Enantiomer-specific oriented attachment: formation of macroscopic homochiral crystal aggregates from a racemic system.
Let's get together: Racemic samples of d- and l-enantiomorphous NaBrO3 (or NaClO3) crystals aggregate with nearly complete enantioselection. Centimeter-sized enantiopure megacrystals are often produced, and these can be sorted easily.
