Nanotubes ground to nanoribbons: Experiments demonstrate solid-state carbon nanotube ‘templates’

Researchers on three continents have discovered that functionalized carbon nanotubes, when ground together, react and unzip into nanoribbons. The all solid-state process suggests that nanostructures may serve as templates for controlled chemical reactions.

Nanoparticles naturally fall into left- and right-handed versions

Scientists published first experimental results showing that ordinary nanocrystals possess intrinsic chirality and can be produced under normal conditions as a half-and-half mixture of mirror images of each other. The discovery of this fundamental property in nanocrystals opens new horizons in nano- and bio-technology and medicine, for instance, for such applications as targeted drug delivery.

Graphene heat-transfer riddle unraveled

Researchers have solved the long-standing conundrum of how the boundary between grains of graphene affects heat conductivity in thin films of the miracle substance — bringing developers a step closer to being able to engineer films at a scale useful for cooling microelectronic devices and hundreds of other nano-tech applications.

Hot nanostructures cool faster when they are physically close together

A full description of nanoscale thermal transport has defied understanding for decades. In a new study, researchers uncovered a regime of thermal transport near nanoscale structures, where counterintuitively, nanoscale hot spots cool more quickly when placed close together than when they are widely separated. The results suggest new approaches for addressing the significant challenge of heat management in nanosystems, with design implications for integrated circuits and other uses.

Cellulose from wood can be printed in 3-D

A group of researchers have managed to print and dry three-dimensional objects made entirely by cellulose for the first time with the help of a 3D-bioprinter. They also added carbon nanotubes to create electrically conductive material. The effect is that cellulose and other raw material based on wood will be able to compete with fossil-based plastics and metals in the on-going additive manufacturing revolution, which started with the introduction of the 3D-printer.
