Solubility, porosity and fluid uptake of calcium silicate-based cements
(Univ Sao Paulo Fac Odontologia Bauru, 2018-01-01)
Objective: To evaluate the absorption/fluid uptake, solubility and porosity of White mineral trioxide aggregate (MTA) Angelus, Biodentine (BIO), and zinc oxide-eugenol (ZOE). Material and Methods: Solubility was evaluated ...
Measurement of Interfacial Porosity at the Acrylic Resin/Denture Tooth Interface
(Wiley-Blackwell, 2010-01-01)
Purpose: Small pores of almost uniform shape and size are common in polymeric materials; however, significant porosity can weaken a denture base resin and promote staining, harboring of organisms such as Candida albicans, ...

Porosity effects on the neutron total cross section of graphite
(Elsevier Science, 2010-01)
For subthermal neutron energies, polycrystalline graphite shows a larger total cross section than predicted by existing theoretical models. In order to investigate the origin of this discrepancy we measured the total cross ...
Effect of Ultrasonic Excitation on the Porosity of Glass Ionomer Cement: A Scanning Electron Microscope Evaluation
(Wiley-liss, 2011-01-01)
Background: Ultrasonic excitation (US) was applied to glass ionomer cement (GIC) during early set time to increase the advantageous properties of this material. Purpose: The aim of this in vitro study was to assess the ...
Effect of addition of surface water treatment sludge to biomass in biochar porosity
(Springer, 2019-12-01)
Samples of pruning sawdust (PS) and water treatment plant (WTP) sludge residue were collected and mixed in proportions of 10 to 80% of WTP sludge in PS, submitted to torrefaction at 260 degrees C, and the resulting biochar ...
