Rare earth elements (REEs), particularly dysprosium (Dy), are critical for development of future clean energy technologies. However, their recovery from end-of-life (EOL) NdFeB magnets faces significant challenges and has not been widely implemented at the industrial scale. Improving resource efficiency requires the development of recycling and recovery methods for REEs from EOL waste using...

Sodium-ion batteries (SIBs) offer an efficient energy storage solution for large-scale applications. Na4Fe3(PO4)2P2O7 (NFPP) is recognized as a promising candidate for electrode material in SIBs: it is able to intercalate reversibly up to 3 moles of Na ions. The main disadvantage of NFPP is its very low electronic conductivity, which hinders the Na+ mobility. To increase NFPP conductivity, a...

The utilisation of organic electrode materials (OEMs) as versatile redox-active hosts for lithium- and sodium-ion batteries is a recent development. The popularity of these materials is driven by their tunability, sustainability, and capacity to store both cations and anions within one framework. The structural flexibility inherent to these substances renders them far less sensitive to the...

Sodium-ion batteries are a promising alternative to lithium-ion batteries. They use sodium, which is less expensive than lithium. However, developing high-capacity, stable anode materials is challenging. Zinc oxide (ZnO) has a wurtzite structure and a high theoretical capacity, but it exhibits poor conductivity during charge/discharge cycles and undergoes fast degradation. However, his ZnO...

GdMn0.5M0.5O3 (M = Cr, Fe, Co) double perovskites were synthesized via a glycine-assisted solution combustion method. Phase purity and crystal structure were confirmed by powder X-ray diffraction, while Rietveld refinement established the formation of single-phase orthorhombic structures within the Pnma space group, and Z = 4. Structural analysis revealed significant octahedral distortions,...

Laser-induced breakdown spectroscopy (LIBS) was employed to investigate plasma characteristics and matrix-induced analytical effects in hydrophilic chia (Salvia hispanica L.) seeds. Owing to their gel-forming polysaccharide matrix, chia seeds represent a structurally complex material that can significantly influence plasma formation and emission stability. Pressed pellet samples were analyzed...

This work builds on the previous study, which documented the initial detection of metallic impurities (vanadium and possibly Fe and Cu) in commercially available argon gas supplied in steel cylinders 1. In the present study, the laser-induced gas plasma was spectroscopically analyzed over the spectral range 250-550 nm in argon (5.0), helium (4.6), and air at atmospheric pressure. Because...
