Field-theoretic derivation of bubble-wall force

Journal of High Energy Physics, 2021
We derive a general quantum field theoretic formula for the force acting on expanding bubbles of a first order phase transition in the early Universe setting.

Obtaining Maxwell's equations heuristically

, 2012
Starting from the experimental fact that a moving charge experiences the Lorentz force and applying the fundamental principles of simplicity (first order derivatives only) and linearity (superposition principle), we show that the structure of the ...

Coupled Chemical and Mechanical Control of the Pore Size in Carbon Honeycomb Membranes for Water Desalination

Advanced Materials Interfaces, EarlyView.
ABSTRACT The advancement of 3D carbon nanostructures for next‐generation desalination membranes is hindered by limited control of the pore size to ensure effective salt rejection. Chemical functionalization and mechanical modification are known approaches to address the problem, while the combined effect of the two approaches remains unexplored.

Impact of magnetostriction mechanism on frequency manipulation ultrasonic steering in electromagnetic acoustic transducers

Electronics Letters
In this paper, the impact of the magnetostriction mechanism is considered as the focus. An axisymmetric FEM model of the spiral‐coil electromagnetic acoustic transducers (EMAT) is established to conduct the simulation.

A quaternionic unification of electromagnetism and hydrodynamics

, 2010
We have derived energy conservation equations from the quaternionic Newton's law that is compatible with Lorentz transformation. This Newton's law yields directly the Euler equation and other equations governing the fluid motion. With this formalism, the

Gravitation: Global Formulation and Quantum Effects [PDF]

, 2003
A nonintegrable phase-factor global approach to gravitation is developed by using the similarity of teleparallel gravity with electromagnetism. The phase shifts of both the COW and the gravitational Aharonov-Bohm effects are obtained.

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors

Advanced Materials Interfaces, EarlyView.
The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.

Changes in Photospheric Lorentz Force in Eruptive and Confined Solar Flares

The Astrophysical Journal
Solar flares are known to leave imprints on the magnetic field in the photosphere, often manifested as an abrupt and permanent change in the downward-directed Lorentz force in localized areas inside the active region.

Hall Coefficient of Equilibrium Supercurrents Flowing inside Superconductors

, 2009
We study augmented quasiclassical equations of superconductivity with the Lorentz force, which is missing from the standard Ginzburg-Landau and Eilenberger equations. It is shown that the magnetic Lorentz force on equilibrium supercurrents induces finite
