the fabrication of a non-doped red organic light-emitting device (oled) has been developed using naturally occurring curcumin as an emissive layer of oled. in this research, the electroluminescent spectrum (el) of curcumin as a donor-acceptor-donor (d-a-d) chromophore was obtained at wavelength of 612 nm. also, the maximum external quantum efficiencies (eqe) for this device was measured and fou...

A variety of nanomechanical systems can now operate at the quantum limit1–4, making quantum phenomena more accessible for applications and providing new opportunities for exploring the fundamentals of quantum physics. Such mechanical quantum devices offer compelling opportunities for quantum-enhanced sensing and quantum information5–7. Furthermore, mechanical modes provide a versatile quantum b...

Regarded as one of the most fundamental concepts classical mechanics and thermodynamics, work has received well-grounded definitions within quantum framework since 1970s, having being successfully applied to many contexts. Recent developments on concept have taken place in emergent field where is frequently characterized a stochastic variable. Notwithstanding this remarkable progress, it still ...

We consider (4+D)-dimensional Kaluza-Klein cosmological model with two scaling factors, as real, p-adic and adelic quantum mechanical one. One of the scaling factors corresponds to the D-dimensional internal space, and second one to the 4-dimensional universe. In standard quantum cosmology, i.e. over the field of real numbers R, it leads to dynamical compactification of additional dimensions an...

Cavity optomechanical systems with an enhanced coupling between mechanical motion and electromagnetic radiation have permitted the investigation of many novel physical effects. The optomechanical coupling in the majority of these systems is of dispersive nature: the cavity resonance frequency is modulated by the vibrations of the mechanical oscillator. Dissipative optomechanical interaction, wh...

nanopartmles have been used as an approach to improve the pharmacodynamic and phannacokinetie propertiesof various drues. amino acids have been considered to be useful to make such nano particles because ofthocompatithe and biodegradable characteristic. the quantum mechanical method that was chosen to analyze inethio hexa peptide nano ring]. the structure of some peptide nanorrigs as well as th...

The so-called Yang-Mills mechanics originates from Yang-Mills field theory under the supposition of the spatial homogeneity of the gauge fields. Since its introduction twenty years ago [1] this model has been studied extensively from different points of view [2] [13]. The model is known to exhibit stochastical behaviour at the classical level. In particular it has been shown for a simplified tw...

A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.

Topological analysis has been performed on the total electron density of the two forms of Ozonemolecule,C2V and D3H ,to investigate the nature of chemical bonds ,molecular structure , atomiccharges and electrical properties. While these concepts have been completely discussed usingclassical models the emphasize in this work is based on Quantum Theory of Atoms in Molecules(QTAIM). Because the D3...
