Chemists follow molecules down 'nanowells,' track catalytic reactions in nanoconfinement
Chemists have measured the effects of nanoconfinement in catalysis by tracking single molecules as they dive down "nanowells" and react with catalysts at the bottom.

The electronic origins of fluorescence in carbon nanotubes
Technological progress is often driven by materials science. High-tech devices require "smart" materials that combine a range of properties. An impressive current example is carbon nanotubes (CNTs)—single sheets of carbon ...

A powerful duo
An important aspect of pharmacology is understanding how active drug ingredients cross-react with endogenous molecules. But until now, such reactions could only be determined after the event. The precise details of the interacting ...

Confined within tiny carbon nanotubes, extremely cold water molecules line up in a highly ordered chain
Single-walled carbon nanotubes act like tiny straws that are so narrow that water confined within cannot freeze into its normal crystal-like structure. In particular, in very thin nanotubes, water molecules align in a single-file ...

Scientists discover genes are controlled by 'nano footballs'
Research at the University of York has revealed that genes are controlled by 'nano footballs' - structures that look like footballs but 10 million times smaller than the average ball.
