A Constraint‐Based Analytical Framework for Design‐Space Analysis and Material Screening of Tubular Multilayer Dielectric Elastomer Pumps for Extracorporeal Circulatory Applications

Advanced Materials Technologies, EarlyView.
A constraint‐based analytical framework maps the coupled effects of material properties, structural parameters, and operating conditions in tubular dielectric elastomer pumps for extracorporeal circulatory applications. The approach defines performance boundaries through mechanical, electrical, and hydraulic constraints and identifies feasible design ...

Hydraulic engineering in the social-ecological delta: understanding the interplay between social, ecological, and technological systems in the Dutch delta by means of "delta trajectories."

Ecology and Society, 2016
Several of the world's largest deltas have recently been conceptualized as social-ecological delta systems. Although such conceptualizations are valuable in emphasizing complex interaction between social actors and ecological processes in deltas, they do

Synergistic Interfacial Regulation by Nano‐TiO2 and Carboxylated Cellulose Nanofibers for Multiscale Surface Stabilization of Cementitious Composites

Advanced Materials Technologies, EarlyView.
Nano‐TiO2 and carboxylated cellulose nanofibers jointly regulate hydration‐product distribution in cementitious composites. Improved microstructural continuity and refined pore structure accompany enhanced strength and surface stability without a substantial increase in overall hydration.
