Novel strategy for one-step production of attenuated Ag-containing AgCu/ZnO antibacterial-antifungal nanocomposite particles
(Springer, 2020)
Novel strategies have been developed to comply with Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulations to provide the same performances for antibacterial and antifungal materials. The ...
Fabrication and characterization of Yb-doped Y2O3 powders and thin films
(Carl Hanser Verlag, 2020)
Yttrium oxide (Y2O3) and ytterbium (Yb)-doped Y2O3 particles were synthesized via the sol-gel method from the aqueous solution of their nitrate salts. The synthesized powders were then deposited on Corning glass substrates ...
New proposal for size and size-distribution evaluation of nanoparticles synthesized via ultrasonic spray pyrolysis using search algorithm based on image-processing technique
(Mdpi, 2020)
Nanoparticle properties are correlated to their size, size distribution, and shape; it is essential to accurately measure these features in the field of nanoscience. In this study, silver nanoparticles (AgNPs) were synthesized ...
A straightforward approach for the synthesis of nanostructured Y2O3 particles: synthesis, morphology, microstructure and crystal imperfection
(Elsevier, 2020)
A facile and straightforward approach has been implemented for the synthesis of nanostructured Y2O3 particles via sol-gel method from yttrium nitrate solution. The individual effects of calcination temperature, ...
Recovery of rare earth elements through spent NdFeB magnet oxidation (first part)
(MDPI-Multidisciplinary Digital Publishing Institute, 2022)
Due to their remarkable magnetic properties, such as a high maximum energy product, high remanence, and high coercivity, NdFeB magnets are used in a variety of technological applications. Because of their very limited ...
Recovery of rare earth elements from spent NdFeB-magnets: separation of iron through reductive smelting of the oxidized material (second part)
(MDPI-Multidisciplinary Digital Publishing Institute, 2022)
This paper proposes a pyrometallurgical recycling method for end-of-life NdFeB magnets by oxidizing them in air and subsequently smelting them. The smelting process enabled the recovery of rare earth elements (REEs), ...

NdFeB magnets are employed in various technological applications due to their outstanding magnetic properties, such as high maximum energy product, high remanence and high coercivity. Production of NdFeB has gathered more ...
NdFeB Magnets recycling process: an alternative method to produce mixed rare earth oxide from Scrap NdFeB Magnets
(MDPI, 2021)
Neodymium iron boron magnets (NdFeB) play a critical role in various technological applications due to their outstanding magnetic properties, such as high maximum energy product, high remanence and high coercivity. Production ...
Hydrometallurgical recycling of waste NdFeB magnets: design of experiment, optimisation of low concentrations of sulphuric acid leaching and process analysis
(Taylor & Francis, 2022)
Efficient recovery of rare earth elements (REEs) from scrap NdFeB magnets is a significant requirement for a circular economy. Therefore, the development of a cost-effective and environmentally friendly leaching process ...
