  1. Improved Performance in FeF2 Conversion Cathodes through Use of a Conductive 3D Scaffold and Al2O3 ALD Coating

    Ni-supported 3D FeF2 electrodes are prepared by electrodeposition followed by fluorination. Atomic layer deposition coating of the FeF2 coated with Al2O3 improves its electrochemical properties. The electrode shows good cyclability under high current density and good rate performance, demonstrating that a 3D conductive scaffold, coupled with a thin oxide coating, significantly improves the performance of fluoride-based conversion cathodes.

  2. Resistive Random Access Memory Cells with a Bilayer TiO2/SiOX Insulating Stack for Simultaneous Filamentary and Distributed Resistive Switching

    Ti/2-nm-TiO2/1.5-nm-SiOX/n++Si memristors exhibit unprecedented IV characteristics with double hysteresis. This behavior is related to the coexistence of filamentary and distributed resistive switching, as corroborated by probe station measurements (comparing six different samples), conductive atomic microscopy analyses, and charge transport modeling. The ultrathin nature of the insulators is essential for oxygen scavenging.

  3. An Interplay between Matrix Anisotropy and Actomyosin Contractility Regulates 3D-Directed Cell Migration

    This work describes the generation of anisotropic cell-derived matrices for the study of physiopathological processes. Microfabricated guiding templates are combined with the confluent culture of fibroblasts to generate native-like 3D matrices with controlled architectures. This extracellular matrix model is allowed to unravel the critical interplay between matrix anisotropy with actomyosin contractility during directed 3D cell migration by modulating the locomotion strategy of cells.

  4. Light-Triggered Clustered Vesicles with Self-Supplied Oxygen and Tissue Penetrability for Photodynamic Therapy against Hypoxic Tumor

    Junjie Li, Kai Wei, Shuai Zuo, Yixuan Xu, Zengshi Zha, Wendong Ke, Huabing Chen and Zhishen Ge

    Light-triggered clustered polymeric vesicles loaded with hydrogen peroxide and poly(amidoamine) dendrimer conjugating chlorin e6/cypate (CC-PAMAM) are engineered for photoinduced hypoxic tumor ablation. Upon consecutive 805 and 660 nm laser light irradiation, the vesicles show singlet oxygen-mediated disruption, deep penetration of CC-PAMAM into the poorly permeable tumor, and simultaneously provide oxygen supply.

  5. Fabrication of Nanoporous Alumina Ultrafiltration Membrane with Tunable Pore Size Using Block Copolymer Templates

    Chun Zhou, Tamar Segal-Peretz, Muhammed Enes Oruc, Hyo Seon Suh, Guangpeng Wu and Paul F. Nealey

    Nanoporous inorganic membranes are fabricated from cylinder-forming block copolymer templates. Sequential infiltration synthesis followed by oxygen plasma etching converses polymer domains into uniform alumina pores with tunable pore size. The resulting cylindrical channels are continuous through the film thickness. The created membrane shows excellent protein separation ability. This fabrication route holds great promise in making multifunctional membranes.
