Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.

Módulo elástico como ferramenta para avaliação da hidratação da magnésia e dos processamento de concretos refratários Elastic modulus as a tool for magnesia hydration and refractory castables processing evaluation

open access: yesCerâmica, 2012
Considerando-se as dificuldades para a utilização de MgO em concretos refratários, técnicas anti-hidratação têm sido propostas com o objetivo de minimizar os efeitos deletérios causados pela reação da magnésia com a água. Em paralelo, surge a necessidade

Deformable Eutectic Alloy With Near‐Theoretical Yield Strength via Hierarchical Nanoscale Multiphases and Sessile Defects

open access: yesAdvanced Science, EarlyView.
A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Hidratação e desidratação de óxido de magnésio em concretos refratários Magnesia sinter hydration-dehydration behavior in refractory castables

open access: yesCerâmica, 2008
Óxido de magnésio (MgO) rapidamente reage com água quando exposto a umidade ou durante a mistura de concretos refratários, gerando uma camada de hidróxido de magnésio, Mg(OH)2, na superfície das partículas. Durante a secagem desses materiais entre 350 ºC
