A High-Energy Density And Long-Life Initial-Anode-Free Lithium Battery by Ingrid Fadelli

Lithium-metal batteries (LMBs), an emerging type of rechargeable lithium-based batteries made of solid-state metal instead of lithium-ions, are among the most promising high-energy-density rechargeable battery technologies. Although they have some advantageous characteristics, these batteries have several limitations, including a poor energy density and safety-related issues. In recent years, researchers have tried to overcome these limitations […]

Making Clean Hydrogen Is Hard, But Researchers Just Solved A Major Hurdle by University of Texas at Austin

For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source—splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low […]

Researchers Discover A New Inorganic Material With Lowest Thermal Conductivity Ever Reported by University of Liverpool

This new material, with two combined arrangements, has a much lower thermal conductivity than either of the parent materials with just one arrangement. This unexpected result shows the synergic effect of the chemical control of atomic locations in the structure, and is the reason why the properties of the whole structure are superior to those […]

Solar Storms Are Back, Threatening Life As We Know It On Earth by Brian K. Sullivan

Solar storms have their roots in an 11-year cycle that shifts the polarity of the sun’s magnetic field. The magnetic forces at work on the sun get tangled during the process, and can punch out through the surface, sending the sun’s plasma into outer space and potentially triggering storms on Earth. The most powerful geomagnetic […]
