Noise mitigation in dual three-phase internal permanent magnet machines by injection of current harmonics

open access: yesThe Journal of Engineering, 2019
Steadily increasing power demands are linked with the ongoing process of electrifying the powertrain for dominant and pure electric vehicles. Fulfilling those requirements can be achieved by a multiphase approach which is implemented with a six-phase ...

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

open access: yesAdvanced Functional Materials, EarlyView.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...

Modulating Oxide‐Based Quantum Materials by Ion Implantation

open access: yesAdvanced Functional Materials, EarlyView.
This review highlights how ion implantation, a well developed chip‐technology, enables targeted modulation of oxide‐based quantum materials. This includes tuning of metal‐insulator transitions, magnetism, and superconductivity through selective doping, defect creation, and induced lattice strain. Abstract Ion implantation has emerged as a powerful tool

Robotized FSW – Evolution of forces and torque with nonlinear welds [PDF]

open access: yes, 2014
The main purpose of the article is to study the evolution of the welding forces and torque with non-straight welding path. The main studies performed on forces and torque are usually done on plane straight welding path when the processing parameter are ...

A magnetic synapse: multilevel spin-torque memristor with perpendicular anisotropy

open access: yesScientific Reports, 2016
Memristors are non-volatile nano-resistors which resistance can be tuned by applied currents or voltages and set to a large number of levels. Thanks to these properties, memristors are ideal building blocks for a number of applications such as multilevel

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Energy Dissipation Rate in an Agitated Crucible Containing Molten Metal

open access: yesHigh Temperature Materials and Processes, 2017
The energy dissipation rate (EDR) is an important parameter for characterizing the behavior of inclusion coagulation in agitated molten metal. To clarify the inclusion coagulation mechanism, we review previous water model studies by particularly focusing

Field‐Free Spin–Orbit Torque Switching of Perpendicular Magnetization by PtTe2/WTe2 Bilayers at Sub‐ns Timescales

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates ultrafast, field‐free spin–orbit torque (SOT) switching using a PtTe2/WTe2/CoFeB multilayer, achieving sub‐nanosecond magnetization reversal with record‐low energy consumption. The PtTe2/WTe2 bilayer generates an intrinsic out‐of‐plane spin current, enabling deterministic switching without external fields.
