Surface Plasmonics: Plasmonic Crystals: A Platform to Catalog Resonances from Ultraviolet to Near-Infrared Wavelengths in a Plasmonic Library (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 4 2010
Mater.
Research in the field of surface plasmonics is finding application in many areas; for example, in data storage, nano-electronics, and biosensing. In their feature article on page 529, H. Gao et al. describe recent progress in manipulating surface plasmons from the ultraviolet to near-infrared wavelengths using nanostructured plasmonic crystals (shown in the cover image), and build a comprehensive library of plasmonic resonances, bringing together for the first time the resonance characteristics of key plasmonic materials.

Solar Cell Blends: High-Resolution Spectroscopic Mapping of the Chemical Contrast from Nanometer Domains in P3HT:PCBM Organic Blend Films for Solar-Cell Applications (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 3 2010
Mater.
The inside cover image presents a near-field spectroscopic map of a P3HT:PCBM solar cell blend film obtaining using a parabolic-mirror-assisted optical microscope. This technique allows for simultaneous recording of both morphological and spectroscopic information, and on page 492 Xiao Wang et al. use it to investigate local molecular distribution, photoluminescence quenching efficiency, and other key properties of the P3HT:PCBM blend film.

Printable Electronics: Foldable Printed Circuit Boards on Paper Substrates (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 1 2010
Mater.
Lightweight and flexible printed circuit boards (PCBs) have been produced by micro-patterning metal on paper substrates, as reported by Siegel et al. on page 28. Paper-based electronic devices can be folded and creased repeatedly, shaped to form three-dimensional structures, integrated with paper-based microfluidic devices, and disposed of by flame (as shown in the cover image).

Ceramic Membranes: Microstructural Engineering of Hydroxyapatite Membranes to Enhance Proton Conductivity (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 24 2009
Mater.
The inside cover image showns a side view of a hydroxyapatite membrane with aligned crystal domains synthesized as described by Liu et al. on page 3941. The microstructure of the membrane is engineered to promote proton transport through orientation of the proton conducting paths. These novel structures have significantly higher proton conductivity than traditional hydroxyapatite ceramics and may offer improved performance in intermediate temperature fuel cells. [source]

Liquid-Crystal Polymers: Liquid-Crystalline Polymer with a Block Mesogenic Side Group: Photoinduced Manipulation of Nanophase-Separated Structures (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 23 2009
Mater.
The inside cover image represents a novel azobenzene liquid-crystalline (LC) polymer with a block mesogenic side group, which exhibits a lamellar structure after annealing in an LC phase. Whereas irradiation with linearly polarized light aligns the lamellae parallel to the polarization, irradiation with unpolarized light erases the surface morphology accompanied by photochemical phase transition, as reported by K. Okano et al. on page 3804. [source]

Nanofibers from Laser Spinning: Laser Spinning of Bioactive Glass Nanofibers (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 19 2009
Mater.
This cover image is a graphical representation of the laser spinning process described by Félix Quintero et al. on page 3084. Laser spinning involves the use of a high power laser to melt a very small volume from a plate of the precursor material. A high speed supersonic gas jet causes the rapid elongation and cooling of the melt, yielding a glass nanofiber. The authors also describe the use of this technique in producing Bioglass nanofibers.

Light-Emitting Electrochemical Cells: The Design and Realization of Flexible, Long-Lived Light-Emitting Electrochemical Cells (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 16 2009
Mater.
A highly functional flexible light-emitting electrochemical cell during operation is depicted in this cover image. By optimizing the composition of the active material and by employing an appropriate operation protocol, as described by Fang et al. on page 2671, more than one month of uninterrupted operation at significant brightness (>100 cd,2 ) and relatively high power conversion efficiency (2 lm W,1 for orange-red emission) is realized.

Superparamagnetic Nanoparticles: Facile Fabrication and Superparamagnetism of Silica-Shielded Magnetite Nanoparticles on Carbon Nitride Nanotubes (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 14 2009
Mater.
The superparamagnetic response of silica-coated magnetite nanoparticles on carbon nitride nanotubes in water is depicted in this cover image. The silica shell helps maintain the superparamagnetic fluid while magnetite nanoparticles on carbon nitride nanotubes without silica layers show a significant degradation of magnetic performance in water. On page 2213, Jeung Ku Kang and co-workers report a facile fabrication of these silica-shielded magnetite nanoparticles on carbon nitride nanotubes via the liquid polyol process. [source]

DNA Detection: Intercalating Dye Harnessed Cationic Conjugated Polymer for Real-Time Naked-Eye Recognition of Double-Stranded DNA in Serum (Adv. Funct.

ADVANCED FUNCTIONAL MATERIALS, Issue 9 2009
Mater.
On page 1371, Liu Bin and Pu Kan-Yi demonstrate multicolor detection of double-stranded DNA in biological media using an intercalating-dye-harnessed cationic conjugated polymer. As demonstrated in the cover image, the intercalating-dye-harnessed polymer emits blue fluorescence both in the absence and presence of single-stranded DNA in serum-containing solution, while its fluorescence gradually turns from blue to dark yellow with increasing double-stranded DNA concentration.

Organic Lasers: The Development of Luminescent Concentrators for Pumping Organic Semiconductor Lasers (Adv. Mater.

ADVANCED MATERIALS, Issue 31 2009
31/2009)
Graham Turnbull and co-workers report on p. 3205 that a luminescent concentrator based on a coumarin dye doped polymer film can be used to reduce the pumping threshold of polymer lasers. To achieve this effect, the edge of the luminescent concentrator is placed in contact with the surface of an MEH-PPV distributed feedback laser. Intense green fluorescence from the edge of the concentrator film is then used to pump the laser (the red laser emission can be seen at the left of the cover image). [source]
