Publication on strain-induced self-rolling of basic cobalt carbonate sheets in Chemical Communications
24th June 2021
Congrats to Viktoria Grün on the publication of her paper investigating the drying-induced self-folding of interface-derived mineral sheets!
Polyethyleneimine aids the gas diffusion precipitation of nano-structured basic cobalt carbonate sheets at the air/solution interface. Upon drying, these mineral films undergo self-rolling into 3D coiled structures. Exploring this principle for the design of self-supported functional materials, porous Co3O4 spirals composed of interconnected nanoparticles are obtained by thermal conversion.
For more information on these fascinating spiral structures see here.
