Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

VIEW Medicine, Volume 1, Issue 1, August 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

Heat‐Resistant Copper Alloys for Extreme Thermal Environments: Mechanisms, Architectures, and Design Strategies

cMat, Volume 3, Issue 2, June 2026.
ABSTRACT Copper (Cu) and copper‐based alloys are indispensable in high‐heat‐flux systems, such as aerospace propulsion, fusion reactors, and advanced power electronics, due to their high thermal conductivity and good manufacturability. However, extreme service conditions increasingly demand not only high thermal conductivity but also elevated ...

Impact of geometric factors and shear stress on endothelial function: Hemodynamic insights from human cerebral arterial bifurcations

Physiological Reports, Volume 14, Issue 11, June 2026.
Abstract Vascular inflammation is not a random biological event but rather a process that is strictly regulated by physical forces. While biochemical mediators are well characterized, the local physical mechanisms that predispose specific cerebral vascular sites to inflammation, specifically the geometry of arterial bifurcations, remain ...

Equal-Channel Angular Pressing of NiAl

, 2010
Equal-channel angular pressing (ECAP) was applied to polycrystalline NiAl at temperatures around the brittle-to-ductile transition temperature (BDTT). NiAl rods encapsulated in a steel jacket were ECAP-processed in a die with a channel angle of 120°. The

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, Volume 28, Issue 4, 18 February 2026.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.
