AI‐Directed 3D Printing of Hierarchical Polyurethane Foams

Advanced Science, EarlyView.
Digitally guided direct ink writing, combined with AI‐generated design, enables the fabrication of hierarchical polyurethane foams with tunable multiscale porosity. This approach produces architected foams featuring interconnected open‐cell networks and tailored mechanical properties, advancing the development of adaptive, high‐performance materials ...

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals

Advanced Science, EarlyView.
Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

OCTN2 Activates a Non‐Canonical Carnitine Metabolic Pathway to Promote MASH‐HCC Progression and Immunotherapy Resistance

Advanced Science, EarlyView.
In non‐MASH‐HCC, L‐carnitine promotes tumor progression primarily through its classical role in enhancing fatty acid oxidation (FAO). However, in MASH‐HCC, where FAO is markedly suppressed, L‐carnitine shifts from this canonical function to serve instead as an intracellular acetyl group buffer.

Overlapping Schwarz Preconditioners for Isogeometric Collocation Methods Based on Generalized B-Splines

Axioms
We study overlapping additive Schwarz (OAS) preconditioners for the solution of elliptic boundary value problems discretized using isogeometric collocation methods based on generalized B-splines (GB-splines). Through a series of numerical experiments, we

Endothelial Cell‐Based Vascular Bandages for Blood–Brain Barrier Repair and Targeted siRNA Delivery

Advanced Science, EarlyView.
mECs restore blood–brain barrier function after cerebral ischemia–reperfusion by simultaneously targeting, supporting, and regulating the damaged vasculature. mECs home to injured cerebral vessels through interactions with highly expressed VLA‐4, reinforce endothelial integrity by forming new junctions, and, upon OGD‐SN treatment, acquire enhanced ...
