Mechanical Properties and Corrosion Resistance of Thin Ceria and Phosphate Mono- and Multilayers Deposited on Technically Pure Al 1050.

Calcium phosphates are often used for biomedical applications. Hydroxyapatite, for example, has a wide range of applications because it mimics the mineral component of natural bone. Widespread interest in the catalytic properties of ceria is due to its use in automotive catalytic converters.

Investigation of mechanical and physicochemical properties of clinically retrieved titanium-niobium orthodontic archwires.

Purpose: Most of the orthodontic archwires used in the clinical practice nowadays contain nickel (Ni), however, many patients, especially kids, are allergic to Ni. One possible Ni-free alternative is the Titanium-Niobium (Ti-Nb) archwire. Unfortunately, there is not enough information about its mechanical properties in the literature, especially after clinical usage.
