Abstract: A primary alloy includes: nickel; copper; zinc; an electrical conductivity from 5.2% International Annealed Copper Standard (IACS) to 5.6% IACS measured in accordance with ASTM E1004-09 (2009); and a disordered crystalline phase wherein atoms of the nickel, cooper, and zinc are randomly arranged in the disordered crystalline phase at room temperature in a post-annealed state. A process for making the primary alloy includes heating a secondary alloy to a first temperature that is greater than or equal to an annealing temperature to form an annealing alloy, the secondary alloy including a secondary phase; and quenching, by cooling the annealing alloy from the first temperature to a second temperature that is less than the annealing temperature, under a condition effective to form the primary alloy including the disordered crystalline phase, wherein the disordered crystalline phase is different than the secondary phase of the secondary alloy.

Abstract: Systems and methods for controlling the temperature of small volumes such as yoctoliter volumes, are described. The systems include one or more plasmonic nanostructures attached at or near a nanopore. Upon excitation of the plasmonic nanostructures, such as for example by exposure to laser light, the nanoparticles are rapidly heated thereby causing a change in the ionic conductance along the nanopore. The temperature change is determined from the ionic conductance. These temperature changes can be used to control rapid thermodynamic changes in molecular analytes as they interact with the nanopore.

Abstract: A contactless, three-dimensional fingerprint scanner apparatus, method, and system are described. The contactless fingerprint scanner can provide either, or both, topographical contrast of three-dimensional fingerprint features and optical contrast of a three-dimensional fingerprint surface. Data captured from scanning of a target with known geometric features mimicking fingerprint features can be examined as images or surface plots and analyzed for fidelity against the known target feature specifications to evaluate or validate device capture performance as well as interoperability. The target can be used by scanner vendors and designers to validate their devices, as well as to perform type certification.
