Philipp Kurzhals, Geoffroy Kremer, Thomas Jaouen, Christopher W. Nicholson, Rolf Heid, Peter Nagel, John-Paul Castellan, Alexandre Ivanov, Matthias Muntwiler, Maxime Rumo, Bjoern Salzmann, Vladimir N. Strocov, Dmitry Reznik, Claude Monney & Frank Weber Electron-phonon coupling, i.e., the scattering of lattice vibrations by electrons and vice versa, is ubiquitous in solids and can lead to emergent ground states such as superconductivity and charge-density wave order.

Laëtitia Mayen, Nicholai D. Jensen, Maximilien Desbord, Danielle Laurencin, Christel Gervais, Christian Bonhomme, Mark E. Smith, Florence Porcher, Erik Elkaim, Cédric Charvillat, Pierre Gras, Christian Rey, Jérémy Soulié and Christèle Combes, CrystEngComm, 22 (2020) 3130-3143. α-Canaphite (CaNa2P2O7·4H2O) is a layered calcium disodium pyrophosphate tetrahydrate phase of significant geological and potential biological interest.

Jaehong Jeong, Benjamin Lenz, Arsen Gukasov, Xavier Fabrèges, Andrew Sazonov, Vladimir Hutanu, Alex Louat, Dalila Bounoua, Cyril Martins, Silke Biermann, Véronique Brouet, Yvan Sidis, and Philippe Bourges, Phys. Rev. Lett. 125 (2020) 097202. 5d iridium oxides are of huge interest due to the potential for new quantum states driven by strong spin-orbit coupling.

Simeon Minic, Burkhard Annighofer, Arnaud Helary, Djemel Hamdane, Gaston Hui Bon Hoa, Camille Loupiac, Annie Brulet, and Sophie Combet To probe intermediate states during unfolding and oligomerization of proteins remains a major challenge. High pressure (HP) is a powerful tool for studying these problems, revealing subtle structural changes in proteins not accessible by other means of denaturation.

Chang Liu, Wenxian Hu, Hanqiu Jiang, Guoming Liu*, Charles C. Han, Henning Sirringhaus, François Boué, and Dujin Wang The determination of intrinsic chain stiffness of conjugated polymers is challenging, in particular, for scattering techniques because of their strong light absorption and structural instability due to the complicated intra-/intermolecular interactions.

Li Shi, Florent Carn, Arsen Goukassov, Eric Buhler, and François Boué Mixing negatively charged polyelectrolyte (PEL) with positively charged gold nanoparticles (Au NPs) in aqueous solution results in electrostatics complexes of different shapes and compactness. Here, when complexing with a semirigid PEL hyaluronic acid (HA), we obtain crystals made of nanoparticles in a new region of the phase diagram, as evidenced by small-angle Xray scattering (SAXS).
