- 3D Printing of Graphene Aerogels
Qiangqiang Zhang, Feng Zhang, Sai Pradeep Medarametla, Hui Li, Chi Zhou and Dong Lin
Article first published online: 10 FEB 2016 | DOI: 10.1002/smll.201503524
3D printing of a graphene aerogel with true 3D overhang structures is highlighted. The aerogel is fabricated by combining drop-on-demand 3D printing and freeze casting. The water-based GO ink is ejected and freeze-cast into designed 3D structures. The lightweight (<10 mg cm−3) 3D printed graphene aerogel presents superelastic and high electrical conduction.
- Recent Advances in Organic Photovoltaics: Device Structure and Optical Engineering Optimization on the Nanoscale

Recent advances in organic photovoltaics are highlighted, with special attention on the progress in device architecture and the optical engineering approaches that lead to improved electrical and optical characteristics in these devices. In particular, various successful strategies for light wave distribution, modulation, and absorption promotion inside the devices by incorporating periodic nanopatterns/nanostructures or incorporating metallic nanomaterials and nanostructures are highlighted.
- TiO2 Nanorod Array Constructed Nanotopography for Regulation of Mesenchymal Stem Cells Fate and the Realization of Location-Committed Stem Cell Differentiation
Jichuan Qiu, Jianhua Li, Shu Wang, Baojin Ma, Shan Zhang, Weibo Guo, Xiaodi Zhang, Wei Tang, Yuanhua Sang and Hong Liu
Article first published online: 9 FEB 2016 | DOI: 10.1002/smll.201503946
Location-committed osteogenic differentiation of mesenchymal stem cells (MSCs) is realized on a patterned TiO2 ceramic (smooth surface) and TiO2 nanorod array (nanotopography surface). The TiO2 nanorod array promotes osteogenic differentiation, while TiO2 ceramic facilitates self-renewal of MSCs. A route using surface nanotopography constructed by biocompatible TiO2 to control the self-renewal or osteogenic differentiation behaviors of MSCs is demonstrated.
- Chemically Functionalized, Well-Dispersed Carbon Nanotubes in Lithium-Doped Zinc Oxide for Low-Cost, High-Performance Thin-Film Transistors
Gi-Cheol Son, Sang-Soo Chee, Ji-Hyun Jun, Myungwoo Son, Sun Sook Lee, Youngmin Choi, Sunho Jeong and Moon-Ho Ham
Article first published online: 9 FEB 2016 | DOI: 10.1002/smll.201503478
Surface-functionalized carbon nanotubes (CNTs) are introduced into lithium-doped ZnO thin-film transistors (TFTs) as an alternative to the conventional incorporation of an expensive element, indium. The crucial role of surface functionalization of CNTs is clarified with the demonstration of indium-free ZnO-based TFTs with a field-effect mobility of 28.6 cm2 V−1 s−1 and an on/off current ratio of 9 × 106 for low-cost, high-performance electronics.
- Subcompartmentalized Nanoreactors as Artificial Organelle with Intracellular Activity
Bo Thingholm, Philipp Schattling, Yan Zhang and Brigitte Städler
Article first published online: 8 FEB 2016 | DOI: 10.1002/smll.201502109
Subcompartmentalized nanoreactors with loaded glucose oxidase in their liposomal subunits and coated with poly (dopamine) are assembled. The uptake of the nanoreactors by macrophages and endothelial cells depends on the surface coating and applied shear stress. The viability of macrophages is reduced when these nanoreactors, internalized by the macrophages, convert externally added glucose into hydrogen peroxide.
