Counting Statistics and Accuracy within Electron Microscopy

Catalysis plays a key role in society today. Vast amounts of chemicals are produced from catalyzed reactions and energy production depends heavily on catalysis. Catalysis often consist of nanosized particles on a substrate making them ideal for characterization by electron microscopy. Over time, the catalytically active nanoparticles tend to grow in size resulting in a loss of surface area. This phenomenon is known as sintering.

This project aims at investigating factors governing nanoparticle sintering. We will determine the validity of existing routines and try to develop novel and more bullet proof counting routines using electron microscopy. The developed routines could be extended to other nanostructures.
