The circuit switches are made oftwo connected molecules called bistable rotaxanes.A dumbbell-shaped molecule is threaded through a ring-shaped molecule and,as current is applied to the molecules ...

Molecular clusters are aggregates of molecules that are held together non-covalently, by relatively weak forces. When these clusters are excited, normally one would expect the cluster to simply ...

Threads or ropes can easily be used for braiding, knotting, and weaving. In chemistry, however, processing molecular strands ...

The ultrafast placement of an electron in a polar liquid generates collective molecular vibrations in a spherical nano-volume ...

IBM’s Mohn said the next step could be to build on the technique further and to connect molecules, and also attach molecules to metal as they build nano-scale devices. The company’s ultimate ...

Nanoswitches comprise strands of DNA onto which molecules of interest can be strategically attached at various locations along the strand. Interactions between these molecules, such as successful ...

For example, if you’re making drugs, molecules that are connected properly are medicine. A molecule that is not connected properly is no longer a medicine, and may even be harmful,” said Mark Levin, ...

James Fraser Stoddart created a field of chemistry based on threaded and mechanically connected molecules, held together like links of a chain rather than through conventional chemical bonds.

(Nanowerk News) Molecular clusters are aggregates of molecules that are held together non-covalently, by relatively weak forces. When these clusters are excited, normally one would expect the cluster ...

An illustration of intracluster bond formation: a cluster containing two biomolecules is exposed to UV light (left), which drives a chemical bond to form between the two molecules (center ...
