Natural dyes for solar cell application: uv-visible spectra and outdoor photovoltaic performance
(Research Journal in Engineering and Applied Sciences, 2014-09)
Successful conversion of visible light into electrical output was achieved by using four locally available natural dyes as
wide band gap semiconductor sensitizers in Dye-sensitized solar cells. Natural dyes extracted from ...
An Analysis of Fuel Properties of Fatty Acid Methyl Ester from Manketti Seeds Oil
(Taylor & Francis Online, 2014-11-20)
The fatty acid methyl esters (FAME)produced from vegetable oils, animal fats, or waste oils known as biodiesel has attracted attention as possible replacement of fossil fuels. The fuel properties of biodiesel are similar ...
Mungongo Seeds Oil (Schinziophyton rautanenii) as a Potential Source of Bio-Diesel
(Scientific.Net, 2014-01)
Biodiesel from mungongo seeds oil (Schinziophyton rautanenii) was investigated in the present study to determine its suitability for use as substitute of petro diesel. The fuel properties of Mungongo Oil Methyl ester (MOME) ...
A review on opportunities for the development of heat pump drying systems in South Africa
(South African Journal of Science, 2014-05-28)
Recently, it has been discovered that heat pump drying is an efficient method of drying for drying industries. Heat pumps deliver more heat during the drying process than the work input to the compressor. Heat pump drying ...

The properties of feldspathic dental porcelain from Tanzanian aluminosilicate materials
(International Journal of Development Research, 2014-11-18)
Kaolin and quartz from Pugu and feldspar from Morogoro were used to produce feldspathic dental porcelain bodies. Mineralogical results from XRD revealed the presence of kaolinite, illite, microcline and clinochlore in the ...
Geometrical Structure, Vibrational Spectra and Thermodynamic Properties of Chitosan Constituents by DFT Method
(Science Publishing Group, 2014-08-10)
The interaction between glucosamine molecules has been studied theoretically. The geometrical structures of monomer (A), dimer (AA) and trimer (AAA) molecules of glucosamine were optimized and vibrational spectra were ...
Development of a cost-benefit analysis approach for water reuse in irrigation
(Science Publishing Group, 2014-10-10)
Water reuse is one of the alternatives to counteract the already experienced water shortages. However water
reuse as any other investment is associated with costs. This article looks at water reuse for irrigation as one ...
