    Abstract: According to embodiments, a method of forming a coating on an article includes forming a coating including an emitting layer. The emitting layer includes an elemental isotope with a known property that can be measured by a spectroscopic method. The elemental isotope provides a distinguishing identification tag for the coating, and the coating providing a layer of protection to the substrate. The method further includes depositing the coating on a surface of a substrate of the article. The elemental isotope is a stable isotope, an unstable isotope, a neutron scattering isotope, a neutron capturing isotope, or combinations thereof.

    Abstract: A radiation-shielding attenuation structure and method of forming the attenuation structure, wherein the attenuation structure is made by additively manufacturing a concrete material that includes one or more attenuation dopants configured to enhance the radiation shielding of the concrete material. The one or more attenuation dopants may be configured in the concrete material to attenuate one or more types of radiation, such as electromagnetic radiation, gamma radiation, X-ray radiation, or neutron radiation. The attenuation structure formed by the concrete material may be additively manufactured on-site according to a model that has already been pre-certified for safe or secure use, thereby providing a repeatable and reproducible process that can reduce lead times and fabrication costs. The attenuation structure may be easily modified during the additive manufacturing process to have different concrete mixtures with different attenuation characteristics, which increases the tailorability and flexibility in design of the attenuation structure.

    Abstract: A passive impact sensor for a projectile configured to explode, destroy with kinetic energy, embed or pass through an object with a closing velocity greater than 1,000 m/s. The passive impact sensor includes an energy generating system comprised of a crystalline structure that stores latent polarized electrical energy. The crystalline structure is responsive to an impact generated shock wave that propagates at least partially through the crystalline structure to consume and depolarize the crystalline structure and release at least a portion of the stored energy to generate a voltage pulse across output terminals. An onboard antenna is configured to transmit an RF pulse responsive to the voltage pulse (direct or integrated) external to the impact sensor (and projectile) before the sensor is destroyed by the shock wave. Multiple energy generating systems can be positioned either together or fore and aft and their voltage pulses summed to transmit the RF pulse. The benefits of this device include the ability to determine impact force, impact velocity, impact angle, target mass, target density, and direct or glancing impact.

    Abstract: A system and method for authenticating a physical object. The method may include the steps of: (1) encoding a feed material with randomized information; (2) forming the object with the feed material such that one or more portions of the object have respective randomized signatures based upon at least some of the randomized information of the feed material; (3) reading the respective randomized signatures at the one or portions of the object; (4) creating a profile of the respective randomized signatures at the one or more portions of the object based upon information from the reading; (5) transporting the physical object to an authenticator, and transmitting the profile to the authenticator; (6) reading the respective randomized signatures at the one or more portions of the object by the authenticator; and (7) comparing the reading by the authenticator to the profile received by the authenticator to thereby authenticate the physical object.
