The chemical species involved in the reactions are composed of seven elements - H, He, C, O, N, S and Fe - with H and He dominating the elemental abundances. The model considers a chemical environment which is carbon-rich (i.e. C/O > 1)....
1540s, in alchemy, "composed of contrasting elements which, in proper proportion, neutralize each other," also, of states, rulers, etc., "refraining from taking sides in a fight, not engaged on or interfering with either side" (probably from a similar meaning ofneutralisin Medieval Latin),...
Sense effect elements Explanation Buoyancy A sense of buoyancy is felt, such as floating (positive buoyancy), sinking (negative buoyancy), and stopping (neutral buoyancy), in the water depending on control of buoyancy and weight. Design and assessment of a virtual underwater multisensory effects ...
Several discrete neutral assemblies of various nuclearities, in which the coordination geometries for transition metals include octahedral, tetrahedral, and square planar, integrating main-group elements in supramolecular self-assembly applications allows for the formation of markedly different structural motifs...
Mach’s Elementenlehre of neutral elements and functions was complete on the physical side by his “Raumvorstellungen” paper of 1866, and his first extension of that theory to psychophysics and psychology was made in 1872 in the Conservation of Energy, where his early thinking on the unity ...
Possible diastereomeric pathways, resulting from the presence in intermediate 8 of two stereogenic elements, were also considered (Supplementary Fig. 13). The fragmentation side-reaction25 (Fig. 3, left) proceeds by a SN2-type displacement with a typical trigonal bipyramidal transition state TSfrag....
Main group elements; Silicon; Tridentate ligands Abstract A series of neutral hexacoordinate silicon(IV) complexes (4a, 4b, 5a, 5b, 6a, and 6b) with a SiO3N2C, SiSO2N2C, SiO2N3C, SiSON3C, or SiS2ON2C skeleton have been synthesized and structurally characterized by solid-state and solu...

late 15c., "composed of contrasting elements which, in proper proportion, neutralize each other," from Middle French neutral, from Latin neutralis "of neuter gender," from neuter (see neuter (adj.)). Chemistry sense is from 1660s. Sense of "not taking sides in a fight" (1540s) probably...
