- Freestanding Ultrathin Metallic Nanosheets: Materials, Synthesis, and Applications
Tao Ling, Jing-Jing Wang, Hao Zhang, Shu-Tao Song, Yu-Zhu Zhou, Jiong Zhao and Xi-Wen Du

Free-standing ultrathin metallic nanosheets with atomic thickness are the subject of considerable attention. Many kinds of metallic nanosheets with several atomic layers can be successfully synthesized through well-controlled anisotropic growth. These ultrathin metallic nanosheets display unique physical and chemical properties, and show great potential in biochemical sensing and imaging, industrial catalysis, and magnetic recording devices.
- Large-Scale Precise Printing of Ultrathin Sol–Gel Oxide Dielectrics for Directly Patterned Solution-Processed Metal Oxide Transistor Arrays

Ultrathin and dense metal oxide gate dielectric layers are reported by a simple printing of AlOx and HfOx sol–gel precursors. Large-area printed indium gallium zinc oxide (IGZO) thin-film transistor arrays, which exhibit mobilities >5 cm2 V−1 s−1 and gate leakage current of 10−9 A cm−2 at a very low operation voltage of 2 V, are demonstrated by continuous simple bar-coated processes.

Two-dimensional (2D) porous carbon sheets, which can be synthesized by templating approaches, biomass carbonization, biomass carbonization–activation, in situ activation, etc, are good candidates for supercapacitors due to their advantages in their short ion-transport length and high aspect ratio for electrode packing and electron transport.
- Controlled Assembly of Biocompatible Metallic Nanoaggregates Using a Small Molecule Crosslinker
Desiree Van Haute, Julia M. Longmate and Jacob M. Berlin
Article first published online: 24 JUL 2015 | DOI: 10.1002/adma.201501602
By introducing a capping step and controlling reaction parameters, the assembly of metallic nanoparticle aggregates can be achieved using a small molecule crosslinker. Aggregates can be assembled from particles of varied size and composition and the size of the aggregates can be systematically adjusted. Following cell uptake of 60 nm aggregates, the aggregates are stable and nontoxic to macrophage cells up to 55 × 10−3m Au.
- Measurement of the Charge Carrier Mobility Distribution in Bulk Heterojunction Solar Cells
Jason Seifter, Yanming Sun, Hyosung Choi, Byoung Hoon Lee, Thanh Luan Nguyen, Han Young Woo and Alan J. Heeger
Article first published online: 22 JUL 2015 | DOI: 10.1002/adma.201500416
Charge carrier transport through organic solar cells is fundamentally dispersive due to the disordered structure and complex film morphology within the photoactive layer. A novel application of transient photocurrent and short circuit variable time-delayed collection field measurements is used to reconstruct the complete charge carrier mobility distribution for the photogenerated carriers in optimized organic solar cells.
