The influence of bearing surfaces on revisions due to dislocations in total hip arthroplasty

open access: yesJournal of Materials Science: Materials in Medicine, 2021
Introduction Recurrent dislocations are still the most frequent reason for revision in total hip arthroplasty (THA). The impact of bearing surfaces on dislocations is still controversial. We hypothesized that: (1) bearing surfaces influence the revisions

Ag-Sensitized Yb3+ Emission in Glass-Ceramics [PDF]

open access: yesMicromachines, 2018
Rare earth doped materials play a very important role in the development of many photonic devices, such as optical amplifiers and lasers, frequency converters, solar concentrators, up to quantum information storage devices. Among the rare earth ions, ytterbium is certainly one of the most frequently investigated and employed.
