THE EFFECT OF PLASTICITY IN CRUMPLING OF THIN SHEETS pp25 - 29
Bridging the gap between theoretical and experimental work to understand
the effect of plasticity on the crumpling of thin sheets into a small
volume has proved difficult. A realistic numerical model now makes a
distinction between elastic and elasto-plastic behaviour.

POWER-LAW SCALING AND FRACTAL NATURE OF MEDIUM-RANGE ORDER IN METALLIC
GLASSES pp30 - 34
Understanding the short- and medium-range structure of metallic glasses
remains a difficult challenge. The observation that the medium-range
order has the characteristics of a fractal network may have broader
implications in the understanding of the relation between structure and
mechanical properties in metallic glasses.

TUNABLE MAGNETIC EXCHANGE INTERACTIONS IN MANGANESE-DOPED INVERTED
CORE-SHELL ZnSe-CdSe NANOCRYSTALS pp35 - 40
Manipulating the properties of semiconducting nanostructures through
magnetic doping can lead to interesting fundamental phenomena, as well
as potential spintronics or memory devices. The demonstration that the
magnetic properties of Mn-doped ZnSe dots can be tuned by adjusting the
thickness of a CdSe shell represents a fundamental advance in the field.

HIGHLY CONDUCTIVE [sim]40-nm-LONG MOLECULAR WIRES ASSEMBLED BY STEPWISE
INCORPORATION OF METAL CENTRES pp41 - 46
A long-standing problem with molecular wires is their poor transport
properties. Highly conductive and very long wires have now been
synthesized by incorporating metal centres into rigid molecular
backbones, which shows promise for their use in electronic devices.

PROBING INTERFACIAL EQUILIBRATION IN MICROSPHERE CRYSTALS FORMED BY
DNA-DIRECTED ASSEMBLY pp52 - 55
The growth kinetics and crystallization behaviour of DNA-directed
colloidal systems are not well understood. Now, using experiments and
simulations, a single nucleotide mismatch in DNA strands attached to
two microsphere species enables the kinetics of crystal growth and
segregation as a result of crystallization to be investigated.

SPIN POLARIZATION IN HALF-METALS PROBED BY FEMTOSECOND SPIN EXCITATION
pp56 - 61
It is now shown that femtosecond optical excitation can be used as a
tool to investigate the spin-polarization properties of half-metals,
and provide a clear distinction between those and metals. Such knowledge
is of fundamental importance for the use of these materials in
spintronics applications.

REGULAR ARRAYS OF HIGHLY ORDERED FERROELECTRIC POLYMER NANOSTRUCTURES
FOR NON-VOLATILE LOW-VOLTAGE MEMORIES pp62 - 67
Ferroelectric polymers are of interest for use as memory devices for
all-organic electronics applications. A fast and efficient embossing
technology is now shown not only to lead to high-density arrays of
ferroelectric nanocells but also to significantly improve the
ferroelectric properties of these structures.

Electronically active materials made by the self-assembly of alternating

A METAL-FREE POLYMERIC PHOTOCATALYST FOR HYDROGEN PRODUCTION FROM WATER
UNDER VISIBLE LIGHT pp76 - 80
Hydrogen generated from splitting water using a catalyst and solar
energy is an ideal energy source. A polymeric carbon nitride
photocatalyst that is thermally and chemically stable is now shown to
produce hydrogen from water even in the absence of noble metal catalysts.
