Measuring coral calcification under ocean acidification: methodological considerations for the 45Ca-uptake and total alkalinity anomaly technique
Thomas Krüger, Maoz Fine, Stéphanie Kéren Cohen
As the oceans become less alkaline due to rising CO2 levels, deleterious consequences are expected for calcifying corals. Predicting how coral calcification will be affected by on-going ocean acidification (OA) requires an accurate assessment of CaCO3 depo ...
Peerj Inc2017Ligand and Metal Based Multielectron Redox Chemistry of Cobalt Supported by Tetradentate Schiff Bases
Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez
We have investigated the influence of bound cations on the reduction of cobalt complexes of redox active ligands and explored the reactivity of reduced species with CO2. The one electron reduction of [CoII(Rsalophen)] with alkali metals (M = Li, Na, K) lea ...
2017Short-term effects of biochar on grapevine fine root dynamics and arbuscular mycorrhizae production
Application of biochar to the soil is globally recognised as a means to improve soil structure and fertility, increase carbon sequestration, enhance crop production and mitigate climate change. However, although the fine root system is fundamental for plan ...
Elsevier2017An Alien Divalent Ion Reveals a Major Role for Ca2+ Buffering in Controlling Slow Transmitter Release
Ralf Schneggenburger, Daniel Keller, Olexiy Kochubey, Zsolt Norbert Babai
Ca2+-dependent transmitter release occurs in a fast and in a slow phase, but the differential roles of Ca2+ buffers and Ca2+ sensors in shaping release kinetics are still controversial. Replacing extracellular Ca2+ by Sr2+ causes decreased fast release but ...
2014Control of groundwater pH during bioremediation: Improvement and validation of a geochemical model to assess the buffering potential of ground silicate minerals
David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix
Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. The use of ground silicate minerals mixed with groundwater is an appealing buffering strategy as silicate minerals may act as long-term s ...
Elsevier2014Aluminium and alkali uptake in calcium silicate hydrates (C-S-H)
Calcium silicate hydrate (C-S-H) is the main hydrate phase in Portland cements. Its composition
varies depending on the Ca/Si ratio and on the presence of other ions such as aluminium (called CA-
S-H) or alkalis.
This thesis aimed to study the compositi ...
EPFL2014Using Silicate Mineral Particles for pH Control during in situ Bioremediation of Chlorinated Ethene Source Zones
Soil and groundwater pollution by chlorinated solvents such as tricholorethene (TCE) and tetrachloroethene (PCE) is a frequent problem in the industrialized world. Chlorinated solvents, characterized by a low solubility and a density greater than water, fo ...
