The 3rd International Online Conference on Crystals

Online | 15–30 January 2022

Volume Editor:
Helmut Cölfen, Universität Konstanz, Germany

Cover Story: This volume gathers the papers that were presented at the 3rd International Online Conference on Crystals held from 15 to 30 January 2022 in Sciforum. This is a new and improved initiative based on the experience from the previous two editions, which affords the opportunity for researchers engaged in the study of crystalline materials to present their research and exchange ideas with their colleagues. The conference was organized around the following topics and related themes: Liquid Crystals, Organic Crystalline Materials, Inorganic Crystalline Materials, Crystal Engineering, Biomolecular Crystals, Macromolecular Crystals, Hybrid and Composite Crystalline Materials, Minerals and Biominerals, Industrial Crystallization, Phase Transformations in Crystalline Materials, and Software/Tools to Deal with Crystal and Crystallographic Issues.
