(Elsevier B.V., 2009-09-01)
Objective: This study evaluated the clinical effectiveness of two exposure times of microwave irradiation on the disinfection of complete dentures.Methods: Biofilm samples were collected from dentures of 30 patients, who ...
Disinfection of Bovine Enamel by Microwave Irradiation: Effect on the Surface Microhardness and Demineralization/Remineralization Processes
Enamel specimens need to be disinfected before being used in intraoral appliances and the disinfection method must not affect the integrity of the tooth. This study evaluated the effectiveness of microwave bovine enamel ...
Synthesis of wurtzite ZnS nanoparticles using the microwave assisted solvothermal method
In this article, we report the development of an efficient and rapid microwave assisted solvothermal (MAS) method to prepare wurtzite ZnS nanoparticles at 413 K using different precursors. The materials obtained were ...
Influence of microwave energy on structural and photoluminescent behavior of CaTiO3 powders
(Elsevier B.V., 2008-08-01)
Calcium titanate, CaTiO3 powders were prepared by the polymeric precursor method and annealed at different temperatures for 2 h in a conventional furnace and for 30 min on an adapted microwave oven. The effect of microwave ...
