Author(s): Sergio Díaz-Tendero, Noah Frese, Debadarshini Mishra, Aaron C. LaForge, Nora Berrah, and Fernando Martín We present a joint theoretical and experimental investigation of the isomerization dynamics of doubly ionized acetonitrile $[{\mathrm{H}}_{3}\mathrm{C}─\mathrm{C}≡\mathrm{N}{]}^{2+}$ in the gas phase. Molecular dynamics simulations show that the dication retains its linear geometry for a few hundred… [Phys. Rev. Lett. 136, 048002...

Author(s): Klavs Hansen, Kaveh Najafian, Bertil Dynefors, Mauritz J. Ryding, Einar Uggerud, Siegfried Kollotzek, Johannes Reichegger, Olga V. Lushchikova, and Paul Scheier The evaporative decay of mixed heavy and light water clusters was measured. The branching ratios of the three isotopologue molecules scale with the deuterium fraction from cluster size $N=9$ and up, including across the well-known shell closing at $N=21$, and are consistent...

Author(s): Weiqiang Tang, Jinwen Liu, Katharina Doblhoff-Dier, and Jun Huang Fundamental understanding of electrical double layers (EDL) has been gleaned mostly on ideally planar electrodes, while realistic electrodes usually exhibit surface roughness on multiple scales. The influence of mesoscopic roughness (1–10 nm) is elusive, representing a cutting-edge challenge to theo… [Phys. Rev. Lett. 136, 038001] Published Wed Jan 21, 2026

Author(s): M. Milani, E. Cavalletti, V. Ruzzi, A. Martinelli, P. Dieudonné-George, C. Ligoure, T. Phou, L. Cipelletti, and L. Ramos We exploit the controlled drying of millimeter-sized gel beads to investigate the isotropic compression of colloidal fractal gels. Using a custom dynamic light scattering setup, we demonstrate that stresses imposed by drying on the bead surface propagate homogeneously throughout the gel volume, indu… [Phys. Rev...

Author(s): Ji-Hui Pei (裴继辉) and Christian Maes Can activity be transmitted from smaller to larger scales? We report on such a transfer from a homogeneous active medium to a Newtonian spherical probe. The active medium consists of faster and dilute self-propelled particles, modeled as run-and-tumble particles in 1D or as active Brownian particles… [Phys. Rev.

Author(s): Shunsuke Ichii, Tetsuhiro S. Hatakeyama, and Kunihiko Kaneko Enhanced enzyme diffusion (EED), in which the diffusion coefficient of an enzyme transiently increases during catalysis, has been extensively reported experimentally, although its existence remains under debate. In this Letter, we investigate what macroscopic consequences would arise if EED exists. … [Phys. Rev. Lett. 136, 038401] Published Wed Jan 21, 2026
