1–1 of 1Argonne scientists have used isoporous membranes — membranes with pores of equal size and shape — and recirculation to create separations at the nanoscale that overcome previous limitations.
The NGC 2419 globular cluster contains potassium and magnesium in ratios not found in other, similar globular clusters. Scientists have so far been unable to find the source for this unexpected pattern. However, previous uncertainties in the potassium-hydrogen fusion reactions hindered the predictions of stellar models.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have successfully demonstrated the first 270-kW wireless power transfer to a light-duty electric vehicle. The demonstration used a Porsche Taycan and was conducted in collaboration with Volkswagen Group of America using the ORNL-developed polyphase wireless charging system.
Understanding how materials can convert heat into electricity benefits from a view of those materials at the atomic scale. New research examined how the vibrational modes called phonons work in nanostructures and the interfaces between materials to more fully understand how heat transfers in those materials.
The international collaboration presented their first results with new data in four years, featuring a new low-energy sample of electron neutrinos and a dataset doubled in size.
Researchers at the Argonne National Laboratory have discovered the main reason why and how one of the more promising new cathode materials degrades with repeated cycling of lithium-ion batteries. The team’s new analysis method was key to the discovery.
Quantum information devices need particles to be synchronized in space and time. In nickel molybdate (Ni2Mo3O8), nickel ions (Ni2+) form a triangular array of tetrahedrons and octahedrons with opposing magnetic spins. Electric fields in Ni2Mo3O8 induce parallel alignment of the spins; this alignment changes with time, producing spin excitons.
By unraveling vibrational signatures and observing ion exchanges, an Oak Ridge National Laboratory team revealed how chemical species form in a highly reactive molten salt mixture of aluminum chloride and potassium chloride.
: For the first time, scientists measured radium’s bonding interactions with oxygen atoms in an organic molecule. This finding will aid researchers developing chelators for the delivery of radium isotopes for cancer treatment. The results are important in part because they revealed that radium is less similar than expected to barium, which is often used as a substitute for radium during chelator development.
