Abstract
The generation of chemobrionic architectures through slow injection of aqueous silicate solution in gaseous TiCl4 is demonstrated. The tubes were characterized by XRD, SEM and wet chemistry control experiments, and their mechanism of formation was unraveled. These structures serve as laboratory models for calthemites or soda straws.
