Enhancement of Surface Hardness: Boron on Diamond (111)
We have performed ab initio pseudopotential calculations for the diamond (111) surface with nitrogen or boron replacing the surface carbon atoms. Surface boron atoms form planar sp2 bonds with carbon atoms and the compressive stress from the underlying bulk diamond lattice squeezes the B-C bonds significantly. Bulk and shear moduli in the surface region increase substantially, surpassing those ...
متن کاملSolvent-induced crystallization of a polycarbonate surface and texture copying by polydimethylsiloxane for improved surface hydrophobicity
The influence of the immersion period on the crystallization of polycarbonate (PC) was investigated, and the resulting texture configurations of the crystal structures were reconstructed with polydimethylsiloxane (PDMS). Analytical tools, including optical microscopy, scanning electron microscopy, atomic force microscopy, X-ray diffraction, the sessile drop technique, Fourier transform infrared...

متن کاملComparative Evaluation of Surface Hardness of Different Resin-Modified Glass Ionomers and a Compomer
Introdouction: Due to the practical problems and time restriction issues in treating dental problems in children, there is a noticeable demand for the application of a convenient handling restorative material with acceptable physical-mechanical properties. The aim of this investigation was to evaluate Vickers microhardness of four tooth-colored restorative materials as a determining mechanical...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
