Dry processed electrodes that do not require expensive and sometimes toxic solvents and instead use polytetrafluoroethylene as a binder could make battery cell production more environmentally friendly and cost-effective. A research team from the MEET Battery Research Center and the Institute of Business Chemistry at the University of Münster has now developed a method for recycling such dry-processed cathodes — an important step toward circular batteries.

We theoretically and experimentally demonstrate that a cylinder with arbitrary cross section, composed of a homogeneous electromagnetic medium featuring nontrivial second Chern numbers c₂ in a synthetic five-dimensional space, host topologically protected intrinsic Higher-order topological insulators (HOTI) type hinge states. Our work introduces the concept of boundary gauge fields and establishes the link between synthetic-space c₂ and real-space HOTI states.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

For the first time, researchers at Umeå University have demonstrated the full capabilities of their large-scale laser facility. In a study published in Nature Photonics, the team reports generating a combination of ultrashort laser pulses, extreme peak power, and precisely controlled waveforms that make it possible to explore the fastest processes in nature.

QUT researchers have identified a new method for incorporating copper ions into a germanium telluride thermoelectric material that significantly improves its ability to convert waste heat into electricity.

Researchers at the College of Design and Engineering at the National University of Singapore have developed a universal co-assembly strategy to produce chiral soft materials that emit strong and stable full-colour circularly polarised luminescence (CPL) across the visible spectrum, including in red, which is a historically challenging target. The hierarchical structures, formed by combining star-shaped polymers with simple chiral additives, exhibit long-term optical stability and mechanical robustness, retaining chiroptical properties for over 100 days. The researchers’ strategy enables the creation of CPL-active materials with potential applications in 3D displays, quantum photonic circuits and anti-counterfeiting technologies.
