Dielectric: materials commonly used as insulators in spark gaps (Lexan, Nylon, Lucite, Macor, Boron Nitride, Delrin and G-10) have been exposed to the by-products of arcs in three different spark gap experiments. The first was a 60 kV, 0.05 Caul/shot spark gap using copper-tungsten or graphite electrodes at various pressures of N2 or SF6 gas. The second was a 5-30 kV, 4-25 kA, .l-.6 Coul/shot, ...

Exfoliated graphite electrodes have been used to detect uric acid at neutral pHs, by following its oxidation. A linear range of 5 ± 53 M and a detection limit of 5 M are observed at a pH of 7.0. Uric acid was found to be selectively adsorbed on exfoliated graphite surface in the presence of excess ascorbic acid. This leads to its selective determination in the presence of ascorbic acid. Simulta...

Microbial fuel cell represents an emerging technology to attain electrical energy from wastewater. There are several alternative methods available for wastewater treatment; Microbial fuel cell is one of them, which generates green energy from wastewater for making a contribution to renewable sources of energy. This study states the performance of microbial fuel cell with different parameters i....

We demonstrate for the first time concept of ion sensing pencil (ISP). The pencil’s lead carries chemical functionality and is constructed by compression graphite zeolite, while clutch prepared 3D printing. ISP can be used to draw a sensor simple abrasion onto hydrophobic surface. stored at home, immediately off-the-shelf without any handling prior measurements. It’s preparation, handling, meas...

This paper presents an alternative strategy for manufacturing solid-state reference electrodes based on particles of graphite/silver/silver chloride synthesized by electroless deposition of metallic silver and silver chloride on graphite powder. Two kinds of reference electrodes were manufactured by mixing these particles with epoxy resin and hardener: quasi-reference and all-solid-state contai...

Generation of subpicosecond terahertz pulses is observed when graphite surfaces are illuminated with femtosecond near-infrared laser pulses. The nonlinear optical generation of THz pulses from graphite is unexpected since, in principle, the material possesses a centre of inversion symmetry. Experiments with highly oriented pyrolytic graphite crystals suggest that the THz radiation is generated ...

The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...
