to studying the origins of the solar system and possibly the origin of life itself. This is the first time synchrotron light sources have been used to look at microscopic particles caught in the path of a comet.
