Our work on flexible colloidal rings was published as an Editor's Suggestion in Physical Review E.

These micron-sized colloidal model systems can be studied using light microscopy and can therefore yield valuable insights on the effects of shape changes for their smaller counterparts, such as cyclic polymers.

Thank you Julio Melio, Daniela Kraft and Indrani Chakraborty for the nice collaboration!

The audience of the #SchrödingerLectures is a more wider range of mathematicians and physicists. 👨‍🔬 These kind of lectures are meant to inform non-specialists and students about the latest developments and results in a field of #maths or #physics.

Many #SchrödingerLectures are coming in March 2023, look at these ones for example! 🥳
Save the date and join! 😉 🔖

I'm #newhere, time for an #introduction
💼 I'm a #researcher #AirQuality at the 🇳🇱 Nat. Inst. for #PublicHealth and the #Environment (RIVM). I work on #models like #OPS & #EMEP
🎓 I studied #Physics and wrote a PhD thesis on #colloids in the #SoftMatter group of Daniela Kraft in Leiden
🌳 I like #permaculture and grow #organic food in my #garden, I dream of having my own #FoodForest one day
💡 My hobbies include #reading #jazz #guitar #science #programming #drawing #photography #cloudspotting

#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!

#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…

The #hydrodynamic behaviour of inhomogeneous #activeNematic gels (such as extensile bundles of #cytoskeletal filaments or suspensions of low #ReynoldsNumber swimmers) can be described by the time evolution of three coupled #PDEs.

Standard #ActiveGel #theory concludes, from a #LinearStabilityAnalysis of these equations, that fluctuations in concentration don’t significantly affect emergent #phaseBehaviour. However, this leaves #experimental #observations of visible inhomogeneities in #microtubule–#kinesin mixtures unexplained. As we move away from the passive (quiescent) regime, past the onset of #SpontaneousFlow, and deeper into the active phase, #nonlinearities become more important. What role do concentration inhomogeneities play here?

Alongside #analytic techniques, we used an in-house #MPI-parallel code developed within the #Dedalus #spectral framework to investigate. We predict a #novel regime of #spontaneous #microphaseSeparation into active (nematically ordered) and passive domains. In this regime, active flow arrests macrophase separation, which is itself driven by the thermodynamic coupling between active matter concentration and #nematic order. As a result, domains do not #coarsen past a typical size, which decreases with increasing activity. This regime is one part of the #PhaseDiagram we mapped out.

The #coffee scene in Toluca is really blossoming. It's great to be able to source excellent coffees grown and roasted in the State of #Mexico (some of which have won Cup of Excellence) for our experiments on fracture dynamics at the University of Oregon. Here is one of our workhorses: Amatepec (washed) from El Equimite (Amatepec, State of Mexico, Mexico) roasted by Café Mexiquense.
