I am happy to share that the last work from my PhD time is out: Universal Time and Length Scales of Polar Active Polymer Melts https://t.co/LfyXfptl6e

[Mattia Ubertini @MattiaUbertini]

Most interestingly, we have found that the chain dynamics is not controlled by polymer entanglements but only on the strength of the active forces.

@AlexanderRKlotz Have a look at this: https://t.co/1Ohwc6cmpB

@AlexanderRKlotz Thank you! And I did my best for pushing you 😂

@Dmichiel1 Here I worked at higher valency. But yes for your point, in the previous works where I was varying the polymer's size I got a percolating network anytime the linking degree was between 2 and 3.

The last work of my PhD is out. Here, we investigate how geometric constraints (slit-confinement) can be exploited for the synthesis of self-assembled topological polymer networks (Olympic networks).

@Dmichiel1 Hi Davide, thanks for pointing this out. I actually missed your estimate on kdna elasticity. I will definitely have a look and try to compare the two.

[Mattia Ubertini @MattiaUbertini]

In particular, we show that slit-confinement can be exploited for the synthesis of networks that act softer under mechanical stress.

New preprint out https://t.co/qXR9ecozDw
In this work we perform topological analysis of melts of topologically complex rings and we show how to recover the entanglement of the system from its topology.

[Mattia Ubertini @MattiaUbertini]

From the analysis of 1) single-ring (knots), 2) couples of rings (two-chain links), 3) triplets of rings (three-chain links), we show that two-chain links capture almost the full entanglement of the system with three-chain links adding minor corrections.

Finally out!

New paper! Monte Carlo simulations show that ring polymers are double-folded above the entanglement length, while threadings are localized on smaller scales, reconciling different theories https://t.co/9rJStKNFTi @MacroJrnls_ACS @univienna @Sissaschool #topology #rings
