Direct colour printing on zirconia using 222 nm UV-C photons.

Objectives: To proof the feasibility of direct colour printing on 3Y-TZP using 222 nm UV-C through investigating the degree and durability of the colour changes, and testifying whether surface, mechanical and biological properties are influenced by the treatment.

Methods: 222 nm UV-C light (Irradiance: 1.870 mW/cm) was used to treat 3Y-TZP for durations from 15 min to 24 h.

The mechanical, wear, antibacterial properties and biocompatibility of injectable restorative materials under wet challenge.

Objectives: To evaluate the mechanical, wear, antibacterial properties, and biocompatibility of injectable composite materials.

Methods: Two injectable composite resins (GU and BI), one flowable composite resin (FS), and one flowable compomer (DF), in A2 shade, were tested. Mechanical properties were tested via three-point bending test immediately after preparation and after 1-day, 7-day, 14-day, and 30-day water storage.

Construction of Z-scheme CdS/Ag/TiO NTs photocatalysts for photocatalytic dye degradation and hydrogen evolution.

The ternary CdS/Ag/TiO NTs photocatalysts with indirect Z-scheme heterojunctions were synthesized by the photoreduction deposition of Ag and successive ionic layer adsorption and reaction (SILAR) of CdS on TiO nanotube arrays (TiO NTs). The elemental composition, microstructure, photoresponse and photoelectrochemical property of the photocatalyst were systematically characterized. The results proved that compared with binary heterojunction, the light absorption range of the ternary CdS/Ag/TiO NTs photocatalyst was significantly extended, and the photoelectron transportation efficiency was improved.
