Quantitative analysis of the crystalline bond lattice of bio-improved soils using micro-computed tomography

The study presents a comprehensive characterization of the fabric of bio-improved soils by introducing an image based quantitative analysis of the crystalline bond lattice, as a means of better understanding and interpreting the observed mechanical respons ...

On the Application of Microbially Induced Calcite Precipitation for Soils: A Multiscale Study

Lyesse Laloui, Dimitrios Terzis

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 ...

Rapid mobilization of noncrystalline U(IV) coupled with FeS oxidation

Rizlan Bernier-Latmani, Malgorzata Alicja Stylo

The reactivity of disordered, noncrystalline U(IV) species remains poorly characterized despite their prevalence in biostimulated sediments. Because of the lack of crystalline structure, noncrystalline U(IV) may be susceptible to oxidative mobilization und ...

Clumped isotope fractionation during phosphoric acid digestion of carbonates at 70°C

Marie Estelle Solange Violay

The application of clumped isotopes (Delta(47)) in carbonate minerals as a sensitive temperature proxy in paleo-environments depends on a well-constrained clumped isotope fractionation for the necessary step of phosphoric acid digestion of the carbonate mi ...

Aragonitic scleractinian corals in the Cretaceous calcitic sea.

Anders Meibom, Jaroslaw Hubert Stolarski, Stéphane Laurent Escrig

Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first e ...

Understanding the nature of atmospheric acid processing of mineral dusts in supplying bioavailable phosphorus to the oceans

Athanasios Nenes

Acidification of airborne dust particles can dramatically increase the amount of bioavailable phosphorus (P) deposited on the surface ocean. Experiments were conducted to simulate atmospheric processes and determine the dissolution behavior of P compounds ...

Functionalized Ionic (Poly)Styrenes and their Application as Catalysts in the Cycloaddition of CO2 to Epoxides

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Felix Daniel Bobbink, Shoubhik Das

Valorization of CO2, an abundant C(1) synthon, into platform chemicals is of growing interest. In this context, a key reaction is the cycloaddition of CO2 to epoxides to form carbonates (CCE). A series of organocatalysts for this reaction, based on imidazo ...

On the Hydro-Mechanical Behaviour of Remoulded and Natural Opalinus Clay Shale

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The geo-energy sector makes use of advanced technologies such as shale gas extraction, CO2 sequestration and nuclear waste geological disposal that rely on the exploitation of shale formations. Due to the great depths involved in these applications and the ...

Morphology, microstructure, crystallography, and chemistry of distinct CaCO3 deposits formed by early recruits of the scleractinian coral Pocillopora damicornis

Anders Meibom, Duncan Thomas Lindsay Alexander, Jaroslaw Hubert Stolarski, Melany Melissa Gilis

Scleractinian corals begin their biomineralization process shortly after larval settlement with the formation of calcium carbonate (CaCO3) structures at the interface between the larval tissues and the substrate. The newly settled larvae exert variable deg ...
