Supraparticle Powders
Controlling the structure and porosity in hierarchical materials is a key design feature that can enable their successful application in fields of chromatography, catalysis and adsorption. In article number 2300241, Benjamin Apeleo Zubiri, Alexandra Inayat, Nicolas Vogel, and co‐workers provide a versatile toolbox for designing hierarchical porous materials by tailoring the porosity...
A drying droplet containing colloidal particles can consolidate into a spherical assembly called a supraparticle. Such supraparticles are inherently porous due to the spaces between the constituent primary particles. Here, the emergent, hierarchical porosity in spray‐dried supraparticles is tailored via three distinct strategies acting at different length scales. First, mesopores (<10 nm) are introduced...
Optical microscale shear‐stress indicator particles are of interest for the in situ recording of localized forces, e.g., during 3D printing or smart skins in robotic applications. Recently developed particle systems are based on optical responses enabled by integrated organic dyes. They thus suffer from potential chemical instability and cross‐sensitivities toward humidity or temperature. These drawbacks...
Supraparticles are spherical colloidal crystals prepared by confined self‐assembly processes. A particularly appealing property of these microscale structures is the structural color arising from interference of light with their building blocks. Here, we assemble supraparticles with high structural order that exhibit coloration from uniform, polyhedral metal–organic framework (MOF) particles. We analyse...
