Molecular dynamics simulations of cascade overlap with Void/Helium bubble

open access: yesNuclear Materials and Energy, 2022
When tungsten (W) is used as a plasma-facing material in fusion reactors, it will suffer irradiation from the high-energy neutron and high-flux low-energy helium (He) plasma, affording voids and He bubbles with varying helium-to-vacancy ratios (He/V ...

Microbial decontamination of chicken using atmospheric plasma bubbles

open access: yes, 2020
In this study, we demonstrate that atmospheric air plasma bubbles are an effective, energy-efficient, residue-free alternative to current decontamination techniques.

Numerical simulation of bubble dispersion in turbulent Taylor-Couette flow [PDF]

open access: yes, 2014
We investigate bubble dispersion in turbulent Taylor-Couette flow. The aim of this study is to describe the main mechanisms yielding preferential bubble accumulation in near-wall structures of the flow.

Enhanced D retention in RAFM steel caused by D bubbles formed inside Cr-rich surface layer

open access: yesNuclear Materials and Energy, 2021
To identify the cause for an enhanced D retention in RAFM (reduced-activation ferritic/martensitic) steels with decreasing incident D fluence, ϕD, CLAM steel samples were exposed to D plasma at a low ϕD ∼ 3 × 1023 m−2 in the PISCES-A linear plasma device.

Filamentary Alfvénic structures excited at the edges of equatorial plasma bubbles [PDF]

open access: yesAnnales Geophysicae, 2007
Recent observations performed by the French DEMETER satellite at altitudes of about 710 km suggest that the generation of equatorial plasma bubbles correlates with the presence of filamentary structures of field aligned currents carried by Alfvén ...

Reconstruction of Fermi and eROSITA Bubbles from Magnetized Jet Eruption with Simulations

open access: yesUniverse
The Fermi bubbles and the eROSITA bubbles around the Milky Way Galaxy are speculated to be the aftermaths of past jet eruptions from a supermassive black hole in the galactic center.

Rational asset pricing bubbles [PDF]

open access: yes, 1995
This paper provides a fairly systematic study of general economic conditions under which rational asset pricing bubbles may arise in an intertemporal competitive equilibrium framework.

Overview and summary of the Spread F Experiment (SpreadFEx) [PDF]

open access: yesAnnales Geophysicae, 2009
We provide here an overview of, and a summary of results arising from, an extensive experimental campaign (the Spread F Experiment, or SpreadFEx) performed from September to November 2005, with primary measurements in Brazil.

F-Region electron density irregularities during the development of equatorial plasma bubbles [PDF]

open access: yesGeofísica Internacional, 2000
The height variation of the ionospheric electron density was measured with rocket-borne electron density probes in two campaigns conducted from Alcantara (2.31°S; 35.2°W), Brazil. A Black Brant X sounding rocket was launched on 14 October 1994 at 1955hrs

EXPERIMENTAL DETERMINATION OF TEMPERATURES IN SPARK GENERATED BUBBLES OSCILLATING IN WATER

open access: yesActa Polytechnica, 2017
The surface temperatures of the plasma core in the final stages of the first contraction phase of spark-generated bubbles oscillating under ordinary laboratory conditions in a large expanse of water are determined experimentally.
