Nanometer Al2O3 particles were added to (Bi, Pb) 2Sr2Ca2Cu3Ox (Bi-2223) precursor
powders during the final sintering cycle of a multi-step preparation process. The influence of …

With the advent of High Temperature Superconductivity and the increasing reliability of
fabrication techniques, superconductor technology has moved firmly into the mainstream of …

We performed a deep infrared imaging survey of 63 embedded young stellar objects (YSOs)
located in the Taurus and Ophiuchus clouds to search for companions. The sample includes …

The evolution of the phase formation and microstructure in (Bi, Pb)–Sr–Ca–Cu–O
(BPSCCO) superconducting materials have been studied through a two-cycle annealing …

Since the discovery of high temperature superconductors the scientific com nmnity has been
very active in research on material and system development as well as on the basic …

Reactions occurring in Ag-sheathed Bi, Pb (2223) monofilamentary tapes have been studied
in situ using high-temperature neutron diffraction. A neutron compatible furnace enabled us …

Processing (Bi, Pb)/sub 2/Sr/sub 2/Ca/sub 2/Cu/sub 3/O/sub x/(Bi-2223) tape by the oxide-
powder-in-tube technique normally includes two heat treatments and one intermediate …

Spherical and fine BSCCO precursor powders were prepared by an ultrasonic spray
pyrolysis (SP) method from an aqueous solution of metal nitrates. The synthesized precursor …

The correlation between reaction kinetics of the Bi (Pb)-2223 phase and critical current
density in Bi (Pb)-2223/Ag tapes has been analysed. It has been found that a slow formation …

The structural and superconducting properties of high-Tc compounds are investigated by
use of hard x-ray diffraction and neutron diffraction, magnetooptical imaging, susceptibility …
