Advanced Science, EarlyView.Precise modulation of reaction pathways remains an unresolved challenge in peroxymonosulfate‐activated advanced oxidation processes. The spatial preorganization strategy in engineered confinement architecture enables regioselective bond cleavage in monoethanolamine via synergistic proton–electron transfer, redirecting its degradation from nonselective ...

Chaotic analogue‐to‐information conversion with chaotic state modulation
IET Signal Processing, 2014 Chaotic compressive sensing is a non‐linear framework for compressive sensing. Along the framework, this study proposes a chaotic analogue‐to‐information converter, ‘chaotic modulation’, to acquire and reconstruct band‐limited sparse analogue signals at sub‐Nyquist rate.

Advanced Science, EarlyView.We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Advanced Science, EarlyView.This study demonstrates a TiN/HfO2/ITO memristor exhibiting field‐induced bimodal volatile switching behavior originating from ion bombardment during sputtering. The dipole‐driven, polarity‐dependent states produce multilevel output responses that expand the reservoir's output dimensionality and enhance encoding diversity.

Advanced Science, EarlyView.Anode‐free Li–S cells are realized by coupling nano‐Li2S embedded in P‐doped porous carbon nanofibers (Li2S@P‐CNFs) with lithium‐free P‐CNF current collectors. Polar P‐CNFs accelerate Li2S conversion and suppress shuttling, while their lithiophilic, macroporous network homogenizes Li plating for dendrite‐free deposits.
