Silicic Acid-Mediated Formation of Tannic Acid Nanocoatings [PDF]

Langmuir, 2019
Tannic acid (TA) adheres to a broad variety of different materials and forms versatile surface coatings for technical and biological applications. In mild alkaline conditions, autoxidation processes occur and a firm monolayer is formed. Up to now, thicker coatings are obtained in only a cross-linked multilayer fashion.

Differences in Prokaryotic Community Composition Between Two Climatically Contrasting Years in an Arctic Fjord Ecosystem. [PDF]

Environ Microbiol Rep
Seasonal dynamics of prokaryotic communities in Kongsfjorden were driven by contrasting hydrographic conditions in 2019 and 2020. Atlantification enhanced prokaryotic diversity and interactions in 2019, while sea ice and glacial runoff in 2020 reduced surface diversity and network complexity, underscoring Arctic prokaryotic sensitivity to environmental
