Researchers produce a new model to track atomic movements in nanoparticles

The result got is another strategy that enables recognizing and following the individual atoms in the nanoparticle, in any event, when they are in vibration and under movement.

Up until now, particles present in the nanoparticles were anticipated to be static during observations. Nonetheless, the investigation of 3D atomic-scale images by the analysts showed that the original prediction isn’t sufficient. Maybe, they uncovered the dynamic behavior of the atoms by employing a new analytical technique.

The scientists selected a famous catalytic nanoparticle material called molybdenum disulfide. The material’s atomic structure is generally known and accordingly proved to be a decent platform for clarifying the 3D atomic-resolved pictures gathered at the Lawrence Berkeley National Laboratory. The special TEAM 0.5 electron microscope used for this reason gives the highest picometer-scale resolution in the world.

The new method has been clarified and revealed in the journal Nature Communications.

New Model Ensures Identification of Atoms

The mathematical model enables distinguishing the individual atoms in the nanoparticle, in any event, when they are moving. The model calculates both the intensity and width of the atoms in the pictures.

Moreover, the new model empowers correcting changes to the nanoparticles as a form of oscillations acquired from the illumination of energetic electrons in the electron microscope. This will enable scientists to focus on the chemical data hidden in the picture one atom at a time. This is the main concept of the research.

Next Step in Measuring Function

The researchers expect that the new successful model will be employed by different scientists within their area of research. The model will likewise offer a platform for the work of Stig Helveg’s new basic research center at the Technical University of Denmark (DTU), VISION.

The target will be to move one step beyond by incorporating the atomic-resolved pictures with measurements of the catalytic characteristics of the nanoparticles. The bits of knowledge acquired from the study will support the advancement of nanoparticles for catalytic processes as part of the shift to sustainable energy.

The international research group behind the new imaging model included Fu-Rong Chen from City University Hong Kong, Dirk van Dyck from the University of Antwerp, Christian Kisielowski, and Bastian Barton from Lawrence Berkeley National Laboratory, Lars P. Hansen from Haldor Topsoe A/S, and Stig Helveg from DTU.
