Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Voltage and Current Excitation for Time-Harmonic Eddy-Current Problems [PDF]
SIAM Journal on Applied Mathematics, 2008 We give a systematic presentation of voltage or current intensity excitation for time-harmonic eddy-current problems. The key point of our approach resides in a suitable power law that permits us to understand the role of voltage excitation. We also shed light on the influence of the boundary conditions on the proposed formulations.

The Power Losses in Cable Lines Supplying Nonlinear Loads
Energies, 2021 This paper presents the skin effect impact on the active power losses in the sheathless single-core cables/wires supplying nonlinear loads. There are significant conductor losses when the current has a distorted waveform (e.g., the current supplying ...

Array of Josephson junctions with a non-sinusoidal current-phase relation as a model of the resistive transition of unconventional superconductors [PDF]
, 2010 An array of resistively and capacitively shunted Josephson junctions with nonsinusoidal current-phase relation is considered for modelling the transition in high-T$_c$ superconductors. The emergence of higher harmonics, besides the simple sinusoid $I_{c}\

Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Rotor Slot Permeance Harmonics under Distorted Air-Gap Flux Waveform for Cage Induction Motors [PDF]
, 1991 The air-gap flux waveform for a cage induction machine is not sinusoidal in shape and contains various harmonics, including the phase-belt harmonics, slot magnetomotive force (mmf) harmonics, slot permeance harmonics, and saturation harmonics.

Anomalous magnetotransport through reflection-symmetric artificial molecules
, 2013 We calculate magnetotransport oscillations in current through a triple-quantum-dot molecule, accounting for higher harmonics (having flux period h/ne, with n an integer).
