Abstract: This invention uses large surface to volume ratio materials for separation, release layer, and sacrificial material applications. The invention outlines the material concept, application designs, and fabrication methodologies. The invention is demonstrated using deposited column/void network materials as examples of large surface to volume ratio materials.
