Space storms could soon be forecast with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth.

Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is traveling at and when it will smash into our planet—even before it has fully erupted from the sun.

CMEs are bursts of gas and magnetic fields sp...

A research team led by Professor Kyu-Young Park from the Graduate Institute of Ferrous & Eco Materials Technology and the Department of Materials Science and Engineering and Kyoung Eun Lee, a PhD candidate, and alumna Yura Kim from the Graduate Institute of Ferrous & Eco Materials Technology at Pohang University of Science and Technology (POSTECH), in collaboration with the POSCO Holdings N.EX.T Hub, has recently demonstrated a single-crystal synthesis technology that significantly extends the lifespan of cathode materials for electric vehicles. This research was published in the online edition of ACS Materials & Interfaces, an international journal in the materials science field.

Lithium (Li) secondary batteries, commonly used in electric vehicles, store energy by converting elect...

Researchers at the University of Cologne have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing / publication in Nature Physics.

A team of experimental physicists led by the University of Cologne have shown that it is possible to create superconducting effects in special materials known for their unique edge-only electrical properties. This discovery provides a new way to explore advanced quantum states that could be crucial for developing stable and efficient quantum computers. Their study, titled ‘Induced superconducting correlations in a quantum anomalous Hall insulator’, has been published in Nature Physics.

Superconductivity is a phenomenon where electricity ...

Researchers from Germany, Italy, and the UK have achieved a major advance in the development of materials suitable for on-chip energy harvesting. By composing an alloy made of silicon, germanium and tin, they were able to create a thermoelectric material, promising to transform the waste heat of computer processors back into electricity.

With all elements coming from the 4th main group of the periodic table, these new semiconductor alloy can be easily integrated into the CMOS process of chip production...
