TL;DR: This work suggests that at least prior to mineralization the silk is in the form of a hydrated gel, which significantly changes previous models of the matrix structure and hence hypotheses pertaining to the mechanisms by which mineral formation occurs.

TL;DR: Investigation of different chain lengths and tethering densities of the polymers as well as the interparticle potentials for nanometric versus mesoscopic particles suggests that polymer-induced steric stabilization provides a generic method for separation of SWNTs from mixtures of colloidal species, as demonstrated experimentally.

TL;DR: In this article, the transition from amorphous calcium carbonate (ACC) to calcite in whole larvae and isolated spicules during development has been monitored using X-ray absorption spectroscopy (XAS).

TL;DR: The method opens a new route for utilization of block copolymers as compatibilizers for SWNT, improving the incorporation of de-agglomerated SWNT into target polymeric matrixes.

TL;DR: In this article, the authors compare the organization of the first coordination shells around the calcium ion in biogenic ACC phases from three different sources, and show that although the three biogenic samples have the same chemical composition, which is referred to collectively under the name “amorphous calcium carbonate”, they are structurally different from one another.
