Improving understanding of how the Solar System is formed

12.11.2018

The cosmochemist Professor Alexander Krot (University of Hawaii) is coming to Goethe University as recipient of the Humboldt Research Award.

The observatory on Mauna Kea in Hawaii is world-famous. Less well-known is the fact that the Hawaiian Islands are home to one of the leading institutes for cosmochemistry, the Institute for Geophysics and Planetology (HIGP). One of its scientists is the renowned cosmochemist Professor Alexander Krot, and he is now coming to Goethe University for half a year as Humboldt researcher.

Professor Frank Brenker, geophysicist at Goethe University has been working successfully with Professor Alexandor Kort for years.

This gave Krot the impetus to temporarily take leave from his Institute for Geophyscis and Planetology (HIGP) on Hawaii, where a large number of powerful measuring instruments are at his disposal for the examination of extraterrestrial material. As recipient of the Humboldt Research Award he will be working in Frankfurt am Main for six months.

At the Institute for Geosciences at Goethe University, Krot will be working both in teaching and research. He is especially interested in nanoscale analytical methods using transmission electron microscopy and synchrotron radiation, an area in which Frank Brenker specializes.

Alexander Krot made a particular name for himself through his work on the formation of the first solid bodies of our solar system. Numerous fundamental insights into the childhood of the solar nebula are based on his research. With more than 160 publications, of which 14 are in “Nature” or “Science”, his scientific body of work is impressive.

Krot is not only one of the most influential and successful researchers in the area of cosmochemistry, the science of the formation and distribution of chemical elements and compounds in the solar system – he is also an excellent teacher.

He can now pass on his knowledge directly in several bachelor and master projects at the same time. “It’s a unique opportunity for our students to be able to work with such an internationally successful researcher this early in their careers,” reports Brenker with pleasure.

“Some of them are already familiar with Mr. Krot from his many groundbreaking publications, and it is naturally exciting for them to now be able to discuss things directly with him.”

Current news about science, teaching, and society in GOETHE-UNI online (www.aktuelles.uni-frankfurt.de)
Goethe University is a research-oriented university in the European financial centre Frankfurt The university was founded in 1914 through private funding, primarily from Jewish sponsors, and has since produced pioneering achievements in the areas of social sciences, sociology and economics, medicine, quantum physics, brain research, and labour law. It gained a unique level of autonomy on 1 January 2008 by returning to its historic roots as a "foundation university". Today, it is among the top ten in external funding and among the top three largest universities in Germany, with three clusters of excellence in medicine, life sciences and the humanities. Together with the Technical University of Darmstadt and the University of Mainz, it acts as a partner of the inter-state strategic Rhine-Main University Alliance. Internet: www.uni-frankfurt.de

Im Focus: New Pitt research finds carbon nanotubes show a love/hate relationship with water

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.

New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...

Im Focus: Magnets for the second dimension

If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.

Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...

Im Focus: Distorted Atoms

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.

An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
