A study published in PNAS reveals that active matter and shear flows exhibit similar thinning behaviors due to micro-mechanism of breaking up percolating particle clusters. This finding offers a possible explanation for the 'superfluid'-like phenomena observed in biological organisms.
The new metafluid can transition between Newtonian and non-Newtonian states, allowing for programmable viscosity and compressibility. The researchers demonstrated the fluid's capabilities in a hydraulic robotic gripper, picking up objects of varying weights without crushing them.
Caterpillars of the Carolina sphinx moth have an extraordinary ability to instantly change their hemolymph's material properties, turning it into a viscoelastic fluid that helps stop bleeding. This discovery has potential applications for developing new drugs for humans to create fast-working thickeners of human blood.
Researchers found that sperm flagellar waveforms are primarily influenced by viscosity rather than shear rate, promoting energy-efficient beating behavior. Sperm adjust their power generation to respond to fluid dynamics, enabling efficient swimming against the flow in high-viscosity media.
Associate Professor Tadashi Ando from Tokyo University of Science conducted a study to test the performance of OPC and OPC3 water models, evaluating their shear viscosities and comparing values to experimental calculations. The calculated viscosities for both models were very close, with notable accuracy at temperatures above 310 K.
Scientists study flow patterns from heavy-ion collisions to understand fluctuations in particle behavior, aiming to calculate the properties of quark-gluon plasma. The results point to initial state influences as the primary trigger for these fluctuations, with collision energy and nucleus size also playing a role.
Shear thickening occurs when particles in a low-viscosity solution behave like a solid under stress. Researchers at North Carolina State University captured microscopic images of particles as they underwent shear thickening, revealing complex networks formed between particles and their shapes dependent on particle roughness.
Researchers discovered that food-grade polymers can completely eliminate aerosolization of saliva droplets in dental settings. The polymers' viscoelastic properties restrict water aerosolization by creating snakelike strands that pull droplets back, preventing aerosolization.
