A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

open access: yesAdvanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...

B‐Site Multi‐Element Micro‐Doping Engineered Air Electrodes With Fast Oxygen Kinetics for Reversible Protonic Ceramic Electrochemical Cells

open access: yesAdvanced Science, EarlyView.
Mo‐tuned multi‐element micro‐doping regulates redox chemistry, oxygen nonstoichiometry, hydration, and interfacial kinetics in PBSCF‐derived air electrodes for reversible protonic ceramic electrochemical cells. The cell with optimized PBSCFMNM03 air electrode delivers 1.10 W cm−2 in fuel cell mode and 1.88 A cm−2 at 1.3 V in electrolysis mode at 650 °C,

Electron‐Rich Nickel Enabled by Charge Transfer in Multimetal Nanostructures for Efficient Ammonia‐to‐Hydrogen Conversion

open access: yesAdvanced Science, EarlyView.
A charge‐transfer‐engineered Ni catalyst derived from an atomically mixed layered precursor enables efficient ammonia‐to‐hydrogen conversion. Cr‐to‐Ni electron transfer creates electron‐rich Ni active sites that favor NH3 adsorption, modify the dehydrogenation energetics, and weaken N2 binding to facilitate product desorption. This electronically tuned

Sequence‐Controlled Copolymers Through Selective Ring‐Opening Polymerization of Multiunit Macrolactones

open access: yesAdvanced Science, EarlyView.
Sequence‐controlled polymers were prepared through ring‐opening polymerization (ROP) exploiting esters with enhanced reactivity in the multiunit monomer induced by incorporation of a glycolate group, enabling selective ROP. ABSTRACT A new strategy for the synthesis of sequence‐controlled polymers (SCP), in which increased ester reactivity by the ...

Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria

open access: yesAdvanced Science, EarlyView.
A non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO2 Electrolysis in Gas Diffusion Electrodes

open access: yesAdvanced Science, EarlyView.
In gas‐fed CO2${\rm CO}_2$ electrolysers, the gas phase is part of the electrochemical response. As gaseous products form, they change gas composition and flow, which in turn affects CO2${\rm CO}_2$ delivery and CO intermediate availability. This feedback changes the reaction environment needed for multicarbon formation, becoming unavoidable as ...
