An Optimized Multi‐Stage Drainage Cannula Design for Venoarterial Extracorporeal Membrane Oxygenation

Artificial Organs, EarlyView.
This study utilized an extensive optimization involving n = 540 design of experiments to produce a superior drainage cannula design. Compared to the clinically used Maquet model, our optimized design demonstrated reduced blood stagnation volumes, increased cannula tip velocities, and higher upper body drainage, potentially minimizing risk of thrombosis

Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

Polymer Composites, Volume 47, Issue 15, Page 13910-13926, 10 August 2026.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...

Design of Experiments‐Based Optimization of Recovered Carbon Black–Reinforced Isobutylene–Isoprene Rubber in Comparison With Conventional Carbon Black Systems

Journal of Applied Polymer Science, Volume 143, Issue 27, July 15, 2026.
Optimized potential of rCB via DOE: recovered carbon black from end‐of‐life tires was assessed as a full substitute for conventional carbon black in IIR composites. DOE and response surface methodology optimized rCB loading, plasticizer, and sulfur contents. Hardness showed linear trends, while rupture energy was nonlinear.
