Although immune checkpoint blockade has achieved great success in cancer treatment, its efficacy in breast cancer is limited. Therefore, the identification and evaluation of novel prognostic biomarkers in the immune microenvironment will be very helpful for immunotherapy-based breast cancer treatment.
The high-power and long-pulse operation of tokamak will cause excessive particle flux and heat load on the divertor target plate. The surface of the target plate will be subject to intense sputtering, and the thermal load of the target plate will exceed the material/component limit. The sputtered atoms generated by the damage of the target plate may be transported to the core plasma, degrading the quality of the fusion plasma, and increasing the difficulty of plasma stability control.
Tianhe Core Module, the first part of a planned new space station of China, was successfully launched recently. The core device of the Container-Free Laboratory Cabinet, one of the two cabinets in the cabin, is developed by a collaborated research team of the Institute of Intelligent Machines and the Shanghai Institute of Ceramics.
In recent years, as a strategy for activating nitrogen under ambient conditions, electrochemical reduction of nitrogen to ammonia has shown great potential. To realize efficient electrochemical nitrogen fixation，scientists have been trying to design a reasonable electrocatalyst with the optimal nitrogen adsorption and activation capability.
As the 2022 Beijing Olympic Winter Games is approaching, to secure the water quality of Guanting Reservoir, one of the water resources of the Games, has become an urgent.
