  1. Hierarchical Ordering of Quantum Dots and Liquid with Tunable Super-Periodicity into High Aspect Ratio Moiré Superlattice Structure

    Soo-Yeon Cho, Hwan-Jin Jeon, Jong-Seon Kim, Jong Min Ok and Hee-Tae Jung

    Article first published online: 1 SEP 2014 | DOI: 10.1002/adfm.201401981

    A powerful new method is reported for fabricating complex lateral superlattice structures with 10 nm resolution, using the moiré fringe and secondary sputtering lithography. A large assortment of moiré superstructures can be easily fabricated by a simple rotation of the periodic layer. These superlattice structures widen the range of application of moiré patterns to not only the fields of photonics or optical characterization tools, but also to functional nano-materials trapping and ordering.

  2. Ultra-Thin Self-Assembled Protein-Polymer Membranes: A New Pore Forming Strategy

    Self-assembled membranes offer a promising alternative for conventional membrane fabrication, especially in the field of ultrafiltration. Here a new pore-making strategy is introduced involving stimuli responsive protein-polymer conjugates self-assembled across a large surface area using drying-mediated interfacial self-assembly. The membrane is flexible and assembled on porous supports. This approach diversifies membrane technology generating a platform for “smart” self-assembled membranes.

  3. Nanostructured Pseudocapacitors Based on Atomic Layer Deposition of V2O5 onto Conductive Nanocrystal-based Mesoporous ITO Scaffolds

    Iris E. Rauda, Veronica Augustyn, Laura C. Saldarriaga-Lopez, Xinyi Chen, Laura T. Schelhas, Gary W. Rubloff, Bruce Dunn and Sarah H. Tolbert

    Article first published online: 1 SEP 2014 | DOI: 10.1002/adfm.201401284

    Nanostructured pseudocapacitors are created by coating a conductive scaffold, made through solution-phase templating of ITO nanocrystals, with a conformal layer of vanadium oxide. The materials combine intrinsic electrical conductivity, porosity for solvent diffusion, and short solid-state Li+ diffusion distance. By tuning the vanadia thickness, redox reactions are dominantly pseudocapacitive for vanadia layers up to 7 nm thickness.

  4. Functional Selenium Nanoparticles Enhanced Stem Cell Osteoblastic Differentiation through BMP Signaling Pathways

    Chuping Zheng, Jinsheng Wang, Yanan Liu, Qianqian Yu, Ying Liu, Ning Deng and Jie Liu

    Article first published online: 1 SEP 2014 | DOI: 10.1002/adfm.201401263

    Ru@Se, a good biocompatible nanoparticle, can be uptaken by human umbilical cord mesenchymal stem cells and can enhance the osteogenic differentiation of HUMSCs through the Smad-dependent BMP signaling pathway. The activation of BMP pathway induces the Smad1/5 protein phosphorylation. p-Smad1/5 combines with Smad 4 and translocates into the nucleus to promote the expression of the osteogenesis specific genes, such as BMP, OCN, OPN, thus driving HUCMSCs to differentiate into osteoblasts.

  5. Ultrasmall Graphene Oxide Supported Gold Nanoparticles as Adjuvants Improve Humoral and Cellular Immunity in Mice

    Yuhua Cao, Yufei Ma, Mengxin Zhang, Haiming Wang, Xiaolong Tu, He Shen, Jianwu Dai, Huichen Guo and Zhijun Zhang

    Article first published online: 1 SEP 2014 | DOI: 10.1002/adfm.201401358

    Gold nanoparticles in situ grown on ultra­small graphene oxide (usGO) are decorated with antigen ovalbumin (OVA) through physically adsorbing and Au-S bonding. The usGO-Au@OVA composites can efficiently stimulate RAW264.7 cells to secrete tumor necrosis factor-α and promote an OVA-specific antibody response, CD8+ T cells proliferation, and different cytokines secretion, thus demonstrating the capability to promote potent humoral and cellular immune responses.
