Astatine is the last member of the halogen family, which also includes fluorine and chlorine. These chemical elements have a distinct feature: they are able to form an unusual kind of bond with molecules. Yet for astatine, the existence of this specific halogen bond had never before been proven. This …+
Medicine for Materials
Did you know that materials have health problems too? To diagnose their structural integrity, researchers are increasingly using techniques similar to those used in the medical field for humans. X-rays, temperature checks and ultrasound imaging are just a few of the tools that help detection of abnormalities in parts. The …+
What is an eco-material?
Reducing the environmental footprint of human constructions is one of the major issues facing the ecological transition. Achieving this goal requires the use of eco-materials. Gwenn Le Saout, a researcher in materials at IMT Mines Alès, explains what these materials are, their advantages and the remaining constraints that prevent their large-scale …+
Taking 3D printing to the next level
At the beginning of 2018, IMT Lille Douai unveiled an additive manufacturing platform dedicated to manufacturing large-scale parts: LASCALA. This equipment is a worldwide innovation. Its capacity to use any type of polymer even enables it to print 3D composite parts measuring several meters. The scientific challenge has been successfully met and …+
What is photomechanics?
How can we measure the deformation of a stratospheric balloon composed only of an envelope a few micrometers thick? It is impossible to attach a sensor to it because this would distort the envelope’s behavior… Photomechanics, which refers to measurement methods using images and computer analysis, makes it possible to …+
What are the latest innovations in additive manufacturing?
Although additive manufacturing is already fully integrated into industrial processes, it is continuing to develop thanks to new advances in technology. The Additive Manufacturing Tech’Day, co-organized by IMT Mines Alès and Materiautech – Allizé-Plasturgie, brought together manufacturers and industry stakeholders for a look at new developments in equipment and material. …+
Composite Materials: the race to keep going faster
In the world of materials, composites are currently undergoing a transformation that is just a significant as the plastics boom in the 1960s. To massively integrate these materials into high-volume production markets—automotive, aeronautics, rail, etc.—manufacturers must further reduce the time it takes to mold the parts. This complex goal is …+
Julien Bras: nature is his playground
Cellulose is one of the most abundant molecules in nature. At the nanoscale, its properties allow it to be used for promising applications in several fields. Julien Bras, a chemist at Grenoble INP, is working to further develop the use of this biomaterial. On November 21st he received the IMT-Académie des …+
A new laser machining technique for industry
FEMTO-Engineering, part of Carnot Télécom & Société numérique institute, offers manufacturers a new cutting and drilling technique for transparent materials. By using a femtosecond laser, experts can reach unrivalled levels of precision when manufacturing ultra-hard materials. Jean-Pierre Goedgebuer, director of FC’Innov (FEMTO-Engineering), explains how the technique works. What is high …+
GreenTropism, the start-up making matter interact with light
The start-up GreenTropism, specialists in spectroscopy, won an interest-free loan from the Fondation Mines-Télécom last June. It hopes to use this to reinforce its R&D and develop its sales team. Its technology is based on automatic learning and is intended for both industrial and academic use, offering application perspectives ranging …+
