    Casting Homogeneity of Scaled-Up Multiprincipal Component Alloys by Gbenga. J. Adeyemi, Claire Utton, Yunus Azakli, Russell Goodall

    Published 2025-01-01
    “…Studies on these materials are largely conducted on small samples, but, for many practical applications, larger-scale processing would be needed. The processing of metallic parts of high dimensionality conventionally begins with casting, but an increase in the scale of the melt increases the potential for effects dependent on segregation, diffusion and thermal transport. …”

    Turbulent Transport Characteristics of the Particles within Pulsar Wind Nebulae 3C58 and G54.1+0.3 by Fang-Wu Lu, Bo-Tao Zhu, Wen Hu, Li Zhang

    Published 2024-01-01
    “…Our application of the model to the multiband emission from 3C58 and G54.1+0.3 reveals the following. (1) The energy and spatial diffusion coefficients seem to follow quasi-linear distributions in the Kolmogorov-type turbulence, but consistent with nonlinear distributions at low energies in the Kraichnan-type turbulence due to the effects of the turbulent scattering. (2) The stochastic acceleration and spatial diffusion processes may play a role in modifying the electron spectrum in the Kolmogorov-type turbulence, whereas in the Kraichnan-type turbulence the energy exchange between the turbulent waves and particles is more efficient, resulting in more significant effects of the stochastic acceleration and spatial diffusion processes on the electron spectrum at the low energies of E _e ≲ 1 TeV. (3) At the high energies of E _e ≳ 1 TeV, the diffusion transport appears to be less effective for the evolution of the particles within 3C58 and G54.1+0.3 because the synchrotron radiative cooling process dominates over the particle transport. …”
