X-rays techniques training

X-TechLab will train one hundred (100) technicians, engineers and researchers each year in two experimental characterization techniques: diffraction and X microtomography.

Crystallography and X- ray techniques
Areas for structural studies applied to different issues of interest in life sciences, agriculture, environment and energy.
Tomography and mathematical engineering
Development and implementation of a methodology for the development of innovative, ecological materials adapted to the local environment. This methodology implements a chain comprising the acquisition of 2D images allowing the 3D reconstruction of the interior of the samples, the extraction of morphological data using mathematical methods and numerical calculations.
Conditions of eligibility for the program
An international call for applications will be launched before each training session. Applications will be made online directly on our platform.
The selection criteria are as follows:
- Quality of the file
- Degree of motivation
- Relevance of the research project

Mathematical engineering at the service of sustainable development

Microtomography covers a very broad spectrum of applications in the field of materials science. As part of the X-TechLab training, we will focus in particular on the unique potential of this technique for the development of a sustainable, ecological and comfortable habitat. The current model in Africa relies almost exclusively on the systematic use of concrete, being far from offering optimal performance.

The design and optimization of a new generation of materials from local ingredients for a comfortable and environmentally friendly habitat requires the mastery and implementation of specific theoretical and experimental tools. In addition to conventional thermomechanical tests, our approach is to couple data from nondestructive investigative means (X-ray imaging, spectroscopy) to the use of mathematical algorithms to extract material characteristics.

All of these innovative tools and methodologies will be one of the major achievements in the training for participants wishing to invest in materials engineering applications.
