A warm welcome to our new postdoc Dr. Dila Kaya.

Dila received her M.Sc., and Ph.D. degrees in the Physical Chemistry program of Yildiz Technical University, Istanbul, Turkey. So far in her career, she mainly focused on ion-track etching and the applications of synthetic nanopores. Some of these applications are based on either resistive-pulse or ion-current rectification sensing paradigms using single nanopores for the detection of various analytes including biomaterials, nanoparticles and metal ions. She also has experience on tailoring nanopore geometry and surface groups as well as mass transport of analytes utilizing multiporous membranes. She joined us at GSI as a postdoc scientist to focus on the fabrication and design of nanopores to be used as protein crystallizing media for in situ diffraction data collection.

We kindly welcome Dr. Vishnu Chauhan, who joined our group as postdoc in October 2022.

Vishnu is the awardee of a Post-Doctoral Industrial Fellowship for one year, co-funded by the Department of Science and Technology of the Indian Government and the BMBF. He earned his Ph.D. in physics from Guru Gobind Singh Indraprastha University, Delhi, where he gained experience on ion beam irradiation effects and defect formation in metal oxides and nanocomposite thin films for various applications. During his stay at GSI, his research will concentrate on the synthesis and characterization of low-dimensional oxide materials.

Verena Velthaus was awarded the "Ebara Prize for Young Researchers” for her outstanding oral presentation at the International Vacuum Congress 2022 in Japan. In her talk, Verena described the main results of her dissertation project on “Mitigation of swift heavy ion-induced desorption by pre-cleaning and thermal annealing processes”.

Congratulation to our recent PhD

In July 2022, Philipp Bolz successfully defended his PhD thesis with the title

“Analysis of radiation resistance of carbon-based materials for accelerator components”.

We also congratulate him on the new position in industry and wish him all the best for this new challenge.

Dr. Vanina Cayón has recently joined the Materials Research group as a scientist to work on the design of antiviral surfaces using virus inactivation technologies. She has a Ph.D. in Inorganic Chemistry from the National University of La Plata (Argentina), where she gained experience from organic synthesis to conformational and structural characterization of molecules by various spectroscopic techniques supported by chemical quantum calculations. As a postdoc (Soft Matter Laboratory - INIFTA, Argentina) and in collaboration with GSI researchers, she focused on the investigation and rational design of nanofluidic devices based on track-etched solid-state nanochannels. At GSI, she plans to continue her training as a researcher in the field of materials for biosensing.

In August 2020, Dr. Frieder Koch joined the materials research group as a beamline scientist for the M-branch. With a background in X-ray optics and nanofabrication, he has worked on experiments at numerous international large scale research facilities, most recently as a postdoc in a collaboration between the Swiss Paul Scherrer Institute and the French Synchrotron Soleil. At GSI, he focuses on online, multimodal experiments involving diffraction and spectroscopy on materials under swift heavy ion irradiation.


 In August, Zeiss installed our new Field Emission Scanning Electron Microscope (Gemini 500) in the materials research department. Images of our nanostructures with resolution in the range of 1 nm are possible.

Congratulation to our recent PhDs

2015 May - SHIM in Darmstadt

The conference, which took place in Darmstadt this year, brought together almost 180 scientists from more than 20 countries. During four days the participants discussed recent insights into the complex processes occurring when high-energy ions interact with matter. The program covered basic and applied research including topics such as radiation effects in many different solids, beam-induced material modifications, radiation biology, as well as nanotechnology, atomic physics, and plasma physics with ion beams. The conference was organized by the Materials Research department of GSI.

2015 May - Kurt Schwartz

At the occasion of his 85th birthday, Prof. Kurt Schwartz was honored in recognition of his outstanding scientific work and lifetime achievements in radiation physics.

2015 May - SHIM Poster award

On Wednesday, 20 May 2015, Julian Amani (Univ. Göttingen), Jacob Shamblin (Univ Tennessee), Florian Meinerzhagen (Univ. Duisburg-Essen), and Anne Spende (TU Darmstadt) received awards for best posters presented at the 9th International Symposium on Swift Heavy Ions in Matter, SHIM 2015. The awards sponsored by Pantechnik are endowed with 100 Euro each.

2014 November -- Herzlichen Glückwunsch Katharina

Katharina Kupka (GSI Materialforschung & TU Darmstadt) und Ralf-Arno Tripolt (TU Darmstadt) erhielten den diesjährigen Preis der HGS-HIRe Graduiertenschule für herausragende Leistungen im Rahmen ihrer Promotionsarbeit. Die Auszeichnung wurde während der HGS-HIRe Graduate Days auf Gut Hühnerhof in Gründau durch Prof. H. Büsching verliehen.

Katharina Kupka ist Materialwissenschaftlerin und derzeit in ihrem dritten Promotionsjahr. Sie untersucht Ionenstrahlen induzierte Effekte wie Strukturveränderungen und Strahlenschäden in kohlenstoffbasierten Stripperfolien unter extremen Bestrahlungsbedingungen wie sie künftig bei FAIR erwartet werden.

Wir gratulieren beiden Preisträgern ganz herzlich.

2012 August -- Experiments on interstelar ice

Ices (H2O, CO, CO2, NH3, ..) are omnipresent in space (comets, moons of giant planets, dust grains in dense clouds, the birthplaces of stars) and exposed to cosmic rays, which in turn induce radiolysis (fragmentation of initial molecules, formation of radicals, synthesis of complex, even pre-biotic molecules such as amino acids). We study the specific effects induced by the heavy ion fraction of cosmic rays by infrared absorption spectroscopy (allows to follow molecule destruction and synthesis) and mass spectroscopy of sputtered particles. A first test experiment was successfully conducted at GSI M-branch with two different charge states of Ti irradiation CO2.
