Two non-isostructural homometallic 1D neodymium species displaying field-induced slow magnetization relaxations are presented together with theoretical studies. It is established that both systems are better described as organized 1D single molecule magnets (SMMs). Studies show great potential of Nd(III) ions to provide homometallic chains with slow magnetic relaxation.
Abstract The heat capacity of bismuth cobalt oxides doped by neodymium and holmium was measured for the first time differential scanning calorimetry in temperature range 319-1000 K.
A 53 year old woman with respiratory failure and stridor caused by a tracheal plasmacytoma was treated by endoscopic loop polypectomy and neodymium YAG laser therapy, followed by local irradiation. Two years later there was no evidence of recurrence of disease.
Post-neodymium magnets that possess high heat resistance, coercivity, and (BH)max are desired for future-generation motors. However, the candidate materials post-neodymium such as Sm2Fe17N3 metastable magnetic alloys have certain process-related problems: low sinterability due to thermal decomposition at elevated temperatures, deterioration of coercivity during sintering, poor raw powder. Vario...
A rapid and sensitive immunoassay for the determination of vitellogenin (Vg) is described. The method involves a sequential injection analysis (SIA) system equipped with an amperometric detector and a neodymium magnet. Magnetic beads, onto which an antigen (Vg) was immobilized, were used as a solid support in an immunoassay. The introduction, trapping and release of magnetic beads in an immunor...
