Sentences with phrase «surface hydroxyls»

During the experiments and computational study, the researchers looked at how water, surface hydroxyls and the metal - support interface interacted during carbon monoxide oxidation over a gold - titania catalyst.

Not exact matches

The hydrogen - bearing material is volatile (easily vaporized), and may be in the form of water molecules (two hydrogen atoms bound to an oxygen atom) or hydroxyl molecules (an oxygen bound to a hydrogen) that are loosely bound to the lunar surface.

The ribozyme active site also makes tertiary contacts with a tripod of 2» - hydroxyls on the minor groove surface of the splice site helix.

Alternating layers of polymer and nanoparticles of silica (which have hydroxyl groups bound to their surface) form a superhydrophilic coating that can be applied to glass and other materials.

In the latter case, the researchers realized that hydroxyl behaves as a sort of anchor, setting the template for a tidy hexameric ring of water molecules attracted to the metal's surface.

Mavrikakis, assistant scientist Guowen Peng and Ph.D. student Carrie Farberow, along with researchers at Aarhus University in Denmark and Lund University in Sweden, investigated how hydroxyls affect water molecules around them, and how that differs from water molecules contacting a pristine metal oxide surface.

I've been experimenting with T10 dextran coated iron oxide nanoparticles, obviously not the same as fullerenes, but still a very interesting tool, I've been testing if the coating is giving the particle antioxidant abilities because of it's the (basically) indigestable sugar chains (glucose) creating a high surface area which are largely made from hydroxyl groups, I hypothesised this act's as a «sink» for reactive oxygen species converting them to water.

MagSi - Direct beads attach to the starting molecule via strong coordinate bonds between the surface of the bead and any electron donating group on the user's molecule (carboxyl, amide, 1 °, 2 °, 3 ° amine, hydroxyl, phosphate, halogen etc).

Additional output from the ACCMIP runs will include concentration / mass of radiatively active species, aerosol optical properties, and radiative forcings (clear and all sky) as well as important parameters that do not directly influence climate such as hydroxyl, chemical reaction rates, deposition rates, emission rates, surface pollutants and diagnostics of tracer transport.
