Team measures the breakup of a single chemical bond

The team used a high-resolution atomic force microscope (AFM) operating in a controlled environment at Princeton's Imaging and Analysis Center. The AFM probe, whose tip ends in a single copper atom, was moved gradually closer ...

Programmable synthetic materials

Artificial molecules could one day form the information unit of a new type of computer or be the basis for programmable substances. The information would be encoded in the spatial arrangement of the individual atoms—similar ...

Tricky feat with stand-up molecule

In recent decades, researchers have been able to produce structures from single atoms. One of the first examples was presented by D. M. Eigler and E. K. Schweizer in 1990 in Nature, a tiny IBM logo formed from just a few ...

A simple method etches patterns at the atomic scale

A precise, chemical-free method for etching nanoscale features on silicon wafers has been developed by a team from Penn State and Southwest Jiaotong University and Tsinghua University in China.

'Tiny clocks' crystallize understanding of meteorite crashes

Almost two billion years ago, a 10-kilometre-wide chunk of space slammed down into rock near what is now the city of Sudbury. Now, scientists from Western University and the University of Portsmouth are marrying details of ...
