Discovery of gold nanocluster 'double' hints at other shape-changing particles


Chemically the same, graphite and diamonds are as physically distinct as two minerals can be, one opaque and soft, the other translucent and hard. What makes them unique is their differing arrangement of carbon atoms. Polymorphs, or materials with the same composition but different structures, ...

Revealing the nature of magnetic interactions in manganese oxide


For nearly 60 years, scientists have been trying to determine how manganese oxide (MnO) achieves its long-range magnetic order of alternating up and down electron spins. Now, a team of scientists has used their recently developed mathematical approach to study the short-range magnetic ...

Scientists guide gold nanoparticles to form 'diamond' superlattices


Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet ...


Beam-beam compensation scheme doubles proton-proton collision rates at RHIC


Accelerator physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have successfully implemented an innovative scheme for increasing proton collision rates at the Relativistic Heavy Ion Collider ( RHIC ). More proton collisions at this DOE Office of Science User ...


RHIC particle smashups find that shape matters


Peering into the seething soup of primordial matter created in particle collisions at the Relativistic Heavy Ion Collider - an "atom smasher" dedicated to nuclear physics research at the U.S. Department of Energy's Brookhaven National Laboratory-scientists have come to a new understanding of how ...


Supercomputing the strange difference between matter and antimatter


An international team of physicists including theorists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has published the first calculation of direct "CP" symmetry violation - how the behavior of subatomic particles (in this case, the decay of kaons) differs when matter ...


Quantum spin could create unstoppable, one-dimensional electron waves


In certain nanomaterials, electrons are able to race through custom-built roadways just one atom wide. To achieve excellent efficiency, these one-dimensional paths must be paved with absolute perfection--a single errant atom can stop racing electrons in their tracks or even launch it backwards. ...

Physicists measure force that makes antimatter stick together


Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force ...

Flipping molecular attachments amps up activity of CO2 catalyst


New research by chemists at the U.S. Department of Energy's Brookhaven National Laboratory and their collaborators offers clues that could help scientists design more effective catalysts for transforming CO2 to useful products. The study reveals how a simple rearrangement of molecular attachments ...


Best precision yet for neutrino measurements at Daya Bay


In the Daya Bay region of China a research project is underway to study neutrinos. The international Daya Bay Collaboration announced new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment continues ...
