1. SUPRAS has extensively described the temperature behaviour of the electrical
resistance in the presence of a small magnetic field.
2. SUPRAS has extracted the behavior of superconductivity fluctuations from
room till percolation temperature in the electrical resistivity and the thermoelectric
power of various ceramics.
3. SUPRAS has developed theoretical models for thermal conductivity in the
presence or absence of a magnetic field, over the whole temperature range
and shown the likeliness of a d-wave order parameter.
4. SUPRAS probably has the most precise measurements of the Seebeck and Nernst
effects for above, in the vicinity of and below the superconductivity transition.
5. SUPRAS probably has the most precise technique for simultaneous measurements
of the Seebeck effect and thermal conductivity.
6. SUPRAS has investigated particular substitutions: Li, Na, K, Cs (for Ba),
S (for O) , and Bi (for Y) in Y1Ba2Cu3O7-x , Pb in BiSrCaCuO, and RE substitution
for texturing enhancement.
7. SUPRAS has performed the sintering of textured ceramics, both of YBCO
and BiSrCaCuO type in a magnetic field, and simulated the crystal growth.
8. SUPRAS has developed the glassy matrix precursor route to synthesize BiSrCaCuO
compounds.
9. SUPRAS has obtained very high critical current density in bulk textured
materials.
10. SUPRAS has simulated and described the growth of melt textured ceramics
of YBCO-type in a magnetic field.
11. SUPRAS has shown the likeliness of a d-wave order parameter through transport
properties measurements and theory.
12. SUPRAS has developed a technique for seed melt texturing of large single
areas.
13. SUPRAS probably has the most precise technique for simultaneous measurements
of the Seebeck effect, thermal diffusivity and thermal conductivity.
14. SUPRAS has found a simple cause of and developed a simple model to
explain Giant Magneto Resistance (GMR) effects in manganate compounds
