Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

Artificial Organs, EarlyView.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

In Situ Preparation of Ti2Ni/NiTi Dual‐Phase Alloy With High Wear Resistance and Damping Performance by Additive Manufacturing

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Many metallic components are frequently subjected to coupled environments of friction and vibration, stemming from interfacial contact and relative motion between mating parts or external stimuli. Consequently, it is imperative for these components to exhibit a synergy of high wear resistance and superior damping properties.

Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

Artificial Organs, Volume 50, Issue 8, Page 1125-1135, August 2026.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

Unsteady Flow Behavior and Radial Force Analysis of a Side Channel Pump Under Different Blade Tip Cutting Angles Using Computational Fluid Dynamics

Energy Science &Engineering, Volume 14, Issue 7, Page 3458-3471, July 2026.
The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 371-382, July 2026.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures
