Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Calcite is among the most abundant minerals on earth and plays a central role in many environmental and geochemical processes. Here we used amplitude modulation atomic force microscopy (AFM) operated in a particular regime to visualize single ions close to ...
Freshwater carbonates are interesting archives in palaeoenvironmental reconstructions. However, more studies of those systems are needed to fully understand past environments. In this work the actively-forming travertines of the Alhama-Jaraba thermal syste ...
ature produces biomineral‐based materials with a fascinating set of properties using only a limited number of elements. This set of properties is obtained by closely controlling the structure and local composition of the biominerals. We are far from obtain ...
The hydration of metakaolin composite cements containing quartz, natural limestone and dolomite rock is studied using a multi-method approach and modelling. The study demonstrates that the calcite present in limestone and dolomite rock is very reactive. Co ...
CO2 injection and storage in geological reservoirs is an attractive prospect for mitigating the anthropogenic production of greenhouse gases and global warming. The technology could lead to mineral precipitation and therefore stable storage over geological ...
Species of Haliotis (abalone) show high variety in structure and mineralogy of the shell. One of the European species (Haliotis tuberculata) in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
Two laboratory experiments are used to provide preliminary evidence towards upscaling the microbially induced calcite precipitation (MICP) for soils. Fine sand is packed and subsequently subjected to MICP treatment in 11-liter cylindrical tanks. Different ...
Bio-chemical processes have recently become the core of several studies in the geoengineering field, where the emphasis is placed on new and emerging applications. Microbially Induced Calcite Precipitation has been introduced as an alternative cementation ...
Species of Haliotis ~abalone! show high variety in structure and mineralogy of the shell. One of the European species ~Haliotis tuberculata! in particular has an unusual shell structure in which calcite and aragonite coexist at a microscale with small patc ...
Bacterial strains producing urease can have a major impact on the natural calcite precipitation process if they are supplied with nutrients and urea. In Microbial Induced Calcite Precipitation (MICP) process, the precipitated calcite acts as a cementing ag ...
