Abstract Thermochemical cycle is a promising way for hydrogen production. Although the Gibbs free energy function has been used to assess thermochemical cycle reactions, it is difficult to explain exergy transfer and degeneration. There is no universal principle to explain the mechanism of triggering an endothermic reaction from the viewpoint of ...

Tunneling spectroscopy of Andreev energy levels in a quantum dot coupled to a superconductor.
Physical Review Letters, 2010The coupling of a quantum dot with a BCS-type superconducting reservoir results in an intriguing system where low energy physics is governed by the interplay of two distinct phases, singlet and doublet. In this Letter we show that the spectrum of Andreev

Energy levels of exciton in a gapped graphene sheet
, 2013A theory is presented for exciton formation in a graphene sheet using the center-of-mass approximation. The energy levels and wavefunctions of exciton are calculated analytically which show that the exciton can form if the band gap of graphene is not ...

Patients with skipped-level disk degeneration (SLDD) were recently reported as having a higher prevalence of Schmorl's nodes than patients with contiguous multi-level disk degeneration (CMDD). Fourteen versions of a nonlinear finite element model of a lumbar spine, representing different patterns of single and multi-level disk degeneration, were ...

The fluoroborane (HBF) free radical has a large vibronic interaction which splits the orbitally degenerate (2)Pi state in the linear configuration into two separate electronic states, one strongly bent and one linear.

A theoretical approach to study ro-vibrational molecular states from a full nuclear Hamiltonian expressed in terms of normal-mode irreducible tensor operators is presented for the first time. Each term of the Hamiltonian expansion can thus be cast in the

Convergence study of the 1/Z expansion for the energy levels of two-electron atoms
, 2010We perform numerical analysis of the first 20 and 14 coefficients for 1 {sup 1}S and 2 {sup 3}S states of the 1/Z expansion of the energy of two-electron atoms, respectively.

A general solution of the exchange problem in the high-nuclearity spin clusters (HNSC) containing arbitrary number of exchange-coupled centers and topology is developed. All constituent magnetic centers are supposed to possess well-isolated orbitally non-
