Laboratory for Macromolecules and BioimagingLSB
HERCULES school 2019 at SLS
In the week of April 1-5 PSI welcomes 20 PhD students and postdocs taking part in the European HERCULES 2019 school on Neutron and Synchrotron Radiation. They will attend lectures and perform two days of practical courses at several beam lines of the Swiss Light Source.
Lithium ion batteries (LIB) are essential in modern everyday life, with increasing interest in enhancing their performance and lifetime. Secondary particles of Li-rich cathode material were examined with correlated ptychographic X-ray tomography and diffraction microscopy at different stages of cycling to probe the aging mechanism.
Insights into a well-known disease in ageing populations: Abdominal and popliteal aneurysm
Abdominal aortic aneurysm, an enlargement of the abdominal aorta, may lead to rupture and thus acute health issues and death. Scanning X-ray imaging enabled new insights in the nano-structure of calcifications associated with abdonimal and popliteal aneurysm and allowed mapping the distribution of nano- and micro-calcifications as well as of collagen, elastin and myofilament as building blocks of connective tissue across samples from human donors.
Virtual lens improves X-ray microscopy
A method developed by PSI researchers makes X-ray images of materials even better. The researchers took a number of individual images while moving an optical lens. From these, with the help of computer algorithms, they generated one overall image.
Helping chemists to understand degradation and stabilization of catalytic nanoporous gold structures
Catalytic materials are ubiquitously used in industrial processes to perform chemical reactions efficiently and in a sustainable manner. Nanoporous gold (npAu) is a monolithic sponge-like catalyst exhibiting a hierarchical structure with pores and connecting ligaments of typically 10 to 50 nm.
A crystal-clear picture
Fast and accurate data collection for macromolecular crystallography using the JUNGFRAU detector.
Claire Donnelly dissertation research awards
Claire Donnelly, Mesoscopic Systems (ETH Zurich - PSI), was awarded the COMSOL SPS Award in Computational Physics, the Werner Meyer-Ilse Memorial Award, the ETH Medal for an outstanding doctoral thesis, and the American Physical Society Richard L. Greene Dissertation Award.
First serial femtosecond crystallography (SFX) pilot user experiment at SwissFEL
On the 7th to 12th of August 2018, a collaborative group of scientists from the Paul Scherrer Institute and members of the LeadXpro and Heptares pharmaceutical companies led by Karol Nass (PSI macromolecular crystallography MX-SLS group) performed the first serial femtosecond crystallography (SFX) pilot user experiment at the SwissFEL X-ray free electron laser (XFEL).
Rhine-Knee Regiomeeting 2018
Since it was first established in 1987, the annual Regio-Meeting has been instrumental in facilitating interactions in the structural biology community in southwestern Germany, the eastern region of France and an expanding area of Switzerland. It is set as an informal event to foster young scientists to discuss their research results in an international context. The 2018 edition will take place in the heart of Switzerland in Emmetten from September 26 to 28, 2018. Registration and abstract submission deadline: September 7, 2018.
