IN SEARCH OF A THEORY OF SUPERCOOLED LIQUIDS pp831 - 833
Despite the absence of consensus on a theory of the transition from
supercooled liquids to glasses, the experimental observations suggest
that a detail-independent theory should exist.

ELECTRIC-FIELD-INDUCED SUPERCONDUCTIVITY IN AN INSULATOR
pp855 - 858
Increasing the carrier density of a material to the limit at which
superconductivity can be induced has been a long-standing challenge.
This is now realized in an insulator by using an electric-double-layer
gate in an organic electrolyte.

ELECTRON-TRAPPING POLYCRYSTALLINE MATERIALS WITH NEGATIVE ELECTRON
AFFINITY pp859 - 862
The trapping of electrons by grain boundaries in semiconducting and
insulating materials is important for a wide range of devices such as
sensors, and solar and fuel cells. First-principles calculations on
MgO, LiF and NaCl reveal a novel type of electron trapping at grain
boundaries associated with the negative electron affinity of these
materials.

SUSTAINED RELEASE OF A P38 INHIBITOR FROM NON-INFLAMMATORY MICROSPHERES
INHIBITS CARDIAC DYSFUNCTION pp863 - 868
A new polymer is investigated as a drug-delivery vehicle for the
treatment of inflammatory diseases, such as cardiac dysfunction. The
biocompatibility, neutral degradation products and controlled-release
properties of the polyketal microparticles indicate the material's
promising future in inflammation inhibition.

UNIVERSAL LINK BETWEEN THE BOSON PEAK AND TRANSVERSE PHONONS IN GLASS
pp870 - 877
A universal feature of disordered glasses is the appearance of the
so-called boson peak in neutron-scattering experiments. A universal
link between this boson peak and transverse phonons has now been
discovered, and linked to locally favoured structures in the glass.

ELECTRON AND PHONON RENORMALIZATION NEAR CHARGED DEFECTS IN CARBON
NANOTUBES pp878 - 883
Defects can significantly alter the physical properties of materials.
A detailed experimental analysis of defects in carbon nanotubes
enables the relationship between the atomic response and the broadly
available macrosopic behaviour to be captured.

TUNNELLING SPECTRA OF INDIVIDUAL MAGNETIC ENDOFULLERENE MOLECULES
pp884 - 889
To enable the development of devices based on the electrical
manipulation of magnetic molecules, their magnetic state needs to be
conserved when electrical contacts are applied. N@C60 molecules have
now been integrated as part of single-molecule transistors, and their
spin states retained. This achievement may lead towards their use in
high-density information storage and quantum-state control.

PRESSURE-DEPENDENT STRUCTURES OF AMORPHOUS RED PHOSPHORUS AND THE
ORIGIN OF THE FIRST SHARP DIFFRACTION PEAKS pp890 - 899
Characterizing medium-range order in disordered solids and liquids is
crucial for elucidating their structure and transport properties, but
it has so far proved difficult. Using a combination of X-ray
diffraction and Raman scattering, the pressure-dependent and
atomic-void structure of amorphous red phosphorous is determined.

PRINTABLE ION-GEL GATE DIELECTRICS FOR LOW-VOLTAGE POLYMER THIN-FILM
TRANSISTORS ON PLASTIC pp900 - 906
Flexible electronics require that all parts can be printed on plastic
substrates, but finding materials that can act as high-capacitance
dielectrics is a priority. An emerging class of polymer electrolytes,
ion gels, can do the job-with high capacitance and at low voltage.

ULTRATHIN SILICON SOLAR MICROCELLS FOR SEMITRANSPARENT, MECHANICALLY
FLEXIBLE AND MICROCONCENTRATOR MODULE DESIGNS pp907 - 915
In a device design that brings mechanical flexibility to silicon
photovoltaics, Jongseung Yoon, Alfred J. Baca and colleagues
demonstrate how transfer-printing of ultrathin silicon films onto
flexible substrates leads to semitransparent and large-scale arrays
of integrated solar microcells with high solar-energy conversion
efficiencies of 6-8%.

METAL HYDRIDES FOR LITHIUM-ION BATTERIES pp916 - 921
Conversion electrodes for lithium-ion batteries are capable of high
capacity but low energy efficiency and low voltages are problematic.
The electrochemical reactivity of MgH2 with Li shows promise in using
metal-hydride electrodes for both lithium-ion-battery and hydrogen
storage applications.
