Sentences with phrase «synthetic catalyst»

Using a natural catalyst from bacteria for inspiration, researchers have now developed the fastest synthetic catalyst for hydrogen production — producing 45 million molecules per second.

The new synthetic catalyst is both fast and efficient.

With this insight into how nature fixes nitrogen, Holland and his colleagues hope to design synthetic catalysts that turn nitrogen into ammonia, the main fertilizer produced in the natural system.

Refining the scaffolding in synthetic catalysts could increase the catalyst's speed and efficiency.

Why It Matters: «Overall, our research shows that proper bridging of synthetic catalysts and features from natural enzymes can help us develop novel sets of materials that can have activity far beyond any natural enzymes,» said Shaw.

This step is just one part of a series of reactions to split water and make hydrogen gas, but the researchers say the result shows they can learn from nature how to control those reactions to make durable synthetic catalysts for energy storage, such as in fuel cells.

In order for aspartic acid to become the neurotoxic sweetener aspartame, it must undergo various synthetic catalyst processes, and then must be isolated, given a solvent, filtered and distilled.

Researchers report this week that they have created a synthetic catalyst that works the same way as enzymes do.

Even though the synthetic catalyst yields the same weapons - degradation product as the enzyme, it does so by a means that is much less dependent on the exact structure and composition of the chemical weapon target.

After three rounds of mutations, the protein could bond silicon to carbon 15 times more efficiently than any synthetic catalyst.

Results: By grafting features analogous to those in Mother Nature's catalysts onto a synthetic catalyst, scientists at Pacific Northwest National Laboratory created a hydrogen production catalyst that is 40 % faster than the unmodified catalyst.

The scientists want to design a synthetic catalyst that can reach enzymatic speeds, so they examined how they could add features from the outer sphere of enzymes to synthetic catalysts.

One thing they noticed was that the synthetic catalyst produced hydrogen faster in a viscous liquid as opposed to a free - flowing liquid.

Methods: In an enzyme or a synthetic catalyst, swift movement of the protons from the metal where the reaction takes place to the outside of the molecule is essential for the reversible reaction between molecular hydrogen fuel and electricity.

Working in the Center for Molecular Electrocatalysis, a DOE Energy Frontier Research Center back in 2011, they made a synthetic catalyst that was 10 times faster than the natural one.

«This synthetic catalyst is a clear indication of the intricate interplay between the different layers of a catalyst and begins to mimic the complexity observed in certain enzymes,» said Dr. Wendy Shaw, who led the research.

In addition, the synthetic catalyst can operate at conditions that would disable its natural counterpart.

The highlights, «Fuel Cells: Bio-inspired design» and «Platinum - Free Hydrogen Oxidation,» describe the team's work on integrating a synthetic catalyst into proton exchange membrane fuel cells.
