Article Synopsis
- The study explores how complex solid patterns form in chemical gardens, specifically using microfluidic devices to create Ni(OH) precipitate membranes.
- Researchers identified various light-scattering patterns like disorganized spots and parallel bands, which change based on flow rates.
- The formation of these bands is linked to the aggregation of nanoparticles moving along the membrane, influenced by particle concentration and the mechanics of fluid flow.
Chemical gardens are macroscopic structures that form when a salt seed is submerged in an alkaline solution. Their thin precipitate membranes separate the reactant partners and slow down the approach toward equilibrium. During this stage, a gradual thickening occurs, which is driven by steep cross-membrane gradients and governed by selective ion transport.
