Gas Drainage Monitoring at Each Drilling Site. Gas drainage from virgin area by in-seam boring. (1st Report).

Shigen-to-Sozai, 1992
Continuous measurement on gas drainage was carried out at 22 drilling sites of No.1 and No.3 slope area in Minami-Oyubari coal mine. In this coal mine, methane drainage method from seam-road using each drilling site where 40-60 boreholes were drilled as gas drainage area has been developed.The results obtained are as follows.1) Patterns of gas drainage

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 ...

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

Advanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)
