Phase‐Dependent Oxygen Defect Energetics in Epitaxial NbN/AlN/NbN Films

open access: yesAdvanced Science, EarlyView.
Phase dependent oxygen defect energetics in epitaxial δ‐NbN/AlN/δ‐NbN and β‐Nb2N/AlN/β‐Nb2N trilayers. Atomic‐scale analysis and first‐principles calculations reveal distinct oxygen incorporation pathways across NbN polymorphs. Layer resolved defect formation energies show that O is energetically more favorable within δ‐NbN electrodes, whereas in β ...

Gut Microbiota‐Isoallolithocholic Acid Crosstalk Promotes Calcium Oxalate Kidney Stone Formation via PARP1‐Mediated Parthanatos

open access: yesAdvanced Science, EarlyView.
ABSTRACT Bile acids have been implicated in calcium oxalate (CaOx) nephrolithiasis. Here, we employ multi‐omics approaches to identify isoallolithocholic acid (isoalloLCA) as the key bile acid elevated in the feces, serum, kidney, and urine of CaOx rats, confirmed by spatial metabolomics.

KLF5 Downregulation Links Impaired BNIP3‐Mediated Mitophagy to Inflammatory Valve Remodeling in Calcific Aortic Valve Disease

open access: yesAdvanced Science, EarlyView.
In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

Responsive Open Microfluidic Logic for Mechanical Computing

open access: yesAdvanced Science, EarlyView.
Coupling elasticity with capillarity transforms mechanical compression into binary fluidic states, enabling deterministic logic in open microfluidic circuits. This work demonstrates that computation can emerge from interactions between mechanic and fluidic domains, establishing a general strategy for embedding information processing directly within ...
