By nanoscale 3D printing, we produced miniaturized optical components processing information in the color and orbital angular momentum of beamlets using only light from a lamp. These colored vortex beams from incoherent white light promise anticounterfeiting through pairwise optical authentication.

Highly-efficient large area perovskite light-emitting diodes with high uniformity using colloidal perovskite nanocrystals were realized with the development of the simple modified-barcoating which facilitates the evaporation of residual solvent.

Story behind the paper: 'Photocatalytic degradation of steroid hormone micropollutants by TiO2-coated polyethersulfone membranes in a continuous flow-through process', scheduled for publication in Nature Nanotechnology on 31 March 2022

While trying to experimentally uncover what is the physical mechanism that governs plasmon-mediated chemistry, its energy-dependent nature was revealed.
