Niobium has long been considered an underperformer in superconducting qubits. Scientists supported by Q-NEXT, a US DOE quantum center led by Argonne, have now engineered a high-quality niobium-based qubit, taking advantage of niobium’s superior qualities.
An interdisciplinary team of experts from the University of Notre Dame, in collaboration with the University of Maryland and University of Utah, have found a way to use artificial intelligence to analyze a household’s passive design characteristics and predict its energy expenses with more than 74 percent accuracy. By combining their findings with demographic data including poverty levels, the researchers have created a comprehensive model for predicting energy burden across 1,402 census tracts and nearly 300,000 households in Chicago.
This study unveils a breakthrough in battery technology, utilizing coffee grounds to produce high-performance P-doped hard carbon anodes for sodium-ion batteries. The optimal doping level of phosphorus (2M H3PO4) enhances electrochemical performance, resulting in a remarkable reversible capacity of 341 mAh g-1 at 20 mA g-1 and an 83% initial Coulombic efficiency. The material's porous structure, increased interlayer spacing, and C-P bonds contribute to its outstanding performance, marking a promising advancement in sustainable energy storage solutions.

More than 75 college students competed to test their skills in the fundamentals of IT and cybersecurity infrastructure in the DOE CyberForce Program’s inaugural Conquer the Hill — Command Edition competition.
A team of scientists at the U.S. Department of Energy’s Argonne National Laboratory have discovered an intriguing “cooperative” behavior among components in batteries that points to an exciting new approach to designing next-generation technologies. The team found that combining two different types of anions, negatively charged ions, with cations, positively charged ions, can significantly improve the overall battery’s performance.
An ingredient in many toothpastes is sodium fluoride, a compound of fluorine. It is added to protect teeth against decay. But compounds containing fluorine have other practical uses that might surprise you. The U.S. Department of Energy’s Argonne National Laboratory scientists have discovered a fluoride electrolyte that could protect a next generation battery against performance decline.
The U.S. Department of Energy’s Argonne National Laboratory scientists have discovered a new pathway to enhance lithium-sulfur batteries, addressing their major drawback of short lifetimes. The discovery, published in Nature, reveals a previously unknown reaction mechanism that overcomes rapid performance decline in lithium-sulfur batteries.
The U.S, Department of Energy’s Argonne National Laboratory researchers have invented and patented a new cathode material that could pave the way for eco- and budget-friendly electric vehicles. The material is inspired by earlier work at Argonne that led to the lithium-ion batteries in the Chevy Volt and Bolt. It could help the supply of low-cost and abundant elements for electric vehicle batteries.
The KIMM has succeeded in conducting the cooling test of a large-capacity ultra-low temperature (hereinafter referred to as ULT) Turbo-Brayton cooling system using a zero GWP refrigerant.
Biomolecules such as amino acids and sugars occur in two mirror-image forms – in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers at Empa and Forschungszentrum Jülich in Germany have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.
The study, published in 'One Earth', is the first to analyse the interplay of electrification and hydrogen in EU climate neutrality scenarios at greater sectoral detail.
Chelsea Chen, a polymer physicist at the Department of Energy’s Oak Ridge National Laboratory, is studying ion transport in solid electrolytes that could help electric vehicle battery charges last longer.
Researchers studying complex phenomena such as the Higgs boson must work with massive experimental data sets. To help, researchers have defined practical FAIR (findable, accessible, interoperable, reusable) principles for data and applied the principles to an open simulated tktk from CERN. FAIR will help humans and computers use large data sets, enable modern computers to process these data sets, and aid the development of artificial intelligence tools.
Jim Robo, a private investor and former chairman and CEO of NextEra Energy, Inc. and NextEra Energy Partners, LP, was elected to the Mayo Clinic Board of Trustees at its quarterly meeting on February 16.
