Joule‐Assisted Nanotherapeutic Urethral Stent (JANUS) for Spatiotemporal Theragenerative Treatment of Urethral Strictures

open access: yesAdvanced Functional Materials, EarlyView.
Joule‐assisted nanotherapeutic urethral stent harnesses a smart, biodegradable magnesium stent to orchestrate spatiotemporal theragenerative therapy for urethral strictures. Magnetically induced Joule heating enables on‐demand drug release and bacterial ablation, while simultaneously guiding urothelial regeneration.

Switching and energy-storage characteristics in PLZT 2/95/5 antiferroelectric ceramic system [PDF]

open access: yesJournal of Advanced Dielectrics, 2016
Switching mechanisms and energy-storage properties have been investigated in (Pb0.98La0.02)(Zr0.95Ti0.05)0.995O3 antiferroelectric ceramics. The electric field dependence of polarization (P–E hysteresis loops) indicates that both the ferroelectric (FE ...

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

Incorporation of dysprosium ions into PbTiO3 ferroelectric ceramic system [PDF]

open access: yesJournal of Advanced Dielectrics, 2015
A structural analysis concerning the incorporation of dysprosium into A- and/or B-sites of the lead titanate is shown. The two "boundary" refinements are presented, i.e., Dy2+ substitutes for Pb2+ (Dy3+ substitutes for Ti4+) and Dy3+ substitutes for Pb2+

Effects of Ti content on dielectric and energy storage properties of (Pb0.94La0.04)[(Zr0.70Sn0.30)1−xTix]O3 ferroelectric/antiferroelectric ceramics [PDF]

open access: yesJournal of Advanced Dielectrics, 2016
Ferroelectric/antiferroelectric (FE/AFE) ceramics with composition of (Pb0.94La0.04)[(Zr0.70Sn0.30)1−xTix]O3 were fabricated via solid state reaction and the effects of Ti content on dielectric and energy storage properties were studied.
