Laboratory investigation of diamond grinding and grooving textures on concrete pavement surfaces
Polishing of surface texture warrants a rehabilitative treatment that addresses just the surface for safe riding experience. The rate of polishing was found to be proportional to the hardness of the aggregates used in the concrete mixture. The lack of hard aggregates is prompting a surface texture …

Analysis of potential applications for the templated dewetting of metal thin films
… as thin film dewetting, can be initiated by grooving at grain boundaries or triple junctions. Dewetting of thin films on topographically modified substrates has many interesting characteristics. It is a novel self-assembly process for the formation of well-ordered nanoparticle arrays with …

The effects of capillarity on photonic crystal selective emitters
… diffusion, vapor transport, and grain boundary grooving, this thesis seeks to understand its consequences and attempts to pinpoint methodologies that may prevent it. It was shown that while grain boundary grooves have a negligible effect on photonic crystal structures, vapor transport and …

Theoretische Untersuchung der thermischen Stabilität und morphologischer Umwandlungen in nanoskaligen Multischichten
… der Multischicht. "Grain boundary grooving" wird als ein Mechanismus für die Bildung eines Schichtdurchbruchs an Korngrenzen vorgeschlagen. Durchbrochen Schichten ziehen sich getrieben durch Kapillarkräfte zurück. An den Endstellen bilden sich Wulste aus. Je nach …

Chemical treatment of corroding steel reinforcement after removal of chloride contaminated concrete
… was removed to the rebar level through a grooving process. The grooves were chemically treated through solution pondings and backfilling with treated mortar. Seventeen treatments and combination of treatments were evaluated including corrosion inhibitors, polymer sealers, and a possible …

Virus elimination from Actinidia germplasm
… B (AcVB), Alfalfa mosaic virus (AMV), Apple stem grooving virus (ASGV), Actinidia virus X (AVX), Citrus leaf blotch-like virus (CLBV-a), and Cucumber mosaic virus CMV). Also, the phylogenetic relationship of AMV isolated from Actinidia was compared to other extant isolates. It was found that …

Pavement Friction Management (PFM) - A Step Toward Zero Fatalities
… evaluates the potential of grinding and grooving technique to restore friction properties of the pavement. Once sleek spots are identified through pavement friction management program, this technique can be used to restore the friction without compromising the roadway smoothness.

Transmission and routing of optical signals in on-chip waveguides for silicon microphotonics
… the top surface roughness due to grain boundary grooving. compared to a Si/Si02 waveguide. Compact high An routing devices such as round bends, Y-splitters, and Multi-Mode Interference (MMI) splitters are fabricated and tested. We show that single-mode waveguide bends exhibit μm size bending with …

Abrasion-corrosion of cast CoCrMo in simulated hip joint environments
… abrasion-corrosion wear mechanisms (rolling or grooving abrasion) and the average wear-induced corrosion currents show a linear correlation with wear rates for 4 ?m and 1 ?m abrasives. For low volume concentration (< 0.03 vol%) slurries containing bovine serum, organo-metallic conglomerates have …
