Making carbon–carbon bonds is hard. Linking racemic mixtures of two alkyls while simultaneously controlling the stereochemistry of both ends of the product is nigh on impossible. Now Gregory Fu, ...

A racemic mixture of tartaric acid forms mirror-image domains with equal propensity when adsorbed on a copper surface. When one enantiomer is present in a slight excess, however, only ordered domains ...

Achiral molecules have now been assembled into a homochiral porous network at a solid–liquid interface. This has implications for practical processes such as separations, but also for understanding ...
