Taking aircraft manufacturing out of the oven
Aerospace engineers at MIT have now developed a carbon nanotube film that can heat and solidify a composite without the need for massive ovens. When connected to an electrical power source, and wrapped over a multilayer polymer composite, the heated film stimulates the polymer to solidify.

Gold by special delivery intensifies cancer-killing radiation
Researchers at Brown and the University of Rhode Island have demonstrated what could become a more precise method for targeting cancer cells for radiation. The method would use cancer-seeking peptides to ferry nanoparticles of gold to the site. The gold then helps focus radiation on the cancer cells.

How many gold atoms make gold metal?
Researchers at the Nanoscience Center at the University of Jyväskylä, Finland, have shown that dramatic changes in the electronic properties of nanometer-sized chunks of gold occur in well-defined size range. Small gold nanoclusters could be used, for instance, in short-term storage of energy or electric charge in the field of molecular electronics.

Graphene looking promising for future spintronic devices
Researchers at Chalmers University of Technology have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim to manufacturing faster and more energy-efficient memory and processors in computers. The findings will be published in the journal Nature Communications.

Erupting electrodes: How recharging leaves behind microscopic debris inside batteries
An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body, and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise. Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries in work appearing in the March issue of the journal Nano Letters.

Engineers now understand how complex carbon nanostructures form
Carbon nanotubes (CNTs) are microscopic tubular structures that engineers 'grow' through a process conducted in a high-temperature furnace. The forces that create the CNT structures known as 'forests' often are unpredictable and are mostly left to chance. Now, a University of Missouri researcher has developed a way to predict how these complicated structures are formed. By understanding how CNT arrays are created, engineers can better incorporate the highly adaptable material into devices and products.

Tunneling across a tiny gap
Researchers at MIT, the University of Oklahoma, and Rutgers University have developed a model that explains how heat flows between objects separated by gaps of less than a nanometer. The team has developed a unified framework that calculates heat transport at finite gaps, and has shown that heat flow at sub-nanometer distances occurs not via radiation or conduction, but through 'phonon tunneling.'

Pavel Levkin is granted Heinz Maier-Leibnitz Prize
The chemist Pavel Levkin of Karlsruhe Institute of Technology is granted the 2015 Heinz Maier-Leibnitz Prize by the German Research Foundation. The prize is considered the highest distinction for young researchers in Germany. Levkin's work focuses on the investigation of cell-surface interactions, the development of biofunctional materials and super-water-repellent surfaces, also on nanoparticles for specific medicine and gene transport. A scientific success of his was the synthesis of lipid-like molecules for gene modification of cells.

Carbon nanotube computing?
In the Journal of Applied Physics, a group of researchers from Durham University in the UK and the University of São Paulo-USP in Brazil describes using single-walled carbon nanotube composites (SWCNTs) as a material in 'unconventional' computing. By studying the mechanical and electrical properties of the materials, they discovered a correlation between SWCNT concentration/viscosity/conductivity and the computational capability of the composite.

Future electronics based on carbon nanotubes
A big barrier to building useful electronics with carbon nanotubes has always been the fact that when they're arrayed into films, a certain portion of them will act more like metals than semiconductors. But now a team of researchers have shown how to strip out the metallic carbon nanotubes from arrays using a relatively simple, scalable procedure that does not require expensive equipment. Their work is described this week in the Journal of Applied Physics.
