摘要
We observed spontaneous formation of very complex structures, measurable on the centimeter and millimeter scales, in a simple dual-component inorganic chemical system. The diffusion, convection, and chemical reactions self-organize in space and time and produce domes, multi-arms, or more complex structures with different spatial organization depending on the concentration of reagents in the aqueous environment into which the 'seed' is immersed.
