DOI: 10.1016/j.actamat.2021.116899
Abstract: Abstract Pressure assisted sintering models such as Skorohod-Olevsky's, Abouaf's or Riedel's require the identification of at least four parameters depending on porosity or temperature. The identification of these parameters is difficult at high temperature and… read more here.

DOI: 10.1021/acs.nanolett.1c04708
Abstract: The deep understanding of the sintering mechanism is pivotal to optimizing denser ceramics production. Although several models explain the sintering satisfactorily on the micrometric scale, the extrapolation for nanostructured systems is not trivial. Aiming to… read more here.
