An In-Phase Unit Slot-Opening Shift Method for Cogging Torque Reduction in Interior Permanent Magnet Machine

Mathematics, 2023
The cogging torque reduction methods in permanent magnet (PM) machines are more or less FEA trial and error-based and cause undesirable side effects, such as distorted back EMF, new harmonic components, and structure asymmetry.

Molecular Photogearing for Controlling Rotary Motion at the Nanoscale

ChemPlusChem, Volume 91, Issue 4, April 2026.
Molecular gears capable of controlling and transmitting rotary motion at the nanoscale are indispensable for the construction of artificial molecular machines. In this concept, we discuss how molecular photogears featuring a propeller‐shaped motif attached to a light‐driven molecular motor offer new possibilities to perform these tasks with better ...

Ipriflavone From Aquilaria malaccensis Lam. Exosome‐Like Nanoparticles Targets Prolyl Hydroxylase Domain Protein 2 (PHD2) to Enhance Hypoxia‐Inducible Factor‐α (HIF‐α) Hydroxylation Thereby Alleviating Hypoxia‐Induced Gastrointestinal Mucosal Ferroptosis

MedComm, Volume 7, Issue 4, April 2026.
Ipriflavone (Ipr), an active component of Aquilaria malaccensis Lam. exosome‐like nanoparticles (AELNs), significantly reduces hypoxia‐inducible factor‐α (HIF‐α) expression by enhancing the prolyl hydroxylase domain protein 2 (PHD2)‐mediated hydroxylation of HIF‐α, thereby downregulating HIF‐α‐induced polyunsaturated fatty acid‐phospholipids (PUFA‐PLs),

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...
