Titanium alloys are widely used as construction materials in the aerospace and automotive industries. They have many advantages but also limitations related to their susceptibility high-temperature oxidation hot corrosion. Many efforts increase lifetime of components made titanium been reported literature; most promising ones involve deposition coatings. The present paper is focused on developm...
Soil salinization is more aggravating than ever before and techniques are needed to mitigate this problem; understanding salinity-fertilizer relationship of considerable economic importance for promoting crop growth productivity in saline soil. A pot experiment was done a greenhouse determine whether the N could alleviate negative effect different salts compositions on growth, physiological att...
The high internal resistance (Rint) that develops across the sediment microbial fuel cells (SMFC) limits their power production (~4/10 mW mâ2) can be recovered from an initial oil-contaminated (OCS). In anolyte, Rint is related to poor biodegradation activity, quality and quantity of contaminant content in anode material. While on catholyte, depends properties oxygen reduction reaction (ORR),...
Neonicotinoids pesticides were introduced to the market in 1990s control various pests. Its accumulation environment supposes a severe problem that can affect human health. This study investigates electrochemical degradation of four common neonicotinoid pesticides; thiamethoxam (TMX), imidacloprid (ICP), acetamiprid (ACP) and thiacloprid (TCP), different natural surface waters by boron-doped di...
A series of composite materials of general molecular formula (1 - x) Na2SO4 - (x) LDT was prepared by solid state reaction method. The phase structure and functionalization of these materials were defined by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) respectively. Differential thermal analysis (DTA) revealed that the hump of phase transition at 250 °C has decrea...
