- Polyethylene Imine as an Ideal Interlayer for Highly Efficient Inverted Polymer Light-Emitting Diodes
Young-Hoon Kim, Tae-Hee Han, Himchan Cho, Sung-Yong Min, Chang-Lyoul Lee and Tae-Woo Lee
Article first published online: 10 MAR 2014 | DOI: 10.1002/adfm.201304163
Efficient and air-stable inverted polymer-light emitting diodes (IPLEDs) can be realized by using insulating polymer electron-injecting interlayers (ILs), branched polyethyleneimine (PEI), and polyethyleneimine ethoxylated (PEIE), giving highest current efficiencies of 13.5 cd A-1 and 12 cd A-1, respectively. Polymer ILs can facilitate electron injection into emitting layer as well as block the exciton quenching.

Wei Zhang, Jian Zhen Ou, Shi-Yang Tang, Vijay Sivan, David D. Yao, Kay Latham, Khashayar Khoshmanesh, Arnan Mitchell, Anthony P. O'Mullane and Kourosh Kalantar-zadeh
Article first published online: 10 MAR 2014 | DOI: 10.1002/adfm.201304064
A new platform described as the liquid metal/metal oxide (LM/MO) framework is introduced. The constituent spherical structures of these frameworks are made of micro- to nanosized liquid metal spheres and nanosized metal oxides. These LM/MO frameworks demonstrate high sensitivity towards low concentrations of heavy metal ions and enhanced solar light driven photocalalytic activities.
- Fabrication and Spatially Resolved Functionalization of 3D Microstructures via Multiphoton-Induced Diels–Alder Chemistry
Alexander S. Quick, Hannah Rothfuss, Alexander Welle, Benjamin Richter, Joachim Fischer, Martin Wegener and Christopher Barner-Kowollik
Article first published online: 10 MAR 2014 | DOI: 10.1002/adfm.201304030
A light-induced Diels–Alder reaction is employed for the fabrication and the spatially resolved surface patterning of 3D microstructures using a direct laser writing setup. Woodpile photonic crystals with a lateral rod spacing of 700–500 nm are fabricated and characterized via SEM, FIB milling, and transmission/reflection spectroscopy. Covalent surface patterning of the KIT-logo is verified using ToF-SIMS.
- Ultrasmall Dispersible Crystalline Nickel Oxide Nanoparticles as High-Performance Catalysts for Electrochemical Water Splitting
Ksenia Fominykh, Johann M. Feckl, Johannes Sicklinger, Markus Döblinger, Sebastian Böcklein, Jürgen Ziegler, Laurence Peter, Jiri Rathousky, Ernst-Wilhelm Scheidt, Thomas Bein and Dina Fattakhova-Rohlfing
Article first published online: 10 MAR 2014 | DOI: 10.1002/adfm.201303600
Ultrasmall, crystalline, and dispersible NiO nanoparticles are prepared for the first time using a solvothermal reaction in tert-butanol. These nanocrystals can be prepared with sizes tunable from 2.5 to 5 nm and are highly efficient catalysts for electrochemical oxygen generation.
- Magnetite Crystal Orientation in Magnetosome Chains
André Körnig, Michael Winklhofer, Jens Baumgartner, Teresa Perez Gonzalez, Peter Fratzl and Damien Faivre
Article first published online: 10 MAR 2014 | DOI: 10.1002/adfm.201303737
2D-X-ray diffraction analyses of aligned magnetotactic bacteria reveal  and  fiber textures along the chain direction as a function of cell species. The  axis appears unfavorable because it represents a magnetic hard axis in magnetite. Calculations show how this can be turned into an effective easy axis for a given particle elongation.
