Integrated anti-electronics for positron annihilation spectroscopy [PDF]
Scientific ReportsImaging the features of a sample using Positron Annihilation Spectroscopy (PAS) is currently achieved by rastering, i.e. by scanning the sample surface with a sharply focused positron beam.

Molecular-Level Pore Engineering for Precise Separation via Active Solvent-Mediated Interfacial Polymerization. [PDF]
Adv Sci (Weinh)We demonstrate that microemulsion solvents can actively template molecular‐level pores within selective layer during interfacial polymerization. By creating localized quasi‐homogeneous polymerization zones, the membrane achieved a 7.1‐fold enhancement in water permeance with increased selectivity.

Charge-Transfer-Mediated Boron Magneto-Ionics: Towards Voltage-Driven Multi-Ion Transport. [PDF]
Adv Sci (Weinh)This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,
