The structural study of the non-covalent interactions in ternary mixture benzylamine (BA), ethanol and benzene has been attempted through Density Functional Theory (DFT) calculation. optimized structure monomers (BA, benzene), BA dimer their complexes (BA-benzene, BA-ethanol, BA-ethanol-benzene) interaction energies are used to describe intermolecular interaction. In addition conventional H-bon...

In this work we study a generalized integrable biparametric family of 4-D isotropic oscillators. This family allows to treat, in a uni ed way, oscillators de ned by the potential given by Hartmann related with the benzene molecule and other ring shape ones. These potentials belong to two larger families of 3-D integrable Hamiltonian systems and have received a special attention since are relate...

A new method for the synthesis of unsymmetrical calix[4]arenes is described which involves the reaction of a diyne with a bis-carbene complex of chromium. This synthesis of calixarenes is unique in that it involves the formation of two of the four benzene rings of the calixarene and the macrocyclic ring of the calixarene in the same step. Thus, two of the four benzene rings of the calixarene ar...

Abstract Acenes, polyaromatic hydrocarbons composed of linearly fused benzene rings have received immense attention due to their performance as semiconductors in organic optoelectronic applications. Their appealing physicochemical properties, such extended delocalization, high charge carrier mobilities, narrow HOMO‐LOMO gaps and partially radical character the ground state make them very attrac...

The CYP2E1 protein belongs to the P450 enzymes family and plays an important role in the metabolism of small molecular and organic pollutants. In this study we generated CYP2E1 transgenic plants of Petunia using Agrobacterium rhizogenes K599. PCR analysis confirmed that the regenerated plants contained the CYP2E1 transgene and the rolB gene of the Ri plasmid. Southern blotting revealed the pres...

Werner syndrome (WS) is a rare autosomal progeroid disorder caused by a mutation in the gene encoding the WRN (Werner syndrome protein), a member of the RecQ family of helicases with a role in maintaining genomic stability. Genetic association studies have previously suggested a link between WRN and susceptibility to benzene-induced hematotoxicity. To further explore the role of WRN in benzene-...

Since the discovery of acetylene and benzene in protoplanetary nebulae under powerful ultraviolet ionizing radiation, efforts have been made to investigate the polymerization of ionized acetylene. Here we report the efficient formation of benzene ions within gas-phase ionized acetylene clusters (C2H2)n+ with n = 3-60. The results from experiments, which use mass-selected ion mobility techniques...

Anaerobic benzene oxidation coupled to the reduction of Fe(III) was studied in Ferroglobus placidus in order to learn more about how such a stable molecule could be metabolized under strict anaerobic conditions. F. placidus conserved energy to support growth at 85°C in a medium with benzene provided as the sole electron donor and Fe(III) as the sole electron acceptor. The stoichiometry of benze...
