Traditional phase change materials (PCMs) face challenges such as low thermal conductivity, easy leakage in the molten state, and single functionality, making it difficult to meet the demands for efficient utilization of clean energy and multi-scenario applications. Existing organic/inorganic aerogel-based composites can partially address these issues, but they generally suffer from poor mechanical properties and … Read more
Realization of a Two-Dimensional Weyl Semimetal and Topological Fermi Strings A two-dimensional (2D) Weyl semimetal, akin to a spinful variant of graphene, represents a topological matter characterized by Weyl fermion-like quasiparticles in low dimensions. The spinful linear band structure in two dimensions gives rise to distinctive topological properties, accompanied by the emergence of Fermi string … Read more

The actuator is a device with controllable deformation capabilities and is considered the “heart” of micro-robots. A research team from Tsinghua University has recently developed a film-like micro-actuator that allows micro-robots to achieve continuous shape changes and “lock” specific action forms, enhancing their adaptability to the environment. Researchers stated that by utilizing this actuator and … Read more
