Multicone Diamond Waveguides for Nanoscale Quantum Sensing
(2023)Nano LettersThe long-lived electronic spin of the nitrogen-vacancy (NV) center in diamonds is a promising quantum sensor for detecting nanoscopic magnetic and electric fields in various environments. However, the poor signal-to-noise ratio (SNR) of prevalent optical spin-readout techniques presents a critical challenge in improving measurement sensitivity. Here, we address this limitation by coupling individual NVs to optimized diamond nanopillars, ...Journal Article -

Robustness of Threshold Collision-Induced Dissociation Simulations for Bond Dissociation Energies
(2024)The Journal of Physical Chemistry AThe threshold collision-induced dissociation (T-CID) method is the workhorse for gas-phase bond dissociation energy (BDE) measurements. However, T-CID does not measure BDEs directly; instead, BDEs are obtained by fitting simulated data to the experimental data. We previously observed several large discrepancies between the computed and experimental BDEs. To analyze the reliability of the experimental values, we previously reported a study ...Journal Article -
Nitrogen availability and plant functional composition modify biodiversity‐multifunctionality relationships
(2024)Ecology LettersBiodiversity typically increases multiple ecosystem functions simultaneously (multifunctionality) but variation in the strength and direction of biodiversity effects between studies suggests context dependency. To determine how different factors modulate the diversity effect on multifunctionality, we established a large grassland experiment manipulating plant species richness, resource addition, functional composition (exploitative vs. ...Journal Article -
Endothelial damage inhibitor preserves the integrity of venous endothelial cells from patients undergoing coronary bypass surgery
(2023)European Journal of Cardio-Thoracic SurgeryObjectives: Despite the success of coronary artery bypass graft (CABG) surgery using autologous saphenous vein grafts (SVGs), nearly 50% of patients experience vein graft disease within 10 years of surgery. One contributing factor to early vein graft disease is endothelial damage during short-term storage of SVGs in inappropriate solutions. Our aim was to evaluate the effects of a novel endothelial damage inhibitor (EDI) solution, DuraGraft®, ...Journal Article -
Enzyme kinetics inform about mechanistic changes in tea litter decomposition across gradients in land-use intensity in Central German grasslands
(2022)Science of The Total EnvironmentGrassland ecosystems provide important ecosystem services such as nutrient cycling and primary production that are affected by land-use intensity. To assess the effects of land-use intensity, operational and sensitive ecological indicators that integrate effects of grassland management on ecosystem processes such as organic matter turnover are needed. Here, we investigated the suitability of measuring the mass loss of standardized tea ...Journal Article -
A new paradigm for structural characterization, including rotational measurements at a single site.
(2023)Bulletin of the Seismological Society of AmericaIn this article, we demonstrate that a single station can be used to measure the dynamic properties of a structure. The station includes a collocated accelerometer and rotational sensor, hence, can record both three‐component translation and three‐component rotation and is referred to as the 6C‐station within this study. The key advantage of this approach is to provide a fast and simple path to a comprehensive structural health monitoring ...Journal Article -
Unique corrosion behavior of an archaeological Roman iron ring: microchemical characterization and thermodynamic considerations
(2024)Corrosion ScienceThe corrosion mechanisms of a Roman iron bezel ring were investigated by in-depth characterization of its uncommon corrosion pattern and thermodynamic modelling. A silver foil and altered glass remnants were identified, covered with thick strata of magnetite and goethite. Underneath it, was a multi-millimetric cavity, filled with spheroidal magnetite or magnetite/goethite nodules in a siderite matrix. The bottom of the preserved object ...Journal Article -
Cyclopentadienone Iron Complex-Catalyzed Hydrogenation of Ketones: The Influence of the Charge-Tag on Catalytic Performance
(2024)OrganometallicsThe reason for the discrepancy in reaction rate in hydrogenation reactions using cyclopentadienone iron complexes as catalysts, depending on the absence or presence of a negative charge-tag (sulfonate or phosphonate), was investigated experimentally. Based on NMR and kinetic experiments, the direct binding of the charge-tag to the active site of the catalyst and electric field effects influencing transition state energies could be excluded. ...Journal Article -
Pangenome-genotyped structural variation improves molecular phenotype mapping in cattle
(2024)Genome ResearchExpression and splicing quantitative trait loci (e/sQTL) are large contributors to phenotypic variability. Achieving sufficient statistical power for e/sQTL mapping requires large cohorts with both genotypes and molecular phenotypes, and so, the genomic variation is often called from short-read alignments, which are unable to comprehensively resolve structural variation. Here we build a pangenome from 16 HiFi haplotype-resolved cattle ...Journal Article
