Diagenetic isotope exchange in biocalcites for paleoclimate reconstruction
Deyanira Graciela Cisneros Lazaro
The oxygen isotope compositions of fossil biocalcites, such as foraminifera, bivalves, brachiopods, and belemnites have allowed for reconstructions of sea surface and deep ocean temperatures throughout the Phanerozoic and constitute the most important reco ...
EPFL2024Influence of pore-scale heterogeneity on the precipitation patterns in Microbially Induced Calcite Precipitation (MICP)
The principle of tailoring material properties to improve the mechanical behaviour of soils through compaction or cement grouting dates to the 60s. The increasing trends of urbanization worldwide require new solutions for the development of resilient and s ...
EPFL2023First paleoproteome study of fossil fish otoliths and the pristine preservation of the biomineral crystal host
Anders Meibom, Jaroslaw Hubert Stolarski, Jinming Guo
Otoliths are calcium carbonate components of the stato-acoustical organ responsible for hearing and maintenance of the body balance in teleost fish. During their formation, control over, e.g., morphology and carbonate polymorph is influenced by complex ins ...
NATURE PORTFOLIO2023Fine-scale dynamics of calcite precipitation in a large hardwater lake
In hardwater lakes, calcite precipitation is an important yet poorly understood process in the lacustrine carbon cycle, in which catchment-derived alkalinity (Alk) is both transformed and translocated. While the physico-chemical conditions supporting the s ...
ELSEVIER2022Microfluidic-Based Study on the Activation and Evolution of Calcite Bio-Mineralization for Geotechnical Applications
Lyesse Laloui, Dimitrios Terzis, Filippo Miele, Ariadni Elmaloglou
The field of geotechnics is moving fast towards benefiting from new methods and tools to improve the understanding of couplings among complex transport, chemical and biological phenomena. Calcite bio-mineralization, result of bio-grouting, stands out as su ...
2020The impact of calcite impurities in clays containing kaolinite on their reactivity in cement after calcination
Karen Scrivener, Franco Alberto Zunino Sommariva, Emmanuelle Boehm Courjault
The use of supplementary cementitious materials as a partial replacement for Portland cement is the most effective way to reduce the carbon footprint of the concrete industry. Raw clays containing kaolinite (kaolin) are promising substitute materials. In t ...
