Effect of surface roughness on adhesion of graphene membranes

A theoretical model is presented to predict how the surface roughness may affect the adhesion between graphene membranes and their substrates. The bending modulus, which increases drastically from monolayer to multilayered graphene, plays an important role in the transition from conformal to non-conformal morphology of the graphene membranes on a corrugated surface. As such, the measurable adhe...

Scanning tunneling microscopy characterization of the surface morphology of copper films grown on mica and quartz

The morphology of copper films grown on quartz, mica, and Ti/quartz has been investigated by means of scanning tunneling microscopy (STM). Films grown on quartz, both bare and pre-plated with titanium, are characterized by self-affine fractal scaling behavior over the length scale of 10 ̈500 nm, while films grown on mica are not. Annealing of the films to 340 -C reduces the root-mean-square (RMS...

the role of semantic and communicative translation on reading comprehension of scientific texts

the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
