Shock wave attenuation in a high-entropy alloy with pre-existing dislocation network
Published 2025-01-01“…However, the in-depth understanding of dynamic deformation mechanisms remains limited due to technological constraints in real-time detection of microstructural evolution at the atomic level. In present work, non-equilibrium molecular dynamics (NEMD) simulations were performed to study the shock response of FeCoNiCrCu HEAs with pre-existing dislocation network. …”

Mechanisms of RCD-1 pore formation and membrane bending
Published 2025-01-01“…Here, we demonstrate that RCD-1 binds acidic lipid membranes, forms pores, and induces membrane bending. Using atomic force microscopy (AFM) and AlphaFold, we show that RCD-1-1 and RCD-1-2 form heterodimers that further self-assemble into ~14.5 nm-wide transmembrane pores (~10 heterodimers). …”

Macroscopic perspective on phase transition behavior of natural single-crystal graphite under different pressure environments
Published 2025-01-01“…Here, we report on the pressure-induced phase transition behavior of natural single-crystal graphite under three distinct pressure-transmitting media from a macroscopic perspective using in situ two-dimensional Raman spectroscopy, scanning electron microscopy, and atomic force microscopy. The surface evolution process of graphite before and after the phase transition is captured, revealing that pressure-induced surface textures can impede the continuity of the phase transition process across the entire single crystal. …”

Matematical modeling of the process of enlarging the austenitic grain during high-temperature heating of alloy structural steel
Published 2019-10-01“…A phenomenological model describing the mechanism of formation and growth of austenitic grains in steels under heating at different speeds is developed.It is concluded that the slow heating of steels in the interval of phase a®g transformation contributes to the formation of a complex of small austenite grains separated by high angle boundaries with adsorbed on them by impurity atoms, which ensures higher resistance grain structure to coalescence and reduce the rate of migration of the boundaries during prolonged hightemperature austenization.…”
