Peptide programming of supramolecular vinylidene fluoride ferroelectric phases
$29.99 / 30 days
www.nature.com/articles/s41586-024-08041-4Abstract
Ferroelectric structures have spontaneous macroscopic polarization that can be inverted using external electric fields and have potential applications including information storage, energy transduction, ultralow-power nanoelectronics1,2 and biomedical devices3. These functions would benefit from nanoscale control of ferroelectric structure, the ability to switch polarization with lower applied fields (low coercive field) and biocompatibility. Soft ferroelectrics based on poly(vinylidene fluoride) (PVDF)4,5,6 have a thermodynamically unstable ferroelectric phase in the homopolymer, complex semi-crystalline structures, and high coercive fields. Here we report on ferroelectric materials formed by water-soluble molecules containing only six VDF repeating units covalently conjugated to a tetrapeptide, with the propensity to assemble into the β-sheet structures that are ubiquitous in proteins. This led to the discovery of ribbon-shaped ferroelectric supramolecular assemblies that are thermodynamically stable with their long axes parallel to both the preferred hydrogen-bonding direction of β-sheets and the bistable polar axes of VDF hexamers. Relative to a commonly used ferroelectric copolymer, the biomolecular assemblies exhibit a coercive field that is two orders of magnitude lower, as the result of supramolecular dynamics, and a similar level of remnant polarization, despite having a peptide content of 49 wt%. Furthermore, the Curie temperature of the assemblies is about 40 °C higher than that of a copolymer containing a similar amount of VDF. This supramolecular system was created using a biologically inspired strategy that is attractive in terms of sustainability and that could lead to new functions for soft ferroelectrics.

Yes … and it doesn’t know when it is on time.

i agree with you that we are much better than LLMs in the fact we can verify our errors (and we can do much more things LLMs don’t do).
Still i am happy to have access to their vast memory and i know where they fail most of times so i can work with them in a productive way.
The day we provide them (or DNNs) with “Will” is i think when they will become (more) dangerous. - Comment on LLMs develop their own understanding of reality as their language abilities improve 2 months ago:
Science cannot say much about what it is to think since it doesn’t understand the brain well enough … and the day we can fully explained it, we will also be able to replicated it on computers.

i feel that many of us, when confronted to this, are doing like Z.B. (president of the Galaxy) in The hitchhiker guide… when he says :
… “whenever I stop and think why did I want to do something? – how did I work out how to do it? – I get a very strong desire to just to stop thinking about it” …

Kamala would still be great like now but on the other side it sure would improve things if they had a candidate which was not a rapist, felon and worse.

Silica gel is extremely expensive, so, if you have this much money, install a pole with a big sprinkler on top outside.

- Comment on Lemmy votes ARE public, should they be anonymous? 2 months ago:
No I was not sarcastic. So now i am trying to read your paper and i think that it is above my knowledge level.
As a layman i had the intuition that instead of having two accounts as i proposed for voting and commenting which was implemented by @rimu, we might have had something like blockchain or filecoin or some coin that would represent voting power and that would be based on our commenting value… so that coin would have been an intermediary to make voting anonymous.
Finally i know enough about science that i know that i don’t know much.

@rimu@piefed.social did great on my simple idea and this is very nice to know. He did not implement his other idea of having a pool of available robots that would vote one time each for each one vote of each one user(s) … also I thought it might be implemented in the frontend but he did implement it in the backend.
i did not say before but i was also thinking about complex mechanisms involving some kind of coin that would represent voting power that could be spent when voting or accumulated maybe with some loss of value with time … but then i read about the many research paper that were published about such things … in conclusion i believe we will see many other iterations of such social media.
thanks for the feedback 😌
