    Beam-Beam Compensation Scheme Doubles Proton-Proton Collision Rates at RHIC

    Accelerator physicists at the U.S. Department of Energy's 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 Facility produce more data for scientists to sift through to answer important nuclear physics questions, including the search for the source of proton spin.

    Nature's Microscopic Masonry: The First Steps in How Thin Protein Sheets Form Polyhedral Shells

    Scientists have for the first time viewed how bacterial proteins self-assemble into thin sheets and begin to form the walls of the outer shell for nano-sized polyhedral compartments that function as specialized factories. The new insight may aid scientists who seek to tap this natural origami by designing novel compartments or using them as scaffolding for new types of nanoscale architectures, such as drug-delivery systems.

    Neutrons Offer Guide to Getting More Out of Solid-State Lithium-Ion Batteries

    A new study conducted at Oak Ridge National Laboratory's Spallation Neutron Source (SNS), has revealed promising results that could drastically boost the performance of solid-state electrolytes, and could potentially lead to a safer, even more efficient battery. Researchers used neutron diffraction (the VULCAN instrument, SNS beam line 7) to conduct an in-depth study probing the entire structure evolution of doped garnet-type electrolytes during the synthesis process to unravel the mechanism that boosts the lithium-ionic conductivity.

    Some Like It Hot: Simulating Single Particle Excitations

    Some Like It Hot: Simulating Single Particle Excitations

    Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Now, for the first time, the interplay between the plasmon mode and the single particle excitation within a small metal cluster has been simulated directly. Researchers with Berkeley Lab used a real-time numerical algorithm to study both the plasmon and hot carrier within the same framework. That is critical for understanding how long a particle stays excited, and whether there is energy backflow from hot carrier to plasmon.

    LUX Experiment Draws Best Picture Yet of What Dark Matter Particles Cannot Be

    LUX Experiment Draws Best Picture Yet of What Dark Matter Particles Cannot Be

    The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of South Dakota, has already proven itself to be the most sensitive dark matter detector in the world. Now scientists have significantly enhanced its ability to look for WIMPs, or weakly interacting massive particles, which are among the leading candidates for dark matter.

    New Results From World's Most Sensitive Dark Matter Detector

    The Large Underground Xenon dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility in the Black Hills of South Dakota, has already proven itself to be the most sensitive detector in the hunt for dark matter, the unseen stuff believed to account for most of the matter in the universe. Now, a new set of calibration techniques employed by LUX scientists has again dramatically improved the detector's sensitivity.

    To Get More Oomph From an Electron Gun, Tip It with Diamondoids

    To Get More Oomph From an Electron Gun, Tip It with Diamondoids

    They sound like futuristic weapons, but electron guns are actually workhorse tools for research and industry: They emit streams of electrons for electron microscopes, semiconductor patterning equipment and particle accelerators, to name a few important uses. Now scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have figured out how to increase these electron flows 13,000-fold by applying a single layer of diamondoids - tiny, perfect diamond cages - to an electron gun's sharp gold tip.

    Titan Helps Researchers Explore Explosive Star Scenarios

    A team led by Michael Zingale of Stony Brook University is exploring the physics of Type Ia supernovas using the Titan supercomputer at the US Department of Energy's (DOE's) Oak Ridge National Laboratory. The team's latest research focuses on a specific class of Type Ia supernovas known as double-detonation supernovas. This year, the team completed a three-dimensional (3-D), high-resolution investigation of the thermonuclear burning a double-detonation white dwarf undergoes before explosion. The study expands upon the team's initial 3-D simulation of this supernova scenario, which was carried out in 2013.
