High-efficient drainage technology of shale gas reservoirs with normal pressure in Pengshui Block
Youqicang pingjia yu kaifa, 2020 The shale gas reservoirs in Pengshui Block belong to the normal pressure system, where the spontaneous production fails after hydraulic fracturing. This is due to the relative low energy and productivity of the reservoirs, hence it is necessary to deploy

Multimode Oxide‐Based Optoelectronic Memtransistor for In‐Sensor Vision Processing
Advanced Functional Materials, EarlyView.A multimode optoelectronic memtransistor (OEMT) is demonstrated for vision explainable artificial intelligence (VXAI) hardware. By integrating optical sensing, electrical masking, and non‐volatile memory, the device enables key operations required for generating saliency information.

Advanced Functional Materials, EarlyView.Sodium alginate regulates interfacial ion transport and retention in electrolyte‐gated synaptic transistors. The carboxylate‐rich polymeric network forms a dynamic interfacial ion‐diffusion barrier that facilitates ion injection during programming while suppressing ion back‐diffusion, thereby stabilizing the electrochemically doped channel state.

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
