Nokia's Morph nanotechnology concept device to benefit from graphene (w/video)

Without the new materials, i.e. new structures enabled by the novel materials and manufacturing methods it would be impossible to build a Morph kind of device. Graphene has an important role in different components of the new device and the ecosystem needed to make the gateway and context awareness possible in an energy efficient way.

Inexpensive, easy-to-use cotton candy-like glass nanofibers appear to speed healing in initial venous stasis wound trial

Imagine a battlefield medic or emergency medical technician providing first aid with a special wad of cottony glass fibers that simultaneously slows bleeding, fights bacteria (and other sources of infection), stimulates the body's natural healing mechanisms, resists scarring, and-because it is quickly absorbed by surrounding tissue - may never have to be removed in follow-up care.

Nature of bonding determines thermal conductivity

Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. A prerequisite for this is a low thermal conductivity. Phase change materials display a surprisingly low thermal conductivity even in the crystalline state.
