Thomas Just Sørensen and Bo Wegge Laursen are chemists at the University of Copenhagen, Denmark. In a series of publications in well-regarded scientific publications, they have shown that the aza-oxa-trangulenium dyes have the potential to outperform all fluorescent dyes currently used in imaging.
"Our dyes are ten times better, far cheaper and easier to use. The latter I believe, will lead to expanded opportunities and broadened use, by physicians and researchers in developing countries, for example." Says Thomas Just Sørensen.
Visual noise blocks correct diagnosis
Neither expensive, nor difficult or technically demanding
Medical image analysis departments currently devote an incredible amount of time to staining samples, because all samples must be treated with two agents. The use of triangulenium dyes necessitates only one dye. And in contrast with typical dyes, no specialized equipment is needed to see the dyes in tissue samples. A lens from a pair of polarized sunglasses and an ordinary microscope are all that are required.
Open Source dye despite obvious competitiveness
When one compares the advantages of triangulenium dyes against the three million Danish kroner per gram price tag of traditional dyes,(500.000$US)(320.000£) you would expect that the new dye would immediately out-compete its predecessors. However, up to now Sørensen and Laursen have had to give their dye away. "I know that our dye is better, but biologists and physicians don't. Therefore, we are giving the dye away to anyone that wants to perform a comparison test. Someone who needs to assess the health of sick people wouldn't dare to rely on an untested substance. Only when several researchers have shown triangulenium dyes to perform just as effectively as its predecessors can we hope for our substance to become more widely adopted," concludes Thomas Just Sørensen.

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...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
