Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Tunable Bioresorbable Scaffolds With Marine Sulfated Polysaccharides for Small‐Caliber Vascular Grafts: A Multi‐Layered Strategy Combining Electrospinning and 4‐Axis Printing

Advanced Healthcare Materials, EarlyView.
A multilayered small‐caliber vascular scaffold combining electrospinning and 4‐axis printing is developed and biofunctionalized with marine sulfated polysaccharides from Holothuria tubulosa. The resulting construct exhibits enhanced hemocompatibility, tunable mechanical properties, and supports endothelial and smooth muscle cell adhesion and ...

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
