Density of Lipschitz functions in energy
Calculus of Variations and Partial Differential Equations, 2022 AbstractIn this paper, we show that the density in energy of Lipschitz functions in a Sobolev space$$N^{1,p}(X)$$N1,p(X)holds for all$$p\in [1,\infty )$$p∈[1,∞)whenever the spaceXis complete and separable and the measure is Radon and positive and finite on balls. Emphatically,$$p=1$$p=1is allowed.

Cosmological Evolution with Negative Energy Densities
Astrophysics, 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
Science and Technology of Advanced Materials: MethodsSintering 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.

RELATIVISTIC NUCLEAR ENERGY DENSITY FUNCTIONALS [PDF]
International Journal of Modern Physics E, 2010 A class of relativistic nuclear energy density functionals is explored, in which only nucleon degrees of freedom are explicitly used in the construction of effective interaction terms. Short-distance correlations, as well as intermediate and long-range dynamics, are encoded in the nucleon-density dependence of the strength functionals of an effective ...

Pressure Driven Alkane Dehydrogenation by Palladium Metal
Advanced 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)

Frontiers 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 ...

ENERGY–MOMENTUM DENSITY OF GRAVITATIONAL WAVES [PDF]
International Journal of Modern Physics A, 2008 In this paper, we elaborate the problem of energy–momentum in general relativity by energy–momentum prescriptions theory. Our aim is to calculate energy and momentum densities for the general form of gravitational waves. In this connection, we have extended the previous works by using the prescriptions of Bergmann and Tolman.

Nanotwin hardening in a cubic chromium oxide thin film
APL Materials, 2015 NaCl-type (B1) chromium oxide (CrO) has been expected to have a high hardness value and does not exist as an equilibrium phase. We report a B1-based Cr0.67O thin film with a thickness of 144 nm prepared by pulsed laser deposition as an epitaxial thin ...
