perhaps the more interesting nanostructures with large application potential, from transistors to probes, are carbon nanotubes. one of the most widely uses of these nanostructures are their applications as gas detector, which is an important application in the field se of environmental technologies. the present work studies the adsorption of carbon monoxide on a (6, 6) armchair carbon nanotube ...

the electronic absorption spectral line shape of a diatomic molecule with harmonic potential curves is calculated using the time correlation function formalism. both the equilibrium shift and the frequency shift of the two linking electronic states ate taken into account. the spectrum is also calculated using the cumulated expansion which is related to the correlation function of the time-depen...

the purpose of this paper is to introduce the concept of l-fuzzybilinear operators. we obtain a decomposition theorem for l-fuzzy bilinearoperators and then prove that a l-fuzzy bilinear operator is the same as apowerset operator for the variable-basis introduced by s.e.rodabaugh (1991).finally we discuss the continuity of l-fuzzy bilinear operators.

background: migraine is a neurovascular disorder and any interventions improving endothelial function may contribute to its treatment and prevention of vascular complications like ischemic stroke. yoga has been shown to have several beneficial effects on cardiovascular systems. however, no randomized controlled studies to date have investigated its effects on endothelial function of migraineurs...

In this study, Polyaniline molecule (emeraldine base) is modeled as a molecular wire and the effects of the metal/molecule coupling strength and the molecule length on the current-voltage (I-V) characteristics are numerically investigated. Using a tight-binding Hamiltonian model, the methods based on Non-equilibrium Green’s function theory, Landauer formalism and Newns-Anderson model, our calcu...

background: this study attempted to determine the effects of long-term use of vitamin c on vascular endothelial function. materials and methods: during a pilot clinical trial study conducted at imam hussein hospital (isfahan) in 2014-2015, a total of 40 diabetic patients were selected and then assigned randomly into two 20-subject groups receiving vitamin c and placebo tablets. the patients wer...

Making use of a generalized Green’s function technique and Landauer formalism, the temperature depended current-voltage (I-V) characteristics of C60 molecule, sandwiched between two metallic electrodes are numerically investigated. In addition, the influence of the electron-phonon coupling strength on the electronic properties of the molecule is studied. The I-V characteristics of the molecule ...

electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. an electro-active redox molecule comprises the main part of the electrochemical-based sensors. ferrocene is one of the most popular redox molecule used in biosensor fabrication. but, instability of ferrocenium ion in strong nucleophilic reagents and...
