Phys.org / Organic solvents enable chirality control in inorganic crystals

Chirality—often described as "handedness"—is a fundamental property of nature, underlying the behavior of molecules ranging from DNA to pharmaceuticals. While chemists have long known how to separate left- and right-handed ...
