Chemical bonds are forces that hold atoms together in molecules through shared electrons. The rules governing bonding and the shapes of molecules are often thought to be absolute. Geometries of double ...

Rye pollen has been demonstrated to able to slow tumour growth in animal models of cancer. To understand more about this, chemists have determined the 3D ...

Researchers have devised a new technique -- using a sheet of carbon just one atom thick -- to visualize the structure of molecules. The technique, which was used to obtain the first direct images of ...

Bullvalene is a restless molecule. Its bonds ebb and flow in a perpetual series of rearrangements, so that each of its 10 carbon atoms endlessly swaps places with the others. The bizarre consequence ...

Electrical circuits are constantly being scaled down and extended with specific functions. A new method now allows electrical contact to be established with simple molecules on a conventional silicon ...

Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them. Alex Wiltschko began ...

Chemists are constantly tasked not just with designing useful new molecules — for novel drugs, energy-storing materials and countless other jobs — but with designing better ways to make those ...
