Design of Experiments (DoE)‐Optimized Polymeric Oxytocin Nanoparticles for Enhanced Nose‐to‐Brain Delivery

open access: yesSmall, EarlyView.
Intranasal (IN) delivery of PEGylated PLGA nanoparticles (NPs) loaded with oxytocin (OT) (OT‐NP‐PEG) is investigated as a strategy to enhance OT transport to the brain for treating autism and other neuropsychiatric disorders. The optimized NP formulation demonstrates appropriate physicochemical characteristics, improved stability, and enhanced mucosal ...

Heterointerface Engineering of FeOOH@Ni3N Electrocatalysts for Industrially Compatible Alkaline Water Electrolysis

open access: yesSmall, EarlyView.
A hierarchically structured FeOOH@Ni3N electrocatalyst supported on Ni foam enables high‐rate alkaline water electrolysis with industrial‐level stability. Operando spectroscopy reveals that the Fe–Ni heterointerface stabilizes high‐valent Ni4+ = O/Fe4+ = O species and promotes a hydroxyl nucleophilic attack (HNA) mechanism, wherein OH− attack on ...

Versatile High‐Sensitivity EPR Using Superconducting Spiral Microresonators

open access: yesSmall Methods, EarlyView.
A significant sensitivity enhancement in conventional X‐band pulsed EPR is achieved using planar spiral microresonators fabricated from high‐temperature superconducting YBCO. Fully compatible with standard instrumentation, the approach enables high‐fidelity spin control under typical sample conditions.
