Talk title: Quantitative EELS: Instrumentation, Techniques and Applications
Alan Craven started his research career as a PhD student of Archie Howie in the Cavendish Laboratory, where he built a UHV field emission scanning electron microscope for surface studies. He then became the PDRA in charge of the first VG HB5 in the Cavendish before taking up a Lectureship at Glasgow University. He subsequently became Senior Lecturer, Reader and Professor. Latterly led the Solid State Physics Research Group before retiring in 2012. He is now Professor Emeritus and Senior Honorary Research Fellow there. During his career, he was Secretary and Chair of the EMAG Committee, Secretary of BJCEM, a member of RMS Council, a member of the Executive Council of IFSM and a member of the SuperSTEM Management Committee. He was recently made an Honorary Fellow of the Royal Microscopical Society.
Throughout his career, his research focused on developing instrumentation and techniques for STEM-EELS and applying them to a wide range of materials systems. In recent years, he has worked on measuring experimental EELS cross-sections and using them to analyse precipitates within the steel matrix. Part of this programme involved improvements to the coupling of the EELS signal into the spectrometer and the correction of spectral data for artifacts introduced by the spectrometer itself.
Talk title: In situ liquid TEM to study the lithiation dynamics in battery materials
After obtaining his PhD thesis on nanomaterials and electron microscopy at the Sorbonne University in Paris, he worked for 5 years on energy materials and in situ experiments at the Argonne National Laboratory in Chicago. Since 2015, he is a CNRS researcher in the LRCS laboratory in Amiens (France). He studies the dynamics of lithiation in Li-ion battery materials in multi-scale and multimodal modes based on the development of in situ/operando methods via TEM and X-ray tomography techniques. His research is today strongly involved in the use and development of machine/deep learning tools for image processing and data analysis. He is also responsible for the electron microscopy/X-ray platform of the RS2E French battery network.
