Abstract: The present invention includes a paint or coating composition comprising an organic pigment or dye complexed to the surface of a layered or fibrous inorganic clay. A wide variety of paint colors can be obtained by varying the pH during the preparation as well as by varying the synthesis conditions and changing particle size of the clay. The paint has unprecedented stability.

Abstract: Methods are described for the decontamination of soil containing heavy metals. In particular, these methods rely on phytoremediation using the plants of the species Larrea tridentata, the creosote bush. The methods are particularly directed at the decontamination of soil containing lead, copper, nickel and cadmium. The methods described herein are the first examples of phytoremediation using perennial plants which concentrate a high proportion of the scavenged metals in nonessential tissues, allowing the plants to be used continuously, rather than requiring repeated cycles of planting and harvesting entire plants in order to fully decontaminate the same area of land.
