Equal abundance of summertime natural and wintertime anthropogenic Arctic organic aerosols
Julia Schmale, Imad El Haddad, Houssni Lamkaddam, Pragati Rai
Aerosols play an important yet uncertain role in modulating the radiation balance of the sensitive Arctic atmosphere. Organic aerosol is one of the most abundant, yet least understood, fractions of the Arctic aerosol mass. Here we use data from eight obser ...
2022Fluorescent aerosols in the Arctic: Seasonality and sources
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Hélène Paule Angot, Margarida Teles Nogueira Rolo
Aerosol-cloud interactions play an important role in regulating the Arctic climate. However, cloud formation processes in the Arctic remain poorly understood and information on aerosol properties in this environment are insufficient, especially during pola ...
2022The influence of the crowding assumptions in biofilm simulations
Vassily Hatzimanikatis, Liliana Angeles Martinez
Author summary In nature, many organisms grow in crowded biofilms that protect against stressful conditions, making their control/eradication a challenge. Modeling these microbial systems is a valuable tool for studying the interactions among cells and exp ...
PUBLIC LIBRARY SCIENCE2021Investigation of Biogenic Passivating Layers on Corroded Iron
This study evaluates mechanisms of biogenic mineral formation induced by bacterial iron reduction for the stabilization of corroded iron. As an example, the Desulfitobacterium hafniense strain TCE1 was employed to treat corroded coupons presenting urban na ...
2020Life cycle assessment integration into energy system models: An application for Power-to-Methane in the EU
François Maréchal, Alexis Laurent
As the EU energy system transitions to low carbon, the technology choices should consider a broader set of criteria. The use of Life Cycle Assessment (LCA) prevents burden shift across life cycle stages or impact categories, while the use of Energy System ...
2020Unexpected large evasion fluxes of carbon dioxide from turbulent streams draining the world’s mountains
Tom Ian Battin, Enrico Bertuzzo, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Pier Luigi Segatto
Inland waters, including streams and rivers, are active components of the global carbon cycle.Despite the large areal extent of the world’s mountains, the role of mountain streams forglobal carbonfluxes remains elusive. Using recent insights from gas excha ...
2019A Reassessment of of the geochemical and isotopic fidelity of biogenic carbonates
Anders Meibom, Jaroslaw Hubert Stolarski, Arthur Adams, Deyanira Graciela Cisneros Lazaro, Jinming Guo, Tarek Axel Vennemann
Oxygen isotope compositions of calcite foraminifera tests are considered to be a robust palaeotemperature proxy at earth-surface conditions, where diffusion is slow. Recrystallization of tests during diagenesis may be optically identified and is often the ...
2019Soluble and Solid Iron Reduction Assays with Desulfitobacterium hafniense
There is a pressing need to develop sustainable and efficient methods to protect and stabilize iron objects. To develop a conservation-restoration method for corroded iron objects, this bio-protocol presents the steps to investigate reductive dissolution o ...
2018Bacterial iron reduction and biogenic mineral formation for the stabilisation of corroded iron objects
Julien Maillard, Arnaud Michel Gelb
Exploiting bacterial metabolism for the stabilisation of corroded iron artefacts is a promising alternative to conventional conservation-restoration methods. Bacterial iron reduction coupled to biogenic mineral formation has been shown to promote the conve ...
2018Use of Bacteria To Stabilize Archaeological Iron
Iron artifacts are common among the findings of archaeological excavations. The corrosion layer formed on these objects requires stabilization after their recovery, without which the destruction of the item due to physicochemical damage is likely. Current ...
