The presence of H2S ( hydrogen sulphide ) gas in oil and gas exploration can give rise to critical safety problems because of its corrosivity and toxicity. In order to protect people and equipment, there is a need for a real-time,remote and reliable seneor that can detcet the concentration of H2S gas. The best way to monitor H2S gas concentration is optical-electrochemical sensor technology. At...

Dwr Cymru Welsh Water supplies over three million people with drinking water throughout most of Wales (UK). Ortho-phosphate has increasingly been dosed at around 1 mg/L (P) to further reduce the corrosivity of supplies to the lead pipes which connect approximately 30% of houses to water mains in the company's area, additional to long-establish pH adjustment measures. The installation of new ort...

Abstract Concentrated solar thermal technologies play an essential role in the energetic transition which is currently facing our society. The energy generation this technology vastly depends on optical behaviour of reflector materials field. Corrosion reflectors might be issue locations with high corrosive environments because excessive corrosion mirror could catastrophic for profitability con...

Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...

Abstract Biodiesel is a clean fuel, and an alternative to the environmental complications ascribed fossil fuels. However, forms of its production are still object research in literature because some issues related process improvement economical viability remain challenge. Consequently, this aims produce biodiesel by ethylic route from Ricinus communis L. oil extracted with simple solid liquid e...
