Key parameters of volcanic tuffs used as building stone: a statistical approach
(
- Environmental Earth Sciences
, 2021-12-08)
Volcanic tuffs naturally show a strong heterogeneity in their petrography and petrophysical properties. The arrangement of the components in tuffs can create a very wide spectrum of porosities and fabrics, which in turn ...
The soft X‐ray and XUV split‐and‐delay unit at beamlines FL23/24 at FLASH2
(
- Journal of Synchrotron Radiation
, 2023-02-15)
A split‐and‐delay unit for the extreme ultraviolet and soft X‐ray spectral regions has been built which enables time‐resolved experiments at beamlines FL23 and FL24 at the Free‐electron LASer in Hamburg (FLASH). Geometric ...

Young magmatism and Si‐rich melts on Mars as documented in the enriched gabbroic shergottite NWA 6963
(
- Meteoritics & Planetary Science
, 2022-10-17)
Enriched shergottites contain interstitial Si‐rich mesostasis; however, it is unclear whether such mesostasis is formed by impact or magmatic processes. We use laser ablation multicollector inductively coupled plasma mass ...
Bioavailable DOC: reactive nutrient ratios control heterotrophic nutrient assimilation—An experimental proof of the macronutrient-access hypothesis
(
- Biogeochemistry
, 2021-06-08)
We investigate the "macronutrient-access hypothesis", which states that the balance between stoichiometric macronutrient demand and accessible macronutrients controls nutrient assimilation by aquatic heterotrophs. Within ...
Systematic Across‐Arc Variations of Molybdenum Isotopes in a Fluid‐Dominated Subduction Zone System

Riparian Microtopography Affects Event‐Driven Stream DOC Concentrations and DOM Quality in a Forested Headwater Catchment
(
- Journal of Geophysical Research: Biogeosciences
, 2022-12-21)
The transport of dissolved organic carbon (DOC) from the soils to inland waters plays an important role in the global carbon cycle. Widespread increases in DOC concentrations have been observed in surface waters over the ...

Extending MIEZE spectroscopy towards thermal wavelengths
(
- Journal of Applied Crystallography
, 2022-10-27)
A modulation of intensity with zero effort (MIEZE) setup is proposed for high‐resolution neutron spectroscopy at momentum transfers up to 3 Å<sup>−1</sup>, energy transfers up to 20 meV and an energy resolution in the ...
