An innovative quantitative synthetic method for preparing magnetite nanoparticles, iodine crystals and table salt was achieved by co-precipitation in aqueous solution using only one single iron (III) salt as a precursor. A 2 Fe (III):1 Fe (II) mole ratio was first attained in solution by reducing iron(III) using KI solution, followed by filtering the iodine formed and subliming it then ...

Laser powder bed fusion (L-PBF) presents a promising technique for producing neodymium–iron–boron (NdFeB) magnets. However, the magnetic properties of L-PBF-generated magnets remain inferior to those of their sintered counterparts. To address this, post-processing techniques, such as heat treatment, could enhance the magnetic properties of L-PBF …
