Water quality variation and pollutants transformation in the Nadosoito dam of Arkatani village, Monduli district
(NM-AIST, 2019-02)
The study aimed at assessing seasonal dynamics of water quality parameters, transformation of selected pollutants and seasonal diversity of selected microorganisms (Cyanobacteria) in Nadosoito dam of Arkatani Village, ...
Theoretical and experimental studies of combination of synthetic dye (indoline d131) and natural dye (lawsone) for dye sensitized solar cells applications
(NM-AIST, 2019-02)
Dye sensitized solar cells (DSSCs) convert visible sunlight to electricity using a wide band semiconductor. The DSSCs have attracted many researchers due to their environmental friendliness, low manufacturing cost and ...
Risks of sanitation facilities to groundwater pollution in Babati town, Tanzania
(NM-AIST, 2019-03)
Despite of its importance for human consumption groundwater resource is under threat of
overexploitation and pollutions. The study to assess the risks of sanitation facilities to
groundwater pollution was carried out in ...
Investigation of combination effect of natural dye (crocetin) and synthetic dye (indoline d205) for dye sensitized solar cells application
(NM-AIST, 2019-02)
Dye-sensitized solar cells (DSSCs) are reckoned as emerging next-generation solar cells of a high potency. Co-sensitization of dyes facilitates widening of the light absorption range of a sensitizer and is one of possible ...
Removal of hydrogen sulfide and ammonia from biogas using Oldoinyo Lengai Volcanic ash
(NM-AIST, 2019-02)
Oldoinyo Lengai mountain located in Northern Tanzania is the only active natrocarbonatite volcano with unusually alkali-rich natrocarbonatites which are not found elsewhere in the world. Volcanic ash formed earlier during ...
Optimization of biogas production process in solid state digesters: option for minimizing deforestation in dry areas
(NM-AIST, 2019-03)
Questionnaire survey, satellite images of 1987, 1997, 2002 and 2017 were used to assess energy sources, demand and the impact of fuel wood use to forest cover changes in Meru and Mwanga districts. The major energy sources ...
Evaluation of dielectric and mechanical strength of high voltage porcelain insulators made from Tanzania ceramic materials
(NM-AIST, 2019-03)
The study has evaluated the dielectric and mechanical strength of high voltage porcelain insulators made from Tanzania local ceramic raw materials. The ceramic raw materials involved were; Pugu Kaolin Same clay, vermiculite, ...
Simulation, performance analysis and improvements of solar farm installation in Tanzania
(NM-AIST, 2019-04)
With the environmental advantages of solar energy, the use of solar photovoltaic (PV) in electricity generation is encouraged by Tanzanian governments, however, the number of institutions that are benefiting from installing ...
Biodiesel production from parinari curatellifolia seeds oil using basic heterogeneous catalyst derived from tamarindus indica fruit shells
(NM-AIST, 2019-03)
Biodiesel is an alternative fuel to mineral diesel. It is produced from abundant and easily available renewable resources of animal fats and vegetable oil. However, the cost of oil feedstock is the major obstacle towards ...
Removal of heavy metals from water by capacitive deionization electrode materials derived from chicken feathers
(NM-AIST, 2019-03)
Capacitive deionization (CDI) is an emerging desalination technology based on the principle of electrical double layer capacitors. When the voltage is applied to the surface of the electrodes, electrodes become oppositely ...
