Cristalografía de rayos X, una historia de cien años

The Department of Inorganic Chemistry and Communication Service UPCT in collaboration with the Solid State Task Force of the Spanish Royal Society of Chemistry add to the celebration of the International Year of Crystallography with an audiovisual document (in Spanish) reviewing its centenary history.

Made by Antonio Perez with UPCT teachers José Pérez Pérez and José Luis Serrano Martínez.

Celebrating crystallography

An animated celebration

X-ray crystallography is arguably one of the greatest innovations of the twentieth century, but not that many people know what it is or how it came about. Join us on an animated journey through the 100 year history of crystallography – from the pioneering work of William and Lawrence Bragg in 1913 to the surface of Mars!

Narrated by structural biologist Stephen Curry and produced by animation company 12foot6, the film explores the extraordinary history of crystallography. To date 28 Nobel Prizes have been awarded to projects related to the field and X-ray crystallography remains the foremost technique in determining the structures of a huge range of complex molecules.

This film was produced in celebration of the Bragg Centenary and was funded by STFC.

The Mystery of the Giant Crystals

The Cave of the Crystals (Cueva de los Cristales) in the Naica Mine, Chihuahua, Mexico, houses some of the largest natural crystals ever found. They are selenite, a form of the mineral gypsum (CaSO₄.2H₂O). Juan Manuel Garcíia Ruiz and his colleagues investigate the conditions under which these huge crystals have grown over the course of thousands of years. The temperatures in the subterranean caverns are over 50°C, and the caves are filled with water containing a variety of minerals leached from the surrounding rocks.

El Misterio de los Cristales Gigantes

La Cueva de los Cristales en la mina de Naica, Chihuahua, México, alberga algunos de los más grandes cristales naturales que se han encontrado. Son selenito, una forma del yeso mineral (CaSO₄.2H₂O). Juan Manuel García Ruiz y sus colegas investigan las condiciones en que estos enormes cristales han crecido a lo largo de miles de años. Las temperaturas en las cavernas subterráneas son más de 50° C, y las cuevas están llenas de agua que contiene una variedad de minerales lixiviados de las rocas circundantes.

Il Mistero dei Cristalli Giganti

La Grotta dei Cristalli (Cueva de los Cristales) nella miniera di Naica, Chihuahua, Messico, ospita alcuni dei più grandi cristalli naturali mai trovati. Si tratta di cristalli di selenite, una particolare forma di gesso (CaSO₄.2H₂O). Juan Manuel García Ruiz e i suoi colleghi indagano sulle condizioni in cui questi enormi cristalli sono cresciuti nel corso di migliaia di anni. La temperatura nelle caverne sotterranee è oltre 50° C, e le grotte sono riempite con acqua contenente una varietà di minerali lisciviati dalle rocce circostanti.

Le Mystère des Cristaux Géants

La Grotte des Cristaux (Cueva de los Cristales) dans la mine de Naica, Chihuahua, Mexique, abrite quelques-uns des plus grands cristaux naturels jamais trouvés. Ils sont sélénite, une forme de gypse minéral (CaSO₄.2H₂O). Juan Manuel García Ruiz et ses collègues enquêtent sur les conditions dans lesquelles ces énormes cristaux ont grandi au cours de milliers d'années. Les températures dans les cavernes souterraines sont plus de 50° C, et les grottes sont remplis avec de l'eau contenant une variété de minéraux lessivés des roches environnantes.

X-ray crystal structure analysis and Manchester

From W. L. Bragg to the present day

As part of the 150th anniversary celebrations of the University of Manchester, the Department of Physics and Astronomy organised a special lecture, delivered by Professor J. R. Helliwell, reviewing Lawrence Bragg's association with the university and the many consequent contributions to X-ray crystallography. A notable feature of this lecture was the live demonstrations and experiments illustrating some of the scientific principles discussed.

A detailed commentary was published in Helliwell, J. R. (2009). J. Appl. Cryst. 42, 365, doi: 10.1107/S0021889809002775

Crystallographers in Conference 1965

During the 1965 International Conference on Crystallography held in Melbourne, the opportunity was taken to record some of the great figures in the history of this subject. The twin topics forming the discussion basis for the conference were electron diffraction and the nature of defects in crystals. Among the distinguished scientists present, many had made special contributions to the research on those topics - had, in fact, pioneered a place for themselves in the story of crystallography.

Filmed at the International Crystallography Conference, 1965, Melbourne, Australia, by the CSIRO Film Unit in collaboration with the Australian Academy of Science. With support from UNESCO, the International Council of Scientific Unions, the Australian Academy of Science, the International Union of Crystallography, the International Union of Pure and Applied Physics, the International Atomic Energy Agency and the University of Melbourne.
