Strain Partitioning at the Oxide Interface for the Isothermal Phase Transition in Freestanding Tri‐Layers

Advanced Functional Materials, EarlyView.
The metal–insulator transition temperature (TMI) is continuously tuned by the systematic change of relative thickness in VO2 and TiO2 films (tVO2/tTiO2${t_{{\mathrm{V}}{{\mathrm{O}}_2}}}/{t_{{\mathrm{Ti}}{{\mathrm{O}}_2}}}$) in freestanding TiO2/VO2/TiO2 tri‐layers.

Effects of Temperature Annealing on the Intrinsic Transport Mechanisms of Solution Processed Graphene Nanosheet Networks

Advanced Functional Materials, EarlyView.
Unravelling charge transport mechanisms in graphene nanosheet networks: by combining temperature‐dependent conductivity measurements with a Random Resistor Network model, this study identifies a transition from hopping‐dominated conduction to a band‐like transport mechanism.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

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.

Ternary Transistors With Reconfigurable Polarities

Advanced Functional Materials, EarlyView.
Polarity‐reconfigurable ternary transistors are demonstrated using black phosphorus homojunction with asymmetric contacts and split‐gate structures. Suppression of majority carrier injection, while Fowler–Nordheim tunneling of low‐density minority carriers persists, enables a well‐defined intermediate state with improved on/off ratios.
