Pleased to share our recent collaborative work on critical mineral and material engineering, focusing on dysprosium (Dy)-bearing permanent magnets. These magnets are essential components for hybrid electric vehicles and wind turbines. This work is available at https://lnkd.in/g7-WG9Be. The precise modulation of the intergranular phase is essential for attaining high coercivity in permanent magnets and is strongly influenced by the alloying of solute atoms such as Copper (Cu) and Gallium (Ga). In this work, we propose and validate an intergranular phase transformation pathway from the typical rare earth (RE)-rich cubic phase to the beneficial RE?(Fe,Cu,Ga)?? phase through the design of complex heat treatment workflows, detailed microscopy characterisation, and computational simulations. This provides valuable insights into the optimisation of phase distribution to further enhance coercivity. This work builds upon our previous research https://lnkd.in/gAcRRruT. Greatly appreciate the strong support from Professor Simon Ringer Simon Ringer, Sydney Microscopy & Microanalysis (https://lnkd.in/gmTRr4Aj), and the University of Sydney node of Microscopy Australia Microscopy Australia.

Dysprosium-bearing magnets are emerging as a critical material in the net zero revolution, with major applications in wind turbines and hybrid electric vehicles. In this paper Hansheng Chen and team used atomic-scale imaging at our University of Sydney facility, Sydney Microscopy & Microanalysis, to provide important insights to improve the stability of these magnets for high-temperature applications such as in wind turbines and cars. #NCRISimpact

?? Excited to share our new publication on a novel technique for improving magnetic plucking in piezoelectric energy harvesters, available online on Meccanica #Springer. We developed a technique using shielded Neodymium-iron-boron magnets polarized in opposite directions on a main magnet. This breakthrough significantly improves the efficiency of frequency up-conversion in piezoelectric energy harvesters compared to traditional approaches. In our study, we conducted both computational and experimental investigations, demonstrating how this technique is highly useful in the field of low-speed and low-frequency vibration energy harvesting. Additionally, our findings have promising applications in actuation and sensing technologies. I would like to thank my co-authors for the great collaboration and the enthusiasm we shared in this work!

?? ?? ?? Paper of the Day ? ? ? MXene-based multilayered and ultrawideband absorber for solar cell and photovoltaic applications Today’s paper of the day discusses development of an ultrawideband solar adsorber using MXene-based metamaterials designed for photovoltaic and solar cell applications. The structure composed of materials like MXene, SiO?, MgF?, and tungsten demonstrates over 80% absorption efficiency across a wide frequency range (100–2500 THz), including UV, visible, and infrared spectra. The study includes absorption stability at oblique angles, high absorption rates (>99%), and a multilayered design optimized for energy harvesting. The study explores the impact of layer thickness, resonator sizes, and material configurations by numerical simulations. #Ultrawidebandsolarabsorber? #Photovoltaics #Solarcells #Metamaterials #Energyharvesting #Sustainableenergy #Researcharticle #Openaccess #SOL #Scienceoflives #Paperoftheday #POD Date: 16/01/2025 For more, click the link below https://lnkd.in/gxW49ta4 For more, click the link below https://lnkd.in/gmJuz4eC

I am pleased to announce that my paper, "Fracture Analysis of a Cycloidal Gearbox as a Yaw Drive on a Wind Turbine," has been referenced by Dr. HD Tran et al. in their work, "Application of the TOPSIS Method for Multi-Objective Optimization of a Two-Stage Helical Gearbox," published this month in the "Engineering, Technology, and Applied Science Research journal, volume 14, issue 4, 2024. This citation, which is the second for this paper only this year, is a testament to the recognition and respect research has garnered in this domain. #research #renewables # fracture Analysis
