Quantification of the ferric/ferrous iron ratio in silicates by scanning transmission X-ray microscopy at the Fe L2,3 edges

Franck Bourdelle, +7 more
- 04 Jun 2013 - 
TL;DR: In this article, an analytical procedure to quantify the Fe3+/ΣFe ratio in silicates using Fe L2,3-edge X-ray absorption near edge structure (XANES) spectra obtained by scanning transmission Xray microscopy (STXM) is presented.

Nanometer-scale characterization of exceptionally preserved bacterial fossils in Paleocene phosphorites from Ouled Abdoun (Morocco).

Julie Cosmidis, +6 more
- 01 Mar 2013 - 
TL;DR: This study shows that ancient phosphorites can contain fossil biological subcellular structures as fine as a bacterial periplasm and demonstrates that while morphological information provided by SEM analyses is valuable, the use of additional nanoscale analyses is a powerful approach to help inferring the biogenicity of biomorphs found in phosphorite.

A phylogeny reconstruction of the Dendrophylliidae (Cnidaria, Scleractinia) based on molecular and micromorphological criteria, and its ecological implications

Roberto Arrigoni, +10 more
- 01 Nov 2014 - 
TL;DR: A robust molecular phylogeny reconstruction based on two mitochondrial markers (COI and the intergenic spacer between COI and 16S) and one nuclear (rDNA) is used as basis to compare micromorphogical and microstructural character states within the Dendrophylliidae.

Cyanobacterial calcification in modern microbialites at the submicrometer scale

Estelle Couradeau, +6 more
- 01 Aug 2013 - 
TL;DR: In this paper, the initial stages of fossilization of cyanobacterial cells in modern microbialites from Lake Alchichica (Mexico), a Mg-rich hyperalkaline crater lake (pH 8.9) hosting currently growing stromatolites composed of aragonite [CaCO 3 ] and hydromagnesite [Mg 5 (CO 3 )4(OH) 2 · 4(H 2 O)].

Photosymbiosis and the expansion of shallow-water corals

Katarzyna Frankowiak, +7 more
- 01 Nov 2016 - 
TL;DR: It is shown that a suite of exceptionally preserved coral skeletons from Antalya (Turkey) have microstructures, carbonate 13C/12C and 18O/16O, and intracrystalline skeletal organic matter 15N/14N all indicating symbiosis, which suggests coral-dinoflagellate symbiosis was likely a key driver in the evolution and expansion of shallow-water scleractinians.

Nature’s hierarchical materials

Peter Fratzl, +1 more
- 01 Nov 2007 - 
TL;DR: In this paper, the basic principles involved in designing hierarchical biological materials, such as cellular and composite architectures, adapative growth and as well as remodeling, are discussed, and examples that are found to utilize these strategies include wood, bone, tendon, and glass sponges.

Mesocrystals: Inorganic superstructures made by highly parallel crystallization and controlled alignment

Helmut Cölfen, +1 more
- 05 Sep 2005 - 
TL;DR: Mesocrystals are exiting examples of nonclassical crystallization, which does not proceed through ion-by-ion attachment, but by a modular nanobuilding-block route, which makes crystallization more independent of ion products or molecular solubility, it occurs without pH or osmotic pressure changes, and opens new strategies for crystal morphogenesis.
