Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,

Tuning cohesive interactions of porphyrins for selective two‐electron oxygen reductions

open access: yesAIChE Journal, EarlyView.
Abstract Selective two‐electron oxygen reduction reaction (ORR) provides a sustainable route for hydrogen peroxide production, with broad industrial and environmental applications. However, controlling over ORR selectivity remains challenging due to the competing four‐electron pathway (i.e., over‐reduction of oxygen to water).
