WebMar 21, 2024 · The primary catalyst metal is in solid solution with the secondary catalyst metal, creating a non-segregated crystallographic structure. With prior art catalysts, the individual metal oxide components are segregated crystallographic entities that allow migration of these species to and from the catalyst surface during reforming operations. WebMultiply twinned particles (MTPs) are fascinating crystallographic entities with a number of controllable properties originating from their symmetry and cyclic structure. In the focus of our studies are diamond MTPs hosting optically active defects—objects demonstrating high application potential for emerging optoelectronic and quantum devices.
Crystallographers often explicitly state the type of beam used, as in the terms X-ray crystallography, neutron diffraction and electron diffraction. These three types of radiation interact with the specimen in different ways. X-rays interact with the spatial distribution of electrons in the sample.
