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...

The determination of the water chemistry for cooling systems nuclear fusion plants is under debate. It should be tailored different types reactors: either experimental, e.g., ITER, JT-60SA, and DTT, or aimed at power generation, DEMO, given operation requirements. This paper presents dual approach involving experiments computer simulations chosen definition DEMO chemistry. Experimental work was...

The need for predicting pipeline service life and improving risk assessment relating to corrosion hazards requires establishing a correlation between the rate (CR) of steel its coating condition, cathodic protection (CP) levels surrounding soil conditions. This paper presents systematic study CR bare coated—with without dent or holiday defect—X60 in simulated field environments. Three CP scenar...
