- A Perfectly Periodic Three-Dimensional Protein/Silica Mesoporous Structure Produced by an Organism
Igor Zlotnikov, Peter Werner, Horst Blumtritt, Andreas Graff, Yannicke Dauphin, Emil Zolotoyabko and Peter Fratzl

The discovery of perfectly ordered 3D mesoporous protein/silica structure in the axial filament of the marine sponge Monorhaphis chuni is reported. The structure belongs to body-centered tetragonal symmetry system (a = 9.88 nm, c = 10.83 nm) and comprises interconnecting lattices of protein and silica, templated by the self-assembled, enzymatically active protein-silicatein, whose primary function is the precipitation of silica.

Dealloyed nanoporous gold (NPG) dramatically enhances quantum dot (QD) fluorescence by amplifying near-field excitation and increasing radiative decay rate. Originating from plasmonic coupling, the fluorescence enhancement is highly dependent upon the nanopore size of the NPG. In contrast to other nanoengineered metallic structures, NPG exhibits fluorescence enhancement of QDs over a large substrate surface.
- Elimination of Photon Quenching by a Transition Layer to Fabricate a Quenching-Shield Sandwich Structure for 800 nm Excited Upconversion Luminescence of Nd3+-Sensitized Nanoparticles

Nd3+-sensitized quenching-shield sandwich-structured upconversion nanoparticles are reported, which exhibit highly efficient upconversion photoluminescence under excitation by an 800 nm continuous-wave laser. The transition-layer structure is essential to bridge energy transfer from the sensitizer to the activator and simultaneously block energy back-transfer from the activator to the sensitizer. These 800 nm-excited upconversion nanoparticles are a key step toward the development of upconversion nanophosphors for biological applications.
- Tailoring the Molecular Structure to Suppress Extrinsic Disorder in Organic Transistors
Nikolas A. Minder, Shaofeng Lu, Simone Fratini, Sergio Ciuchi, Antonio Facchetti and Alberto F. Morpurgo
Article first published online: 12 DEC 2013 | DOI: 10.1002/adma.201304130
In organic field-effect transistors, the structure of the constituent molecules can be tailored to minimize the disorder experienced by charge carriers. Experiments on two perylene derivatives show that disorder can be suppressed by attaching longer core substituents – thereby reducing potential fluctuations in the transistor channel and increasing the mobility in the activated regime – without altering the intrinsic transport properties.
- 25th Anniversary Article: Artificial Carbonate Nanocrystals and Layered Structural Nanocomposites Inspired by Nacre: Synthesis, Fabrication and Applications
Hong-Bin Yao, Jin Ge, Li-Bo Mao, You-Xian Yan and Shu-Hong Yu
Article first published online: 12 DEC 2013 | DOI: 10.1002/adma.201303470
Artificial carbonate nanocrystals and layered structural nanocomposites: this review focuses on two kinds of nacre-inspired materials, including artificial carbonate nanocrystals and layered structural nanocomposites. An overview of the latest developments and advances in the synthesis, fabrication, and applications of nacre-inspired materials is presented.
