Chemical gardens are complex, often macroscopic, structures formed by precipitation
reactions. Their thin walls compartmentalize the system and adjust in size and shape if the …

Precipitation of calcium carbonate in bulk solutions is well known to result in a bell-shaped
or bimodal particle size distribution. However, it is unclear how the distribution behaves if …

The dynamics of A+ B→ C fronts is analyzed theoretically in the presence of passive
advection when A is injected radially into B at a constant inlet flow rate Q. We compute the …

In many geological systems, the porosity of rock or soil may evolve during mineral
precipitation, a process that controls fluid transport properties. Here, we investigate the use …

Inorganic precipitate membranes play an important role in chemobrionics and origin of life
research. They can involve a range of catalytic materials, affect crystal habits, and show …

We describe and study the formation of confined chemical garden patterns. At low flow rates
of injection of cobalt chloride solution into a Hele-Shaw cell filled with sodium silicate, the …

In this study, we experimentally investigate fluid–fluid displacement in a Hele–Shaw cell
where the two fluids react, upon mixing, to form solid precipitates. Under the conditions of …

Thin-walled tubes that classically form when metal salts react with sodium silicate solution
are known as chemical gardens. They share similarities with the porous, catalytic materials …

We report the discovery of novel regimes of calcium carbonate dissolution in micron-scale
confined spaces through microfluidic experiments. In the experiments, hydrochloric acid is …

The effects of the $ A+ B\rightarrow C $ chemical reaction on miscible viscous fingering in a
radial source flow are analysed using linear stability theory and numerical simulations. This …
