Mixed-valent iron [Fe (II)-Fe (III)] minerals such as magnetite and green rust have received a
significant amount of attention over recent decades, especially in the environmental …

Reduction–oxidation (redox) reactions occur during burial because sediments contain
reactive mixtures of oxidised and reduced components. Diagenetic chemical reactions …

Microbes play key geoactive roles in the biosphere, particularly in the areas of element
biotransformations and biogeochemical cycling, metal and mineral transformations …

Biodeposition of minerals is a widespread phenomenon in the biological world and is
mediated by bacteria, fungi, protists, and plants. Calcium carbonate is one of those minerals …

Biomineralization refers to the processes by which organisms form minerals. The control
exerted by many organisms over mineral formation distinguishes these processes from …

Magnetotactic bacteria were discovered almost 30 years ago, and for many years and many
different reasons, the number of researchers working in this field was few and progress was …

New theoretical curves relating the hysteresis parameters Mrs/Ms and Hcr/Hc for single‐
domain (SD), superparamagnetic (SP), pseudo‐single‐domain (PSD), and multidomain …

Biomineralization is a known natural phenomenon associated with a wide range of bacterial
species. Bacterial-induced calcium carbonate precipitation by marine isolates was …

Biomimetic mineralization is a powerful approach for the synthesis of advanced materials
with complex shape, hierarchical organization and controlled size, shape and polymorph …

Nanoparticles are discrete nanometer (10-9 m)-scale assemblies of atoms. Thus, they have
dimensions between those characteristic of ions (10-10 m) and those of macroscopic …
