Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

Advanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

An Improved Fault-Tolerant Control Strategy for High-Power ANPC Three-Level Inverter Under Short-Circuit Fault of Power Devices

IEEE Access, 2019
The high-power active neutral-point clamped (ANPC) three-level inverter has high-reliability requirements for the system operation, and short-circuit fault, very common, and serious problem in the operation will affect the operation stability.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Calculation and Analysis of the Strands Short-Circuit in Stator Transposition Bar for Large Generators

IEEE Access, 2019
The transposition of the stator bar is an important technique in the large generator design. Under the excitation of vibration and thermal effect, the insulation of strand is easily damaged, which leads to short-circuiting fault, and adversely impacts ...

Fault-Tolerant Control for Single-phase Open-circuit and Short-circuit Fault in Five-phase PMSM with Third-order Harmonic Back EMF Using Coefficients Reconfiguration

For a five-phase permanent magnet synchronous machine (PMSM), the third-order harmonic back EMF is increased by changing the shape of the permanent magnet for increasing average torque in healthy operation.
