Fine-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 ...
ELSEVIER2022Additives: Their Influence on the Humidity- and Pressure-Induced Crystallization of Amorphous CaCO3
Esther Amstad, Camelia Borca, Huachuan Du, Mathias Steinacher, Alan Böhlen, Clémence Courrégelongue
Nature possesses a unique control over the formation of CaCO3 crystals that imparts fascinating mechanical properties to many CaCO3-based biomaterials. This high level of control is, at least in part, achieved through the use of certain soluble additives t ...
AMER CHEMICAL SOC2020Direct currents stimulate carbonate mineralization for soil improvement under various chemical conditions
Lyesse Laloui, Dimitrios Terzis, Patrick Gabriel Yihsiu-Ming Hicher
The present study integrates direct electric currents into traditional calcium carbonate mineralization to investigate electrochemical interactions and the subsequent crystalline growth of CaCO3 bonds in sand. A specific line of focus refers to the effect ...
2020Prediction and experimental evaluation of soil-water retention behavior of skeletal calcareous soils
Lyesse Laloui, Saeed Kouzegaran
Skeletal calcareous soils refer to soils consisting of skeletal remains of marine organisms. Although calcareous deposits are prevalent along coastal plains throughout the world, there is no study which investigates their behavior in unsaturated conditions ...
2020Water: its influence on the formation and crystallization of amorphous calcium carbonate
Nature produces CaCO3-based materials that display fascinating mechanical properties. These properties are a result of the exquisite control over the formation of CaCO3 crystals that nature possesses. Such a high level of control is likely achieved, at lea ...
EPFL2019Cell-free soil bio-cementation with strength, dilatancy and fabric characterization
Lyesse Laloui, Dimitrios Terzis
A multi-disciplinary approach is adopted in the present work towards investigating bio-cemented geo-materials which extends from sample preparation, to microstructural inspection and mechanical behaviour characterization. We suggest a new way to induce “ce ...
2019Water: How does it influence the CaCO3 formation?
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 ...
