SOFT MATTER: SPOTS AND STRIPES pp773 - 774
Darrin J. Pochan
doi:10.1038/nmat2540
Cation binding is shown to trigger mesoscale domain formation within
assembled mixtures of neutral and anionic polymer amphiphiles. The spotted
and striped particles could be used for drug delivery or biomedical
sensing.

QUANTUM DOTS: LONG LIFE IN ZERO DIMENSIONS pp775 - 776
Alessandro Tredicucci
doi:10.1038/nmat2541
Electron relaxation time in semiconductor quantum dots, for terahertz

encouraging result for the development of quantum-dot-based quantum
cascade lasers.

Secondary electron imaging in electron microscopy can achieve resolutions
that compete with transmission electron microscopy, and allows imaging

NANOSCALE MANIPULATION OF THE PROPERTIES OF SOLIDS AT HIGH PRESSURE WITH
RELATIVISTIC HEAVY IONS pp793 - 797
Maik Lang et al.
doi:10.1038/nmat2528
High pressures have been very useful in stabilizing materials that cannot
form at low pressure. However, often high-pressure phases are not stable
when recovered in ambient conditions. Bombardment with high-energy heavy
ions is now shown to stabilize a high-pressure phase of Gd2Zr2O7 in
ambient conditions.

SIGNATURE OF CHECKERBOARD FLUCTUATIONS IN THE PHONON SPECTRA OF A
POSSIBLE POLARONIC METAL La1.2Sr1.8Mn2O7 pp798 - 802
F. Weber et al.
doi:10.1038/nmat2513
In conventional metals, strong interactions between electrons and the
atomic lattice, so-called polarons, often render metals electrically
insulating. In the rare case of polaronic metals, however, polaronic
properties survive even in the metallic state. Neutron-scattering
experiments now reveal that it is through quantum fluctuations that
polarons manifest their presence in these enigmatic materials.

LONG LIFETIMES OF QUANTUM-DOT INTERSUBLEVEL TRANSITIONS IN THE TERAHERTZ
RANGE pp803 - 807
E. A. Zibik et al.
doi:10.1038/nmat2511
Quantum cascade lasers are only one of several applications that could
take advantage of the discrete nature of the energy levels in
semiconductor quantum dots. It is now shown that the relaxation time
between levels is highly sensitive to their energy separation. This
knowledge will be essential for the design and optimization of actual
devices.

IMAGING SINGLE ATOMS USING SECONDARY ELECTRONS WITH AN
ABERRATION-CORRECTED ELECTRON MICROSCOPE pp808 - 812
Y. Zhu, H. Inada, K. Nakamura and J. Wall
doi:10.1038/nmat2532
A new type of scanning electron microscope with aberration correction
allows a resolution of 0.1 nm. The instrument also allows for simultaneous
imaging of atoms on the surface and in the bulk of a sample, which
represents a real breakthrough in the field.

ELECTROSTATIC SPIN CROSSOVER EFFECT IN POLAR MAGNETIC MOLECULES pp813 - 817
Nadjib Baadji et al.
doi:10.1038/nmat2525
Controlling the magnetic properties by using an electric field is a
promising route towards spintronics or magnetic data storage applications.
Using dicobaltocene as a test case, it is now demonstrated theoretically
that an electrostatic potential can be used to control the spin states in
molecules.

THE EFFECT OF THREE-DIMENSIONAL MORPHOLOGY ON THE EFFICIENCY OF HYBRID
POLYMER SOLAR CELLS pp818 - 824
Stefan D. Oosterhout et al.
doi:10.1038/nmat2533
The performance of hybrid solar cells depends critically on the morphology
of both the polymeric and the inorganic components. Electron tomography
is used to resolve the morphology in three dimensions; coupling this
information with three-dimensional exciton-diffusion studies enables
the differentiation of charge generation and transport as
performance-limiting factors.

NITROGEN INTERACTION WITH HYDROGEN-TERMINATED SILICON SURFACES AT THE
ATOMIC SCALE pp825 - 830
Min Dai et al.
doi:10.1038/nmat2514
The ability to replace surface hydrogen by multivalent atoms to form
semiconductors with tailored properties is critical for microelectronic
applications. The mechanistic pathway involved in the nitridation of
H-terminated silicon surfaces using ammonia vapour is now explained.

ONE-DIMENSIONAL IMIDAZOLE AGGREGATE IN ALUMINIUM POROUS COORDINATION
POLYMERS WITH HIGH PROTON CONDUCTIVITY pp831 - 836
Sareeya Bureekaew et al.
doi:10.1038/nmat2526
Anhydrous proton-conducting materials capable of operating at high
temperature are required for fuel-cell applications. Encapsulation of a
proton-carrier imidazole molecule in aluminium porous coordination
polymers in anhydrous conditions results in high proton conductivity
above 100 [degree]C.

THE EFFECT OF NANOMETRE-SCALE STRUCTURE ON INTERFACIAL ENERGY pp837 - 842
Jeffrey J. Kuna et al.
doi:10.1038/nmat2534
The interfacial energy between a macroscopic surface consisting of
different materials and a liquid is independent of the surface structure.
It is now shown that because of the way in which a multicomponent
nanoscale surface affects the solvent-molecule arrangement, it is both
the surface structure and composition that dictate the interfacial energy.

SPOTTED VESICLES, STRIPED MICELLES AND JANUS ASSEMBLIES INDUCED BY LIGAND
BINDING pp843 - 849
David A. Christian et al.
doi:10.1038/nmat2512
Controlled domain formation in block copolymer mixtures or lipid bilayers
could lead to more highly ordered assemblies and delivery of drugs. It
is now shown that mesoscale domain formation within assembled mixtures
of neutral and anionic polymer amphiphiles can be induced by the divalent
cations calcium and copper.
