Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Entanglement of two dipole-couples qubits induced by a thermal field of a cavity with Kerr medium

Физика волновых процессов и радиотехнические системы, 2021
In the present work, we investigated the dynamics of two identical superconducting qubits interacting with the mode of the quantum electromagnetic field of a microwave coplanar cavity with a Kerr medium in the presence of an effective dipole-dipole ...

Light storage and control of photon-photon interactions in a cold Rydberg gas [PDF]

, 2013
The effect of strong interatomic interactions on an optical field stored in Rydberg states of a cold atomic gas is investigated. Due to their large dipole moments Rydberg atoms interact very strongly with each other.

Si-H vibrational mode on a H-Si(111)1 × 1 surface with hydrogen deficiency [PDF]

, 2013
We used a dipole coupling theory to calculate modulations of the Si-H vibrational mode on a H-Si(111)1×1 surface, and analyzed the observed optical sum frequency generation (SFG) spectra.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Optical properties of a disordered metallic film: local versus collective phenomena

New Journal of Physics, 2013
We apply the dual-variable approach to the problem of the optical response of a disordered film of metal particles with dipole–dipole interaction. Long-range dipole–dipole interaction makes the effect of spatial correlations significant, so that the dual-

Spin Excitations in Dissipative Ferromagnetic Nanoshells [PDF]

Журнал нано- та електронної фізики, 2016
In the paper, dipole-exchange radial-angular spin excitations in a spherical ferromagnetic nanoshell are investigated. For such excitations, a differential equation for the magnetic potential is found, with account for the magnetic dipole-dipole ...

Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,

Entanglement between atom interacting with a thermal field of a lossless cavity and a free atom

Физика волновых процессов и радиотехнические системы, 2018
In the present paper we studied the entanglement of a quantum system consisting of two dipole-coupled two-level atoms, one of which interacts with one-mode thermal field in a lossless cavity, and another is outside a cavity.

Electric Octupole-Dependent Contributions to Optical Binding Energy

Physics
Contributions to the radiation-induced dispersion energy shift between two interacting particles dependent on the electric octupole moment are calculated using a physical picture in which moments induced by applied fluctuating electromagnetic fields are ...
