NaturalNano President Michael Riedlinger Unveils Proprietary Applications for Halloysite Nanotubes at Stephens Inc 2005 Nanotechnology Investors Conference



April 14, 2005 -- New proprietary commercial applications of "halloysite nanotubes" were presented today by NaturalNano Inc. President Michael Riedlinger at the 2005 Stephens Inc. Nanotechnology Investors Conference in Pasadena.

He also presented dramatic new electron-microscope images showing halloysite nanotubes as they exist in naturally formed clay. "Historically, halloysite clay has been used for production of fine china tableware, but not until there was a close examination of the material were the halloysite nanotubes discovered in it," said Mr. Riedlinger.

Halloysite nanotubes are ultra-tiny tubes consisting of silicon, aluminum, hydrogen, and oxygen. They typically measure under 100 nanometers (billionths of a meter) in diameter and are extracted from naturally formed clay. NaturalNano has purchased 500 tons of this clay from Atlas Mining Company (OTC BB: ALMI, www.atlasmining.com) for processing.

Halloysite nanotubes offer a broad array of industry applications, he explained. "For example, they can be used for radio-frequency shielding using a patent-pending, proprietary metallization coating process. Our scientists have also developed proprietary technologies for extracting and separating the nanotubes from clay and classifying them in different diameters and lengths. That now allows these nanotubes to be used for a wide range of applications, such as cosmetics, electronics and microcircuitry, and additives for paints, polymers, plastics and composites. We have identified more than 100 applications of halloysite nanotubes in our patent applications filed to date and our scientists are working on a large number of additional applications."

A webcast of Mr. Riedlinger's slide presentation and talk today is available at www.naturalnano.com/stephens.htm until May 6, 2005.

The two-day conference brought together leading nanotechnology companies and a range of guest speakers with a mix of scientific, investment, and industry experience. Delivering the keynote address was Dr. Michael L. Roukes, Founding Director of the Kavli Nanoscience Institute at the California Institute of Technology (Caltech).
