or impaired catalytic activity. When the scientists corrected a loss-of-function PKC mutation in the genome of a colon cancer cell line
and high catalytic activity that make them excellent candidates for industrial catalysts. Now, researchers in Singapore have developed a simple chemical process to grow uniform pentagonal nanorods composed of gold and copper.
Next, the team evaluated the catalytic activity of these goldopper nanorods in a carbonitrogen-bond-forming reactionhe direct alkylation of an amine using an alcohol."
"Our heterogeneous catalyst showed higher catalytic activity toward the C coupling reaction and better recyclability compared to commercially available catalysts,
excellent catalytic activity; and reusability in carbon-carbon and carbon-nitrogen bond-forming reactions with 100%conversion efficiency.
"The research results demonstrated that this new technology shows high stability, dispersibility, catalytic activity, and reusability in water, which other existing metal nanoparticles on solid supports have not been able to do,
"This novel material significantly enhanced catalytic activity for the oxygen reduction reaction--the splitting of an O2 molecule into two oxygen ions--that is critical to fuel cells and potentially other electrochemical applications.
The Pt3ni nanoframe catalysts achieved a more than 36-fold and 22-fold enhancement in two different measures of catalytic activity (mass and specific activities, respectively) for the oxygen reduction reaction in comparison to state-of-the-art
and catalytic activity that is made possible by the nanowire/bacteria hybrid technology. With this approach the Berkeley team achieved a solar energy conversion efficiency of up to 0. 38-percent for about 200 hours under simulated sunlight,

Arizona State university and Xiamen University in China have developed a new fabrication method that minimizes the need for expensive metal to induce catalytic activity in fuel cell applications.
porous structures that induce catalytic activity within and outside the nanocages. The layers are grown on templates of palladium nanocrystal templates.
which could affect the economic viability of the fuel cells. e can get the catalytic activity we need by using only a small fraction of the platinum that had been required before,
because we don want to waste any material in the bulk that does not contribute to the catalytic activity.
so their catalytic activity can be engineered to fit different types of reactions. He further stated that hollow platinum structures have been produced previously,
As both the inner and outer layers of the porous nanocages play a vital role in catalytic activity,
which further leads to modifications in the catalytic activity. The research is focused mainly on reducing the expense of cathodes used in fuel cells that power homes and automobiles.
the researchers observed that there is a fall in the catalytic activity by slightly more than one-third after 10,000 operating cycles.
none of the alternatives has yielded the equivalent amount of catalytic activity in an equally small mass until now. f you took all of the platinum that we have available today
such as increasing catalytic activity, reducing cathode flooding and eliminating the need for external humidification equipment. However, at higher temperatures, current electrolyte that is used in PEMFC dehydrate (becomes very dry),
suggesting that both modifications played a role in the enhanced catalytic activity under visible light. Eventually, the team hopes to use their findings to help break down BPA and other contaminants in water supplies."
which inhibits catalytic activity. Materials that repel water, as shown at right, where droplets form sharp,
steep boundaries, are more conducive to catalytic activity, as shown by the reactions among small orange molecules.
for applications requiring high catalytic activity, the team found, a key requirement is that the surface be hydrophobic,
it has a higher affinity for catalytic activity. Shao-Horn notes that this is an initial finding,
