Abstract

The first results from our group that have been obtained using the newly installed aberration-corrected STEM microscope (JEOL JEMARM200F) are reported. Studies were carried out on noble metal nanoparticles and their corresponding alloys and/or core-shell structures. In this paper we focus on some of the exciting areas of research that have been under investigation in our group. These include studies on Au nanoparticles and core-shell Au-Pd nanoparticles. In addition, studies that were carried out on very small clusters namely Pd-Ir and other similar systems have also been high-lighted in this report.
