BRAGG, in the twenty-fifth annual May Lecture before the Institute of Metals on May 8, dealt with the inner structure, or atomic arrangement, of metals and alloys. In general, when one metal is alloyed into another a series of phases appears....
When the dimension of matter is reduced from the three dimensions to low dimensions or even single-atom scale, distinctive features can be observed, indicating broad application prospects in variety fields, such as energy storage and conversion, topological nanocomponents, and semiconductors. Developing...
The bubble raft model of metal structure created by William Lawrence Bragg played an important role in the study on metals with the advent of electron microscopic visualization of dislocations. This paper focuses on work by Bragg and his co-workers on metals using this model. The film of the ...

In order to quantify the effect of temperature changes on the atomic arrangement, the diffraction peaks were fitted with a Lorentzian function L\left(x\right)=\frac{A}{2\pi }\frac{\varGamma }{{\left(x-{x}_{0}\right)}^{2}+{\left({1}/{ 2}\varGamma \right)}^{2}}, ...
High-entropy alloys (HEAs) with an atomic arrangement of a hexagonal close-packed (hcp) structure were found in YGdTbDyLu and GdTbDyTmLu alloys as a nearly single hcp phase. The equi-atomic alloy design for HEAs assisted by binary phase diagrams started with selecting constituent elements with...
68, where Jones states that the arrangement of the chemical periodic table is based on the atomic weights of the elements, rather than on their atomic number (that is, the number of protons in the nucleus). REVOLUTIONARY SCIENCE: Transformation and Turmoil in the Age of the Guillotine Isotopes...
Chemical vapor deposition (CVD) of TMD-based 2D-2D MSJ heterostructures lacks the control of spatial locations12,14,15, and their active layer is inevitably degraded by thermal budget effect because the synthesis of 2D semiconductors along the edge of 2D vdW metals are still at the embryonic st...
The strong dependence of the hysteresis on the atomic arrangement of the Dependence of MC on magnetic history. The fifth indication for a local magnetic order is the observation of history- and time- dependent in-plane MC (x-direction). We observe a symmetric, parabolic MC (green and black ...
The microscopic stresses defined at each atom, or the atomic level stresses, are effective parameters to describe the local variations in the atomic arrangement in liquids and glasses. We have calculated them for model binary alloy systems both in the amorphous and in the crystalline (fcc and bcc...
