Such orbital cooperativity represents a new physical effect beyond the conventional Stark effect. Moreover, we have found that applying electric fields to the molecule would modify its molecular orbital diagram, depending on the directions of the electric fields; the electric field along the carbon-...
b Molecular orbital diagram for C2, predicting a double bond between the C atoms consisting of 2π bonds, without an accompanying σ bond. The additional electron for the anion C2− is shown in green. c Orbital diagram for C2 from a valence-bond viewpoint. Due to the quasi-degenerate ...
(e.g. from the molecular orbital (MO) diagram and DOS analysis in Fig.3a, and Supplementary Figs.22and23) that donation into 4Ʃg* should be considered. Yet (as Fig.3b, and Supplementary Fig.22show) there is proper overlap between the anti-bonding orbitals of the adsorbate (CO2*) ...
Fig. 9. a) Schematic diagram displaying the overall evolution of wheat straw into few-layer graphene, b, c) SEM, d) TEM, and e) SAED pattern of few-layer graphene. Adapted from [200] after the required permission. In another study, 2D porous carbon nanosheets derived from silk were syn...
To activate a C–O bond in CO2*, we understand (e.g. from the molecular orbital (MO) diagram and DOS analysis in Fig. 3a, and Supplementary Figs. 22 and 23) that donation into 4Ʃg* should be considered. Yet (as Fig. 3b, and Supplementary Fig. 22 show) there is proper ...
The electron density was observed to be more likely to gather around pyridinic N and pyrrolic N from the corresponding model diagram (Fig. 7g-h). Meanwhile, Liu et al. prepared N-doped bamboo-shaped carbon nanotubes with a low degree of graphitization through a one-step pyrolysis method for...
What is the molecular structure of BrF5? What is trigonal pyramidal? What is the orbital diagram for the nitrogen in the molecule below following hybridization (any lone pair electrons are in hybrid orbitals)? What is the formula for carbon tetrachloride?
Diagram of the carbon cycle. The black numbers indicate how much carbon is stored in various reservoirs, in billions of tons ("GtC" stands for gigatons of carbon; figures are circa 2004). The purple numbers indicate how much carbon moves between reservoirs each year. The sediments, as defined...

In the ternary diagram of sp3 covalent carbon, sp2 covalent carbon and hydrogen, they belong to different regions [175]. Among them, ta-C has a large number of carbon atoms bonded into tetrahedron by sp3 bond, which is similar to diamond in properties and can be used in electronic devices...
