Plasma membrane rupture was long thought to be driven by osmotic pressure, but it has recently been shown to be in many cases an active process, mediated by the protein ninjurin-18 (NINJ1). Here we resolve the structure of NINJ1 and the mechanism by which it ruptures membranes. Super-resolution microscopy reveals that NINJ1 clusters into structurally diverse assemblies in the membranes of dying cells, in particular large, filamentous assemblies with branched morphology. A cryo-electron microscopy structure of NINJ1 filaments shows a tightly packed fence-like array of transmembrane α-helices. Filament directionality and stability is defined by two amphipathic α-helices that interlink adjacent filament subunits. The NINJ1 filament features a hydrophilic side and a hydrophobic side, and molecular dynamics simulations show that it can stably cap membrane edges. The function of the resulting supramolecular arrangement was validated by site-directed mutagenesis. Our data thus suggest that, during lytic cell death, the extracellular α-helices of NINJ1 insert into the plasma membrane to polymerize NINJ1 monomers into amphipathic filaments that rupture the plasma membrane. The membrane protein NINJ1 is therefore an interactive component of the eukaryotic cell membrane that functions as an in-built breaking point in response to activation of cell death.","lang":"eng"}],"type":"journal_article"},{"month":"07","publication_identifier":{"eissn":["1864-564X"],"issn":["1864-5631"]},"oa":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000985051300001"],"pmid":["36970847"]},"isi":1,"quality_controlled":"1","doi":"10.1002/cssc.202300128","language":[{"iso":"eng"}],"article_number":"e202300128","file_date_updated":"2023-11-14T11:27:16Z","year":"2023","acknowledgement":"The authors (N.L.F and R.B.J) would like to acknowledge the funding contributions of Shell and the EPRSC via I–Case studentships (grants no.

Tris(4-aminophenyl)amine was found to be the strongest candidate. Solubility and initial electrochemical performance were promising; however, polymerisation was observed during electrochemical cycling leading to rapid capacity fade prescribed to a loss of accessible active material and the limitation of ion transport processes within the cell. A mixed electrolyte system of H3PO4 and HCl was found to inhibit polymerisation producing oligomers that consumed less active material reducing rates of degradation in the redox flow battery. Under these conditions Coulombic efficiency improved by over 4 %, the maximum number of cycles more than quadrupled and an additional theoretical capacity of 20 % was accessed. This paper is, to our knowledge, the first example of triarylamines as catholytes in all-aqueous redox flow batteries and emphasises the impact supporting electrolytes can have on electrochemical performance.","lang":"eng"}],"issue":"13","_id":"13041","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","title":"Triarylamines as catholytes in aqueous organic redox flow batteries","ddc":["540"],"intvolume":" 16","file":[{"file_id":"14532","relation":"main_file","success":1,"checksum":"efa0713289995af83a2147b3e8e1d6a6","date_updated":"2023-11-14T11:27:16Z","date_created":"2023-11-14T11:27:16Z","access_level":"open_access","file_name":"2023_ChemSusChem_Farag.pdf","creator":"dernst","file_size":1168683,"content_type":"application/pdf"}],"oa_version":"Published Version"},{"author":[{"full_name":"Hernandez, J.-A.","first_name":"J.-A.","last_name":"Hernandez"},{"orcid":"0000-0002-1838-2129","id":"201939f4-803f-11ed-ab7e-d8da4bd1517f","last_name":"Bethkenhagen","first_name":"Mandy","full_name":"Bethkenhagen, Mandy"},{"full_name":"Ninet, S.","last_name":"Ninet","first_name":"S."},{"first_name":"M.","last_name":"French","full_name":"French, M."},{"full_name":"Benuzzi-Mounaix, A.","last_name":"Benuzzi-Mounaix","first_name":"A."},{"full_name":"Datchi, F.","first_name":"F.","last_name":"Datchi"},{"full_name":"Guarguaglini, M.","last_name":"Guarguaglini","first_name":"M."},{"full_name":"Lefevre, F.","last_name":"Lefevre","first_name":"F."},{"full_name":"Occelli, F.","last_name":"Occelli","first_name":"F."},{"last_name":"Redmer","first_name":"R.","full_name":"Redmer, R."},{"first_name":"T.","last_name":"Vinci","full_name":"Vinci, T."},{"last_name":"Ravasio","first_name":"A.","full_name":"Ravasio, A."}],"related_material":{"link":[{"url":"10.1038/s41567-023-02130-3","relation":"erratum"}]},"date_created":"2023-06-04T22:01:02Z","date_updated":"2023-11-14T12:58:31Z","volume":19,"acknowledgement":"We acknowledge the crucial contribution of the LULI2000 laser and support teams to the success of the experiments.

This behaviour potentially plays a role in explaining the origin of the multipolar magnetic fields of Uranus and Neptune, whose mantles are thought to result from a mixture of H2O, NH3 and CH4 ices. Determining the stability domain, melting curve and electrical conductivity of these superionic phases is therefore crucial for modelling planetary interiors and dynamos. Here we report the melting curve of superionic ammonia up to 300 GPa from laser-driven shock compression of pre-compressed samples and atomistic calculations. We show that ammonia melts at lower temperatures than water above 100 GPa and that fluid ammonia’s electrical conductivity exceeds that of water at conditions predicted by hot, super-adiabatic models for Uranus and Neptune, and enhances the conductivity in their fluid water-rich dynamo layers."}],"type":"journal_article","date_published":"2023-09-01T00:00:00Z","publication":"Nature Physics","citation":{"short":"J.-A.

The interplay of DW order with superfluidity can lead to complex scenarios that pose a great challenge to theoretical analysis. In the past decades, tunable quantum Fermi gases have served as model systems for exploring the physics of strongly interacting fermions, including most notably magnetic ordering1, pairing and superfluidity2, and the crossover from a Bardeen–Cooper–Schrieffer superfluid to a Bose–Einstein condensate3. Here, we realize a Fermi gas featuring both strong, tunable contact interactions and photon-mediated, spatially structured long-range interactions in a transversely driven high-finesse optical cavity. Above a critical long-range interaction strength, DW order is stabilized in the system, which we identify via its superradiant light-scattering properties. We quantitatively measure the variation of the onset of DW order as the contact interaction is varied across the Bardeen–Cooper–Schrieffer superfluid and Bose–Einstein condensate crossover, in qualitative agreement with a mean-field theory. The atomic DW susceptibility varies over an order of magnitude upon tuning the strength and the sign of the long-range interactions below the self-ordering threshold, demonstrating independent and simultaneous control over the contact and long-range interactions. Therefore, our experimental setup provides a fully tunable and microscopically controllable platform for the experimental study of the interplay of superfluidity and DW order."}]},{"issue":"4","abstract":[{"lang":"eng","text":"This paper establishes new connections between many-body quantum systems, One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport (OT), by interpreting the problem of computing the ground-state energy of a finite-dimensional composite quantum system at positive temperature as a non-commutative entropy regularized Optimal Transport problem. We develop a new approach to fully characterize the dual-primal solutions in such non-commutative setting. The mathematical formalism is particularly relevant in quantum chemistry: numerical realizations of the many-electron ground-state energy can be computed via a non-commutative version of Sinkhorn algorithm. Our approach allows to prove convergence and robustness of this algorithm, which, to our best knowledge, were unknown even in the two marginal case. Our methods are based on a priori estimates in the dual problem, which we believe to be of independent interest. Finally, the above results are extended in 1RDMFT setting, where bosonic or fermionic symmetry conditions are enforced on the problem."}],"type":"journal_article","oa_version":"Preprint","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"12911","intvolume":" 285","title":"A non-commutative entropic optimal transport approach to quantum composite systems at positive temperature","status":"public","article_processing_charge":"No","day":"15","scopus_import":"1","date_published":"2023-08-15T00:00:00Z","citation":{"apa":"Feliciangeli, D., Gerolin, A., & Portinale, L.
