Yet all these diverse materials share one thing in common—they manifest piezoelectricity while in the solid phase.
WebbPresentation on protein crystallization theory by Dr. Diana Monteiro (HWI) from the 2024 BioXFEL Crystallization Workshop. Protein crystallization is the process of formation of a regular array of individual protein molecules stabilized by crystal contacts. If the crystal is sufficiently ordered, it will diffract. Some proteins naturally form crystalline arrays, like aquaporin in the lens of the eye. In the process of protein crystallization, proteins are dissolved in an aqueous e…
