In order to model ion transport across protocell membranes in Hadean hydrothermal vents, we consider both theoretically and experimentally the planar growth of a precipitate membrane formed at interface between two parallel fluid streams two-dimensional microfluidic reactor. The rate is found be proportional square root time, which characteristic diffusive transport. However, dependence on concentrations hydroxide metal ions approximately linear quadratic, respectively. We show that such...
Abstract The Strytan Hydrothermal Field (SHF) in basaltic terrain Iceland is one of the extant alkaline submarine hydrothermal vent systems favoured as analogues for where life on Earth may have begun. To test this hypothesis we analyse composition, structure, and mineralogy samples from chimneys generated at SHF. We find that chimney precipitates are composed Mg-silicates including clays saponite-stevensite group (high Mg Si, low Fe Al), Ca-carbonates Ca-sulfates. comprise permeable...
Chemical gardens and clock reactions are two of the best-known demonstration in chemistry. Until now these have been separate categories. We discovered that a chemical garden confined to dimensions is reaction involving phase change, so after reproducible controllable induction period it explodes.
Oil-shale (OS) self-heating retorting (SHR), which can spontaneously increase temperature in the absence of external heat provision, is a low-energy-input process but without cost loss oil yield. However, because OS decomposition extremely complex, sources used to form SHR are still unclear. In this work, semicokes obtained from and anaerobic (AR) analyzed compared for finding possible source. The results show that noticeable amount carbon remains (CRs) produced left semicoke byproduct...
Concentration cycles are important for bonding of basic molecular building components at the emergence life. We demonstrate that oscillations occur intrinsically in precipitation reactions when coupled with fluid mechanics self-assembled precipitate membranes, such as submarine hydrothermal vents. show that, moreover, flow ions across one pore a prebiotic membrane is larger than ion channel modern biological cell membrane, suggesting proto-biological processes could be sustained by osmotic...

Oil shale (OS) is a particularly promising alternative fossil fuel source. However, very different from coal, its inorganic mineral content high. The organic matters (mainly kerogen) are finely distributed in the minerals. Therefore, minerals may affect processing of OS, whose elucidation critical to choice conditions. In this work, (SiO2, CaCO3, and Al2O3) were added OS with mass ratios mineral, respectively. Then, thermogravimetric (TG) technique was employed analyze reaction behavior...
Chemical gardens are self-assembled structures of mineral precipitates enabled by semi-permeable membranes. To explore the effects gravity on formation chemical gardens, we have studied grown from cobalt chloride pellets and aqueous sodium silicate solution in a vertical Hele-Shaw cell. Through photography, observed quantitatively analysed upward growing tubes downward fingers. The latter were not seen previous experimental studies involving similar physicochemical systems 3-dimensional or...
We demonstrate experimentally and theoretically that self-assembled precipitate membranes with dual permeability can initiate maintain exchange nanoflows using the chemical-potential gradient of a dissolving solute. Moreover, we show how such chemical energy drive stable, oscillatory, explosive convective motions.Received 3 April 2019Accepted 24 June 2020DOI:https://doi.org/10.1103/PhysRevFluids.5.082201©2020 American Physical SocietyPhysics Subject Headings (PhySH)Research...
The osmotic rupture of a cell, its lysis or cytolysis, is phenomenon that active biological cell volume regulation mechanisms have evolved in the membrane to avoid. How then, at origin life, did first protocells survive prior such processes? pores alkaline hydrothermal vents oceans form natural nanoreactors which osmosis across mineral plays fundamental role. Here, we discuss dynamics and avoidance an abiotic system without any mechanisms, reliant upon self-organized behaviour, similar...
Abstract. Theoretical studies usually attribute convections to the developments of instabilities such as static or symmetric basic flows. However, following three facts make validities these theories unconvincing. First, it seems that in most cases flow with balance property cannot exist exact solution, so one formulate appropriate problems stability. Second, neither linear nor nonlinear dynamical instability are able describe a two-way interaction between convection and its background,...
