Orbiting, colliding and merging droplets on a soap film: toward gravitational analogues

Jean-Paul Martischang, Benjamin Reichert, Germain Rousseaux, Alexis Duchesne, Michael Baudoin

Modern telescopes provide breathtaking images of nebulae, clouds and galaxies shaped by gravity-driven interactions between complex bodies. While such structures are prevalent on an astrophysical scale, they are rarely observed at the human scale. In this letter, we report the observations of the…

Nanoconfinement‐Induced Electrochemical Ion‐Solvent Cointercalation in Pillared Titanate Host Materials

Mennatalla Elmanzalawy, Haohong Song, Maciej Tobis, Robert Leiter, Jaehoon Choi, Hyein Moon, Wan-Yu Tsai, De‐en Jiang, Simon Fleischmann

Abstract Electrochemical ion‐solvent cointercalation reactions are an avenue to reach improved kinetics compared to the corresponding intercalation of desolvated ions. Here, we demonstrate the impact of different structural pillar molecules on the electrochemical Li + intercalation mechanism in…

The ‘very moment’ when UDG recognizes a flipped-out uracil base in dsDNA

Vinnarasi Saravanan, Nessim Raouraoua, Guillaume Brysbaert, Stefano Giordano, Marc F. Lensink, Fabrizio Cleri, Ralf Blossey

Abstract Uracil-DNA glycosylase (UDG) is the first enzyme in the base-excision repair (BER) pathway, acting on uracil bases in DNA. How UDG finds its targets has not been conclusively resolved yet. Based on available structural and other experimental evidence, two possible pathways are under…

Two Types of Bound States in the Continuum in Photonic Comb Structure

Yamina Rezzouk, Soufyane Khattou, Mohamed El Ghafiani, Madiha Amrani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

We propose the design of a comb-shaped cavity that can support several BICs when attached to a waveguide. The cavity consists of a finite comb made of one stub of length placed between two stubs of length via two guides of length and the whole comb is attached vertically along a waveguide. In order…

Topological Interface States in a One-Dimensional Mesoscopic Crystal Using Su-Schrieffer-Heeger Model

Noura Ezzahni, Mohammed Elaouni, Soufyane Khattou, Madiha Amrani, Mohamed El Ghafiani, Yamina Rezzouk, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate the existence of topological interface states between two periodic comb-like mesoscopic crystals with different topological properties based on the Su-Schrieffer-Heeger (SSH) model. This model enables us to predict the existence of topological interface states between two connected…
