Activation of the Cyano Group at Imidazole via Copper Stimulated Alcoholysis

open access: yesInorganics, 2019
Reactions of 4,5-dicyano-1-methylimidazole with CuX2 (X = Cl, Br) in alcohol solvents (ethanol and methanol) resulted in the formation of Cu(II) carboximidate complexes [CuCl2(5- cyano-4-C(OEt)N-1-methylimidazole)(EtOH)] (1), [Cu2(µ-Cl)2Cl2(5-cyano ...

QM(DFT) and MD studies on formation mechanisms of C_(60) fullerenes [PDF]

open access: yes, 2000
One of the most puzzling aspects of fullerenes is how such complicated symmetric molecules are formed from a gas of atomic carbons, namely, the atomistic or chemical mechanisms. Are the atoms added one by one or as molecules (C2, C3)? Is there a critical

Dirac point resonances due to atoms and molecules adsorbed on graphene and transport gaps and conductance quantization in graphene nanoribbons with covalently bonded adsorbates

open access: yes, 2011
We present a tight binding theory of the Dirac point resonances due to adsorbed atoms and molecules on an infinite 2D graphene sheet based on the standard tight binding model of the graphene p-band electronic structure and the extended Huckel model of ...

Electronic structure of mesoionic compounds. The classification problem

open access: yesВісник Харківського національного університету: Серія xімія
Mesoionic compounds are conventionally categorized into two types based on the primary origin of electrons within the conjugated system, specifically determined by the arrangement of heteroatoms in the five-membered ring.

Methods of cumulative quantum mechanics for describing the interaction of electromagnetic fields with matter in Vysikaylo large standing nanoscale excitons: Hydrogen-like atoms, molecules, surfaces, and twinkling crystals [PDF]

open access: yesNanotechnology and Precision Engineering
Using cumulative quantum mechanics (CQM) and the method of generalized mathematical transfer (MGMT), we analytically study quantum nanometer cumulative-dissipative structures (CDS) and the forces arising within them, which focus nanostructures into ...

Unravelling the Chemistry of the [Cu(4,7-Dichloroquinoline)2Br2]2 Dimeric Complex through Structural Analysis: A Borderline Ligand Field Case

open access: yesCrystals, 2020
Large dark prismatic crystals (P 1 ¯ ) consisting of closely packed centrosymmetric [Cu(4,7-dichloroquinoline)2]2Br4 binuclear units are formed when 4,7-dichloroquinoline (DCQ, C9H5NCl2) binds copper(II).

Feynman Diagrams for Dispersion Interactions Out of Equilibrium -- Two-Body Potentials for Atoms with Initial Excitation

open access: yes, 2011
Diagrammatic techniques are well-known in the calculation of dispersion interactions between atoms or molecules. The multipolar coupling scheme combined with Feynman ordered diagrams significantly reduces the number of graphs compared to elementary ...

Comparative study of cavitands-based nanocapsule as a drug delivery vehicle for an anti-cancer and multiple sclerosis drug—A DFT study

open access: yesRoyal Society Open Science
Nanoscale-assisted drug delivery systems give a platform to alter elementary properties associated with drug particles to limit their adverse effects. In this regard, deep benzimidazolone cavitand-based dimeric nanocapsule, which can act as good host for
