    Abstract: The intensification of agricultural, domestic and industrial activities leads to the increasing contamination of groundwater and surface water by nitrates. Indeed, agricultural runoff, septic tank effluents, landfill leachates or wastewater treatment plant effluents contribute to this nitrification, yet drinking water containing high nitrate conten...

    Abstract: The quantum Rice-Ramsperger-Kassel (QRRK) theory is used to analyze the reaction between the activated CH3S CH•CH3 and molecular oxygen to account for further reaction and collisional and deactivation. hydroxyl radicals initiate the oxidation of Methyl ethyl sulfide (CH3SCH2CH3) and MES (methylthioethane) under combustion conditions. The CBS-QB3 an... Show More

    Abstract: Organometallic sandwich complexes exhibit a number of potential structural and electronic properties and attract the attention of many researchers in recent years. In this paper, we systematically studied the structure and stability of Ln(C8H8) and Ln(C8H8)2 (Ln = Ce, Eu, Ho, Nd and Yb) complexes using density functional theory calculations. It i... Show More

    Abstract: The aim of the present paper is to check - or better to confirm - the mathematical validity of chemical reaction rate, faced as a set of differential equations. Firstly one - way elementary reactions are considered, in the most general case. Secondly the same thing is done with two-way (opposing) elementary reactions. At this stage, we show that th...

    Abstract: To better understand some of the local metallurgical mechanisms, it is necessary to have information about the scale of the stress gradient in the vicinity of a grain boundary or around a precipitate. This measurement is accessible by Kossel microdiffraction. Diffraction consists of the emission of Kossel cones, which are then intercepted by a scre... Show More
