Background: Hemoglobinopathies are the commonest genetic defect worldwide (7% of the world's population has at least one hemoglobin mutation). Although prenatal screening for hemoglobinopathies is not obligatory during pregnancy in Italy, it is offered to women by the Italian National Health Service in the pre-conception phase. The screening of newborns is a valid alternative, and has been adopted in various European countries, albeit in a piecemeal fashion.

Methods: This retrospective study was conducted on the behalf of the Italian Society of Pediatric Nephrology (SINePe) in 17 Italian pediatric EDs in March and April 2020, comparing them with data from the same periods in 2018 and 2019.
In this work, the infiltration of TiN powders by electrophoretic deposition (EPD) in aqueous media was considered as alternative method to reduce the size craters and the roughness of commercial porous Ti substrates. Ti substrates can be used as suitable supports for the deposition of dense hydrogen separation TiNx-based membranes by physical vapor deposition (PVD) techniques. The influence of various EPD deposition parameters on surface morphology and roughness of TiN-infiltrated substrates were investigated in order to optimize their surface properties.

Currently, nitride-based thin films are considered promising membranes for hydrogen. The first series of TiN/Si test samples were developed while changing the reactive gas percentage (N%) during the process.
