Sentences with phrase «metal oxide molecules»

Unfortunately, lower temperatures means the metal oxide molecules fail to line up well in the crystals.

Not exact matches

This serves as the perfect glue for attaching the oil - loving molecules, which are deposited in a second step; they hold onto the metal oxide layer with one end and reach out to grab oil molecules with the other.

Hwang also considered metal oxide frameworks that trap carbon dioxide molecules, but they had the unfortunate side effect of capturing the desired methane as well and they are far too expensive to make for this application.

The sunscreen chemicals that absorb the sun's dangerous ultraviolet radiation are typically organic molecules (as opposed to the metal oxides that block the sun's rays in sunblock).

A typical MOF consists of a metal oxide center surrounded by organic molecules that form a highly porous three - dimensional crystal framework.

Even molecules like nitric oxide behave like magnetic impurities: when located between metal electrodes they give rise to a Kondo effect.

Other researchers might also look at whether other molecules exhibit similar behavior when they come into contact with metal oxides, he adds.

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.

These include electronic - skin coatings that can detect blood oxygen levels, contact lenses made from metal - oxide thin films that can detect glucose levels in tears and flexible integrated sensor arrays based on plastic and silicon integrated circuits that can detect molecules like glucose in sweat.

Supporting Role: In these catalysts, the oxides are merely a surface on which the precious metals sit while the metals break and form bonds in other molecules, such as those found in automobile exhaust.

Researchers Dr. James Gerken and Dr. Shannon Stahl at CME used two metal - free catalysts, an organic nitroxyl (R2NO) molecule and inorganic nitrogen oxide (NOx) source, to promote oxygen reduction.

A team of Argonne researchers discovered a way to attach oil - loving molecules to polyurethane foam — the same foam commonly used in furniture and insulation — by «priming» it with a metal oxide «glue.»

The spectrum of a class M star contains lines from oxide molecules (in the visible spectrum, especially TiO) and all neutral metals, but absorption lines of hydrogen are usually absent.
