Viscoelasticity of Human Blood
Biophysical Journal, 1972 Measurements made for oscillatory flow of blood in circular tubes show that blood possesses elastic properties which make consideration of its viscous properties alone inadequate. Results are for a frequency of 10 Hz while varying the amplitude of the velocity gradient for red blood cells in plasma at concentrations ranging from 0 to 100% apparent ...

Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots
Advanced Materials, EarlyView.Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...

Reprogrammable Mechanical Metamaterials via Passive and Active Magnetic Interactions
Advanced Materials, EarlyView.The combination of flexible matrices with embedded hard‐magnetic nodes enables metastructures with reprogrammable mechanical properties, even in the absence of external magnetic fields. The evolving interaction between nodes during structural deformation allows mechanical tunability under quasi‐static and dynamic loading, and bistable transitions. This

Topology optimization of viscoelastic microstructures with acoustic impedance manipulation [PDF]
arXivMitigating low-frequency noise is particularly challenging due to its limited natural attenuation. This study aims to design viscoelastic composite microstructures that achieve both low acoustic reflection and high internal damping by simultaneously optimizing their effective acoustic impedance and attenuation characteristics.

Advanced Materials, EarlyView.The SciAgents AI model drives hypothesis generation by harnessing multi‐agent graph reasoning, extracting insights from knowledge graphs constructed from scientific papers. Each agent plays a specific role: the Ontologist defines concepts, the Scientists draft and refine proposals, and the Critic reviews.

Effect of Visco-Elasticity of an Orthotropic Arterial Wall on Pulse-Wave Propagation
Механика машин, механизмов и материалов, 2008 The problem of harmonic pressure wave propagation through a viscous fluid contained in a thin viscoelastic orthotropic tube is considered. To take into account viscoelasticity of the tube the linear viscoelasticity model is used.
