Evaluation of Rare-earth Sesquioxides Nanoparticles as a Bottom-up Strategy Toward the Formation of Functional Structures
Autor: Silas Cardoso dos Santos, Orlando Rodrigues Junior, Leticia Lucente Campos
Publikováno v: Current Applied Materials. 1
Background: The strategy to form functional structures based on powder technology relies on the concept of nanoparticles characteristics. Rare-earth sesquioxides (RE2O3; RE as Y, Tm, Eu) exhibit remarkable properties, and their fields of application

Evaluation of 3D printing filaments for construction of a pediatric phantom for dosimetry in CBCT
Autor: Orlando Rodrigues Junior, Ladyjane Pereira Fontes Assemany, Ezequiel da Silva, Maria da Penha Albuquerque Potiens
Publikováno v: Radiation Physics and Chemistry. 167:108227
Cone-beam computed tomography (CBCT) has been widely used in orthodontics, due to the ability to provide visualization of mineralized tissues in high definition and consequently the identification and delimitation of three-dimensional irregularities.
