22. Enhancement of Photoconversion Efficiency of P3HT:PCBM Polymer Solar Cell Using Squarylium iii Dye
Ternary systems comprising of poly(3-hexylthiophene)(P3HT):(6,6)-phenyl-C61 butyric acid methyl ester (PCBM) and varying amounts of squarylium dye III (SQ3) were prepared and deposited by spin coating to obtain nano-size thin films. The films produced were subsequently annealed at 140 C for 10...
Download PDF ↓Planet Earth is approximately spherical in shape, and is three dimensional. To map the Earth on a flat piece of paper, in two dimensions, a map projection must be carried out. A map projection is a mathematical technique of how to represent the Earth’s curved surface on a flat surface. In Zambia,...
There has been a lot of outcry from the public that Zambia’s mineral tax reforms, with an aim to optimize revenue benefits from the mines, have not yielded the desired results. This has mainly been attributed to the weak design of its legislated mineral taxation systems. Due to this underlying...
Post-harvest Losses (PHLs) in fruits are high, in some cases, reaches 50 %. To reduce these PHLs, several technologies have been developed; among them is solar drying technology (SDT). Several SDTs are available including solar tunnel dryers. Solar tunnel dryers are described as relatively...
Download PDF ↓The focus of the study was to establish factors which influence sustainability of boreholes managed by communities in Chadiza District. In order to do that, the study intended to answer three research questions which are: (i) How does community participation at the initial stage of the borehole...
Download PDF ↓The aim of this study was to carry out an experimental investigation on drying fresh Kapenta (Stolothrissa tanganicae), in a Greenhouse Solar Dryer and to evaluate a suitable thin-layer drying model for fresh Kapenta. The nutritional constituents and quality of dried Kapenta produced from a...
Download PDF ↓The objective of the research was to optimize memory usage in body sensor network (BSN) nodes during key agreement generation. In BSNs, it is important to secure communication between BSN nodes to ensure confidentiality, authenticity, and integrity of the information. The BSN node is faced with...

The behaviour of sodium hydroxide treated sisal fibre-reinforced polyester composite subjected to environmental ageing conditions has been studied with the aim of modelling its effect on the composite fracture damage for the purpose of long-term performance prediction. The composite was...
Download PDF ↓Molecularly imprinted polymers are a class of new functional materials that bring about selectivity to chemical sensors that is similar to that found in biological systems. The technique enables the creation of artificial recognition cavities within synthetic polymers that can be used in chemical...
