Spectrometry reaches mass-consumer simplicity Jul 1, 2015

The first ever spectrometer to use quantum-dot materials demonstrates the possibility of devices as small, cheap and simple as smart-phone cameras.

Technology update

Graphene coating boosts battery performance

The capacity of a lithium-ion battery can be nearly doubled by using an anode made from tiny nanoparticles of silicon wrapped in several layers of graphene.

Tiny magnetite does not undergo the 'Verwey' transition

Fe3O4 particles smaller than 6 nm in size stay conducting.

'Green' nanocapsules kill bacterial biofilms

Silica nanoparticles encapsulating natural essential oils could be used as disinfectants but may also help in wound healing.

Ferroelectric capacitor goes flexible

New device might find applications in wearable electronics, health-monitoring systems and ultradense information-storage systems that mimic the structure of the brain.

Nano-cartography: knowing where to look

Mapping aids navigation. Now a well-stocked tool box of approaches provides information on how electronic, optical, mechanical and magnetic properties vary in nanosystems, with ever more refined techniques for accruing insights into the interplay of different system parameters.

Electron microscopy reaches new heights

(with audio) Researchers gathered at the inauguration of the SuperSTEM 3 electron microscope in Daresbury, UK, told nanotechweb.org about their outlook for the equipment and its high-resolution spectroscopic and spatial capabilities.
