Yang Cao
School of Mechanics and Materials, Hohai University, China.
Prof. Yang Cao received his PhD degree from the University of Sydney in 2013. He is currently the Laboratory Manager of the Materials Characterization Center at Hohai University in Changzhou, China. Yang has long been dedicated to the study of microscopic deformation mechanisms and the regulation of mechanical properties in structural materials, as well as the development and application of in-situ transmission electron microscopy (TEM) techniques, EBSD/TKD data analysis techniques, and digital image correlation (DIC) techniques. He has published over 80 SCI-indexed papers, including more than 40 as the first or corresponding author, with over 6,500 citations and an h-index of 43. He has been granted 16 invention patents and is ranked among the world's top 2% of scientists. He serves as an Editorial Board Member of the international peer-reviewed journal Microstructures, and as a Young Editorial Board Member of Materials Research Letters and the Journal of Chinese Electron Microscopy Society.
Yang co-authored a highly cited review article entitled "Structural evolutions of metallic materials processed by severe plastic deformation" in Materials Science and Engineering: R: Reports, a journal with a 2023 Journal Impact Factor of 31.6. Yang was the first to propose a method for visualizing shear strain induced by high-pressure torsion in a dual-phase material. By employing this method to visualize shear strain, he observed phenomena such as stress concentration caused by inhomogeneous strain distribution and the gradual approach to an idealized state as shear strain increased. This work earned him the UFG VI Young Scientist Award at the 2010 TMS (The Minerals, Metals & Materials Society) Annual Meeting & Exhibition in Seattle, Washington, USA.
Yang was among the early researchers involved in the application of transmission Kikuchi diffraction (TKD) technology. In 2014, he co-authored a study demonstrating the application of TKD in a scanning electron microscope for characterizing deformed ultrafine-grained and nanocrystalline materials. Compared with conventional EBSD, TKD offers significantly improved spatial resolution, which can reach approximately 2 nm. Today, this technology is widely used in materials characterization.

Abstract
In this talk, I will review the results obtained by the Nanomidas group at INMA in the topic of nanofabrication using focused electron and ion beams, as well as its application to various topics in Physics and Materials Science. Focused electron beams are produced in a Scanning Electron Microscope (SEM) and are mainly used for imaging or for electron beam lithography, whereas the Focused Ion beam (FIB) is mostly popular for nanopatterning via the local removal of material. Interestingly, if one combines focused electron or ion beams with a precursor material, a local deposit can be grown, and the techniques are respectively named Focused Electron Beam Induced Deposition (FEBID) and Focused Ion Beam Induced Deposition (FIBID). The talk will describe the fundamentals of these techniques and a few examples of application in the fields of Magnetism, Superconductivity, Quantum Technologies and Nanoelectronics.
