The calculated electron density distribution for orpiment, As(2)S(3), reveals that As-S, S-S, and As-As bond paths are associated with the experimental interlayer directed bonded interactions detected in a combined infrared and Raman study. The successful modeling of the infrared- and Raman-determined interlayer bonded interactions together with bond paths and the structuralization of a variety...

The performance and lifetime of the flexible asphalt pavement are mainly dependent on interfacial bond strength between layer courses. To enhance layers, adhesive materials, such as tack coats, used. coat itself is a bituminous material, which applied an existing relatively non-absorbent surface to ensure strong old newly paved layer. primary objective this study was evaluate effects various ty...

We demonstrate a process to selective laser melt metal alloy directly onto graphite. The heat transfer applications of features printed annealed pyrolytic graphite are compelling, as has the second highest in-plane thermal conductivity (>1500 W/m-K at room temperature) any bulk material. While bonding alloys commonly used in melting (SLM) with is relatively weak, proper interlayer material dras...

statement of the problem: various methods such as light emitting diode (led) have been used to enhance the polymerization of resin-based orthodontic adhesives. there is a lack of information on the advantages and disadvantages of different light curing systems. purpose: the aim of this study was to compare the effect of led and halogen light curing systems on the shear bond strength of orthodon...

OBJECTIVES The aim of this study was to test the hypothesis that the bonding ability of antibacterial bonding system to primary dentin was not different from the parental material which did not contain any antibacterial component. METHODS Extracted human non-carious primary molars were ground to expose the coronal dentin, and then randomly divided into two experimental groups: treatment with ...
