In 1738, Daniel Bernoulli discovered the principle that increasing the flow of a gas or liquid decreases its pressure. #Poetry #Science #History #Hydrodynamics #Bernoulli (https://sharpgiving.com/thebookofscience/items/p1738.html)

C'est plus la Saint-Valentin mais ça se tente, pour séduire... 😘

Explication : lorsque j'utilise mon doigt pour créer une forme de cœur ❤️ dans l'eau, cela crée une petite vague/petite perturbation dans la tension superficielle qui modifie la façon dont l'eau s'écoule dans cette zone. C'est ce qui fait que l'eau s'étale en forme de cœur.

#SoftMatter have just published the results of a project that Renato Assante, Davide Marenduzzo, Alexander Morozov, and I recently worked on together! What did we do and what’s new? Briefly…

#Microswimmer suspensions behave in a similar way to fluids containing kinesin and microtubules. Both systems can be described by the same system of three coupled nonlinear #PDEs.

A #LinearStabilityAnalysis of these equations suggests that variations in concentration across the system don’t significantly affect emergent #phaseBehaviour. How then can we explain #experiments that show visible inhomogeneities in #microtubule–#kinesin mixtures, for instance?

With increasing activity, we move away from the quiescent regime, past the onset of #SpontaneousFlow, and deeper into the active phase, where #nonlinearities become more important. What role do concentration inhomogeneities play here?

We investigated these questions, taking advantage of the #openSource #Dedalus #spectral framework to simulate the full nonlinear time evolution. This led us to predict a #novel regime of #spontaneous #microphaseSeparation into active (nematically ordered) and passive domains.

Active flow arrests macrophase separation in this regime, counteracting domain coarsening due to thermodynamic coupling between active matter concentration and #nematic order. As a result, domains reach a characteristic size that decreases with increasing activity.

This regime is one part of the #PhaseDiagram we mapped out. Along with our other findings, you can read all about it here!

What is the scientific word for a Fluid or semi-Fluid that holds its bead when put on a surface. Think ketchup. You could write with it, and the ketchup would mostly hold its location and height.

Is this viscosity also? Or is there a word for the vertical strength of a liquid/gel
