Importance of eDNA taphonomy and sediment provenance for robust ecological inference: Insights from interfacial geochemistry
Autor: K. K. Sand, S. Jelavić, K. H. Kjær, A. Prohaska
Publikováno v: Environmental DNA, Vol 6, Iss 2, Pp n/a-n/a (2024)
Abstract Retrieval of modern and ancient environmental DNA (eDNA) from sediments has revolutionized our ability to study past and present ecosystems. Little emphasis has been placed, however, on the fundamentals of the DNA–sediment associations in

The mechanisms of crystal growth inhibition by organic and inorganic inhibitors
Autor: S. Dobberschütz, M. R. Nielsen, K. K. Sand, R. Civioc, N. Bovet, S. L. S. Stipp, M. P. Andersson
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-6 (2018)
Although trace compounds are known to inhibit crystal growth, the mechanisms by which they do so are unclear. Here, the authors use a microkinetic model to study the mechanisms of several inhibitors of calcite growth, finding that the processes are q

Quantifying the free energy landscape between polymers and minerals
Autor: K. K. Sand, R. W. Friddle, J. J. DeYoreo
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-5 (2017)
Abstract Higher organisms as well as medical and technological materials exploit mineral-polymer interactions, however, mechanistic understanding of these interactions is poorly constrained. Dynamic force spectroscopy can probe the free energy landsc

The absence of organic compounds from Precambrian iron formations (IF) challenges the hypothesis of the biogenic origin of IF. Here we address the fate of adsorbed organic compounds during transformation from ferrihydrite to hematite. We determined t

The production of novel composite materials, assembled using biomimetic polymers known as peptoids (N-substituted glycines) to nucleate CaCO3, can open new pathways for advanced material design. However, a better understanding of the heterogeneous Ca

Publikováno v: Chemical Communications. 53:12700-12703
We measured the binding energy and bonding parameters between model nucleotide functional groups and model clay mineral surfaces in solutions of acidic pH. We demonstrate that basal surfaces of clay minerals interact most strongly with nucleobases an
