Investigation of Copper Wire-Mediated Controlled/Living Radical Polymerization
Copper wire mediated controlled living radical polymerization (CLRP) is a powerful tool that provides numerous opportunities for the development of new materials. It requires low catalyst loading and mild reaction conditions, but does involve use of organic solvents. There is a need for greener …

Smoothed Particle Hydrodynamic Modeling of Solid State Additively Manufactured Aluminum Alloys
… the outside of the feedstock, and one using a copper wire core feedstock to track copper distribution in the deposition, which is analogous to material flow from the inside of the feedstock. Results revealed the tendency of oxides to flow to the retreating side. The copper wire was mainly …

An investigation of the effects of cold working upon copper
… to stress to strain follows a different law. Copper and steel are both ductile materials, and it is, therefore, logical to assume that they will show similarity of characteristics. Copper and steel have individual peculiarities, but copper appears to be erratic in its behavior. For example, …

Electron Generations and Transportation in Fast Ignition Experiments
… had a 40 μm diameter, approximately 1mm long copper wire attached to its tip. An electron spectrometer was used which was aligned along the axis of the wire attached to the gold cone. Results of the experiment explained the electron energy spectrum in a high energy picosecond 1.053 μm laser …

Interactions Between Copper and Chlorine Disinfectants: Chlorine Decay, Chloramine Decay and Copper Pitting
Interactions between copper and chlorine disinfectants were examined from the perspective of disinfectant decay and copper pitting corrosion. Sparingly soluble cupric hydroxide catalyzed the rapid decay of free chlorine, which in turn, led to production of less soluble and more crystalline phases …

An analysis of influential methodological practices in consumption-based accounting methods
… to a case study assessing the carbon burden of copper wire. An industry-leading process-based model was analysed using gap analysis and system boundary selection, and identification methods assessed. Key methodological factors were found to be the inclusion of multi-regional data and sensitivity …

An industry-leading process-based model was analysed using gap analysis and system boundary selection, and identification methods assessed. Key methodological factors were found to be the inclusion of multi-regional data and sensitivity …

Single Degree of Freedom Solid Rotor Velocity Control Induction Drive
… radially inward, wound with 160 turns of copper wire each in a three-phase, two-pole configuration. A steel enclosure houses the stator and is supported by a 3D-printed polylactic acid (PLA) enclosure. The wiring is initially connected in wye configuration without a neutral wire but later …

Earth electrode resistance diagnosis and measurements
… thesis investigates the potential of an aluminum wire coated with semiconducting plastic material (AX-PRO) as a viable alternative to copper wire for use in grounding systems, particularly under Icelandic conditions. Copper has traditionally been the preferred material for grounding due to its …

A finite element approach for the implementation of magnetostrictive material terfenol-D in automotive CNG fuel injection actuation
… properties as the injector housing material, AWG copper wire as the coil material and 316 Stainless Steel having non-magnetic properties as the plunger material. A 2D cross-sectional geometry including the injector housing, coil, Terfenol-D shaft, and plunger, was modeled in both Finite Element …

Six-Axis Levitated Stage with a Novel Flux-Steering Magnetic Hub Actuator
… inward, each with a coil of 454 turns of AWG 20 copper wire. The teeth each have a nominal air gap of 0.5 mm with the mover, though only half of the air gap is used for motion (250 µm radius circle of travel). To increase the force density, permanent magnets are arranged to create north poles on …

Analysis of the nail board experiment to measure the liquid slag depth in steel continuous casting
… in the continuous casting of steel. Aluminum wires are often added to measure the liquid slag layer depth as well. This work investigates the accuracy of the nail board test used for measurement of the liquid slag layer depth. In addition, a new methodology for measuring the liquid slag layer …

Characterization of mechanical properties of copper covetic wires
Copper and copper alloys are commonly used in various applications because of their ability to be formed and their excellent thermal and electrical properties. A new copper carbon alloy, called copper covetic, is showing promising properties. Copper covetic materials were prepared Third Millennium …
