Dynamics of an initially spherical bubble rising in quiescent liquid
Nature Communications, 2015 The beauty and complexity of the shapes and dynamics of bubbles rising in liquid have fascinated scientists for centuries. Here we perform simulations on an initially spherical bubble starting from rest.

Nanoscale Bubble Domains and Topological Transitions in Ultrathin Ferroelectric Films
Advanced Materials, 2017 Observation of a new type of nanoscale ferroelectric domains, termed as “bubble domains”—laterally confined spheroids of sub‐10 nm size with local dipoles self‐aligned in a direction opposite to the macroscopic polarization of a surrounding ferroelectric

Vertically neutral collapse of a pulsating bubble at the corner of a free surface and a rigid wall
Journal of Fluid Mechanics, 2023 Vertically neutral collapse of a pulsating bubble occurs when the boundaries above or below the bubble balance the buoyancy effect over a pulsation. In this study, the vertically neutral collapse of a bubble near a vertical rigid wall below the free ...
