(2014-01-01)
Arboreal ants of the genus Myrmelachista, which have ecologically important relationships with different vegetable species, are found exclusively in the Neotropical region. These ant species are difficult to identify, and ...
Zirconato de cálcio: um estudo para aplicação como sensor de umidade relativa
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2013-04-19)
In this work, it was used the Polymeric Precursors method (PPM). It started from a previous solution of metal cations in different concentrations, using citric acid as chelating agent and ethylene glycol as esterifying and ...
Influence of CAD-CAM milling on the flexural strength of Y-TZP dental ceramics
(2019-06-01)
In this work, the influence of milling strategy and cutter wear on the flexural strength of sintered Y-TZP ceramics machined in a CAD-CAM system, was investigated. Pre-sintered Y-TZP blocks were machined with tungsten ...

Biocompatibilidade in vitro em amostras densas e porosas de titânio-35nióbio submetidas a tratamento biomimético
(Universidade Estadual Paulista (Unesp), 2011-07-29)
Titânio (Ti) é um dos melhores biomateriais para a confecção de implantes cirúrgicos, porém, estudos com novas ligas de Ti e variações da topografia visam otimizar os resultados da osseointegração. O objetivo deste estudo ...
PZT ceramics obtained from mechanochemically synthesized powders
(Kluwer Academic Publ, 2003-01-01)
PZT ceramics were obtained from the mechanochemically synthesized powders. Milling and sintering conditions were optimized based on results of density measurements, as well as on microstructural and electrical characterization. ...
