GENERAL X-RAY SERVICE OF THE UPV/EHU: MOLECULES AND MATERIAL UNIT

Introduction

The General X-ray Service  of the University of the Basque Country/EHU attempts to provide support for basic and applied research in, among others, the different areas of knowledge of Geological Science, Chemistry, Materials Science, Aeronautics, Pharmacy, Biochemistry, Archaeology, Palaeontology, Anthropology and Environmental Science, in addition to helping to provide a service in the fields of Construction, Mining Prospecting and Civil Engineering. Researchers may also access the service from the Basque Network of Science and Technology, and it is available to other researchers outside the UPV/EHU, and other public and private institutions - both national and international.

Integrated in the General Service of X-ray Analysis, the Unit Molecules and Materials, provides the structural study of organic and inorganic materials in the form of single crystals or polycrystalline sample, under a wide range of conditions.

The performance of this unit covers all aspects of the study of crystal structure from diffraction data: the selection and installation of the sample, previous studies of symmetry, diffraction data collection, the resolution or structural identification and the analysis of results.

The available equipment also enables structural studies starting from diffraction data of polycrystalline materials. This technique allows us to identify the crystalline phases present in the sample without destroying it, allowing you to recover the material without deterioration. It is possible to characterize, in a wide variety of materials, his crystalline structure, or the presence of texturin or residual stresses, material fatigue, etc., These studies were performed by analyzing the profile of diffractogram using, in the cases that require it, the Rietveld method. The X-Ray Service: Molecules and Materials Unit supports basic and applied research through scientific and technical advice and the use of a high-performance infrastructure in materials analysis by X-ray diffraction, with applications in many areas knowledge.
