Small is beautiful

During the last two days IBEC has been taking part in 10alamenos9, the second Festival of Nanoscience, at CosmoCaixa museum in Barcelona.

Funded by FECYT, the festival is taking place simultaneously in Barcelona, Saragossa, Bellaterra, San Sebastian and Madrid, and aims to highlight the importance and impact of nanoscience and nanotechnology.
IBEC’s contribution to the programme of exhibitions, workshops, seminars and contests included a Nano Workshop in collaboration with Il·lustraciència, talks by Gabriel Gomila and Samuel Sánchez, and a workshop on drug delivery.

The most efficient single-molecule diode ever made

Researchers have created the most efficient single-molecule diode ever.

Diodes are common in everyday electronic devices, in which they control the current by allowing it to flow in one direction while blocking it in the opposite direction. The researchers, working at the University of Barcelona (UB) and IBEC, have created one of just 1 nanometer in size with a rectification ratio – the ratio of the current that flows in one direction compared to the other – several orders of magnitude higher than previously.
