The effect of the plasma response on peeling–ballooning modes during edge localized modes mitigated by resonant magnetic perturbations

open access: yesNuclear Fusion, 2023
The effects of resonant magnetic perturbation (RMP) fields on peeling–ballooning (P–B) modes are studied with the experimental equilibria of EAST based on the four-field model in BOUT++ code.

Localization of Energy in General Relativity [PDF]

open access: yes, 1995
In the framework of the teleparallel equivalent of general relativity the energy density of asymptoticaly flat gravitational fields can be naturally and unambiguously defined.

Sensitivity and effectivity of Kim’s novel electro-thermodynamic cycle over Olsen cycle on waste heat recovering with high fluctuating temperature source using lead-free pyroelectric Ba(Zr0.1Ti0.9)O3

open access: yesAIP Advances, 2021
A novel electro-thermodynamic cycle with a higher waste heat recovery efficiency than the conventional Olsen cycle was introduced by Kim et al. in 2015. Thus, in the present study, the importance of the temperature factors was investigated, revealing the

The nuclear energy density functional formalism [PDF]

open access: yes, 2013
The present document focuses on the theoretical foundations of the nuclear energy density functional (EDF) method. As such, it does not aim at reviewing the status of the field, at covering all possible ramifications of the approach or at presenting ...

The Energy Density in the Casimir Effect [PDF]

open access: yes, 2002
We compute the expectations of the squares of the electric and magnetic fields in the vacuum region outside a half-space filled with a uniform dispersive dielectric.

Electromagnetic energy density in hyperbolic metamaterials

open access: yesScientific Reports, 2022
AbstractWe present the theory of electromagnetic energy propagation through a dispersive and absorbing hyperbolic metamaterial (HMM). In this way, the permittivity tensor components of HMM (especially, nanowire HMM) may appear to be hopeless, but as a non-trivial step, we find that they can be cast into more transparent forms.

Cosmological Evolution with Negative Energy Densities

open access: yesAstrophysics, 2022
For general number of spatial dimensions we investigate the cosmological dynamics driven by a cosmological constant and by a source with barotropic equation of state. It is assumed that for both those sources the energy density can be either positive or negative. Exact solutions of the cosmological equations are provided for flat models.

Monitoring BaTiO3 sintering using nanosecond pulsed electric field

open access: yesScience and Technology of Advanced Materials: Methods
Sintering is a critical process in ceramic fabrication, conducted in electric furnaces. However, the conditions within these furnaces remain largely unobservable, necessitating the development of real-time monitoring techniques.

High deuteron and neutron yields from the interaction of a petawatt laser with a cryogenic deuterium jet

open access: yesFrontiers in Physics, 2023
A compact high-flux, short-pulse neutron source would have applications from nuclear astrophysics to cancer therapy. Laser-driven neutron sources can achieve fluxes much higher than spallation and reactor neutron sources by reducing the volume and time ...

Pressure Driven Alkane Dehydrogenation by Palladium Metal

open access: yesAdvanced Materials Interfaces, 2023
Dehydrogenation of alkanes is of increasing importance in fulfilling global demand for olefins and offers a potential source of carbon‐neutral hydrogen as a co‐product. Currently commercial dehydrogenation processes occur at high‐temperatures (500–900 °C)
