The use of a novel three-dimensional graphene structure allows circumventing the limitations two-dimensional nature and its application in hydrogen absorption. Here we investigate hydrogen-bonding on monolayer conformally grown via epitaxial growth method (0001) face porousified 4H-SiC wafer. Hydrogen absorption is studied Thermal Desorption Spectroscopy (TDS), exposing samples to either atomic...

objectives: the aim of the study was to compare the effect of fifth and seventh generation bonding agent on sealant success. materials and methods: sixty-four school children aged six to nine years received sealants in four permanent molars in a split mouth design, such that each patient received sealant in the first permanent molar with fifth generation bonding agent in one arch and seventh ge...

multiple adhesive coating is a controversial topic, especially in primary dentition that should be clarified. we evaluated the effect of multiple consecutive adhesive resin coatings on the microshear bond strength (μsbs) of composite resin to primary tooth dentin utilizing a filled (adper single bond plus) and an unfilled (adper single bond) adhesive resin.thirty extracted primary canines were ...

this in-vitro study sought to assess the push-out bond strength of a total etch and 2 self-etch bonding systems to intracanal dentin of primary anterior teeth (pat).thirty-six primary anterior teeth were randomly divided into 3 groups of 5(th) generation (single bond 2), 6(th) generation (clearfil se) and 7(th) generation (single bond universal) bonding agents. the canal orifice was restored wi...

in the present work, an extensive theoretical calculation study on histidine-histidine dipeptide in gas phase is done by using dft method with gaussian 98 program. through investigations on the molecular geometries of this molecule it is found that there is six rings in the molecules not two rings. the presence of four intramolecular hydrogen bonds is responsible for the formation of additional...

conclusions a small diaphragmatic tear due to blunt trauma to the abdomen is difficult to diagnosis in acute settings due to ragged margins and possibly no herniated contents and usually present with a delayed complication. therefore a careful examination of the entire traumatized area is the best approach in treating delayed presentation of traumatic diaphragmatic hernia prior to development o...
