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...
A series of neutral rare-earth metal amides containing different achiral and chiral heteroscorpionate ligands was synthesized and characterized and these compounds were employed in the polymerization of cyclic esters. Thus, treatment of [Ln{N(SiHMe(2))(2)}(3)(thf)(2)] (Ln = Nd, Sm) with acetamide or thioacetamide heteroscorpionate ligands for 2 h at 0 °C afforded the α-agostic silylamido dimeri...
