Wave Profile for Anti-force Waves with Maximum Possible Currents [PDF]
, 2015 In the theoretical investigation of the electrical breakdown of a gas, we apply a one-dimensional, steady state, constant velocity, three component fluid model and consider the electrons to be the main element in propagation of the wave. The electron gas

Advanced Engineering Materials, EarlyView.This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Generation of spherically converging shock wave based on shock wave lens [PDF]
Matter and Radiation at ExtremesThe manipulation of intense shock waves to either attenuate or enhance damage has long been a key goal in the domain of impact dynamics. Effective methods for such manipulation, however, remain elusive owing to the wide spectrum and irreversible ...

Prediction of anomalous LA-TA splitting in electrides
Matter and Radiation at Extremes, 2021 Electrides are an emerging class of materials with excess electrons localized in interstices and acting as anionic interstitial quasi-atoms (ISQs). The spatial ion–electron separation means that electrides can be treated physically as ionic crystals, and

Breakdown of Hydrodynamics in a Simple One-Dimensional Fluid
, 2006 We investigate the behavior of a one-dimensional diatomic fluid under a shock wave excitation. We find that the properties of the resulting shock wave are in striking contrast with those predicted by hydrodynamic and kinetic approaches, e.g., the ...

Wave heating from proto-neutron star convection and the core-collapse supernova explosion mechanism [PDF]
, 2020 Our understanding of the core-collapse supernova explosion mechanism is incomplete. While the favoured scenario is delayed revival of the stalled shock by neutrino heating, it is difficult to reliably compute explosion outcomes and energies, which depend
