We studied the preparation and measured the properties of PbO- MgO-Nb sub 2 O sub 5 ceramics near the Pb(Mg sub 1/3 Nb sub 2/3) O sub 3 composition including effects of PbTiO sub 3 dopant.

Reduced ternary molybdenum oxides, particularly those containing an alkali metal as the ternary element, exhibit a wealth of structural complexity and a variety of physical phenomena including char

Multiple metal-target d.c.

We have prepared bulk and thin film Ta(2)O(5) by the sol-gel process. Thin film Ta(2)O(5) is prepared by spin-coating Si wafers when Ta(2)O(5) is in the form of sols.

The electrochemical reduction of molten Li-Na-K carbonates at 450 degrees C provides ``quasi-spherical{''} carbon nanoparticles with size comprised between 40 and 80 nm (deduced from AFM measuremen

Ultrafine copper particles were prepared in a poly(2-vinylpyridine) matrix by the thermal decomposition of a copper formate-poly (2-vinylpyridine) complex.

By using newly constructed high-pressure gas atomization equipment, the effect of atomizing gas (Ar,N sub 2, or He) on the formation tendency of amorphous alloy powders and their Curie temperature

Preparation of glass articles by sintering of glass and amorphous powders is considered.

We have prepared superconducting thin films of (Y,Yb)Ba sub 2 Cu sub 3 O sub (7-delta) by evaporation of copper, ytterbium or yttrium, and barium fluoride from Knudsen effusion cells.

High T sub c and J sub c superconducting films of Ba sub 2 YCu sub 3 O sub 7 are prepared on (100) SrTiO sub 3 substrates using pulsed excimer laser vaporization of a composite target containing B
