    A programmed liposomal vesicle responsive to the endogenous enzyme, near-infrared light, and temperature is presented. The vesicles can overcome the multiple biological barriers to achieve deep tumor penetration, increased cellular uptake, and intracellular ultrafast drug release. The vesicles coloaded with two chemotherapeutics can be used for combination of photodynamic therapy and chemotherapy of triple negative breast cancer.

  2. Enhanced Electrocatalysis via 3D Graphene Aerogel Engineered with a Silver Nanowire Network for Ultrahigh-Rate Zinc–Air Batteries

    Shang Hu, Ting Han, Chao Lin, Weikai Xiang, Yonghui Zhao, Peng Gao, Fuping Du, Xiaopeng Li and Yuhan Sun

    X-ray computed microtomography (X-ray μCT) reveals the macrodistribution of active phase (i.e., Ag) and supermacroporous structure in the self-assembled graphene aerogel for the first time. The interconnected 3D Ag network is the key to achieve high oxygen reduction reaction activity and utrahigh rate performance in Zn–air batteries.

  3. Solution-Processed Extremely Efficient Multicolor Perovskite Light-Emitting Diodes Utilizing Doped Electron Transport Layer

    Khan Qasim, Baoping Wang, Yupeng Zhang, Pengfei Li, Yusheng Wang, Shaojuan Li, Shuit-Tong Lee, Liang-Sheng Liao, Wei Lei and Qiaoliang Bao

    A specially designed n-type semiconductor consisting of Ca-doped ZnO nanoparticles is used as the electron transport layer (ETL) in high-performance multicolor perovskite light-emitting diodes fabricated using an all-solution process. The strategy of using a tunable ETL in combination with a solution process pushes perovskite-based materials a step closer to practical application in multicolor light-emitting devices.

  4. Evidence and Effect of Photogenerated Charge Transfer for Enhanced Photocatalysis in WO3/TiO2 Heterojunction Films: A Computational and Experimental Study

    Carlos Sotelo-Vazquez, Raul Quesada-Cabrera, Min Ling, David O. Scanlon, Andreas Kafizas, Pardeep Kumar Thakur, Tien-Lin Lee, Alaric Taylor, Graeme W. Watson, Robert G. Palgrave, James R. Durrant, Christopher S. Blackman and Ivan P. Parkin

    Advanced nanostructured WO3/TiO2 heterojunction films are deposited using chemical vapor deposition methods. Against common observation, this system shows an unusual electron transfer from WO3 to TiO2, as proven by theoretical and experimental standpoints. The advantageous electronic synergy within a high-surface-area substrate promotes its photocatalytic properties showing record-high efficiencies for the degradation of organic pollutants.

  5. Ultrathin MnO2/Graphene Oxide/Carbon Nanotube Interlayer as Efficient Polysulfide-Trapping Shield for High-Performance Li–S Batteries

    Weibang Kong, Lingjia Yan, Yufeng Luo, Datao Wang, Kaili Jiang, Qunqing Li, Shoushan Fan and Jiaping Wang

    Version of Record online: 24 MAR 2017 | DOI: 10.1002/adfm.201606663

    Ultrathin MnO2/graphene oxide/carbon nanotube (G/M@CNT) sandwiched interlayer with synergetic effects of graphene oxide sheets, MnO2 nanoparticles, and superaligned carbon nanotube films, significantly alleviates polysulfide shuttling and improves the cycling stability and rate performance of Li–S batteries. Self-discharge and passivation layer formation on the anode are greatly suppressed by the excellent polysulfide-trapping ability of the G/M@CNT interlayer.
