Electron-Beam Radiation Effects in Multilayer Structures Grown with the Periodical Deposition of Si and CaF2 on Si(111)

open access: yesMaterials Proceedings, 2023
The formation of CaSi2 films on Si(111) with the molecular-beam epitaxy (MBE) of CaF2 under fast electron-beam irradiation was investigated. The method of a high-planarity CaSi2 film synthesis assisted by electron-beam irradiation was developed.

Effect of remineralisation on the mechanical properties and tribological behaviour of human tooth dentine

open access: yesBiosurface and Biotribology, 2020
With ageing and pathological factors, dentine exposure becomes more and more commonplace in the clinic. The mechanical properties of dentine are far less than those of enamel. Once exposed, dentine exhibits a weak wear-resistance and then results in many
