Abstract: Increase in global population places a demand on fuel and protein sources therefore putting a strain on their supply. The demand for fuel products is currently met by increased usage of fossil fuel, a nonrenewable energy source. However, burning of fossil fuel has challenges such as the release of greenhouse gases associated with negative environmental impacts. To overcome these challenges, attention has been given to renewable energy sources as biodiesel, a biofuel that has...
ABSTRACT: Most of the available water sources such as streams, rivers and wells have been impaired by anthropogenic activities thereby rendering them unsafe for consumption. This has made access to clean potable water a mirage to communities situated in the semi urban areas, hence, increasing their daily risk of contracting water borne diseases. This work initiates the treatment of these water sources with dried duckweed plant. The duckweed plant was prepared and incorporated into a ceramic w...
An investigation was carried out to identify the different types of polymers used in paint and surface coatings and variations of the final products upon modifications of the materials used. The process of manufacturing paint and surface coatings involves a great deal of understanding various molecular behavior of paint and surface coatings polymeric matrix. These advance knowledge helps in developing new and advanced modifications of the super polymers. Every desire of a paint and surface co...
Abstract Elemental bismuth has been reported to exhibit antimicrobial activity, but it does so only at relatively high millimolar concentrations due to its limited solubility in water. However, its solubility can be increased upon chelation with other materials like curcumin thereby increasing its potential as antimicrobial agent even at much more lower concentration. In this study, a novel Bismuth nanoparticless were prepared from non-toxic curcumin as stabilizing and capping agent to elim...
Reverse Osmosis (RO) is the finest of all membrane filtration system, it is a membrane based technology to purify water by separating the dissolved solids from feed stream resulting in permeate and reject stream for a wide range of applications in domestic as well as industrial applications. The objective of this paper is to review the concept of reverse osmosis and the current developments in the RO membrane materials which are the key determinants in the process. This review paper also ...
Phytochemical investigation was carried out on the crude ethanol extracts of the leaves of Spondias mombin. The antibacterial activity of the ethanolic and the Chloroform leaf extract was tested against four bacteria; Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi using disc diffusion method. The results indicated that both extracts showed inhibitory activity against clinical isolates of the gram negative bacteria Staphylococcus aureus, P. aerugi...
ABSTRACTS Some compounds have been proposed as analytical reagents for the spectrophotometric determination of chromium, tin and lead ions. The application of these reagents for the determination of these metal ions is listed and several procedures are described to illustrate the fundamental conditions for the spectrophotometric determination of these metal ions. Key words: Analytical reagents, chromium, tin, lead, spectrophotometric determination, extraction, complexes. 1.0 INTRODUCTION Ch...
