Photo-Fenton inactivation of MS2 bacteriophage at alkaline pH by Fe salts or nm to μm-sized oxides, and the Janus-faced effects of natural organic matter in surface waters
César Pulgarin, Stefanos Giannakis, Giulio Farinelli, Ogadimma Cassandra Oji-Okoro
In this study, MS2 bacteriophage was inactivated by homogeneous and heterogeneous photo-Fenton processes in an alkaline matrix (pH 8) using low concentrations of H2O2 and iron forms (1 mg/L), including Fe(II), Fe(III), and Fe (hydr)oxides. As a reference, ...
Elsevier2024Seasonal phytoplankton and geochemical shifts in the subsurface chlorophyll maximum layer of a dimictic ferruginous lake
Subsurface chlorophyll maxima layers (SCML) are ubiquitous features of stratified aquatic systems. Availability of the micronutrient iron is known to influence marine SCML, but iron has not been explored in detail as a factor in the development of freshwat ...
2022Iron incorporation in synthetic precipitated calcium silicate hydrates
David Lyndon Emsley, Paul Bowen, Brennan James Walder, Jirawan Siramanont
Effect of Fe3+ on the precipitation of synthetic calcium silicate hydrates (C-S-H) under controlled conditions has been evaluated. Using extremely basic either initial calcium nitrate or sodium silicate solutions (pH > 11), incipient formation of ferrihydr ...
2021Both diversity and functional composition affect productivity and water use efficiency in experimental temperate grasslands
Charlotte Grossiord, Margaux Clara Lou Didion-Gency
Many experiments have shown that biodiversity promotes ecosystem functioning and stability and that this relationship varies with resource availability. However, we still have a poor understanding of the underlying physiological and ecological mechanisms d ...
WILEY2021Differentiation of coarse-mode anthropogenic, marine and dust particles in the High Arctic islands of Svalbard
Understanding aerosol–cloud–climate interactions in the Arctic is key to predicting the climate in this rapidly changing region. Whilst many studies have focused on submicrometer aerosol (diameter less than 1 µm), relatively little is known about the super ...
2021Root carbon and nutrient homeostasis determines downy oak sapling survival and recovery from drought
The role of carbon (C) and nutrient uptake, allocation, storage and especially their interactions in survival and recovery of trees under increased frequencies and intensities of drought events is not well understood. A full factorial experiment with four ...
2021Séquestration du CO2: remettre le carbone à sa place
Le climat mondial se réchauffe sous l’influence des émissions de carbone fossile que l’activité humaine injecte dans l’atmosphère. La technologie de captage et de séquestration de CO2, qui permettrait en quelque sorte de le remettre à sa place dans le cyc ...
espazium2020Cycling of zinc and its isotopes across multiple zones of the Southern Ocean: Insights from the Antarctic Circumnavigation Expedition
Zinc (Zn) is an essential micronutrient, playing an important role in several key processes in marine phytoplankton. Here, we present the first high-resolution depth profiles for dissolved Zn and delta Zn-66 from all major zones of the Southern Ocean, coll ...
2020Mixing processes and their ecological implications: From vertical to lateral variability in stratified lakes
Oscar Rodrigo Sepúlveda Steiner
The physical environment of natural waters influences biogeochemical processes to generate specific ecological niches, promoting biophysical interactions. Bacteria and phytoplankton communities can form spatial structures, such as layers and patches. The p ...
