Advanced Science, EarlyView.Water‐soluble amine‐functionalized polyhedral oligomeric silsesquioxane promotes concurrent latex coalescence and crosslinking, allowing epoxy‐functional particles to form continuous films without added volatile coalescing agents. The resulting multiscale‐reinforced waterborne coatings combine high strength, toughness, optical transparency, scratch ...

Advanced Science, EarlyView.Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

Angewandte Chemie, EarlyView.This study demonstrates that indium clusters with 6s2 lone‐pair effect anchored on carbon nitride act as excitonic electron reservoirs to boost charge separation and O2 activation for highly selective direct 2e− oxygen reduction. This work establishes cluster‐mediated electron reservoir engineering as a general strategy for enhancing selective ...

Advanced Science, EarlyView.Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...

Angewandte Chemie, EarlyView.The engineered DTSe‐based photosensitizer, DZTSe, emerges as an avant‐garde molecular entity, which can distribute to both the endoplasmic reticulum and mitochondria to concurrently trigger pyroptosis and activate the cGAS‐STING pathway. This dual‐action strategy effectively reprograms the tumor microenvironment, enabling potent eradication of primary ...

Passive and hybrid mode locking in multi-section terahertz quantum cascade lasers
New Journal of Physics, 2018 It is believed that passive mode locking is virtually impossible in quantum cascade lasers (QCLs) because of too fast carrier relaxation time. Here, we revisit this possibility and theoretically show that stable mode locking and pulse durations in the ...
