Introduction

Nanoparticles are important scientific tools as they act as a link between bulk materials and atomic or molecular structures. They have exceptional optical properties and the potential to produce quantum effects.

Ruthenium is one of the most effective hardeners for palladium and platinum, and hence it is alloyed with these metals to make electrical contacts for laboratory equipment and severe wear resistant electronics. Ruthenium nanoparticles also serve as versatile catalysts.
