Over 100 scientists from 25 research institutions and industries in 12 different European Countries have completed one of the first attempts to understand the risks nanomaterials carry throughout their life-cycle, starting from their fabrication and ending in being discarded or recycled.
A surprising discovery about spin-electron interactions in a specialized semiconductor material - a 'sandwich' of layers with different properties, buffered by a graphene nanoribbon - could potentially offer major advantages in speed, heat dissipation and power consumption in electronic devices.
Scientists have succeeded in growing nanocrystals of gallium arsenide on tiny columns of silicon and germanium. This enables extremely efficient optoelectronic components for important frequency ranges to be realised on silicon chips.
The new method uses a unique polymer coating that contains nanoscale gold particles, in addition to the drug itself. The drug only releases when a light shines on the gold particles, causing the polymeric coating to melt.
