  1. Photosynthetic Proteins in Supported Lipid Bilayers: Towards a Biokleptic Approach for Energy Capture

    Lei Wang, Johannes S. Roth, Xiaojun Han and Stephen D. Evans

    Article first published online: 27 FEB 2015 | DOI: 10.1002/smll.201403469

    Progress towards the development of lipid bilayer-based systems for the investigation of membraneproteins is reviewed, with a particular focus on light-capturing proteins. Different methods for the formation of supported lipid bilayers are presented, and some proteins involved in light harvesting and energy transfer in bacterial membranes are discussed.

    Ambient-pressure X-ray spectroscopy reveals the evolution of the Co–Ni core–shell structure during CO2 reduction reactions.

  3. Polyoxometalate-Based Organic–Inorganic Hybrids as Antitumor Drugs

    Lei Fu, Hanqin Gao, Mei Yan, Shouzhu Li, Xinyu Li, Zhifei Dai and Shaoqin Liu

    Article first published online: 26 FEB 2015 | DOI: 10.1002/smll.201500232

    Amphiphilic organic–inorganic POM hybrids are prepared by grafting POMs with long-chain organoalkoxysilane lipids. The hybrids spontaneously assembled into vesicles that exhibit enhanced antitumor activity compared to parent POMs. Such a high antitumor activity is shown to originate from the amphiphilic property of the hybrids, endowing the hybrids with a higher affinity for cell membranes, which enables their easy uptake by the cells.

  4. A Roadmap for Controlled Production of Topological Insulator Nanostructures and Thin Films

    Yunfan Guo, Zhongfan Liu and Hailin Peng

    Article first published online: 26 FEB 2015 | DOI: 10.1002/smll.201403426

    Topological insulators (TIs) with insulating bulk gap and metallic surface states have attracted extensive attention. One big challenge for the study of TIs is the lack of high-quality materials with insulating bulk states. Recent progress in production of TI nanostructures is highlighted, including basic methods and specific methods to reduce bulk carriers, as well as potential applications of TI-based heterostructures.

  5. Moisture Barrier Composites Made of Non-Oxidized Graphene Flakes

    Jungmo Kim, Sung Ho Song, Hyeon-Gyun Im, Gabin Yoon, Dongju Lee, Chanyong Choi, Jin Kim, Byeong-Soo Bae, Kisuk Kang and Seokwoo Jeon

    Article first published online: 26 FEB 2015 | DOI: 10.1002/smll.201403647

    Graphene flakes (GFs) with minimized defects and oxidation ratios are incorporated into polyethylene (PE) to enhance the moisture barrier. GFs produced involving solvothermal intercalation show extremely low oxidation rates (3.17%), and are noncovalently functionalized in situ, inducing strong hydrophobicity. The fabricated composite possesses the best moisture barrier performance reported for a polymer–graphene composite.
