Formation of Optical Bullets in Laser-Driven Plasma Bubble Accelerators [PDF]

, 2010
Electron density bubbles-wake structures generated in plasma of density (n) over bar (e) similar to 10(19) cm(-3) by the light pressure of intense ultrashort laser pulses-are shown to reshape weak copropagating probe pulses into optical "bullets.'' The ...

Geomagnetic conjugacy of plasma bubbles extending to mid-latitudes during a geomagnetic storm on March 1, 2013

Earth, Planets and Space, 2022
This study, for the first time, reports the geomagnetically conjugate structure of a plasma bubble extending to the mid-latitudes and the asymmetrical structure of the decay of the plasma bubble during a geomagnetic storm.

Liquid-phase methane bubble plasma discharge for heavy oil processing: Insights into free radicals-induced hydrogenation

, 2021
Hydrogenation, an alternative to conventional cracking, is poised to revolutionize heavy oil upgrading by raising the hydrogen-to-carbon ratio at lower process pressures and temperatures.

The impact of gravity waves rising from convection in the lower atmosphere on the generation and nonlinear evolution of equatorial bubble [PDF]

Annales Geophysicae, 2009
The nonlinear evolution of equatorial F-region plasma bubbles under varying ambient ionospheric conditions and gravity wave seeding perturbations in the bottomside F-layer is studied.

A Statistical Analysis of Plasma Bubbles Observed by Swarm Constellation during Different Types of Geomagnetic Storms

Universe, 2021
Based on the observations of Ionospheric Bubble Index (IBI) data from the Swarm mission, the characteristics of plasma bubbles are investigated during different types of geomagnetic storms recorded from 2014 to 2020.

Concurrent study of bottomside spread F and plasma bubble events in the equatorial ionosphere during solar maximum using digisonde and ROCSAT-1 [PDF]

Annales Geophysicae, 2005
Data from the Jicamarca digisonde and the ROCSAT-1 satellite are employed to study the equatorial ionosphere on the west side of South America during April 1999-March 2000 for the concurrent bottomside spread F (BSSF) and plasma bubble events.

Drag reduction due to recirculating bubble control using plasma actuator on a squareback model

MATEC Web of Conferences, 2018
Flow control on a squareback object which resembles many engineering related objects is believed to be highly beneficial. One of the flow characteristics behind the object, recirculating bubble, is known to play significant role in pressure distribution.

Numerical simulation of the equatorial plasma bubble: the effect of seeding by the vertical winds and random background noise perturbations

Frontiers in Astronomy and Space Sciences, 2023
A wide variety of small-amplitude waves widely exist in the ionosphere and have significant effects on the evolution of equatorial plasma bubbles. In this paper, we simulated equatorial plasma bubbles (EPB) seeded by vertical neutral wind perturbations ...

New sonochemiluminescence involving solvated electron in Ce(III)/Ce(IV) solutions

Ultrasonics Sonochemistry, 2021
The moving single-bubble sonoluminescence of Ce3+ in water and ethylene glycol solutions of CeCl3 and (NH4)2Ce(NO3)6 was studied. As found, a significant part of intensity of the luminescence (100% with cerium concentration less than 10–4 M) is due to ...
