Co‐Solvation Tunes Ion Pairing and Interphases to Stabilize High‐Voltage Sodium Metal Batteries

Md Sharif Khan, M. Akif Rahman, Hossein Shahali, Guotao Wang et autres

ABSTRACT Electrolytes that enable sodium‐metal batteries to operate reliably at sub‐zero temperatures must simultaneously satisfy fast bulk transport, low Na + desolvation barriers, high‐voltage stability, and mechanically robust interphases requirements that are intrinsically coupled in conventional single‐solvent systems. Here we introduce a …

Vascular Transpiration in a Carbon-Carbon Composite Leading Edge

Mark Olima, Mohammed Ammar Abdul latheef, William LePage, Hema Ramsurn et autres

Carbon-carbon (C/C) composites are among the few structural materials capable of surviving the aerothermal environment of hypersonic flight, yet integrating active cooling into a monolithic C/C leading edge without thermal expansion mismatch, assembly complexity and flow impingement has not previously been demonstrated. …

Data-Driven Study of Preceramic Polymers for SiC Composites with Emphasis on Curing Behavior and Ceramic Yield

Slavica Porobic Katnic, Ben J. Blaiszik, Ramona Naghi, Hema Ramsurn et autres

Abstract The design of polymer-derived silicon carbide (SiC) composites has largely relied on trial and error, as decades of foundational studies remain scattered across unstructured literature. This fragmentation has hindered systematic efforts to resolve a central conflict in the development of SiC …

Curing Mechanisms of an Allyl‐Functionalized Preceramic Polymer With Radical Initiators: Kinetics and Thermodynamics

Slavica Porobic Katnic, Mohammed Ammar Abdul latheef, Michael K. Cinibulk, William LePage et autres

ABSTRACT This study investigates the thermal curing behavior of allyl‐functionalized SMP‐10, a preceramic polymer used as a silicon carbide (SiC) precursor in ceramic matrix composites (CMCs). The relatively high curing temperature of SMP‐10 may pose a significant processing challenge, as it can …
