Gram‐Scale Synthesis of Hafnium‐Rich Carbon Dots for Preclinical Computed Tomography Imaging Across Various Systems

open access: yesAdvanced Science, EarlyView.
Hafnium (Hf)‐rich carbon dots (Hf‐rCDs) with high metal content (40.7%) and robust batch production capacity (>2 g per batch) are synthesized via a facile air‐assisted pyrolysis method. In vivo CT imaging demonstrates outstanding performance of Hf‐rCDs across multiple physiological systems and enables high‐resolution visualization of swine cervical ...

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

open access: yesAdvanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

open access: yesAdvanced Science, EarlyView.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

open access: yesAdvanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

open access: yesAdvanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...
