Assessing the precursors and reactions leading to the carcinogenic N-nitrosodimethylamine (NDMA) during drinking water disinfection is a major challenge. Here, we investigate whether changes of C-13/C-12,H-2/H-1, and N-15/N-14 ratios of NDMA give rise to i ...
Mitigation of N-nitrosodimethylamine (NDMA) and other hazardous water disinfection byproducts (DBP) is currently hampered by a limited understanding of DBP formation mechanisms. Because variations of the stable isotope composition of NDMA can potentially r ...
Disinfection processes such as chlorination, chloramination, and ozonation are a crucial measure to provide safe drinking water because they effectively inactivate pathogenic microorganisms. However, these processes can also lead to the formation of harmfu ...
Knowledge of paleo-redox conditions in the Earth's history provides a window into events that shaped the evolution of life on our planet. The role of microbial activity in paleo-redox processes remains unexplored due to the inability to discriminate biotic ...
Assessing the pathways and rates of organic pollutant transformation in the environment is a major challenge due to co-occurring transport and degradation processes. Measuring changes of stable isotope ratios (e.g. C-13/C-12, H-2/H-1, N-15/N-14) in individ ...
Assessment of available water is the basis that allows for sustainable management of the water resource. Special need concerns the assessment of groundwater resources, about which, often little is known. The present study aims to explore the water resource ...
Fractionation of isotopes among distinct molecules or phases is a quantum effect which is often exploited to obtain insights on reaction mechanisms, biochemical, geochemical, and atmospheric phenomena. Accurate evaluation of isotope ratios in atomistic sim ...
The proton double quantum-carbon single quantum correlation experiment has been applied to designed peptides in the solid state in natural isotopic abundance. Analogous to nOe studies in solution, through-space double-quantum connectivities have been explo ...
Laser ablation ionisation time-of-flight mass spectrometry is a versatile technique to obtain highly sensitive measurement of the elements and isotope composition of solid materials. Because of the measurements of nearly all elements in the sample, large i ...
Ti-foils are currently used as a spallation target material to produce radioisotopes for physics research at the ISOLDE facility at CERN. However, radioisotope production rates often decrease over time due to material degradation from high operation temper ...
