Bioinspired Morphology‐Decoupled Soft Gripper with Enhanced Bidirectional Grasping Capability

open access: yesAdvanced Science, Volume 13, Issue 34, 19 June 2026.
Inspired by biological predation, a novel gripper decouples cross‐modal grasping via dual morphological configurations. Synergistically integrating hybrid rigid and soft coupled fingers with a metamaterial palm, the system performs active compliant grasping for static objects and passive cage capture for dynamic targets.

Computational Rheo‐Hydrodynamic Analysis of Non‐Newtonian Blood Flow Through a Tilted Ellipsoidal Stenosed Vascular Segment

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Non‐Newtonian blood flow through multiple tilted ellipsoidal stenoses is numerically investigated using the DeKee‐Turcotte‐Papanastasiou model. The results reveal asymmetric velocity fields, elevated wall shear stress, significant pressure drops, and shear‐dependent thermal effects, highlighting the critical hemodynamic risks associated with eccentric ...

Influence of Symmetric Multi‐Overlapping Stenosis on Carreau Blood Rheology: A 3D Computational Study

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Graphical summary of the proposed problem. ABSTRACT Arterial conduits with more than two consecutive constrictions are classified as exhibiting multiple overlapped stenoses, a pathological morphology with critical implications for vascular health. Accurate comprehension of the associated hemodynamic behavior necessitates advanced geometric modeling and

Direct Steam Generation in Parabolic Trough Collectors

open access: yesEnergy Procedia, 2014
Existing commercial parabolic trough power plants use thermal oil as a heat transfer fluid, with working temperatures in the region of 400ºC. In order to achieve more efficient generating systems, a second generation of parabolic troughs that operate at temperatures higher than 400ºC is being developed.
