Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

Advanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Fructose‐Based Single‐Chain Polymer Nanoparticles for GLUT1–Mediated Delivery: Impact of Polymer Design on Uptake and In Vivo Performance

Advanced Healthcare Materials, EarlyView.
Single‐chain nanoparticles have been proposed as drug delivery carriers, but adding a tail can significantly enhance their performance. This was demonstrated using a tadpole‐like structure comprising a head prepared from a UV‐crosslinked fructose‐based glycopolymer capable of targeting GLUT receptors, combined with a PEG‐based tail. Compared with other
