Advanced Optical Materials, Volume 11, Issue 22, November 20, 2023., 2023 Microscale fluorescent Janus emulsions exhibit dynamically tunable, angle‐dependent light‐emission profiles that depend significantly on their composition and morphology. Informed by theoretical ray‐tracing calculations and closely matching experimental results, both the collection of incident light and the confinement of emitted light from inside the ...

Advanced Functional Materials, Volume 33, Issue 39, September 26, 2023., 2023 A novel ink system is presented allowing the fabrication of “living” microstructures using two‐photon laser printing and covalent adaptable chemistry of alkoxyamines. By application of nitroxide mediated polymerization and nitroxide exchange reaction mechanical properties as well as size of the microstructures are adjustable, while maintaining finest ...
