1、.Atomic Structure NotesAdapted from the Science Help on Line (E. Muniz/G. Maynes)I. Development of the Atomic Theory Democritus may not have been the first of the ancient Greeks to suggest an atomic theory, this distinction goes to his teacher Leucippus, but his name is often associated...

Atomic Structure Notes Atomic Structure Notes • An atom is not the smallest particle of matter • Atoms are the smallest type of unique matter • All atoms are made up of subatomic particles which are identical in all atoms Atomic Structure Notes • It is the way in which these subat...
Here we determine the 3D atomic positions of M/HEA nanoparticles using atomic electron tomography36 and quantitatively characterize the local lattice distortion, strain tensor, twin boundaries, dislocation cores and chemical short-range order (CSRO). We find that the high-entropy alloys have larger ...
Here we determined the structure of the asymmetric unit of the inner ring (IR monomer) at 3.73 Å resolution by single-particle cryo-electron microscopy, and created an atomic model of the intact IR consisting of 192 molecules of 8 nucleoporins. In each IR monomer, the Z-shaped Nup...

Short-range order: the Loewenstein’s rule in aluminosilicates The disorder in many materials is neither random nor correlated. This intermediate case is characterized by large amounts of possible stable configurations, as in randomly-disordered crystalline systems. From another side, however, the diff...
The Periodic Table of the Elements, developed independently by Mendeleev and Meyer in the late 19th century, represents a remarkable achievement in our understanding of the structure of the atoms and the chemical and physical properties of the elements. Traditionally, the Periodic Table includes the ...
Using a multi-component glass-forming alloy as proof of principle, we quantitatively characterize the short- and medium-range order of the 3D atomic arrangement. We observe that, although the 3D atomic packing of the short-range order is geometrically disordered, some short-range-order structures ...
Although structured water adlayers and 2D ice have been imaged, capturing the metastable or intermediate edge structures involved in the 2D ice growth, which could reveal the underlying growth mechanisms, is extremely challenging, owing to the fragility and short lifetime of those edge structures. ...
