Obtaining 3D Chemical Maps by Energy Filtered Transmission Electron Microscopy Tomography Lucian Roiban1, Loïc Sorbier2, Charles Hirlimann3, Ovidiu Ersen3 1Univ Lyon, INSA-Lyon, Université Claude Bernard Lyon 1, 2IFP Energies nouvelles, 3Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS) This paper describes a protocol to achieve 3D chemical maps combining energy filtered imaging and electron tomography. The chemical distribution of two catalyst supports formed by elements that are difficult to distinguish by other imaging techniques was studied. Each application consists of mapping overlapped chemical elements - respectively spaced-ionization edges.
Original Experimental Approach for Assessing Transport Fuel Stability Kenza Bacha1, Arij Ben Amara2, Maira Alves Fortunato2, Perrine Wund2, Benjamin Veyrat2, Pascal Hayrault2, Axel Vannier3, Michel Nardin1, Laurie Starck2 1Institut de Science des Matériaux de Mulhouse, 2IFP Energies Nouvelles, Institut Carnot IFPEN Transports Energie, 3Technocentre Renault Oxidation stability of transport fuels has become a concern for future fuel development. This work presents an original methodology developed by IFP Energies Nouvelles for assessing fuel stability using two different reactors. This methodology was successfully applied to gain an in-depth understanding of the oxidation kinetics and pathways of model molecules and commercial fuels.
