News from the Swiss Nanoscience Institute
Physicists at the University of Basel have succeeded in watching a silver catalyst at work for the first time with the aid of an atomic force microscope. The observations made during an Ullmann reaction have allowed the researchers to calculate the energy turnover and, potentially, to optimize the catalysis. The study, which was performed with experts from Japan and Iran, has been published in the scientific journal "Small".
Scientists at the University of Basel have developed nanoparticles which can serve as efficient contrast agents for magnetic resonance imaging. This new type of nanoparticles produce around ten times more contrast than the actual contrast agents and are responsive to specific environments. The journal Chemical Communications has published these results.
In a quantum computer, quantum states form the smallest information units and replace the binary code used by today’s computers. Until now, these so-called qubits were typically created in a semiconductor using individual electrons, but these were vulnerable to dephasing. Now, an international team
For some pathogens, attack is the best form of defense – they enter immune cells of the human body. However, if they are detected in their hidden niche, the infected cell kills itself to re-expose the pathogens. In the “EMBO Journal” a research group at the University of Basel’s Biozentrum has reported that a protein called gasdermin forms permeable pores in the cell membrane and thus triggers the suicide of the immune cell.
For the first time, researchers at the University of Basel have coupled the nuclear spins of distant atoms using just a single electron. Three research groups from the Department of Physics took part in this complex experiment, the results of which have now been published in the journal Nature Nanotechnology.
The University of Twente in The Netherlands will award four honorary doctorates later this year. Biomechatronics expert Hugh Herr, former politician Neelie Kroes, nano technologist Christoph Gerber and statistician Edward Tufte will receive an honorary doctorate on the occasion of the 55th Dies Natalis of the university, November 25. Ed Brinksma, UT’s Rector Magnificus, announced this today.
