Achieved by Hebrew University, UCLA scientists
Illustration shows how the “molecular motor” is composed of a molecule made up of two spheres, rotating on a common axis between them. In the double-sphered molecule at right, two carbon atoms (grey) are shown on the left-hand side of both spheres of the molecule. In the molecule at left, the upper sphere of the molecule has rotated counter-clockwise by 144 degrees and locked in position, the result being that the carbon atoms can now be seen in the top sphere on the right-hand side. The other atoms in the illustration are nickel (blue) and hydrogen (pink). The straight bars connecting the atoms represent chemical bonds
A step towards building tiny motors on the scale of a molecule has been demonstrated by researchers at the Hebrew University of Jerusalem and the University of California at Los Angeles (UCLA).
In an article appearing in the current issue of Science magazine, the researchers from the two institutions described how they were able – through light or electrical stimulation – to cause a molecule to rotate on an axis in a controlled fashion, similar to the action of a motor.

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...
