NMR data for the hydroxyl groups detected by NOESY spectra in sesquiterpene lactones

Data in Brief, 2019
In this article we present the correlations observed in the NOESY spectra, which provide direct and unequivocal detection of hydroxyl groups occurring in the chemical structures of three sesquiterpene lactones - a germacranolide (8α-(E)-4 ...

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

Advanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

Advanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

Advanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.
