    Abstract: Carbon dioxide (CO2) is an important heat-trapping gas, which leads to a rise in the earth's temperature causing climate changes with adverse effects. This climate change created the need for national and international programs to monitor the levels of carbon dioxide emissions into the atmosphere. The CO2 monitoring programs should be supported wit... Show More

    Abstract: The structure and binding mode of N-Salicylidene alanine Ni (II) Schiff-base complex has been analyzed using experimental and computational techniques. The synthesis, characterization and computational studies of the Schiff-base complex revealed a more stable square planar geometry (structure 4a). Characterization of the complex was done using melt... Show More

    Abstract: Biogas is one of the most attractive renewable resources because of its ability to convert waste into energy. Biogas is produced during an anaerobic digestion process from various organic waste resources. It is composed of mainly CH4, CO2, and some trace gases such as hydrogen sulphide (H2S) which is a very toxic, deadly and corrosive gas. Therefor... Show More
