Paper Abstract

Particles are frequently used to impart security features to high value items. These particles are typically produced by traditional methods, and therefore the security must be derived from the chemical composition of the particles rather than the particle production process. Here, we present new and difficult-to-reproduce particle production processes based on spray pyrolysis that can produce unique particles and features that are dependent on the use of these new-to-the-world processes and process trade secrets. Specifically two examples of functional materials are described, luminescent materials and electrocatalytic materials.
