Liquid/surface interaction during pool boiling of DI-water on nanocoated heating surfaces
(2018-11-01)
This study focuses on the effect of the nanostructured heating surface on the heat transfer coefficient (HTC) considering the nanofluid concentration used for coating surfaces and the heating surface morphology. Copper ...
In vitro evaluation of surface roughness of 4 resin composites after the toothbrushing process and methods to recover superficial smoothness.
(2007-05-01)
OBJECTIVE: This study evaluated the efficiency of repolishing, sealing with surface sealant, and the joining of both in decreasing the surface roughness of resin-based composites after a toothbrushing process. METHOD AND ...
Implementation of diverse non-centrosymmetric layer concepts for tuning the interface activity of a magnesium alloy
(2016-01-01)
Magnesium and its alloys are the lightest metallic materials used for structural applications. Tuning the surface functionalization of magnesium alloys may contribute to increasing their durability. Dry or wet processes ...
Histometric analysis and topographic characterization of cp Ti implants with surfaces modified by laser with and without silica deposition
(Wiley-Blackwell, 2014-11-01)
Biologic behavior of the bone tissue around implants with four different surfaces was evaluated. The surfaces were: modified by laser (LS); modified by laser with sodium silicate deposition (SS); and commercially available ...
Factors affecting the strength of denture repairs: Topics of interest
(2007-07-01)
Fracture of dentures is a common clinical finding in daily prosthodontic practice, resulting in great inconvenience to both patient and dentist. A satisfactory repair should be cost-effective, simple to perform, and quick; ...
Aging effect of atmospheric air on zirconia surfaces treated by nonthermal plasma
(2015-01-01)
Purpose: The purpose of this study was twofold: 1) to characterize the zirconia (Y-TZP) surfaces through scanning electronic microscopy associated with energy-dispersive spectroscopy and atomic force microscopy after the ...
Feature extraction using frequency spectrum and time domain analysis of vibration signals to monitoring advanced ceramic in grinding process
(Inst Engineering Technology-iet, 2019-01-01)
New alternatives for monitoring the ceramic grinding process have been studied. Monitoring vibration signals is one of the most successful methods because some characteristics that describe the behaviour and influence of ...
Immobilisation of apatite on Ti30Ta alloy surface by electrospinning of PCL
(Ice Publishing, 2017-06-01)
Surface modifications of titanium alloy have been extensively researched for the purpose of increasing the biocompatibility of medical implants. In this study, a Ti30Ta alloy surface was modified by functionalisation with ...
The use of elevation map histograms for topographic heterogeneity analysis
(2013-07-01)
Surface defects are extremely important in mechanical characterization of several different materials. Therefore, the analysis of surface finishing is essential for a further simulation of surface mechanical properties in ...
Surface finishing of glass ionomer
(1997-12-01)
Purpose: To evaluate the surface roughness and staining of a glass ionomer cement when subjected to different finishing procedures. Materials and Methods: Sixty-four discs of Chem-Fil II glass ionomer cement were submitted ...
