Proclamation of 2014 as International Year of Crystallography

The birth of modern crystallography took place almost 100 years ago, when Max von Laue carried out the experiment that showed that X-rays were diffracted by crystals, and the Braggs (father and son) shortly after in 1913 showed that the diffraction of X-rays can be used to determine accurately the positions of atoms within a crystal and unravel its three-dimensional structure. The significance of these experiments was realized immediately. Max von Laue received the Nobel Prize in 1914, and the Braggs the year after.

Since its birth 100 years ago, modern crystallography has developed in close collaboration with other scientific disciplines. As crystals also diffract neutrons and electrons, the scientific focus of crystallography has enlarged to cover all aspects of structural science involving X-rays, neutrons and electrons, and encompasses studies of both crystalline and non-crystalline materials.

More about the International Union of Crystallography (IUCr) and the objectives for the International Year of Crystallography can be found at the IUCr website.
Welcome to Reciprocal Net

The Reciprocal Net is a distributed database used by research crystallographers to store information about molecular structures; much of the data is available to the general public. The Reciprocal Net project is still under development. Currently, we have 18 participating crystallography laboratories online. The project is funded by the National Science Foundation (NSF) and part of the National Science Digital Library. More about Reciprocal Net.
