Carbon thin films were deposited on Silicon (Si) substrates by electrolysis of methanol. The effect of camphor (C<inf>10</inf>H<inf>16</inf>O) &#x2014; a natural source, incorporation in methanol is investigated. Camphor with varying amount (2%, 4%, 6% and 8%) was mixed in methanol solvent to prepare the electrolytes. Silicon substrates were mounted on the(More)
Carbon thin films were deposited on Aluminium(Al), Copper(Cu) and Silicon(Si) substrates by electrolysis of methanol. The effect of camphor (C<inf>10</inf>H<inf>16</inf>O) a natural source, incorporation with methanol is investigated. Camphor with varying amount was mixed in methanol solvent to prepare the electrolytes. Al, Cu and Si substrates were mounted(More)
In this study, adsorption characteristics of arsenic on commercially produced multiwall carbon nanotube (MWCNT) have been assessed in laboratory experiments. Batch adsorption tests were carried out under different conditions (e.g. varying dispersion time, varying amount of materials) in order to evaluate the suitability of Multiwall Carbon nanotube(More)
This paper examines the performance of Ĉuk regulator to convert three phase alternating current (ac) to direct current (dc). Firstly, three phase ac is rectified with bridge diode. The rectified dc voltage is applied to input of a Ĉuk regulator. Three phase harmonics filter is introduced at the input of the diode rectifier to improve the shape of the input(More)
