Abstract: A few mixed ligand complexes of the general formula [M (mordtc)(1,10-phen)] where M=Ni(II),Co(II),Cu(II), Zn(II)have been synthesised and characterized by electronic and infrared spectroscopy, and elemental analysis. The metal complexes were screened against gram positive bacteria (Streptococcus pneumonia and Staphylococcus aureus) and gram negative bacteria (Klebsiella subtilis and Escherichia coli) using Agar diffusion test. The complexes recorded a moderate activity against the screened pathogens.

Abstract: Chemical kinetics is a branch of physical chemistry which is concerned with the study of the rates of chemical reactions and with the elucidation of the mechanism by which they proceed. Activation energy is an important parameter in kinetics whose knowledge assists one in determining the optimum energy requirement for the target reaction. The rate of the reaction was measured by monitoring the rate of disappearance of Toluene from the reaction mixture at various time intervals using UV/Vis spectrophotometer at 259nm (λ max). The experiment was carried out at 30ºC and then repeated at 35ºC, 40ºC, 45ºC and 50ºC. From the various absorbance generated at these temperatures, the values............

Abstract: In Nigeria, various environmental laws have been enacted from pre-independence to date as a direct response to tackling environmental degradation in the country. This degradation in the environment has led to unpleasant challenges to economic development of Nigeria and the well-being of its citizenry. Some of these environmental problems /challenges include, but are not limited to, deforestation, desertification, oil spillage, pollution, global warming. The National Environmental Standard and Regulations Enforcement Agency (NESREA) Act 2007is one of the most recent and effective laws passed by the government of Nigeria to tackle environmental challenges and create awareness on environmental protection. This paper analyzes the role of the NESREA Act 2007 in ensuring Environmental............

Abstract: Environmental Impact Assessment (EIA) has evolved and become part of major project requirement in many countries including Nigeria for the attainment of sustainable development and reduction of poverty levels of people affected by projects. EIA is a useful tool for promoting sustainable development because it contains many components that can facilitate equality in every aspect and it can minimize environmental degradation by identifying problems before they occur. Environmental Impact Assessment (EIA) needs to show that it can contribute to poverty alleviation, employment generation, environmental protection and improved economic development effectively towards sustainable development. This paper examines EIA in Nigeria, how it can be used effectively and efficiently for developmental projects and its shortcomings while implementing during implementation

Abstract: A simple one-pot hydrothermal synthesis strategy has been approached to prepare the composite viz.reduced graphene oxide-ZnO nanoparticles (~30 nm)(RGO–ZnO).The synthesized RGO–ZnO composite has been successfully applied for glassy carbon electrode (GCE) surface modification. The RGO–ZnO composite-modified GCE is applied for sensitive and selective determination of Methyl Parathion(MP).The as-prepared composite is characterized by using Fourier Transform Infra-Red Spectroscopy(FT-IR),Scanning Electron Microscopy (SEM) along with Energy Dispersive X-ray (EDX) and elemental mapping. The atomic force microscopy (AFM) and Transmission electron microscope (TEM) with SAED analysis confirm the presence of ZnO nanoparticles embedded over the entire surface of reduced graphene oxide..........

Abstract: Acetylene is considered as an undesired component in polymerization reactors, which can afford unwanted properties in the final products and harmful effects on the related catalyst. The most efficient method to eliminate Acetylene and to decrease its purity to 2-3 part per million is the selective hydrogenation process. Even though widespread experimental efforts have been implemented on different aspects of acetylene hydrogenation reactors in many articles, they mostly represent a modelling which may be accurate for that
special case study, and different parameters variations which are effective in the modelling, have not been investigated based on valid industrial process criteria as sensitivity analysis and optimization cases. In this article, Acetylene hydrogenation reactor modelling..........
