X-rays techniques training


We are pleased to announce that the 1st training session of the year 2020, in “Crystallography & X-Ray Diffraction Techniques” and “Tomography & Mathematical Engineering”, will be held from 18 – 29 May 2020 at Agence de Développement de Sèmè City – Cotonou, Benin Republic.

The workshop will cover all aspects:

1. of  single crystal structure determination by X-ray crystallography, including the fundamental concepts such as:

  • fundamentals of x-ray crystallography
  • crystal symmetry
  • crystal diffraction: theory and experiment
  • crystal growth techniques

2. of “tomography & mathematical engineering”

  • Genesis of an X-ray Tomography application
  • Image correlation applied to solids mechanics

Participants will have the opportunity to collect data from their own crystals using D8 QUEST BRUKER.

This workshop is most suitable for Master Degree students, PhD students and Postdocs. The teaching langage is English.

The crystallography session will focus on single crystal  structure determination and participants are strongly encouraged to bring their own samples.

Participants from all countries will be considered. However, qualified applicants from African universities will be preferred. Online applications are open until 13 March, 2020. A total of 20 participants will be selected by training area. The selection results will be announced by 18 March, 2020.

Catering : 

For each day of the training period, the organizing committee offers each participant two coffee breaks and lunch. Dinner and other meals are entirely at the expense of the participants.

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.
