Northwestern scientists develop first liquid nanolaser
Northwestern University scientists have developed the first liquid nanoscale laser. And it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a 'lab on a chip' for medical diagnostics. In addition to changing color in real time, the liquid nanolaser has additional advantages: it is simple to make, inexpensive to produce and operates at room temperature.

Ultra-sensitive sensor detects individual electrons
A Spanish-led team of European researchers at the University of Cambridge has created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the 'gate sensor' and could be applied in quantum computers of the future to read information stored in the charge or spin of a single electron.

Mechanical cloaks of invisibility -- without complicated mathematics
A honeycomb is a very stable structure. A larger hole, however, jeopardizes stability. What might a honeycomb look like, which survives external forces in spite of a hole? Such stable types of constructions might be useful in architecture or construction. So far, the mathematical expenditure required has been high and did not lead to success. Researchers of Karlsruhe Institute of Technology have found a principle that facilitates the mathematical approach and produces promising results.

Pseudoparticles travel through photoactive material
Researchers of Karlsruhe Institute of Technology have unveiled an important step in the conversion of light into storable energy: together with scientists of the Fritz Haber Institute in Berlin and the Aalto University in Helsinki, Finland, they studied the formation of so-called polarons in zinc oxide. The pseudoparticles travel through the photoactive material until they are converted into electrical or chemical energy at an interface.

Scientists use nanoscale building blocks and DNA 'glue' to shape 3-D superlattices
Taking child's play with building blocks to a whole new level-the nanometer scale-scientists at the US Department of Energy's Brookhaven National Laboratory have constructed 3-D 'superlattice' multicomponent nanoparticle arrays where the arrangement of particles is driven by the shape of the tiny building blocks. The method uses linker molecules made of complementary strands of DNA to overcome the blocks' tendency to pack together in a way that would separate differently shaped components.

Nanotech-enabled moisturizer speeds healing of diabetic skin wounds
A new high-tech but simple ointment applied to the skin may one day help diabetic patients heal stubborn and painful ulcers on their feet, Northwestern University researchers report. They are the first to develop a topical gene regulation technology that speeds the healing of ulcers in diabetic animals. The scientists combined spherical nucleic acids with a common commercial moisturizer to create a way to topically knock down a gene known to interfere with wound healing.

Phonons, arise!
The creation of devices to control phonons -- elusive atomic vibrations that transport heat energy in solids at speeds up to the speed of sound -- has taken a step forward when researchers successfully altered the thermal conductivity of a widely used commercial material, using only a simple nine-volt battery.

CWRU researcher awarded $500,000 NSF CAREER grant
A Case Western Reserve University researcher has won a $500,000 National Science Foundation grant to create tiny sensors capable of detecting insecticides in Lake Erie or determining subtypes of human cancers. The sensors are designed to detect multiple cancer markers or environmental hazards at the same time and with greater sensitivity than what's currently available. The results could be used for personalized medicine or to more quickly identify pollutants and begin subsequent clean-up efforts.

Nature: Low-reflection wings make butterflies nearly invisible
The effect is known from the smart phone: Sun is reflected by the display and hardly anything can be seen. In contrast to this, the glasswing butterfly hardly reflects any light in spite of its transparent wings. As a result, it is difficult for predatory birds to track the butterfly during the flight. Researchers of KIT under the direction of Hendrik Hölscher found that irregular nanostructures on the surface of the butterfly wing cause the low reflection.

Surface matters: Huge reduction of heat conduction observed in flat silicon channels
Combining state-of-the-art realistic atomistic modelling and experiments, the paper describes how thermal conductivity of ultrathin silicon membranes is controlled to large extent by the structure and the chemical composition of their surface. A detailed understanding of the connections of fabrication and processing to structural and thermal properties of low-dimensional nanostructures is essential to design materials and devices for phononics, nanoscale thermal management, and thermoelectric applications.

'Holey' graphene for energy storage
Engineers at the University of California, San Diego have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research, published recently online in the journal Nano Letters, may provide a better understanding of how to improve the energy storage ability of capacitors for potential applications in cars, wind turbines, and solar power.

Advances in molecular electronics: Lights on -- molecule on
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf and the University of Konstanz are working on storing and processing information on the level of single molecules to create the smallest possible components that will combine autonomously to form a circuit. As recently reported in the academic journal Advanced Science, the researchers can switch on the current flow through a single molecule for the first time with the help of light.
