Mycobacterium smegmatis (Ms), with its short generation time and low biosafety requirements, serves as an appropriate model to study Mycobacteria in general and is useful for assays of anti-tuberculosis agents. Recently, ceramic materials have been used in biomedical applications as a substrate. The aim of this work was to evaluate the ability of growth by Ms over supports prepared with a ceramic mixture. The supports were synthetized from hydroxyapatite (HA) and In2TiO5. SEM, EDS and XRD were used for analyze its final chemical composition. The increase of the oxygen concentration it is attributed to photocatalytic effect promoted by the sunlight exposure of supports immersed on MDB 7H9. The ceramic mixture, was responsible of the oxygen increase and, consequently, of the increase of eight times on the minimal inhibitory concentration in rezasurine assays on microplate. The use of the ceramic support showed the Ms growth 24 h before respect to the control without support.
Aluminum matrix composite materials (AMCs) are widely used in components for the aerospace and automotive industries [1]. These compounds show a high strength/weight ratio, good mechanical properties and greater durability due to the addition of particles as reinforcements [1,2]. The present work will focus on the study of the reinforcement of AA 6061 alloy with particles of CaSiO3 (wollastonite). Powder metallurgy is widely used to control the dispersion of particles in AMCs [3,4]. The present work aims to study the influence of different contents of CaSiO3 on the microstructure of the alloy matrix and the effect of the powder metallurgy technique by optical microscopy (OM), scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM / EDS).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
