Summary
Researchers developed a charge modulation method to stabilize gold (Au) nanoclusters on organic networks. This technique enables controlled growth, leading to a highly effective catalyst for alcohol oxidation.
Area of Science:
- Materials Science
- Catalysis
- Nanotechnology
Background:
- Stabilizing metal nanoclusters is crucial for catalysis.
- Naked metal clusters often lack stability on supports.
- Nanoporous organic materials offer unique support possibilities.
Purpose of the Study:
- To develop a method for stabilizing naked gold (Au) clusters on a nanoporous conjugated organic network.
- To achieve controllable growth of Au nanoclusters.
- To evaluate the catalytic performance of the supported Au nanoclusters.
Main Methods:
- A charge modulation approach was employed to engineer the pore walls of the organic network.
- Controlled growth of Au nanoclusters was achieved by regulating charges on the pore walls.
- The supported Au nanoclusters were tested as catalysts in the aerobic oxidation of alcohols.
Main Results:
- Naked Au clusters were successfully stabilized on the nanoporous organic network.
- Controllable growth of Au nanoclusters was realized through charge engineering.
- The resulting supported catalyst demonstrated excellent performance in the aerobic oxidation of alcohols.
Conclusions:
- Charge modulation is an effective strategy for stabilizing metal nanoclusters on organic supports.
- The developed method allows for controlled synthesis of supported metal catalysts.
- The Au nanocluster catalyst shows great promise for efficient alcohol oxidation reactions.

In some cases, there are seemingly more than one valid Lewis structures for molecules and polyatomic ions. The concept of formal charges can be used to help predict the most appropriate Lewis structure when more than one reasonable structure exists.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

In ordinary chemical reactions, the nucleus — which contains the protons and neutrons of each atom and thus identifies the element — remains unchanged. Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons to form electrically charged particles called...

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

02:18Types of Genetic Transfer Between Organisms
31.0K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.
