The influence of environmental drivers on the enrichment of organic carbon in the sea surface microlayer and in submicron aerosol particles – measurements from the Atlantic Ocean

Autor: Manuela van Pinxteren, Stefan Barthel, Khanneh Wadinga Fomba, Konrad Müller, Wolf von Tümpling, Hartmut Herrmann

Publikováno v: Elementa: Science of the Anthropocene, Vol 5 (2017)

The export of organic matter from ocean to atmosphere represents a substantial carbon flux in the Earth system, yet the impact of environmental drivers on this transfer is not fully understood. This work presents dissolved and particulate organic car

Do new sea spray aerosol source functions improve the results of a regional aerosol model?

Autor: Stefan Barthel, Ina Tegen, Ralf Wolke

Publikováno v: Atmospheric Environment. 198:265-278

Sea spray aerosol particle is a dominating part of the global aerosol mass load of natural origin. Thus, it strongly influences the atmospheric radiation balance and cloud properties especially over the oceans. Uncertainties of the estimated climate

Publikováno v: Frontiers in Microbiology, Vol 15 (2024)

Nature utilizes three distinct pathways to synthesize the essential enzyme cofactor heme. The coproporphyrin III-dependent pathway, predominantly present in Bacillaceae, employs an oxygen-dependent coproporphyrinogen III oxidase (CgoX) that converts

Publikováno v: Physical Review B. 96

The characteristics of the cooperative Mott-Peierls metal-insulator transition (MIT) of ${\mathrm{VO}}_{2}$ can be altered by employing epitaxial strain. While the most commonly used substrate for this purpose is isostructural rutile ${\mathrm{TiO}}_
