This paper presents a novel derivative of flash sintering, in which contactless flash sintering (CFS) is achieved using plasma electrodes. In this setup, electrical contact with the sample to be sintered is made by two arc plasma electrodes, one on either side, allowing current to pass through the sample. This opens up the possibility of continuous throughput flash sintering. Preheating, a usua...

many studies employing various methods have been carried out into the number densities of excited atoms in electrical discharges with inert gases [1,2,3], but the ranges of the discharge current and gas pressure is very limited in them all. in this work, the population densities of 3s, 3s' of neon have been investigated using the atomic absorption method. since the discharge current and ga...

Then came the discovery of carbon nanotubes (CNTs) by Iijima [2] of NEC Laboratories, Japan, who observed these ‘needle like tubes’, which are 50,000 times thinner than human hair. He proposed a new growth model and produced these structures using an arc-discharge evaporation method. During the same year (1991), a Japanese company developed a method to grow carbon nanofibers (CNFs) [3]. Ever si...

Carbonaceous materials have recently received attention in electronic applications and measurement systems. In this work, we demonstrate the electrical behavior of carbon films fabricated by methane arc discharge decomposition technique. The current-voltage (I-V) characteristics of carbon films are investigated in the presence and absence of gas. The experiment reveals that the current passing ...

This paper deals with the development of a model for concrete subjected to dynamic loads. Shock waves are generated by Pulsed Arc Electro-hydraulic Discharges (PAED) in water and applied to mortar samples. A diphasic model (liquid water and vapour) is implemented in order to describe the electrical discharge and the propagation of shock waves in water. An anisotropic damage model is devised, wh...

We demonstrated a compact and highly-sensitive curvature sensor based on a Mach-Zehnder interferometer created in a photonic crystal fiber. Such a Mach-Zehnder interferometer consisted of a peanut-like section and an abrupt taper achieved by use of an optimized electrical arc discharge technique, where only one dominating cladding mode was excited and interfered with the fundamental mode. The u...

In low voltage distribution networks, there is a high risk of fires caused by wiring faults that lead to short circuits. Arcing protection devices (ARCs) already exist, but experiments show they also often do not disable such faults. The operation most existing arc fault detection based on the frequency current components and their comparison with load profiles. For fast recognition low-frequen...
