High voltage electrical burns are uncommon. However in the midst of our economic recession we are noticing an increasing number of these injuries. Copper wire is a valuable commodity with physical properties as an excellent conductor of electricity making it both ubiquitous in society and prized on the black market. We present two consecutive cases referred to the National Burns Unit who sustained life threatening injuries from the alleged theft of high voltage copper wire and its omnipresence on an international scale.

Along with the rapid development of the digital economy and artificial intelligence, heat sinks available for immersion phase-change liquid cooling (IPCLC) of chips are facing huge challenges. Here, we design a high-performance IPCLC heat sink based on a copper microgroove/nanocone (MGNC) composite structure. Maximal heat fluxes () of the MGNC structure, microgroove structure, and flat copper reach 112.

This research explored the impact of age-hardening treatment on the mechanical response and electrical resistivity of copper-clad AA6063 alloy bimetallic wire, with a focus on microstructural analysis and interface characterization. In this study, AA6063 alloy wire was inserted into an oxygen-free high conductivity copper tube, and a bimetallic wire was fabricated through a wire drawing process that reduced the cross-sectional area in 13 stages. The bimetallic wire underwent a series of thermo-mechanical treatments, including various combinations of wire drawing, solution heat treatment, and artificial aging.

In the present study, our emphasis was directed towards the fabrication process of long multi-core superconducting wires, each spanning several hundred meters. These wires feature an in situ MgB core, an ex situ MgB barrier, and a copper shield. The cost-effectiveness of these constituent materials, coupled with a judicious arrangement of internal components, facilitates the utilization of an economical shielding material for the resulting wire.

Using a newly developed tool head with an additional rotational axis and a wire feed, wires can be directly processed in the fused filament fabrication (FFF) process. Thus, electrical structures such as conductive paths, coils, heating elements, or sensors can be integrated into polymer parts. However, the accuracy of the wire deposition in curved sections of the print track is insufficient.
