Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries
Advanced Functional Materials, EarlyView.A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Direct Torque Control using switching table for induction motor fed by Quasi Z-Source Inverter
, 2017 Z-source inverters eliminate the need for front-end DC-DC boost converters in applications with limited DC voltage such as solar PV, fuel cell. Quasi Z-source inverters offer advantages over Z-source inverter, such as continuous source current and lower ...

Advanced Functional Materials, EarlyView.Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Time‐Resolved Magnetization Switching Dynamics Driven by Orbital Torques
Advanced Functional Materials, EarlyView.Du et al. reveal nanosecond magnetization switching driven by orbital currents using time‐resolved Hall detection. The measurements separate domain nucleation from domain wall propagation and show that Joule heating strongly assists switching by lowering energy barriers.

Advanced Functional Materials, EarlyView.Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Modified Quasi-Z-Source Inverter with Model Predictive Control for Constant Common-Mode Voltage
, 2019 The common-mode voltage (CMV) of transformerless inverters in photovoltaic system should be properly addressed. The conventional CMV reduction methods for voltage source inverters should be modified when applied to the quasi-Z-source inverters with shoot-
