(Cambridge University Press, 2016-11)
A systematic study has been carried out to compare the surface morphology, shell thickness, mechanical properties and binding behavior of melamine formaldehyde icrocapsules of 5 to 30 µm diameter size with various amounts ...
In situ Transmission Electron Microscopy observation of Ag nanocrystal evolution by surfactant free electron-driven synthesis
(2016-03-16)
The study of the interaction of electron irradiation with matter and the response of the material to the passage of electrons is a very challenging problem. However, the growth mechanism observed during nanostructural ...
From tissue retrieval to electron tomography: nanoscale characterization of the interface between bone and bioactive glass
(2021-09-01)
The success of biomaterials for bone regeneration relies on many factors, among which osseointegration plays a key role. Biogran (BG) is a bioactive glass commonly employed as a bone graft in dental procedures. Despite its ...
