Alkaline hydrothermal vents have become a candidate setting for the origins of life on Earth and beyond. This is due to several key features including presence gradients temperature, redox potential, pH, availability inorganic minerals, existence network pore spaces that could served as primitive compartments. Chemical gardens long been used experimental proxies vents. paper investigates-10pc]Please note spelling following author name in manuscript differs from provided article metadata:...

In a recently published paper (doi.org/10.3390/molecules26113116) on self-propelled motion of objects the water surface, we described novel surface-active plastic material obtained by dissolution camphor and polypropylene in camphene at 250 [Formula: see text]C. The has wax-like mechanical properties, can be easily formed to any moldable shape, allows for longer more stable if compared with pure or camphene-camphor wax. Here use scanning electron microscopy visualize characterize microporous...

We consider the motion of a self-propelled object rectangular shape inside circular water chamber. The mathematical model self-motion includes equations for orientation and location rectangle reaction-diffusion equation with an effective diffusion coefficient time evolution surface concentration active molecules. Numerical simulations were performed different values ratio between supply rate S evaporation Treating S0 = S/a as control parameter, we found critical behavior in variables...

Artificial cells can be engineered to display dynamics sharing remarkable features in common with the survival behavior of living organisms. In particular, such active systems respond stimuli provided by environment and undertake specific displacements remain out equilibrium, e.g. moving towards regions higher fuel concentration. spite intense experimental activity aiming at investigating this fascinating behavior, a rigorous definition characterization "survival strategies" from statistical...

We describe a novel plastic material composed of camphene, camphor, and polypropylene that seems perfectly suited for studies on self-propelled objects the water surface. Self-motion is one attributes life, chemically propelled show numerous similarities with animated motion. One important questions relationship between object shape its motility. In our paper published in 2019, we presented hybrid material, obtained from solution camphor allowed making various shapes. This has wax-like...

Droplets of paraffin can show self-motion when powered by camphor.We investigated the motion such droplets varying concentrations camphor and dye, Oil Red O, as well droplet volume.Experiments have shown that presence O dye in system significantly increase complexity evolution, if compared to case where is absent.Just increasing concentration achieves a complex evolution before it splits into many self-propelled secondary objects expressing similar progenitor droplet.Therefore, replicates...

Two droplets composed of different chemicals, 1-decanol and liquid paraffin, floating on the water surface show characteristic co-responsive behavior. The presence two types in system imposes an asymmetry that would not be possible with single alone. self-propulsion interactions between appear because active molecules provided by source are absorbed paraffin sink thus generating asymmetric tension gradient. This source-sink relation stabilizes enhances self-propulsion, leads to a variety...

We highlight camphene-camphor-polypropylene plastic as a useful material for self-propelled objects that show aggregation while floating on water surface. consider rods an example of characterized by non-trivial individual shapes with low-symmetry interactions between them. The motion made the is supported dissipation surface-active molecules. physical processes leading to and mathematical model process are discussed. analyze experimental data aggregate formation dynamics relate them...
