Molecular dynamics simulations of the isotopic effect on nanoscale friction
(2021-07-08)
Computer simulations are becoming increasingly useful for studying friction, enabling the application of controlled conditions, uncoupling mechanisms, and set-ups that are not usually achievable in physical experiments, ...
Nitretação a plasma de aço inoxidável austenítico sinterizado AISI 316L com adição de ítria
(2023-03-29)
In this work, plasma nitriding of sintered 316L austenitic stainless steel was performed, with and without addition of yttria. The hollow cathode type configuration was used in the nitriding reactor. Initially varying the ...
Efeito do teor de ferro na síntese de vitrocerâmicos de basalto
(2020-11-03)
Basalts, which cover about 70% of the Earth's surface, are igneous rocks originated from the cooling and solidification of magma on the Earth's surface. When the magma is cooled rapidly, it forms a glass. When cooled slowly, ...
Efeitos relativísticos, equação de estado e transições de fase induzidas por altas pressões no aureto de césio
(2023-09-13)
Cesium auride (CsAu) is an intriguing compound formed by two metals that exhibits properties of both an ionic and a semiconductor salt. In this study, we employ computer simulations to explore the influence of relativistic ...
