Scanning tunnelling microscopy shows chrial molecules to self-assemble on metal surfaces Two forms of a prism-shaped molecule can arrange themseleves into separate groups on a gold surface ...

A research project led by chemists at the University of Warwick first used ultrahigh resolution scanning tunnelling microscopy to see the exact location of atoms and bonds within a molecule, and ...

Using an ultra-thin and sharp needle tipped with a single carbon monoxide molecule frozen to minus 266 degrees centigrade, researchers from the University of Warwick and Cardiff identified and ...

Molecular Chains Line Up To Form Protopolymer Date: December 16, 2004 Source: Penn State / Eberly College Of Science Summary: A new chemical state, designated a "protopolymer," has been observed ...

They also have molecular snippers - enzyme catalysts - that cut the grass on to which they're clasped. So, while the other legs remain fixed, the newly free one waves around until it finds a new ...

The team first used their STM to locate a methylaminocarbyne (CNHCH 3) molecule that was fixed to a platinum surface. Then they turned up the voltage, increasing the flow of electrons.

For example, if we can better understand DNA at an atomic and molecular level, that will help us fine-tune and tailor health care according to patients’ needs. The possibilities are endless. A big ...
