New insights into suspended drops: When soft matter meets acoustic levitation

H Chen, Z Hong, D Zang - Droplet, 2024 - Wiley Online Library
Acoustic levitation has developed into a popular but elegant tool for the study of drops as
well as soft matter due to its exceptional levitation capabilities to a variety of liquid samples …

Experimental investigation of a nonspherical water droplet falling in air

M Agrawal, RK Katiyar, B Karri, KC Sahu - Physics of Fluids, 2020 - pubs.aip.org

Activating bubble's escape, coalescence, and departure under an electric field effect

R Yan, R Pham, CL Chen - Langmuir, 2020 - ACS Publications
In this paper, we present the results of applying an electric field to activate bubbles' escape,
coalescence, and departure. A simple electrowetting-on-dielectric device was utilized in this …

Generalization of the Kelvin equation for arbitrarily curved surfaces

DV Svintradze - Physics Letters A, 2020 - Elsevier
Capillary condensation, which takes place in confined geometries, is the first-order vapor-to-
liquid phase transition and is explained by the Kelvin equation, but the equation's …

Application of computer vision techniques for contour detection in underwater wet welding: an exploratory study

JL Ortiz, AM Moreno-Uribe, BR Acevedo… - Journal of Physics …, 2021 - iopscience.iop.org
In underwater wet welding, the process of formation and separation of the bubbles is related
to the stability of the electric arc. For this reason, new methods to characterize these bubbles …

Moving Manifolds and General Relativity

DV Svintradze - arXiv preprint arXiv:2406.08382, 2024 - arxiv.org
We revise general relativity (GR) from the perspective of calculus for moving surfaces (CMS).
While GR is intrinsically constructed in pseudo-Riemannian geometry, a complete …
