摘要:Abstract(#br)In the past two years, the record of current carrying capacity of Bi 2 Sr 2 CaCu 2 O x (Bi-2212) wire has been broken many times by using improved powder, which shows that the precursor powder plays an important role in the preparation of Bi-2212 wire. In order to im...

摘要:Abstract(#br)In order to solve the problem of excessive porosity of Bi-2212 Cable in Conduit Conductor (CICC) after the overpressure heat treatment, which leads to a significant decrease of mechanical stability of the conductor, a pre-annealing of Bi-2212 wires with a total ...

摘要:Abstract(#br)The voids in Bi 2 Sr 2 CaCu 2 O x (Bi-2212) long-length wire should be eliminated as far as possible in order to improve its current-carrying capacity. There are several reasons for the void formation in Bi-2212 wire, mainly including the gas adsorbed on powder and e...

摘要:Abstract(#br)The phase assemblage of precursor powder was controlled by changing the calcination temperature from 830 to 860 °C. The microstructure and the critical current density of tapes were strongly dependent on the phase composition of the precursor powder. SEM analysi...

摘要:Abstract(#br)The multifilamentary (Bi,Pb)-2223 tapes with Ag-alloy sheath were fabricated by powder-in-tube method. Critical current density ( J c ) of the tape reached 3 × 10 4 A/cm 2 at 77 K, self-field, and the tensile strain enhanced to about two times of the pure Ag-she...

摘要:Abstract(#br)Precursors prepared by mixing (Bi,Pb)-2212 and CaCuO 2 have been successfully used in the synthesis of high quality Bi-2223/Ag tapes. The effect of excess CaCuO 2 , over a range between −5 and 15 at.%, on the properties of monofilamentary Bi-2223/Ag tapes has be...

摘要:Abstract(#br)Long-term treatment with cyclosporine A (CsA) is associated with various types of complications; however, CsA-induced anemia has not been reported. The present study examined the impact of CsA on hematopoietic parameters and intrarenal expression of erythropoiet...

摘要:Abstract(#br)Insulin resistance has been proposed to play a pivotal role in vasoconstriction due to increased oxidative stress. Hyperthyroidism would amplify cardiovascular disease risk in diabetic patients, though thyroid hormone advance vascular relaxation and reduce vascu...

摘要:Abstract(#br)Adipogenesis, the development from preadipocytes or mesenchymal stem cells (MSCs) to mature adipocytes, is regulated by a network of signaling pathways and transcription factors. The involvement of Notch signaling and its effector HES1 in adipogenesis has been invest...
