Room-temperature synthesis of nanocrystalline Ag2S and its nanocomposites with gold

Abstract:
This manuscript demonstrates a room-temperature synthesis for Ag2S nanocrystals and their nanocompsites with Au and the Au could be deposited only at a single site on each Ag2S seed nanocrystal, where in contrast, Ag2S could grow homogeneously on Au seed nanocrystals, resulting in core-shell Au@Ag2S nanoparticles, which still possessed the optical properties of Au nanocrystals; this facile synthesis could be employed towards fabricating a variety of nanocomposites with interesting structures and tailored functionalities.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
Synthesis of carbohydrates
Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...
Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
