resulting in a five-O-coordinated Co single-atom site, which is denoted as a single Co (II)-O5site. Interestingly, the brightness of individual dots on IL/Co-bCN in the HADDF-STEM image (Supplementary Fig.7b) maintains, implying the introduction of IL does not influence...
A linear relationship is found between the best equilibrium bond lengths and their MP2 or B3LYP estimates. These (and similar) linear relationships permit to estimate the CO bond length with an accuracy of 0.002Å within the full range of 1.10–1.43Å, corresponding to single, double, and ...
In this paper, bond parameters, namely surface roughness, stacking sequence, and manufacturing pressure, affecting failure of the co-cured single and double lap joints with steel and carbon fiber-epoxy composite adherends were investigated through static and dynamic tensile tests. Systematic failure ...
Although the term ‘coevolution’ occasionally refers to the joint evolution of different features of a single species (e.g., enzymes in a pathway and sex-specific features used in sexual interactions), it usually (and in this article) refers to the joint evolution of two or more species or...

There is considerable controversy around the exact timing of the emergence of the human species, as well as its place (one single place or multiregional) and its abruptness or graduality, particularly in light of the extensive admixture with other hominins (see Meneganzin & Bernardi, 2023; ...
[89], the topological structures are quite different from the common hexagonal carbon model, which can locally induce Gaussian curvatures and alter the bond length and angle, with rehybridized electron orbitals. These properties can also endow topological aberrant sites with local charge/spin ...
are slightly longer than that in salicylaldiminato Ni(II) complex (1.910 Å)10, suggesting similar Ni-O bond strengths/robustness even for the shared O in2. Fig. 1: Structure formula and single crystal structures of catalysts.
Mediated by the central Cr atom, the O-O bond length of the peroxide-type intermediate elongates continuously and passes over the second transition state (TS2) with a substantially low energy barrier of only 0.09 eV to come to the final state (FS), releasing a large energy of 4.52...
