Tomorrow starts the “Festival della Scienza” in Genova! This is a perfect opportunity to explore the wonders of science! Maybe another year we should be there with the @phyphoxorg app, making science accessible to everyone. Don’t miss it! #FestivalScienza #Genova2024

Die Vorstandsvorsitzende des FZJ, Astrid Lambrecht, wurde in das Direktorium des @KarlspreisAC gewählt. Das Direktorium hat eine herausgehobene Rolle, denn es wählt die Preisträger dieser viel beachteten europäischen Auszeichnung aus.

Something for the weekend: there is a first camera support in the phyphox beta on Android. See phyphox.org/news/camera-supp…

Version 1.1.16 brings image support in experiment configurations to phyphox. There are a few more additions to the file format that you might put to good use. Full list of changes (and fixes): phyphox.org/wiki/index.php/V…

1/8 We have put together a manuscript about the use of pencil and paper to make simple electronic experiments and sensors. The aim is to use this material for practicum for high schoolers and undergraduates. Link👇 arxiv.org/abs/2405.07646
Thread to explain it here👇
Great to see our work on #NegativeElectronicCompressibility in charge islands in #TwistedBilayerGraphene being picked as PRB Editor's Suggestion! Thanks for all the support: @ML4Q_cluster, @2dmp_spp2244, @fz_juelich, @RWTH!

ALT EDITORS' SUGGESTION Negative electronic compressibility in charge islands in twisted bilayer graphene By exploiting naturally occurring charge islands due to twist angle variations in twisted bilayer graphene, the authors measure here how strongly charge carriers interact. They discover negative capacitance contributions, which are indicative of correlation effects near band insulators at full filling on both flat and remote sides, and at integer partial fillings. The correlation strength remains constant across all bands, unaffected by a magnetic field. The reported results point to a possible Wigner crystal phase as the underlying mechanism. Robin J. Dolleman et al. Phys. Rev. B 109, 155430 (2024)
When a layer of twisted bilayer graphene is aligned with hexagonal boron nitride, additional single-particle band gaps appear! See our recent paper in Phys. Rev. B for more details! Thanks for support: @ML4Q_cluster, @2dmp_spp2244, @fz_juelich, @RWTH,

Kicking a smartphone with the fingers and wait until it stops due to friction. Measure the acceleration with @phyphoxorg and integrate it twice in time. Beautiful exercise, rich of insights: kinematics, dynamics, energy, work, numerical integration, uncertainty.
Something very useful for the lab...:

Sometimes you need to stand on top of things to look at your work in a different way
Yesterday, ML4Q members convened atop Cologne's rooftop for a reflective session, recapping the past few months and anticipating exciting ML4Q2

With yr13s today, dropping magnets through a coil - Faraday's Law.
@phyphoxorg timed experiment makes it easy to catch the moment of dropping.
Refresh rate of the Bluetooth voltmeter high enough to see the shape change from magnet approaching and leaving coil
