Dutch researcher Ferry Winter has developed a heterogeneous catalyst for the production of the industrially important solvent methyl isobutyl ketone. With the new catalyst the production process is more environmentally-friendly. The catalyst consists of hydrotalcite, a naturally-occurring clay.
The catalyst developed by Ferry Winter belongs to a new category of catalysts termed activated hydrotalcites. Hydrotalcite is a clay comprised of a mixture of magnesium and aluminium hydroxide and forms a layered compound. After activation the clay can be used as a solid-base catalyst. Winters catalyst is made up of very small hydrotalcite platelets deposited on carbon nanofibres. This structure gives rise to a highly active catalyst, which in terms of catalyst particle size and mechanical strength is ideally suited for industrial applications.

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...
