An international consortium of 7 universities and research centres are seeking an alternative to silicon-based microelectronics in using molecules of DNA, which could enable a reduction in size of the current systems by a thousand times. The University of the Basque Country (UPV/EHU) is participating in this project through the research group led by Professor Ángel Rubio Secades of the Department of Materials Physics.
The really innovative nature of this project lies, on the one hand, in the use of all the recognition and self-assembly potential of biological systems, more specifically, using derivatives of DNA such as G4-DNA, M-DNA and PC-DNA with a greater electronic potential than DNA itself (which is by itself an insulator). On the other, it lies in carrying out studies in surface chemistry combined with scanning probe microscopy (SPM) and spectroscopy, the measurement of electrical transport, sophisticated nano-manufacture and theoretical studies of the computational simulation of the stability and properties of synthesised devices and/or motivating new structures that might have a greater potential. In this way the manner of designing nano-wires using these molecular derivatives is being developed. As is the way of controlling the interaction between the molecular electrode and the molecular substrate, seeking a deep understanding of the energy conduction mechanisms of these nano-wires and being able to produce models of nanomolecular devices based on these DNA derivatives.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
