One of the key technological challenges in the development of iron-oxide-based magnetic nanoparticles (MNPs) is their long-term physical stability in colloidal dispersions. This can be improved by their transformation into a dry form. Here, we introduce electrospinning as a drying method for ethanol-based and water-based MNP dispersions, which enab...
It is widely recognized that in the transition from conventional electrical power systems (EPSs) towards smart grids, electrical voltage frequency will be greatly affected. This is why this research is extremely valuable, especially since rate-of-change-of-frequency (RoCoF) is often considered as a potential means of resolving newly arisen problems...
The majority of the clinically approved iron oxide nanoparticles (IO NPs) used as contrast agents for magnetic resonance imaging (MRI) have been withdrawn from the market either due to safety concerns or lack of profits. To address this challenge, liposomes have been used to prepare IO-based T$_2$ contrast agents. We studied the influence of differ...
We report on the first observation of a magnetic transition in multiferroic ▫${rm Pb_5Cr_3F_{19}}$▫. The system undergoes a ferroelectric transition at ▫$T_C$▫ = 545 K and probably an antiferromagnetic transition around ▫$T_N$▫ = 11 K. Between 50 K and ▫$T_N$▫, the system is not paramagnetic but shows the presence of correlated spin clusters, indic...
