The review investigates the self-assembly of block molecules, leading to the formation of diverse 2D periodic nanopatterns, ...

Nature Nanotechnology - Nano-architectures by covalent assembly of molecular building blocks. ... The inset shows the corresponding chemical structure. d, STM image (41 × 41 nm 2) ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...
