Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(2009-06-01)
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...

Sunlight active g-C3N4-based Mn+ (M[dbnd]Cu, Ni, Zn, Mn) – promoted catalysts: Sharing of nitrogen atoms as a door for optimizing photo-activity
(Elsevier, 2019-12)
In this work we analyze the photocatalytic performance of Mn+ (M[dbnd]Cu, Ni, Zn, Mn) - g-C3N4 materials in toluene photo-oxidation under UV and Sunlight-type illumination conditions. The characterization of the solids ...

The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...
