Numerous types of reaction-precipitation systems involve the growth of tubular structures similar to those formed in "silica gardens". As a model case for this phenomenon, we investigate the rapid growth of hollow tubes in the reaction between sodium silicate and cupric sulfate. The latter solution is injected hydrodynamically at constant flow rates of 1-20 mL h(-1) into a large reservoir of waterglass. In this study, the growth is templated and guided by single, buoyant gas bubbles. The… Expand
Tubular precipitation structures: materials synthesis under non-equilibrium conditions
TLDR
Recent advances in inorganic precipitation reactions, known to self-organize a variety of macroscopic structures, including hollow tubes, are discussed with an emphasis on experiments similar to ‘silica gardens’. Expand
Synthesis of Inorganic Tubes under Actively Controlled Growth Velocities and Injection Rates
We describe an experiment that establishes control over the growth velocities of macroscopic tubes in the reaction between a polymerizable inorganic anion and a nonalkali metal ion. Our approach isExpand
Luminescent tubular precipitation structures from reactant-loaded pellets
Abstract Using reaction conditions far from equilibrium, we are able to produce hollow tubes formed from reactant-loaded pellets. The latter pellets are composed of zinc sulfate and phosphorescentExpand
From hydrodynamic plumes to chemical gardens: the concentration-dependent onset of tube formation.
TLDR
The experiments reveal a distinct, concentration-dependent transition from convective plumes of reaction-induced, colloidal particles to mechanically connected, hollow tubes, which are similar to that of laminar starting plumes in nonreactive systems. Expand
Bubble-templated and flow-controlled synthesis of macroscopic silica tubes supporting zinc oxide nanostructures.
TLDR
The synthesis of similar tubes using a flow injection method with gas bubbles as directional guides and templates is presented, consisting of silica-supported zinc oxide nanostructures and show interesting luminescence and photocatalytic properties. Expand
Tube Formation in Reverse Silica Gardens
The flow injection of sodium silicate solution into a large reservoir of lighter cupric sulfate solution creates single, downward growing precipitation tubes. These hollow structures have diametersExpand
Spatially resolved analysis of calcium–silica tubes in reverse chemical gardens
Abstract Reverse chemical gardens consist of hollow tubular structures that form in a downward direction from a mechanically held silicate crystal immersed in a metal salt solution. As a model caseExpand
Osmotic contribution to the flow-driven tube formation of copper-phosphate and copper-silicate chemical gardens.
TLDR
It is shown that the ratio of the volume increase rate to that of pumping is constant independent of the chemical composition, and it is found that osmosis significantly contributes to the tube growth. Expand
The dynamics of open precipitation tubes.
TLDR
Measurements of the radius, length, and internal pressure, as functions of time and flow rate, for precipitation tubes growing in chemical gardens are reported and models for how single tubes grow and also for how multiple tubes interact with each other are developed. Expand
Compositional analysis of copper-silica precipitation tubes.
TLDR
This work investigates the structure and elemental composition of hollow tubular structures that form from salt crystals seeded into silicate solution in silica gardens in the context of a recently developed experimental model that allows quantitative analyses based on predetermined reactant concentrations and flow rates.

TLDR
This work reports a self-organized periodic templating mechanism producing tubular structures electrochemically in iron-ammonium-sulfate solutions; iron oxides precipitate on the surface of bubbles that linger at the tube rim and then detach, leaving behind a ring of material. Expand

TLDR
Two distinct growth regimes of hollow silica fibers formed by hydrodynamic injection of cupric sulfate into silicate solution are reported, applicable to the understanding of chemical gardens, promise a wealth of nonlinear phenomena, and offer possible applications in microfluidics. Expand

Stalactite growth as a free-boundary problem: a geometric law and its platonic ideal.
TLDR
The interplay of thin-film fluid dynamics, calcium carbonate chemistry, and CO2 transport in the cave is considered to show that stalactites evolve according to a novel local geometric growth law which exhibits extreme amplification at the tip as a consequence of the locally-varying fluid layer thickness.

TLDR
