Since the late 60´s electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage and processing capacities of electronic devices over those used today.
Imagine a pen that 'writes' real electronic circuits capable of conducting electricity and lighting up LEDs. This breakthrough, presented this week at the international fair in Hannover, was achieved by researchers from the Leibniz Institute for New Materials (Germany) with the collaboration of a scientist from Spain. The secret is a hybrid ink formed by gold nanoparticles and a conductive organic polymer.
A Spanish-led team of European researchers at the University of Cambridge has created an electronic device so accurate that it can detect the charge of a single electron in less than one microsecond. It has been dubbed the ‘gate sensor’ and could be applied in quantum computers of the future to read information stored in the charge or spin of a single electron.
Researchers in Spain have discovered that if lead atoms are intercalated on a graphene sheet, a powerful magnetic field is generated by the interaction of the electrons’ spin with their orbital movement. This property could have implications in spintronics, an emerging technology promoted by the European Union to create advanced computational systems.
A research conducted by the Institute for Molecular Science of the Universitat de València and of the Institute for Chemical Technology of the Universitat Politècnica de València and the Spanish National Research Council, confirms for the first time the possibility of modulating the magnetic properties of an inorganic material through organic photoactive molecules activated by light.
Researchers from the Basque centre CIC biomaGUNE and the University of Antwerp (Belgium) have designed nanoparticles with one half formed of gold branches and the other of silicon oxide. They are a kind of Janus particle, so-called in honour of the Roman god with two faces, which could be used in phototherapy in the future to treat tumours.
Researchers from IMDEA-Nanociencia Institute and from Autonoma and Complutense Universities of Madrid (Spain) have managed to give graphene magnetic properties. The breakthrough, published in the journal ‘Nature Physics’, opens the door to the development of graphene-based spintronic devices, that is, devices based on the spin or rotation of the electron, and could transform the electronics industry.
