A Review of Novel Heat Transfer Materials and Fluids for Aerospace Applications
Nobrega, Glauco Tapijara Vallicelli; Cardoso, Beatriz D.; Souza, Reinaldo Rodrigues de; Pereira, José Eduardo; Pontes, Pedro; Catarino, Susana O.The issue of thermal control for space missions has been critical since the early space missions in the late 1950s. The demands in such environments are heightened, characterized by significant temperature variations and the need to manage substantial densities of heat. The current work offers a comprehensive survey of the innovative materials and thermal fluids employed in the aerospace technological area. In ...
Light transmittance through resin-matrix composite onlays adhered to resin-matr...
Fidalgo-Pereira, Rita; Catarino, Susana O.; Carvalho, Óscar; Veiga, Nélio; Torres, Orlanda; Braem, Annabel; Souza, Júlio C. M.OBJECTIVE: The aim of this study was to evaluate the influence of the thickness of resin-matrix composite blocks manufactured by CAD-CAM on the light transmittance towards different resin-matrix cements or flowable composites. METHODS: Sixty specimens of resin-matrix composite CAD-CAM blocks reinforced with 89 wt% inorganic fillers were cross-sectioned with 2 or 3 mm thicknesses. The specimens were conditioned ...

A scoping review on the polymerization of resin-matrix cements used in restorat...
Fidalgo-Pereira, Rita; Torres, Orlanda; Carvalho, Óscar; Silva, Filipe S.; Catarino, Susana O.; Özcan, Mutlu; Souza, Júlio C. M.In dentistry, clinicians mainly use dual-cured or light-cured resin-matrix cements to achieve a proper polymerization of the organic matrix leading to enhanced physical properties of the cement. However, several parameters can affect the polymerization of resin-matrix cements. The main aim of the present study was to perform a scoping review on the degree of conversion (DC) of the organic matrix, the polymeriza...
Effect of inorganic fillers on the light transmission through traditional or fl...
Fidalgo-Pereira, Rita; Carvalho, Óscar; Catarino, Susana O.; Henriques, Bruno; Torres, Orlanda; Braem, Annabel; Souza, Júlio C. M.Objectives: The aim of this in vitro study was to evaluate the light transmission through five different resin-matrix composites regarding the inorganic filler content. Methods: Resin-matrix composite disc-shaped specimens were prepared on glass molds. Three traditional resin-matrix composites contained inorganic fillers at 74, 80, and 89 wt. % while two flowable composites revealed 60 and 62.5 wt. % inorganic ...
Blood cells separation and sorting techniques of passive microfluidic devices: ...
Catarino, Susana O.; Rodrigues, Raquel O.; Pinho, Diana; Miranda, João M.; Minas, Graça; Lima, Rui Alberto Madeira MacedoSince the first microfluidic device was developed more than three decades ago, microfluidics is seen as a technology that exhibits unique features to provide a significant change in the way that modern biology is performed. Blood and blood cells are recognized as important biomarkers of many diseases. Taken advantage of microfluidics assets, changes on blood cell physicochemical properties can be used for fast ...
