Two-dimensional layered van der Waals crystals have important application prospects in the fields of flexible electronics, optoelectronics and energy conversion due to their rich electrical, optical, thermoelectric and spin electronic properties. This type of material has intrinsically weak interlayer van der Waals interactions and strong intralayer chemical bonds, which form anisotropic characteristics in structure and performance. Although academic circles have observed macroscale room temperature plasticity in various materials such as InSe, SnSe 2 , GaSe, and defective Bi 2 Te 3 , their tensile strains are generally low. How to improve macroscale tensile plasticity while maintaining excellent electrical properties is a key scientific issue that needs to be solved in the development of high-performance flexible and deformable electronic materials.
Coagulation factor XIa (FXIa) is a key protease in the intrinsic coagulation pathway. It plays a central role in pathological thrombosis and has little impact on the normal hemostasis process. It is a safe target for the development of a new generation of anticoagulant drugs.
Liver fibrosis is a common pathological pathway in most chronic liver diseases, and its essence is the excessive deposition of extracellular matrix in the liver. Macrophages play a central regulatory role in the occurrence and regression of liver fibrosis, but their functional selection mechanism between promoting scar formation and driving scar regression has long been unresolved.
Water isotope separation and identification are key technologies in the fields of medicine, chemistry and life sciences. The molecular size and macroscopic physical and chemical properties of water (H 2 O) and heavy water (D 2 O) are highly similar, and their equilibrium adsorption differences in porous media are limited. It is difficult to determine the cause of isotope differences based on the final adsorption amount alone. Therefore, constructing a thin film with oriented narrow channels, moderate frame flexibility, and proton-electron coupling conduction, and collaboratively analyzing the multi-stage transmission process through mass and electrical signals is the key to realizing real-time identification of the confinement behavior of water isotopes.

Schizophrenia is a neuropsychiatric disease with a complex genetic basis. Although a large number of genetic studies have identified relevant loci, there is still a lack of systematic understanding of which nerve cell types the genetic risk is concentrated on and at what stage of brain development.
PET can observe human metabolism and molecular activities and plays an important role in tumor diagnosis and efficacy evaluation. Recently, the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences and others have made progress in the field of low-count PET imaging.
