    Two tilted spiro geometry based thermally activated delayed fluorescence type hosts are developed and implemented as host for organic light-emitting diodes. Record power efficiency of 63.6 lm W−1 and external quantum efficiency (EQE) of 31.2% for Ir(MDQ)2(acac) based device are obtained. Notably, even under ultralow phosphor dopant concentration (0.5 wt%), high power efficiency of around 58 lm W−1 is still achievable.

  2. Tailoring Sodium Anodes for Stable Sodium–Oxygen Batteries

    Shichao Wu, Yu Qiao, Kezhu Jiang, Yibo He, Shaohua Guo and Haoshen Zhou

    Tailored sodium anodes with durable protection films efficiently suppress O2 crossover, electrolyte decay, and dendrite formation. Sodium–oxygen batteries achieve long-term cycling stability and improved safety.

  3. UV-Induced Multilevel Current Amplification Memory Effect in Zinc Oxide Rods Resistive Switching Devices

    Paola Russo, Ming Xiao, Robert Liang and Norman Y. Zhou

    Resistive switching devices made of ZnO rods show multilevel current amplification upon exposure to ultraviolet (UV) light. The rods are grown by cathodic deposition and from the electrical measurements, an improvement of the device's stability under UV irradiation together with a multilevel current amplification behavior induced by the slower photodecay process is observed.

  4. Peripheral Nerve-Derived Matrix Hydrogel Promotes Remyelination and Inhibits Synapse Formation

    Jian-Long Zou, Sheng Liu, Jia-Hui Sun, Wei-Hong Yang, Yi-Wei Xu, Zi-Long Rao, Bin Jiang, Qing-Tang Zhu, Xiao-Lin Liu, Jin-Lang Wu, Calvin Chang, Hai-Quan Mao, Eng-Ang Ling, Da-Ping Quan and Yuan-Shan Zeng

    Decellularized nerve matrix-gel (DNM-G) and decellularized spinal cord matrix-gel (DSCM-G) can recapitulate the microenvironment cues unique to the native tissue functions. In vitro study shows that DNM-G promotes far stronger remyelination activity and reduces synapse formation of the regenerating axons in contrast to DSCM-G; tissue-specific extracellular matrix components correlating biological functions' supporting functional regeneration are investigated.

  5. NixSy Nanowalls/Nitrogen-Doped Graphene Foam Is an Efficient Trifunctional Catalyst for Unassisted Artificial Photosynthesis

    Haiyuan Zou, Bowen He, Panyong Kuang, Jiaguo Yu and Ke Fan

    A trifunctional catalyst based on NixSy nanowalls (NWs) on nitrogen-doped graphene foam (NGF) can be efficiently applied in dye-sensitized solar cells (DSSCs) and overall water splitting. An unassisted artificial photosynthesis device constructed by a NixSy NW/NGF-based tandem DSSC-electrolyzer gives a solar-to-hydrogen efficiency of 3.2%.
