Raising the profile of crystallography in the modern world

IUCr Crystal growing competition - Edition 2019


How to participate?

The aim of the competition is to convey your experience of growing crystals through a video.

Each contribution should clearly show or mention the experimental work carried out by the participants during the growing of their single crystals (compounds and methods used are free of choice). Furthermore the contribution should reflect in a creative way on the experimental work and theoretical background and/or applications. It is strongly recommended to use English subtitles when applicable, and to provide the name and age of the participants, along with their photos, as well as the name of the school at the end of the video.

Important dates
