Observation of bending, cracking and jumping phenomena on cooling and heating of tetrahydrate berberine chloride crystals
CrystEngComm, 2018•pubs.rsc.org
The crystals of tetrahydrate berberine chloride exhibit a variety of instantaneous mechanical
responses (cracking, bending and jumping) on cooling as well as on heating at room
temperature. In either direction, the thermo-mechanical responses are manifested by rapid
dehydration to a new dihydrated phase with the complete loss of crystal integrity due to the
sudden release of an energetically unfavorable arrangement of water molecules.
