    Abstract: Marine sediments samples from Bargny coast (Senegal) were analyzed by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The microwave acid digestion was also employed for metals (Cd, Pb, Cr, As) determination. The physicochemical parameters (pH, temperature, salinity, electrical conductivity) measured complied with European water standards. Fi... Show More

    Abstract: Metal corrosion phenomenon is an important topic in many industries because of its consequences on industrial equipment. The purpose of this study was to investigate the inhibition potential of three vitamins on aluminum corrosion in 1M HCl using experimental and theoretical techniques. So, the inhibitive effect of three vitamins that are vitamin B... Show More

    Abstract: An equilibrium phase study is very important for the design, optimization, and control of transformation and separation operations. The investigation of liquid-liquid or liquid-vapor equilibrium has been the subject of much interest in the chemical and petrochemical industry in recent years. Optimizing separation processes is one of the most import... Show More

    Abstract: Steam Methane Reforming (SMR) is by far one of the key industrial processes that can help in achieving green and sustainable energy. As a major source of hydrogen (the so called future and green fuel), valuable oxygenated chemicals and key reaction for solid oxide fuel cells, the process solely depends on the presence of a metal supported catalyst ...

    Abstract: The recovery and recycling of all used tires is a constant challenge in a century where respect for the environment is becoming increasingly important and a key success factor. The Environmental Protection Agency (EPA) has classified citric acid as “Generally Recognized as Safe – GRAS”, in consequence its use as raw material is beneficial for all a... Show More

    Abstract: This reactivity and stability work was performed on six (6) Thiazoline derivatives using density functional theory at the B3LYP/6-31+ G (d, p) level. The aim was to determine the electrophilic and nucleophilic sites and the chemical behaviour of thiazolines. To do this, we calculated the fukui reactivity parameters (f+; f-), as well as the conceptu... Show More

    Abstract: The search for higher and higher agricultural yields leads to the use of chemical fertilizers and phytosanitary products. The abusive or repeated use of these agricultural inputs results in soil, surface water and groundwater pollution. With the development of this new form of agriculture, the input of heavy metals to the soil has increased. Resear... Show More
