title: Simple solution routes for targeted carbonate phases and intricate carbonate and silicate morphologies.
abstract: This work deals with the preparation of ceramic phases similar to those encountered in natural biocomposites through relatively fast and low-cost aqueous routes and various simple reactants and additives such as urea, commercial gelatin and hexamethyldiamine. In addition to the crystallographic (or amorphous) character of targeted phases (calcite, vaterite, aragonite, silica and silicates) particle morphology is also of interest and among others, we have obtained fractions of particles in the form of nanofibrilar calcite networks, calcium silicate doughnuts and Gordian knots, and diatom-like perforated silica cylinders.
