Lithium ion batteries are widely used in various electronic devices due to their advantages such as high energy density, high output power, and long service life.

Professor Xu Haiyang's team from Northeast Normal University published their research work on the design of C-exciton relaxation paths and construction of nested bypasses in single-layer WS2 on Nano Letters. The basic design idea is to construct a band nested bypass for the C exciton to replace the original relaxation path

The Physics Exploration Science and Technology Museum (Physics Exploration Laboratory) is affiliated to the National Physics Experiment Teaching Demonstration Center of the College of Physics. The construction of the laboratory has played a pivotal role in the construction of disciplines and majors, the cultivation of students' majors, and the opening of experimental courses.
