Adj. 1. atomic - of or relating to or comprising atoms; "atomic structure"; "atomic hydrogen" 2. atomic - (weapons) deriving destructive energy from the release of atomic energy; "nuclear war"; "nuclear weapons"; "atomic bombs" nuclear 3. atomic - immeasurably small little, small - li...
Of especial importance is the local structure in a molecule involving a few atoms coordinated to a specified centre, for this results in the characteristic notion of a functional group; the presence of such groups in a molecule expresses the specific properties of the corresponding substance (acid...
Medium- and high-entropy alloys (M/HEAs) mix several principal elements with near-equiatomic composition and represent a model-shift strategy for designing previously unknown materials in metallurgy1–8, catalysis9–14 and other fields15–18. One of the
Figure 3. Atomic structure of the hexagonal S-layer lattice (A) Each csg monomer is arranged into hexamers in a two-dimensional lattice. D1–D6 for one csg monomer are shown in a surface representation. (B) Magnified view of the hexameric interface (dashed black box in A) reveals glycans...
By contrast, the precise control of the mesoporous structure in the matrix material, which directly correlates with mass diffusions and may play a dominant role in delivering industrially relevant reaction rates, has been overlooked. Here we report a general method for the synthesis of a single ...

In all likelihood, these space pilgrims will join up in "wagon trains" for the trip out. Each band of hardy trail blazers will form their own society, agreeing among themselves on its structure and systems of self-governance. Each family buys a launch pod and a cargo pod, both tanked up...
