The technique is based on the detection of chemical shifts of carbon atoms, which appear as distinct peaks.
This means that where molecular graph symmetry is broken only by charge states in a delocalised system, the InChI will regard as equivalent atoms which appear as different charge states in the SMILES string.
In the observed cryo-EM images the most prominent features of lipid membranes are the electron-dense head groups, rich in phosphorous atoms, which appear as high contrast dark lines when observed on end (along the direction of the electron beam see for example [ Tahara and Fujiyoshi, 1994; Lambert et al., 1997]).
In the case of Cu-containing 6xxx alloys, precipitates were found to be surrounded by an apparently single atomic layer of segregated Cu atoms, which appeared to inhibit the precipitate growth, thus inhibiting the number of pits occurring.
At the cluster surface, ⋅OH groups of PVA molecule, which appear under gamma irradiation, anchor the Ag+ ion and reduce these ions to form of Ag0 atoms.
The 16-carbon fatty acid, palmitic acid, for example, undergoes a total of seven such cycles, yielding eight molecules of acetyl coenzyme A and 14 pairs of hydrogen atoms, seven of which appear in the form of FADH2 and seven in the form of NADH + H+.
The HAADF-HRSTEM image shown in panels a and c are clear evidence for the presence of isolated atoms, small clusters, and nanoparticles, which appear as white dots, which correspond to a high Z element.
Briefly, one can relax this assumption by replicating atoms and involved edges in metabolites which appear in a reaction more than once but this topic is not pursued further here.
Geim had isolated the first two-dimensional material ever discovered: an atom-thick layer of carbon, which appeared, under an atomic microscope, as a flat lattice of hexagons linked in a honeycomb pattern.
These were not substantially modified either by the insertion of a para-fluorine atom useful as a radiolabel, which appeared to comfortably sit at the outer opening of the pocket.
The single-phase feature of the Co25Ni25Fe25Al7.5Cu17.5 HEA principally resulted from remarkably high mutual solubility in most binary atom-pairs of the constituent elements, which appears to correspond to a high entropy of mixing.
