Current Developments in Operando Electron Paramagnetic Resonance Spectroscopy
Get PDFElectron paramagnetic resonance (EPR) spectroscopy is a powerful tool for in situ/operando tracking of catalytic reactions that involve paramagnetic species either as a catalyst (e.g. transition metal ions or defects), reaction intermediates (radicals) or poisoning agents such as coke. This article provides a summary of recent experimental examples and developments in resonator design as well as detection schemes that were carried out in our group. Opportunities for applying this technique are illustrated by examples, including studies of transition metal exchanged zeolites and metal-free zeolites as well as metal oxide catalysts. The inherent limitations of EPR applied at high temperatures are discussed, as well as strategies in reducing or lifting these restrictions are evaluated and ideas for future improvements and methodologies are discussed
Women in Natural Sciences (WiNS) at ETH Zurich Celebrates its 10th Anniversary – A Retrospective and Outlook
Get PDFFor this CHIMIA special issue on the United Nations Sustainable Development Goals (SDGs) and the coincidental 10th anniversary of the association of Women in Natural Sciences (WiNS) at ETH Zurich, there is no better opportunity to share what we have achieved in the last decade. WiNS was originally founded by female PhD students and PostDocs at the Department of Chemistry and Applied Biosciences (D-CHAB) and has expanded to include three additional departments at ETH Zurich. Join us in celebrating our anniversary, reflecting on what we and other associations with the same mission have done to promote gender equality and reduced inequalities for all. We invite you to reflect on what yet has to be done to enact a systemic change towards achieving equal opportunities for all, rather than simply accommodating the female perspective to Switzerland’s predominantly masculine working culture

Get PDFThe formation of collagen, the most abundant protein in mammals, is vital for the integrity of skin, tendons, and tissue in essentially any organ. Excessive collagen formation is, however, characteristic of fibrotic and malignant diseases, which include major global health issues. The diagnosis of abnormal collagen production and deposition is, therefore, critical for disease prognosis and helps guide treatment decisions. Here, we summarize our research on the development of tailored tools for monitoring and targeting excessive collagen crosslinking. We anticipate these tools will provide a deep understanding at the molecular level of collagen formation in normal and disease conditions with applications in imaging and disease treatment
