Illustration Credit: Cortland Johnson | PNNL Small stockpiles of biomass such as sewage, food waste, and wood chips are often overlooked in visions of future sustainable fuel and chemical production. The dismissal arises because transporting these materials to a large-scale, centralized bio-refinery would require more energy than they produce. Yet […]

A standoff detonation of a nuclear device irradiates an asteroid and deposits energy at and beneath the surface. In this work, two neutron yields (50 kt and 1 Mt) and two neutron energies (14.1 MeV and 1 MeV) were the primary case studies compared side-by-side. The black dots represent the […]

The illustration traces the path of the beam as it passes through the copper radio frequency quadrupole, the black dipole magnet, and the slitted measuring system, and onto the particle detector. The beam’s structural complexity increases when measured at progressively higher resolutions. Credit: ORNL/Jill Hemman A high-intensity accelerator beam is […]

ANIMATION The universe is expanding, and it expands a little faster all the time. Scientists call the speeding up of this expansion cosmic acceleration. This growth increases the distance between points in the universe, just like stretching a rubber sheet would make points on that sheet move further and further […]

STEM (scanning transmission electron microscopy) image of a one-dimensional array of F4TCNQ molecules (yellow-orange) on a gate-tunable graphene device. Credit: Berkeley Lab Removing one charged molecule from a one-dimensional array causes the others to alternately turn ‘on’ or ‘off,’ paving the way for information transfer in tiny circuits. Small electronic […]

Quartz vial (9 mm diameter) containing ~300 micrograms of solid 253Es. The illumination produced is a result of the intense radiation from 253Es. Credit: Haire, R. G., US Department of Energy Experiments by Berkeley Lab scientists on this highly radioactive element reveal some unexpected properties. Since element 99 — einsteinium […]

On the left is a simulated image in which intracluster light is visible as a diffuse haze between discrete peaks of brightness — the galaxies. In observations, as seen in the right, this intracluster light component is largely drowned in noise. Credit: Left image: Jesse Golden-Marx; simulation by The IllustrisTNG. […]

ITER fusion reactor tokamak. Credit: ITER   ANIMATION A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants. In a tokamak, magnetic field coils confine plasma […]

Schematic of light-induced formation of Weyl points in a Dirac material of ZrTe5. Jigang Wang and collaborators report how coherently twisted lattice motion by laser pulses, i.e., a phononic switch, can control the crystal inversion symmetry and photogenerate giant low dissipation current with an exceptional ballistic transport protected by induced […]
