Zeolitic imidazolate framework-8 (ZIF-8)/WS 2 composite 2D membrane was constructed by in-situ growth of ZIF-8 in the interlayer of WS 2 laminar membrane. The growth of ZIF-8 nanoparticles in WS 2 membrane expanded the interlayer spacing, and endowed WS 2 membrane with fixed interlayer spacing...

In the process of geothermal well drilling, the high-temperature rock in the reservoirs is cooled by different cooling media, which leads to the change of mechanical properties, affecting the rock-breaking efficiency of the bit. Sandstone and granite were taken as the research objects and heated...
