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 Inc2017An 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 ...
2014Aluminium 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 ...
