The purpose of this study was to evaluate the surface hardness of a resin composite (TPH) polymerized with and without the use of a transparent light-curing cone. Twenty composite blocks were made on a Teflon mold with cylindrical holes of 3 mm depth and 6 mm radius, and were light cured following different procedures. Group 1: Ten samples were pressed with a glass slide and light cured for two...
Nanoindentation tests were performed on nanostructured transparent magnesium aluminate (MgAl2O4) ceramics to determine their mechanical properties. These tests were carried out on samples at different applied loads ranging from 300 to 9,000 μN. The elastic recovery for nanostructured transparent MgAl2O4 ceramics at different applied loads was derived from the force-depth data. The results revea...
The emerging field of "organic" or "plastic" electronics has brought low-voltage, ultrathin, and energy-efficient lighting and displays to market as organic light-emitting diode (OLED) televisions and displays in cameras and mobile phones. Despite using carbon-based materials as the light-emitting layer, previous efficient organic electronic light-emitting devices have required at least one met...
The development of optically transparent and mechanically flexible electronic circuitry is an essential step in the effort to develop next-generation display technologies, including 'see-through' and conformable products. Nanowire transistors (NWTs) are of particular interest for future display devices because of their high carrier mobilities compared with bulk or thin-film transistors made fro...
Background and purpose: Hypothermia after the birth has serious complications and conventional methods for warming of preterm newborns are insufficient. New guideline of neonatal resuscitation program recommended wrapping of premature newborns in polyethylene bags and because of controversies in use of different transparent membranes in studies the aim of this study is determination of effect o...
