A Mechanistic Analysis of Oxygen Vacancy Driven Conductive Filament Formation in Resistive Random Access Memory Metal/NiO/Metal Structures

Resistive Random Access Memory (RRAM) devices have drawn much interest in the last decade, particularly the concept of a memristor. In this case, the so-called memristance, which provides the relationship between the change in charge (time integral of the current) and flux (time integral of the voltage), is not a constant as in linear elements, but a function of the charge, resulting in a nonlinear circuit element. Applications of such two-terminal electrical devices that provide high densities and low-power operation include, for instance, neuromorphic-type computing elements.

Quality Control for Additive Manufacturing Parts Using Non-Destructive Testing

Additive Manufacturing (AM) is growing in importance as a fabrication process for the space industry, enabling weight and cost savings through optimized designs for components. The use of AM gives aerospace engineers an alternative to more traditional manufacturing processes, but also retains the challenge of producing parts without defects. These problems can be approached using nondestructive methods such as X-ray Computed Tomography (CT) and Finite Element Modelling (FEM) to inspect geometries and quantify the impact of defects on the mechanical properties of a part, taking into account factors such as internal stress from metal cooling during fabrication.

Army 3-D Prints a Building

The Construction Engineering Research Laboratory in Champaign, Illinois, has successfully three-dimensionally printed a 512 square-foot concrete structure. The structure, called a barracks hut or B-Hut, was printed as a result of a three-year Army Program called the "Automated Construction of Expeditionary Structures." It uses an additive manufacturing process to "print" semi-permanent structures in a theater of operation. The ability to use concrete sourced from readily available materials reduces logistical requirements for the U.S. Army.
