- Dry-Released Nanotubes and Nanoengines by Particle-Assisted Rolling
Jinxing Li, Jing Zhang, Wei Gao, Gaoshan Huang, Zengfeng Di, Ran Liu, Joseph Wang and Yongfeng Mei
Article first published online: 24 MAY 2013 | DOI: 10.1002/adma.201301208

Surface tension of self-assembled metal nanodroplets can be applied to overcome the deformation barriers of strain-engineered nanomembranes and produce extremely nanoscale tubes. Aggregated nanoparticles stress nanomembranes and subsequently integrate on the walls of rolled-up nanotubes, which can speed up the tubular engines owing to the enhanced electrocatalytic activity.
- Thousand-Fold Increase in Optical Storage Density by Polychromatic Address Multiplexing on Self-Assembled DNA Nanostructures
Mohammad D. Mottaghi and Chris Dwyer
Article first published online: 24 MAY 2013 | DOI: 10.1002/adma.201301141

A super-resolution optical storage technique enabled by DNA nanotechnology and the design of resonance energy transfer (RET) networks are demonstrated. The enhancement in storage density stems from non-linear interactions between excitons on the nanostructured RET circuits, which permit large-scale multiplexing with a small set of addressing wavelengths and a single output channel.
- Highly Conductive SrVO3 as a Bottom Electrode for Functional Perovskite Oxides
Jarrett A. Moyer, Craig Eaton and Roman Engel-Herbert
Article first published online: 24 MAY 2013 | DOI: 10.1002/adma.201300900

Stoichiometric SrVO3 thin films grown by hybrid molecular beam epitaxy are demonstrated, meeting the stringent requirements of an ideal bottom electrode material. They display an order of magnitude lower room temperature resistivity and superior chemical stability, compared to the commonly employed SrRuO3, as well as atomically smooth surfaces. Excellent structural compatibility with perovskite and related structures renders SrVO3 a high performance electrode material with the potential to promote the creation of new functional oxide electronic devices.
- Titania Woodpiles with Complete Three-Dimensional Photonic Bandgaps in the Visible
Andreas Frölich, Joachim Fischer, Thomas Zebrowski, Kurt Busch and Martin Wegener
Article first published online: 24 MAY 2013 | DOI: 10.1002/adma.201300896

Titania woodpile photonic crystals are fabricated by a combination of stimulated-emission depletion direct laser writing and a novel titania double-inversion procedure. The procedure relies on atomic-layer deposition which is also used to fine-tune the template geometry to maximize the gapsize. Angle- and polarization-resolved transmittance spectroscopy and a comparison with theory provide evidence for the first complete photonic bandgap in the visible.
- Triplet Harvesting with 100% Efficiency by Way of Thermally Activated Delayed Fluorescence in Charge Transfer OLED Emitters
Fernando B. Dias, Konstantinos N. Bourdakos, Vygintas Jankus, Kathryn C. Moss, Kiran T. Kamtekar, Vandana Bhalla, José Santos, Martin R. Bryce and Andrew P. Monkman
Article first published online: 24 MAY 2013 | DOI: 10.1002/adma.201300753

Triplet harvesting with 100% efficiency is obtained via thermal assisted delayed fluorescence (TADF). The key role played by intramolecular charge transfer (ICT), lone pair electrons, and molecular structure in achieving this high efficiency in a series of ICT molecules is elucidated. Results show the complex photophysics of efficient TADF materials and give clear guidelines for designing new emitters.
