Invited for this month's cover is the group of Marcus Herbig from the TU Bergakademie in Freiberg. The cover picture shows the reaction of CO with a silyl derivative of the biogenic amine ethanolamine. The role of CO as a contributor to climate change makes "carbon capture" a desirable goal. However, in addition to simply capture CO, aminosilanes form silylcarbamates, which represent starting materials for a variety of crucial chemicals. Thus, the entrapped CO represents a useful C building block. The ESF-funded Junior Research Group CO-Sil at the TU Bergakademie Freiberg (represented by their Logo and location) pursues that kind of goals. CO-Sil studies these key reactions of CO insertion in depth by syntheses, quantum chemical calculations and calorimetric experiments. CO brought to the ground by our method shall be feedstock for various branches in chemistry. Read the full text of their Full Paper at 10.1002/open.201900269.

Managing mine water in the best possible way is of great importance and depends on various factors like environmental protection, regulatory compliance and human health. To understand the complex chemical and hydrodynamic processes within the mine pool, it is critical to establish effective practices and management strategies. This study focuses on the characterisation of hydrodynamic processes affecting flooded underground mines, emphasising the importance of density stratification.

Streptofilum capillatum was recently described and immediately caught scientific attention, because it forms a phylogenetically deep branch in the streptophytes and is characterised by a unique cell coverage composed of piliform scales. Its phylogenetic position and taxonomic rank are still controversial discussed. In the present study, we isolated further strains of Streptofilum from biocrusts in sand dunes and Arctic tundra soil.

This study focuses on the effect of pre-deformation on hydrogen diffusion and hydrogen embrittlement of the high alloy austenitic TRIP steel X3CrMnNiMo17-8-4. Different cold-rolled steel sheets with thicknesses of ≤400 µm were electrochemically charged on both sides in 0.1 M sodium hydroxide with hydrogen for two weeks.

While extreme events have been a focus of research for several decades, often centered around the causes and impacts of meteorological and climatological events, the term has expanded into a range of other disciplines, exploring a wide variety of associated topics. Analytical tools and definitions have hereby posed a challenge that has been addressed in different ways. Drawing from a broad body of research on extreme events, this review takes into account the often complex and cascading nature of extreme events in order to provide a large-scale overview of the main themes, discussions and trends of extreme event research.
