Advanced 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 ...

Hydrogen-bonding interactions in gas-phase polyether/ammonium ion complexes
, 1994 Hydrogen bonds are among the most important interactions involved in selective complexation in host—guest chemistry. In this study a variety of hydrogen-bonded crown ether/ammonium ion complexes are generated in the gas phase by association reactions ...

Advanced Science, EarlyView.A self‐generated Li–Si alloy interface transforms carbon‐free micro‐silicon into a kinetically accelerated and mechanically resilient anode for sulfide‐based all‐solid‐state batteries. Serving simultaneously as an active lithium reservoir and conductive interface, the alloy layer compensates lithium loss while accommodating volume changes, enabling 89 ...

Toward Rational Design of Aqueous Battery Membranes Beyond the Selectivity‐Conductivity Trade‐Off
Advanced Science, EarlyView.This review examines sulfonated membranes for redox flow batteries. It focuses on proton transport mechanism, membrane design, performance limits, optimization strategies, and the pathway from molecular design to membrane manufacturing. ABSTRACT Electrochemical energy‐storage systems increasingly require membranes that can simultaneously deliver fast ...

Thermal Stability of Polyester vs. Polyether-Based Urethans
, 1969 It has been shown, by means of continuous and intermittent stress relaxation measurements and oven aging studies, that polyester-based urethans are more resistant to thermal degradation than the corresponding polyether-based urethans at temperatures in ...

Advanced Science, EarlyView.A bio‑based thermoresponsive controlled‑release fertilizer (TRBF) is fabricated by introducing F127 into a castor‑oil‑derived polyurethane coating. Distinct from conventional bio‑based coated fertilizer (BCF), TRBF achieves temperature‑regulated nitrogen release via F127 reversible phase transition, suppressing nutrient leakage at low temperature and ...

The Synthesis and Characterization of Polyether-Modified Polysiloxane Phosphate
, 2010 In order to combine the properties of phosphate surfactants and silicone surfactants, the polyether-modified polysiloxane phosphate (PPSP) was prepared. Firstly, the intermediate was synthesized through the hydrosilylation of hydricpolysiloxane and alkyl
