"deep-penetration #acoustic volumetric #printing (DAVP) achieves the key features of low acoustic streaming, rapid sonothermal #polymerization, and large printing depth, enabling the printing of #volumetric hydrogels and #nanocomposites with various shapes regardless of their #optical properties. DAVP also allows printing at centimeter depths through #biological tissues, paving the way toward minimally invasive #medicine"

Revealing the pattern between frontal #polymerization and #naturalconvection @uofigrainger @physrevlett https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.028101 https://phys.org/news/2023-03-revealing-pattern-frontal-polymerization-natural.html
A self-propagating chemical reaction can transform a liquid monomer into a solid polymer, and the interaction between the propagating front and the reaction's natural convection leads to patterns in the resulting solid polymeric material. New University of Illinois Urbana-Champaign work has shown how the coupling between natural convection and frontal polymerization leads to those observed patterns.
