Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

open access: yesAdvanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

open access: yesAdvanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Parameter-Free Model Predictive Control of Five-Phase PMSM Under Healthy and Inter-Turn Short-Circuit Fault Conditions

open access: yesEnergies
Model predictive control offers high-performance regulation for multiphase drives but is critically dependent on the accuracy of mathematical models for prediction, making it vulnerable to parameter mismatches and uncertainties.

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Field-Oriented Control of Multiphase Drives With Passive Fault Tolerance

open access: yesIEEE Transactions on Industrial Electronics, 2020
Multiphase machines provide continuous operation of the drive with no additional hardware in the event of one or more open-phase faults. This faulttolerant capability is highly appreciated by industry for security and economic reasons. However, the steadystate post-fault operation has only been feasible in previous works after the fault localization ...

Doppler radar with multiphase modulation of transmitted and reflected signal [PDF]

open access: yes, 1989
A microwave radar signal is generated and split by a circulator. A phase shifter introduces a series of phase shifts into a first part of the split signal which is then transmitted by antenna.

Numerical Modeling of Multiphase, Turbulent Galactic Disks with Star Formation Feedback

open access: yes, 2012
Star formation is self-regulated by its feedback that drives turbulence and heats the gas. In equilibrium, the star formation rate (SFR) should be directly related to the total (thermal plus turbulent) midplane pressure and hence the total weight of the ...

Porosity Engineering of MXene Architectures: Toward High‐Performance Aqueous Electrochemical Energy Storage

open access: yesAdvanced Materials, EarlyView.
This review systematically summarizes recent advances in porosity engineering of MXenes, with a focused discussion on their structure‐governed energy storage properties. A critical analysis of structure–property relationships is presented across alkali‐ion batteries, multivalent‐ion batteries, and supercapacitors.

Symmetrical/Asymmetrical Winding Reconfiguration in Multiphase Machines

open access: yesIEEE Access, 2020
This paper investigates multiphase drives in which winding configuration (symmetrical or asymmetrical) can be easily obtained by only rearranging voltage source inverter (VSI) power supply cables at the machine's terminal box.
