McMaster researchers have taken atomic-level images of individual nanoparticles during heating that could lead to improved fuel-cell technologies at lower cost, reduce dependence on imported oil and minimize greenhouse gas emissions. Credit: McMaster University

Heating nanoparticles and atomic-level tracking allows for the development of other cheaper catalysts, such as platinum-ron nanoparticles. Typically, pricey platinum nanoparticles are used. This technology will reduce dependence on imported oil and minimize greenhouse gases.

Using advanced electron microscopic techniques the team was able to track the atomic-rearrangement process of an individual Platinum-Iron nanoparticle – as it got annealed inside the microscope...
