Remote passive drone detection in the presence of strong background noise is challenging, since they are point objects and cannot be recognized by their contour detection. To achieve this goal, scientists in China introduced a new passive single-photon dynamic imaging method using quantum compressed sensing. The method captures the broadband dynamic features of the point object through sparse photon detection and exhibits exceptional performance in noisy environment applications. Due to the dynamic features of the rotor blades of the drone, a successful demonstration of drone detection up to 10 kilometers was achieved.

An international group of chemists led by Johns Hopkins University details a photobiocatalytic approach to carbon-nitrogen bond formation that bypasses the need for fossil fuels, using a copper-substituted nonheme enzyme.

A University of Vermont physicist and his student wondered if there are systems in the atomic scale that behave like the vibrating motion of a guitar string in the Newtonian world. They found that the answer is yes—and solved Lamb's Model at the atomic scale—a 90-year-old problem in quantum physics. 

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.
