Smaller-molecule and macromolecular crystallography differ during the choice of attainable techniques utilised to make diffraction-high quality crystals. Smaller molecules usually have few levels of conformational flexibility, and may be crystallized by a wide array of techniques, including chemical vapor deposition and recrystallization. 20 from the 32 crystal lessons are piezoelectric, https://www.3dcrystalshop.co.uk/
