Chemists make new silicon-based nanomaterials
Chemists from Brown University have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon.

Designer's toolkit for dynamic DNA nanomachines
Researchers at the Technische Universitaet Muenchen have demonstrated a new approach to joining -- and reconfiguring -- modular DNA building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly. The team, led by 2015 Leibniz Prize awardee professor Hendrik Dietz, published their results in Science.

ORNL-led team demonstrates desalination with nanoporous graphene membrane
Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy's Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

Nanorobotic agents open the blood-brain barrier, offering hope for new brain treatments
Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. The research is important as currently 98 percent of therapeutic molecules are also unable to cross the blood-brain barrier.

Sensor cable monitors fences of all kinds and can even detect low-level drone fly-bys
Fenced-in areas, such as airports, nuclear power stations, industrial sites, or private plots of land, can now be monitored thanks to novel sensor technology that has been developed by a team of experimental physicists, led by Professor Uwe Hartmann at Saarland University. The sensors respond immediately as soon as someone tries to climb over or cut through the fence, providing information on the precise location of the security breach.

Building shape inspires new material discovery
Physicists inspired by the radical shape of a Canberra building have created a new type of material which enables scientists to put a perfect bend in light. The creation of a so-called topological insulator could transform the telecommunications industry's drive to build an improved computer chip using light.

Catching and releasing tiny molecules
Employing an ingenious microfluidic design that combines chemical and mechanical properties, a team of Harvard scientists has demonstrated a new way of detecting and extracting biomolecules from fluid mixtures. The approach requires fewer steps, uses less energy, and achieves better performance than several techniques currently in use and could lead to better technologies for medical diagnostics and chemical purification.

Have researchers discovered the sound of the stars?
A chance discovery by a team of researchers, including a University of York scientist, has provided experimental evidence that stars may generate sound. The study of fluids in motion -- now known as hydrodynamics -- goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a plasma target, the team observed something unexpected.

First proof of isolated attosecond pulse generation at the carbon K-edge
Nature Communications has published a study in which ICFO researchers have been able to demonstrate, for the first time, the generation of isolated attosecond pulses at the water window. This achievement permits tracking and visualizing electronic motion with element specificity, i.e. bond formation and breaking during a chemical reaction, exciton dynamics in organic solar cells or the occurrence of ultrafast magnetism.

New optical materials break digital connectivity barriers
In our increasingly networked world, we need much faster computer components to support enormous amounts of data transfer and data processing. A new study from Tel Aviv University finds that new optical materials could serve as the nuts and bolts of future ultra-high-speed optical computing components. These 'nonlinear metamaterials,' which possess physical capabilities not found in nature, may be the building blocks that allow major companies like IBM and Intel to move from electronic to optical computing.
