Indolo‐Fused MR‐TADF Materials and their Application in Organelle‐Targeted Bioimaging
Advanced Functional Materials, EarlyView.Using indolo‐fusion and sulfur bridging, four multi‐resonance thermally activated delayed fluorescent (MR‐TADF) materials are reported based on the quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) framework. Functionalization of these dyes with phosphonium groups enables cellular imaging with mitochondrial targeting in glassy organic nanoparticles ...

A passive Stokes flow rectifier for Newtonian fluids
Scientific Reports, 2021 Non-linear effects of the Navier–Stokes equations disappear under the Stokes regime of Newtonian fluid flows disallowing a flow rectification behavior. Here we show that passive flow rectification of Newtonian fluids is obtainable under the Stokes regime

Diffusion Processes in the A-Model of Vector Admixture: Turbulent Prandtl Number
EPJ Web of Conferences, 2018 Using analytical approach of the field theoretic renormalization-group technique in two-loop approximation we model a fully developed turbulent system with vector characteristics driven by stochastic Navier-Stokes equation. The behaviour of the turbulent

Advanced Functional Materials, EarlyView.This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.
