The applicability of the structural unit model, developed for tilt boundaries by Sutton and Vitek (1983), to (001) twist boundaries in f.c.c. metals is investigated. The model is found to be useful in discussing the continuity of boundary structure with misorientation and the Burgers vectors ...
The atomic structures of all the boundaries studied were found to be very similar for both the descriptions of atomic interactions. This suggests that the principal features of the structure of (111) twist boundaries found in this study are common to all f.c.c. metals. At the same time it...
Alkali metals are widely studied in various fields such as medicine and battery. However, limited by the chemical reactivity and electron/ion beam sensitivity, the intrinsic atomic structure of alkali metals and its fundamental properties are difficult to be revealed. Here, a simple and versatile me...
Here, we have employed single-walled carbon nanotubes as test tubes, and an ‘atomic injector’ coupled with aberration-corrected transmission electron microscopy, to enable in situ imaging of the initial steps of nucleation at the atomic scale. With three different metals we observed three main ...
Exposure to high levels of metals such as lead, zinc and copper can have a severe impact on human health. This is an issue that humanity has experienced since the production of metal objects began. Both mining and processing of metal can also enrich soil and water in noxious substances, ...
Atomic structure of the nanowire for various transition-metal dichalcogenides: (a) atomic structural model of the nanowire, where dashed red triangles indicate the orientation of each layer in the nanowire, and (b) experimental (left) and simulated (right) STEM Z-contrast images of individual MoSe...
However, direct experimental observation of the 3D local chemical order has been difficult because energy dispersive spectroscopy integrates the composition of atomic columns along the zone axes7,32,34 and diffuse electron reflections may originate from planar defects instead of local chemical order35. ...
From the XRD data, we also derive the pair distribution function of both alloys, which allows us to correlate the atomic structure with the Invar effect in these BMGs. We further show that the Invar effect is not just a macroscopic effect but has a clear atomistic equivalent in the average...
Crystal Structures and Properties of Metals (Coursera) In this course, we will present atomic bonding and its relation to crystal structure and physical properties. A particular focus will be on the different types of cubic structures. There will be an introduction to planes and Miller Indices....
