In the world of catalytic reactions, polymers created through electropolymerization are attracting renewed attention. A group of Chinese researchers recently provided the first detailed characterization of the electrochemical properties of polyaniline and polyaspartic acid (PASP) thin films. In AIP Advances, the team used a wide range of tests to characterize the polymers, especially their capacity for catalyzing the oxidation of popularly used materials, hydroquinone and catechol.

A new study carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility has confirmed that increasing the number of neutrons as compared to protons in the atom’s nucleus also increases the average momentum of its protons. The nuclear physics result, which has implications for the dynamics of neutron stars, has been published in the journal Nature.

In nature, the nuclear reactions that form stars are often accompanied by astronomically high amounts of energy, a challenge for nuclear astrophysicists trying to study these reactions; the chances of re-creating such a spark are unfathomably low. However, after recent renovations to its accelerator, one laboratory reported record-breaking performance. Following six years of upgrades to the Electron Cyclotron Resonance Ion Source at the Laboratory for Experimental Nuclear Astrophysics, researchers report improved results, discussed in Review of Scientific Instruments.
