Effect of Beverages and Mouthwashes on the Hardness of Polymers Used in Intraoral Prostheses
(Wiley-Blackwell, 2014-10-01)
PurposeThe mechanical properties of acrylic resins used in intraoral prostheses may be altered by frequent exposure to liquids such as beverages and mouthwashes. This study aimed to evaluate the effect of thermocycling and ...
Determination of film thickness through simulation of vickers hardness testing
(Materials Research, 2017-05)
In recent decades, changes in the surface properties of materials have been used to improve their tribology characteristics. However, this improvement depends on the process, treatment time and, essentially, the thickness ...
Effect of addition of pigments and opacifier on the hardness, absorption, solubility and surface degradation of facial silicone after artificial ageing
(Elsevier B.V., 2012-08-01)
The physical properties of silicone prostheses can be influenced by materials used for aesthetic detailing. The purpose of this study was to investigate the effect of two pigments and one opacifier on hardness, absorption, ...

Relation between magnetic Barkhausen noise and hardness for jominy quench tests in SAE 4140 and 6150 steels
(New York, 2013-01-30)
he nondestructive Magnetic Barkhausen Noise (MBN) technique was applied for the evaluation of SAE 4140 and SAE 6150 steels after a Jominy end-quench test. Microstructures were also characterized by SEM (Scanning Electron ...
STUDY OF THE EFFECT OF TEMPERATURE ON THE HARDNESS, GRAIN SIZE, AND YIELD IN ELECTRODEPOSITION OF CHROMIUM ON 1045 STEEL
(Sociedad Chilena de Química, 2008)
The Fukui potential is a measure of the chemical hardness
(2011)
The chemical hardness is, after the chemical potential, the most important concept in describing the chemical reactivity of atoms and molecules. Recently, we showed that the Fukui potential at the nucleus of an atom is ...
Plasma focus based flash hard X-ray source in the 100 keV region with reproducible spectrum
(Elsevier Science, 2010-10)
A pulsed hard X-ray source with shot to shot reproducible spectrum, based on a 4.7 kJ small-chamber Mather-type plasma focus device, is presented. The hard X-ray output spectrum was measured in a single shot basis by ...
