α-helices and β-strands are predominant in peptide materials based on secondary structural elements arrangement from hydrogen bond pattern. A peptide material is thus assembled from one or more types of building blocks (of the same secondary structure). Based on its predominant propagation mode (...

Argon Ar 19 Potassium K 20 Calcium Ca Conclusion Because an element’s chemical characteristics are determined by the number and arrangement of electrons in its atoms, these issues disappear when atomic number rather than atomic mass is employed to generate a periodic table. The nuclear charge, in...
The films are sputtered in ultra-high purity argon gas at a pressure of 5.8 × 10−3 Torr. Sputtering guns are arranged in a tetrahedral geometry with the substrate. This arrangement leads to a compositionally graded film, where the film at each point in the library represents an alloy ...
The rigid form of the CC bond gives rise to geometric isomerism. The different arrangement of the same nuclei around the CC bond can cause large differences in the overall shape of molecules. Isomerism also arises from the different spatial arrangement of chemical groups around an asymmetric C ...

While the mathematical symmetry is nice and neat for placement of time at the 0th dimension, the arrangement of time to this position seems necessary as derived from the atomic structure of the periodic table. Matter, itself, is the 4th dimension because the mathematics of the 4d structure sta...
Fig. 1: Atomic structure of unit cells in iron garnet films. a The atomic model of garnet in the unit cell. b The projected atomic arrangement along the [001] zone axis. c In-depth view of the unit cell along the [001] axis. Atomic columns labeled as a and c are occupied by dode...
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 ...
