About this collection

This themed issue focuses on crystal engineering of composite materials, particularly in the areas of energy conversion and energy storage, providing insights into the growth behaviour of these complex systems. The issue addresses different aspects of crystal design in and for hybrid materials, such as changes in crystal growth behaviour – namely, changes in morphology or phase, on different supports or by additional components in the system.
