Abstract: In some examples, a controllable read blocking based radio-frequency identification (RFID) device may include a substrate layer, and a trace formed of a conductive material and disposed on, partially within, or fully within the substrate layer. The controllable read blocking based RFID device may further include a controllable read blocking layer disposed on the substrate layer and the trace and including a fluid disposed in the controllable read blocking layer to selectively block or allow passage of electromagnetic waves to the trace to respectively inhibit or allow communication of a RFID reading device with the controllable read blocking based RFID device.

Abstract: Examples associated with three-dimensional model generation are disclosed. One example includes analyzing a structure of a first component of an object. The composition of the first component of the object is also analyzed. A three-dimensional model of the object is then generated. The three-dimensional model includes data based on the structure of the first component of the object and data based on the composition of the first component of the object.

Abstract: A method of determining the geographic origin of a metal can comprise measuring a first isotope and a second isotope of the metal by high-resolution mass spectrometry; calculating a ratio of the first isotope and the second isotope; comparing the ratio to native ratios of isotopes of the metal of native samples from a plurality of geographic locations using a database; and matching the ratio to a geographic location.
