Advanced Functional Materials, EarlyView.Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

An improved opportunistic group replacement maintenance strategy for wind turbines
Energy Science & Engineering, 2020 In traditional opportunistic group replacement maintenance (OGRM) strategy for wind turbines, the reliability thresholds of different subassemblies are set the same and its two‐step optimization for maintenance cost is diseconomy.

Advanced Functional Materials, EarlyView.In this work, a reconfigurable T‐CMOS inverter based on vertically stacked MoS2 and WSe2 MOSFETs with a gate‐tunable MoS2 resistor, enabling stable ternary logic, is demonstrated. The T‐CMOS inverter supports electrical switching between ternary and binary modes and is further extended to implement ternary NAND (NMIN) and NOR (NMAX) logic gates ...
