With the presence of CO adsorbed on metal surfaces of metal–TMO interfaces, hydroxyl groups on TMO surfaces of metal–TMO interfaces can react with CO to produce CO2 accompanied by the creation of surface Ovs and the migration of H adatoms to neighboring surface lattice oxygen. It is ...
Crystalline (Fig. 1.12)A crystal or crystalline solid is a solid material, the constituent atoms, molecules, or ions for which are arranged in an orderly repeating pattern extending in all three spatial dimensions. During crystallization, in which there is enough space for their uninterrupted growth...
We demonstrate computationally that the σ-hole concept and the outer regions of positive electrostatic potential account for the existence, directionalities and strengths of the observed noncovalent interactions. 展开 关键词: Directional noncovalent interactions Electrostatic potentials Group VI atoms σ-...
When a second atom is adsorbed, in both cases, there is a strong preference of the two atoms to dimerize. However, the orientation and position of the ad-dimer is determined by the binding site of the first atom. The formation of the long lines in the case of group III and not for ...
Certain elements have the property of producing the same crystal form when in combination with an equal number of atoms of one or more common elements, and the elements, from his point of view, can be arranged in certain groups. For convenience I have called the elements belonging to the ...
The Reaction of Some N-(Nitrophenyl)azoles With Alkali: Preparation of the Corresponding Azoxybenzenes. X-Ray Structure of 2,2′-Bis(1″,2″,4″-triazol-1... The benzene ring atoms are coplanar to within experimental error, as are the triazole ring atoms, and the dihedral angle between ...
full nonrigid (f-NRG) group of 1,3,5-trimethylbenzene (TMB) is shown to be isomorphic to the group S3[C3] = C3 S3 of order 162, where denotes the wreath product of groups, and C3 is the cyclic group of order three and S3 is the symmetric group of order six on three letters. ...
The process therefore involves oxidative coupling at the benzylic carbon atoms. The di-nitrones (3) have in fact been isolated on treatment of the nitrones (1) or their cyclic dimers (2) with oxygen. The N,N′-dialkyl dinitro... Francesco,de,Sarlo,Alberto,... - 《Journal of the Chem...
