Session 1 Corrosion: 11:15 a.m.–12 p.m.

Corrosion is a $2.6 trillion dollar problem that accounts for 3.4% of the global GDP, therefore it is well understood that testing and developing better materials to increase the durability of infrastructure such as bridges and ships could save $375-$875 billion annually. To develop resistant materials and corrosion-effective mitigation strategies, a deeper understanding of materials used, and the corrosion processes must first be elucidated.

Using the in-situ TEM systems from Protochips such as the Atmosphere AX (gas cell) and Poseidon AX (liquid cell), researchers can directly observe corrosion processes such as initiation and progression at the nanoscale in real time and under relevant conditions. By introducing corrosive environments while simultaneously monitoring material responses, valuable insights into the kinetics of corrosion reactions can be observed at the nanoscale.

Session 2 Catalysis: 12:15–1 p.m.

To combat climate change and the release of harmful chemicals in the environment, highly efficient catalysts must be developed. Using Atmosphere AX, the in-situ gas cell system from Protochips, researchers can investigate the morphology and atomic structure of catalyst materials, including nanoparticles, nanowires, and other nanostructures to develop more stable and sustainable catalytic systems. Moreover, in-situ TEM allows researchers to perform nanostructure characterization of catalyst-substrate interactions at high spatial resolutions to better understand catalytic processes including formation and evolution of reaction intermediates, surface restructuring, and catalyst deactivation in real time and under relevant catalytic conditions.
