Hollow zeolites for increased catalytic efficiency

Zeolites are crystalline aluminosilicates that can be used for the manufacture of catalysts thanks to their physical and chemical properties and, in particular, their organized and regular microporous network, within which some of the catalytic reactions take place.

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.

Where aviation fuels are concerned... compromise is the name of the game

In the aviation sector, fuels derived from hydrotreated vegetable oils (HEFAa) are seen as an alternative to petroleum based Jet A-1b to reduce the environmental footprint of air transport. However
