The intensity of color represents the concentration of elements. The interfacial region is indicated by blue arrows, where signals of the Tm element are found along a zigzag line structure. c The spacing dh defined as shown in (a) is measured and compared across the APBs. The error bar is...
This suggests that there may be different ways of assembling barrier elements but that amyloid-like structures are not fundamental for NPC function. In any case, the key role of FG motifs in cohesive interactions is conserved across species19,20,23,26,33,34. How the NPC barrier combines high...
Assuming that the volume per atom scales with the cube of the Goldschmidt radii of the elements, vZr≈ 1.95vCu, so the drift shows that DCu ≫ DZr, as expected (§1). Modelling of interdiffusion in amorphous Ni-Zr multilayers [9,10] showed that, at least in quasi-steady state, a ...
This situation is rare for atoms of the elements of the second row of the periodic table (presumably due to their small size and the resulting steric crowding) but fairly common for those of the third and lower rows, where the number of valence-shell electrons can be 10, 12, or even ...
and unlocking their full potential in various applications. In this context, the atomic substitution method has emerged as a favorable approach. It involves the replacement of specific atoms within TMC structures with other elements and possesses the capability to regulate the compositions finely, ...
Intuitively, Eu3+ ions that replace Sr2+ ions in the SSO lattice can be readily dissolved because the ionic radii of nine-coordinate E u3+ (~ 1.30 Å) and ten-coordinate Eu3+ (~ 1.35 Å) are very close to those of nine-coordinate Sr2+ (~ 1.31...
Periodic Table of Elements - The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. In the periodic table, the vertical columns are called groups and the horizontal rows are called peri
Proximity histogram of the surface oxide feature marked as 1 in Fig. 1(b). All complex ions are decomposed into their constituent elements. Full size image Most interestingly, the data demonstrates there is a significant increase in the hydrogen content at the interface between the metal and oxi...
, the number of elements in the dataset. The set of all feature vectors and corresponding labels can be grouped in the random variables X and y, respectively, where X = (x1,⋯, xn) and y = (y1,⋯, yn). Here, y consists of values of molecular properties to be learned. yi is...
