Defect Engineering Activates Pyrene‐Based Covalent Organic Frameworks for Efficient Photocatalytic Uranium Capture

open access: yesAdvanced Science, EarlyView.
A defect‐engineered pyrene‐based covalent organic framework (TP‐PYTO‐SA) is developed via strategic salicylaldehyde incorporation. This approach simultaneously enhances hydrophilicity and introduces uranyl coordination sites, while optimized defect density significantly improves charge separation.

Fe/N‐Doped Carbon with Nearly Ordered Mesopores and Tunable Particle Sizes as Model Catalysts for Quantitative Evaluation of Electrocatalytic Active Sites

open access: yesAdvanced Science, EarlyView.
This study is dedicated to the design and synthesis of MOF‐derived mesoporous Fe/N‐doped carbons as model catalysts, aiming to quantitatively evaluate the utilization of active sites in the ORR. Through modulation followed by pyrolysis, we successfully prepare size‐tunable Fe/MNC‐x with doped iron atoms and mesoporous structures. The smaller Fe/MNC‐250

Mineralized Cryogel/Hydrogel Constructs to Recapitulate Early Breast Cancer Bone Metastasis In Vitro

open access: yesAdvanced Science, EarlyView.
A new biphasic in vitro cryogel/hydrogel model of early breast cancer bone metastasis provides precise control over microenvironmental cues and microscopic access to the spatiotemporal cancer cell distribution. Deposited bone‐like mineral is observed to strongly impede the effects of biomolecular signals, as evidenced by both colonization profiles and ...

Xanthatin Targets CISD1 to Drive Ferroptosis and Mitophagy as a Dual Anticancer Strategy in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
Triple‐negative breast cancer has a poor prognosis. Xanthatin directly targets and degrades CISD1, triggering ferroptosis through iron dysregulation. The concurrently activated mitophagy synergistically amplifies ferroptotic cell death. Xanthatin also demonstrates potent in vivo anti‐tumor efficacy with minimal toxicity, highlighting its therapeutic ...

Encapsulating Textiles with Dynamic Covalent Networks for Sustainable and Efficient Oil Spill Cleanup

open access: yesAdvanced Science, EarlyView.
By encapsulating industrially relevant fabrics with dynamic imine networks, we show that the resulting composites exhibit exceptional oil absorbtion capability and chemical recyclability. It is poised for sustainable oil spill cleanup. ABSTRACT The development of high‐performance sorbents for oil spill remediation is highly desirable, which now calls ...
