“…The last term here is approximately constant, so that any temporal oscillations in c will be reflected as oscillations in S too [51]. Figure 4 depicts the evolution of the measured rate of change of the surface area of the solid membrane, as well as the pressure inside the pellet, for a range of concentrations of the silicate solution.…”

Concentration cycles are important for bonding of basic molecular building components at the emergence of life. We demonstrate that oscillations occur intrinsically in precipitation reactions when coupled with fluid mechanics in self-assembled precipitate membranes, such as at submarine hydrothermal vents. We show that, moreover, the flow of ions across one pore in such a prebiotic membrane is larger than that across one ion channel in a modern biological cell membrane, suggesting that proto-biological processes could be sustained by osmotic flow in a less efficient prebiotic environment. Oscillations in nanoreactors at hydrothermal vents may be just right for these warm little pores to be the cradle of life.

“…In chemical gardens the motors first selfconstruct spontaneously, and then they may move in many different modes. Examples of the motion include linear translation, rotation [28], periodic rupturing [17,34], periodic buoyancy oscillations, periodic waving or stretching of the entire structure, and periodic ejection of complex tubes [29].…”

Self-organizing precipitation processes, such as chemical gardens forming biomimetic micro- and nanotubular forms, have the potential to show us new fundamental science to explore, quantify, and understand nonequilibrium physicochemical systems, and shed light on the conditions for life's emergence. The physics and chemistry of these phenomena, due to the assembly of material architectures under a flux of ions, and their exploitation in applications, have recently been termed chemobrionics. Advances in understanding in this area require a combination of expertise in physics, chemistry, mathematical modeling, biology, and nanoengineering, as well as in complex systems and nonlinear and materials sciences, giving rise to this new synergistic discipline of chemobrionics.

“…6 This chemical garden phenomenon has been discovered to occur in nature as hydrothermal vents or chimneys [7][8][9][10] and rusts on metals. 11,12 Scientists are now focusing on the formation mechanism, 13 the growth behavior, 14 periodic membrane rupture, 15 surface instabilities 16 or even pattern formation 17,18 and the dynamics in thin solution layer. 19,20 The fascination with chemical gardens has not stopped within the Earth's ground gravity.…”
