Our article on the #mechanics of "active" entropic biopolymer networks [possibly including #actomyosin, this is debated experimentally] is now published in J Elas.

Compared to enthalpic models, we're able to go right from the #thermodynamics of an unbiased #molecularMotor activity (in the spirit of the model by #JacquesProst for #myosin) at the molecular scale to a network-scale model in a closed form.

And we derive a method for solving quite easily the (usually tough) #viscoelastic #liquid model that we obtain, using #deformationGradientDecomposition.

doi.org/10.1007/s10659-024-101
(I share a paywall-free link to my followers below, but it's also on arXiv: arxiv.org/abs/2405.07287 and on my webpage liphy-annuaire.univ-grenoble-a)

The microstructure is made of entropic chains which form a network but can transiently unbind, relax and rebind. Together with affine deformations in the velocity graident, this gives a viscoelastic liquid rheology. What we add is the flux $j_a$ created by molecular motors.
Deformation gradient decomposition in action: finding the dynamics of a tangentially contractile sphere bound elastically to a fixed sphere.

#ferriccarbon a version of #carbon transfer is what I'm up against. I found an interesting forum regarding it with lots of input from #sandyking I thought he was a she for the longest time. I figured she had been gone for a long time because of how legendary the guy is. He's literally on every #alternativephotography forum that has any relevance. Anyway, I only know how to fail at #carbontransfer right now, but have you ever noticed how beautiful #tissue can look?

Yesterday I made the most beautiful #tissue for #CarbonTransfer. I spent some time #ballmilling 300mesh graphite mixed with some random carbon I had made some time ago. After 12 hours of milling I got the stuff out into a pickle jar. It's basically diy India ink of the highest quality. It made the best tissue I had ever made. But it failed completely. I think I found several issues that will make a successful print next time. 1) the PH was 9, it's supposed to be 4. 2)temp was 40. It's 32!!!!
