A pearlescent effect pigment having an opaque, dark or black color is disclosed. The black pearlescent pigment includes a platelet-shaped non-metal substrate, optionally an oxide layer, a template layer, and a metal layer. The pearlescent luster of the disclosed effect pigment is comparable to those of pure pearlescent effects. The disclosed method provides a cost-effective approach for the manufacturing of the disclosed effect pigment.

A hydrogen detector with a porous layer of alumina. Pores with average pore diameters in the range of from about 10 to about 200 nanometers (nms) and average pore depths in the range of from about 10 to about 1000 nms have Pd nanoparticles in the pores forming a film. Electrodes on the Pd film measure changes in electrical resistance of the Pd film in the presence of hydrogen. Pd may be in the form of nanotubes. The alumina is anodized for various times to form the nanowalls or pores and vary the pore depths.
