A modern scleractinian coral with a two-component calcite–aragonite skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. All modern scleractinian corals are thought to produce skeletons exclusively of the calcium-carbonate polymorph aragonite. ...

Direct 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 ...

Ammonium is the preferred source of nitrogen for planktonic foraminifer and their dinoflagellate symbionts

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

The symbiotic planktonic foraminiferaOrbulina universainhabits open ocean oligotrophic ecosystems where dissolved nutrients are scarce and often limit biological productivity. It has previously been proposed thatO. universameets its nitrogen (N) requiremen ...

Benefits and drawbacks of applied direct currents for soil improvement via carbonate mineralization

Lyesse Laloui, Dimitrios Terzis, Patrick Gabriel Yihsiu-Ming Hicher

The study presented herein adopts a new vision of the processes involved in carbonate mineralization induced by MICP from an electrochemical and crystal growth perspective. More precisely a specific line of focus refers to the species involved in the bio-c ...

Global radiation in a rare biosphere soil diatom

Tyler Joe Kohler

Soil micro-organisms drive the global carbon and nutrient cycles that underlie essential ecosystem functions. Yet, we are only beginning to grasp the drivers of terrestrial microbial diversity and biogeography, which presents a substantial barrier to under ...

Synthesis and characterizations of biocompatible polymers and carbon nanotubes-based hybrids for biomedical applications

Lakshmi Devi Chakkarapani

The outstanding physico-chemical properties of carbon nanotubes (CNTs) applied to rectify the problems in bone tissue engineering through enhancing cell proliferation, adhesion and viability, which lead to the improvement in bone replacement, growth and he ...

Investigation of Biogenic Passivating Layers on Corroded Iron

Julien Maillard

This study evaluates mechanisms of biogenic mineral formation induced by bacterial iron reduction for the stabilization of corroded iron. As an example, the Desulfitobacterium hafniense strain TCE1 was employed to treat corroded coupons presenting urban na ...

Microfluidic-Based Study on the Activation and Evolution of Calcite Bio-Mineralization for Geotechnical Applications

Lyesse Laloui, Dimitrios Terzis, Ariadni Elmaloglou, Filippo Miele

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 ...

Structural description of surfaces and interfaces in biominerals by DNP SENS

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

Biological mineralized tissues are hybrid materials with complex hierarchical architecture composed of biominerals often embedded in an organic matrix. The atomic-scale comprehension of surfaces and organo-mineral interfaces of these biominerals is of para ...

Water: How does it influence the CaCO3 formation?

Esther Amstad, Huachuan Du

Nature 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 obtai ...
