Seeing light elements in a grain boundary: A further step in unravelling materials’ properties down to the atomic scale
Scientists of the Max-Planck-Institut für Eisenforschung develop a workflow and code to characterize defects in steels
09-Aug-2023 - To develop advanced materials, a deep understanding of their underlying microstructure and chemistry is necessary. Knowing how defects influence the interplay between microstructure and chemical composition is crucial, as they are the entry gate for material’s failure due to corrosion or crack ...
Atomistic Insights into Electrocatalysis
28-Mar-2018 - Electrocatalysts are important for many industrial processes as they enhance the conversion of electrical energy into chemical energy and thus help to store excessive electrical energy generated by renewable energy resources. Hydrogen is expected to be crucial for the storage of chemical energy. ...
Edges and corners increase efficiency of catalytic converters
X-rays reveal oxide islands on noble metal nanoparticles
28-Mar-2018 - Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges. This is one of the findings of a study carried out at DESY’s X-ray source PETRA III. A team of scientists from the DESY NanoLab watched live as noxious carbon monoxide (CO) was ...
Unexpected degree of order found in interior grain boundaries of polycrystalline materials
11-Oct-2017 - Scientists in the United States and China have announced a discovery that they believe could enable the engineering of alloyed materials that are stronger and more ductile and possess superior electrical, magnetic and physical properties. The researchers said they had found a surprising degree of ...
New technique provides detailed views of metals’ crystal structure
Method uses readily available tools to quickly determine materials’ properties.
12-Jul-2016 - Researchers at MIT and elsewhere have developed a new combination of methods that can provide detailed information about the microstructure of polycrystalline metals. Such materials — composed of a random matrix of multiple small crystals rather than one single large crystal — are widely used for ...
