Here we present the first vertical distribution of dissolved (D) and acid-dissolvable (AD) bioactive trace metals (Fe, Co, Ni, Cu, Zn and Cd) in the Sulu Sea and the South China Sea, together with those observed previously by the same method in the w

Dielectric properties of filled epoxy resins were measured after water attack at 50/spl deg/C and after HF vapors attack. The loss tangent tan /spl delta/ of these composites showed tendency to increase rapidly from moisture content 0.6%. But roundis

We have observed three dimensional space charge profiles of an epoxy resin sheet with internal wires and of a polyimide flexible printed circuit board. Experimental results suggest that the three-dimensional pulsed electroacoustic (3D-PEA) space char
