Bonding orthodontic brackets to ceramic materials is a challenging procedure; femtosecond (FS) laser conditioning could provide improved results, but the ideal settings for effective bracket-zirconia bonding have never been established. This study aimed to analyze the differences in surface roughness and shear bond strength (SBS) produced by different femtosecond laser settings and establish a protocol...
Nowadays, solar volumetric absorbers represent a promising alternative to harvest solar radiation. In these devices, the traditional blackened surface where solar radiation is converted into heat and later transferred to a heat transfer fluid is removed. Then, the solar radiation is trapped by direct volumetric absorption on the carrier fluid itself. This reduces the radiative losses and improves...
Nanocomposites formed by graphene and metal nanoparticles (MNPs) are considered to become one of the most important technological advances due to their wide application range, as it is possible to exploit the combination of electronic characteristics in graphene and optical characteristics in metallic nanostructures [1]. Conventionally, the in-situ synthesis of these kind of nanocomposites is achieved...
