High-Performance Na-Ion Storage of S-Doped Porous Carbon Derived from Conjugated Microporous Polymers

Nano-Micro Letters, 2019
Na-ion batteries (NIBs) have attracted considerable attention in recent years owing to the high abundance and low cost of Na. It is well known that S doping can improve the electrochemical performance of carbon materials for NIBs.

Mid-range adiabatic wireless energy transfer via a mediator coil

, 2012
A technique for efficient mid-range wireless energy transfer between two coils via a mediator coil is proposed. By varying the coil frequencies three resonances are created: emitter-mediator (EM), mediator-receiver (MR) and emitter-receiver (ER).

Manganese Ferrite Nanoparticles (MnFe₂O₄): Size Dependence for Hyperthermia and Negative/Positive Contrast Enhancement in MRI

Nanomaterials, 2020
We synthesized manganese ferrite (MnFe2O4) nanoparticles of different sizes by varying pH during chemical co-precipitation procedure and modified their surfaces with polysaccharide chitosan (CS) to investigate characteristics of hyperthermia and magnetic

Fermion resonance in quantum field theory [PDF]

, 2006
We derive accurately the fermion resonance propagator by means of Dyson summation of the self-energy contribution. It turns out that the relativistic fermion resonance differs essentially from its boson analog.Comment: 8 pages, 2 figures, revtex4 class ...

Structure of positive energy states in a deformed mean-field potential

, 2003
We investigate the properties of single-particle resonances in a non-spherical potential by solving the coupled-channels equations for the radial wave functions.

Relativistic Configuration-Interaction Photoionization Data for Ne-Like Isoelectronic Sequence

East European Journal of Physics
Photoionization data for the 1s2 2s2 2p6 (1S0) ground state of neon like Ca10+, Sc11+, Ti12+, V13+, and Cr14+ ions are reported. The values of ionization threshold limits, resonance energies, quantum defects, transition rates, and oscillator strengths ...

Resonance refraction and neutrino oscillations

Journal of High Energy Physics, 2021
The refraction index and matter potential depend on neutrino energy and this dependence has a resonance character associated to the production of the mediator in the s−channel.

Study of the 12C+12C fusion reactions near the Gamow energy [PDF]

, 2007
The fusion reactions 12C(12C,a)20Ne and 12C(12C,p)23Na have been studied from E = 2.10 to 4.75 MeV by gamma-ray spectroscopy using a C target with ultra-low hydrogen contamination. The deduced astrophysical S(E)* factor exhibits new resonances at E
