Sulfur power! Watch the video on the thesis by Teddy Roy, PhD researcher at IFPEN

In “C’est pas Soufré” (Sulfur power), Ted and Denis explain the hydrotreatment process used in refineries to reduce fuel-related pollution, along with one of the research strategies developed at IFPEN to improve the catalyst used via the presentation of recent results on the modification of the γ-Al2O3 support surface chemistry by phosphorous

Semantic segmentation through deep learning in materials sciences

Semantic segmentation conducted on microscopy images is a processing operation carried out to quantify a material’s porosity and its heterogeneity. It is aimed at classifying every pixel within the image (on the basis of degree of heterogeneity and porosity). However, for some materials (such as aluminas employed for catalysis), it is very difficult or even impossible using a traditional image processing approach, since porosity differences are characterized by small contrasts and complex textural variations. One way of overcoming this obstacle is to tackle semantic segmentation via deep learning, using a convolutional neural network.
