Temperature and Dynamic Effects of the Plate Boundary Shear Zone During Subduction

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The plate boundary in a subduction zone is a narrow, weak shear zone, which transitions from brittle to ductile deformation with increasing depth. The exhumed rock record documents the important role of metamorphism, fluid release, and mixing of compositionally distinct materials in controlling the physical properties of the shear zone.

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

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.
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 ...
