Ablagerungsbildung und ihre Minderung in der Membrandestillation zur Konzentrierung von Meerwasser Fouling and its Mitigation in Membrane Distillation for Seawater Brine Concentration

open access: yesChemie Ingenieur Technik, EarlyView.
Membrandestillation ist ein vielversprechendes Verfahren zur Konzentrierung salzhaltiger Wässer. Kristallisationsfouling und dessen Verminderung mit Additiven wurden in einer Laboranlage bei der Meerwasserkonzentrierung untersucht. Zur Ermittlung der Foulingneigung in einem großen Modul kamen ein Prozessmodell und geochemische Software zum Einsatz ...

Water pathways and ancient lakes: Flowing towards new models to unravel the past

open access: yesThe Depositional Record, EarlyView.
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

open access: yesThe Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Of all shapes and sizes: a theoretical framework for animal‐mediated terrestrial heterogeneity across scales

open access: yesEcography, EarlyView.
Animals redistribute elements throughout their lives by depositing wastes and carcasses. Growing evidence shows that these zoogeochemical processes enhance landscape diversity and heterogeneity worldwide. We provide a descriptive framework for understanding how direct animal depositions (i.e.
