Union</h2> <p>Formally admitted to the International Council of Scientific Unions (ICSU) on 7 April 1947, the IUCr remains committed to its goals of promoting international cooperation in crystallography and advancing the science, promoting international publication of crystallographic research, facilitating standardization of methods, units, nomenclatures and symbols, and forming a focus for the relations of crystallography to other sciences. As more and more new approaches to exploring the structure of matter at the atomic scale develop, the IUCr embraces a growing range of novel and exciting scientific fields.</p> <footer> <a class="btn"
