Oliver SteinbockNew perspective article on patterns and the future of #materials science with Pamela Knoll and Bin Ouyang. Big picture discussion of how dynamic spatiotemporal patterns are key to living systems & adaptive/active matter.
The "Nonequilibrium Composition of Mixed Metal Hydroxide Membranes Grown in Flow Systems" shows Ni:Mg gradients relating to growth speed. Maggie Cooper's first 1st -author paper in ACS Earth and Space Chemistry.
Two-page spread in the popular German science magazine 'Bild der Wissenschaft' highlighting our recent chemical garden model in @PNASNews https://doi.org/10.1073/pnas.2305172120 BdW has a circulation of >55,000 copies and is available at most German newsstands. #chemobrionics
"In any shape or form"
Philip Ball's latest column in RSC's Chemistry World looks at the fascinating challenge of distinguishing life-life inorganic shapes from true microfossils. Philip also discusses some of our recent work on chemical gardens. It's a very interesting read and includes topics such as the famous Mars meteorite ALH84001 and NASA's D'Arcy machine.
Our latest paper in Angew. Chem. reports that "Nonconventional Crystallization Causes Dendritic and Band-like Microscale Patterns in Inorganic Precipitates". Congrats to Jessica, Bruno, and Maggie.
First model of chemical gardens built around material aging and stochastic factors. Read our new paper in #PNAS by Bruno Batista and Amari Morris.
New paper in Soft Matter (RSC): Periodic bobbing motion of silica-CuO chemical gardens in H2O2. Rocket-like ascent at steady acceleration; horizontal landings at constant speed. Movement is captured by a model considering drag and gas production in the catalytic tube cavity.

Bobbing chemical garden tubes: oscillatory self-motion from buoyancy and catalytic gas production
Chemical reactions can induce self-propulsion by the production and ejection of gas bubbles from micro-rocket like cylindrical units. We describe related micro-submarines that change their depth in response to catalytic gas production. The structures consist of silica-supported CuO and are produced by utiliz
New paper in J. Phys. Chem. B: "Shape Evolution of Precipitate Membranes in Flow Systems" by Jessica Nogueira, Bruno Batista, Maggie Cooper et al. We use a nifty microfluidic device called "Junior" and derive a reaction-diffusion-advection model for the downstream thinning of Ni(OH)2.

#ChemicalGardens are inorganic self-assembled structures. They can nucleate silicate #crystals that embed the tubular shapes similarly to #mineral filaments in #agates. Our work on this is featured on the November cover of ACS Earth&Space Chemistry. Authors: P. Knoll, B. Batista, S. McMahon, O. Steinbock. Great job, Pam!!
