Phase Analysis of Series Arc Signals for Low-Voltage Electrical Devices

Energies, 2020
An arc fault is an electrical breakdown of the insulating medium in an electrical system. When arc faults occur, they cause electrical fires with local sparks and temperatures of over 5000 °C.

Harnessing the mechanism of glutathione reductase for synthesis of active site bound metallic nanoparticles and electrical connection to electrodes.

Journal of the American Chemical Society, 2008
It is demonstrated herein that the FAD-dependent enzyme glutathione reductase (GR) catalyzes the NADPH-dependent reduction of AuCl4-, forming gold nanoparticles at the active site that are tightly bound through the catalytic cysteines.

Multidimensional Electrical Networks and their Application to Exponential Speedups for Graph Problems [PDF]

Quantum
Recently, Apers and Piddock [TQC '23] strengthened the connection between quantum walks and electrical networks via Kirchhoff's Law and Ohm's Law. In this work, we develop a new multidimensional electrical network by defining Alternative Kirchhoff's Law ...

Glowing Electrical Connections

Journal of the National Academy of Forensic Engineers, 1992
The writer discusses an electrical phenomenon which can cause fires and is reported in the literature. Nevertheless it tends to be overlooked by investigators because it is more subtle than other phenomenon, may take a long time to develop into a working fire, and is not as well documented as other electrical ignition phenomenon. This article discusses

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging
