Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

Advanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Design of surface drainage system in Zhangbei coal mine and forecast of gas drainage

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In order to optimize the design of the surface well extraction system at the 11418-working face of Zhangbei Mine, the gas drainage volume at the 11418 working face of Zhangbei Mine is predicted. Based on COSFLOW numerical analysis, this paper predicts the amount of gas drainage and gas emission from the borehole of the 11218 ...

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...
