Single-Particle Photophysics Reveals Pathway-Dependent Packing in Kinetically Trapped Hydrophobic Aggregates

Abstract Hydrophobic self-assembly frequently produces kinetically trapped, nonequilibrium aggregates whose internal molecular packing is difficult to control and characterize. Here, using a donor–acceptor aggregation-induced-emission probe, we show that the onset concentration o...

Quantitative Quantum Relaxometry Framework for Probing Transient Radical-Associated Magnetic Fluctuations under Operando Conditions

Abstract Transient paramagnetic intermediates play central roles in interfacial chemical and biological processes. However, their short lifetimes make dynamic probing difficult. Existing methods typically rely on reporter chemistry or spin adducts, limiting continuous, operando m...

Interface-controlled phase stability in polymorphic HfO2 revealed by machine-learning atomistic simulations

HfO 2 exhibits rich polymorphism, and competition among different phases underpins many of its functional properties. Yet bulk free-energy relations alone cannot explain phase selection at mixed-phase boundaries, where interface orientation and structural continuity constrain col...
