Biogas slurry derived mesoporous carbon/metal oxides composites for supercapacitors application
(NM-AIST, 2017-12)With the increasing utilities of intermittent renewable energies, hybrid electric vehicles and portable electronic devices, supercapacitors have been identified as one of the solution for energy storage since they can ... -
Canarium schweinfurthii resin as an organic binder for carbonized briquettes
(NM-AIST, 2022-07)Charcoal is the predominant fuel used in many developing countries for domestic and commercial purposes. Transport and handling of charcoal produces fines amounting to 10-20% by weight. The fines can be turned into ... -
Climate and anthropogenic footprints implications on the surface and groundwater dynamics on the southern slopes of Mount Kilimanjaro, Tanzania
(NM-AIST, 2021-10)Climate and land use/cover changes impact water resources all over the world. This study aimed at developing a conceptual understanding and management of the impacts of present and future climate change and human ... -
Combination of natural betanidin dye with synthetic organic sensitiser towards dye-sensitised solar cell application
(NM-AIST, 2023-05)Betanidins belong to natural red-purple pigments betacyanins, which experimentally demonstrated good light adsorption in a visible range and might be suitable for the dye sensitised solar cell (DSSCs). Instability is a ... -
Controlling ammonia and sulfide inhibition during anaerobic digestion of slaughterhouse waste
(NM-AIST, 2021)The performance of experimental batch-reactor loaded with slaughterhouse waste at mesophilic temperature was investigated as well as the inhibition of both ammonia and sulfide in the aqueous phase during phase I of ... -
Design of controlled release fertilizers on the base of polymeric, nanoclays and nanocomposite excipients
(2016-04)It was hypothesised that agronomically suitable controlled release fertilizers (CRFs) can be prepared using synthetic and/or natural biopolymers and polymer-clay nanocomposite excipients. Literature has focused almost ... -
Development of a suitable pragmatic and cost effective biomonitoring method for assessing water pollution in tropical African rivers
(NM-AIST, 2015-09)The needs of tropical African countries to develop their own biomonitoring indices using local macroinvertebrates as opposed to adoption or relying on non-tropical indices in biomonitoring programmes for assessing freshwater ... -
An eco-friendly tanning method using plant barks and their combination with aluminium sulphate from kaolin for leather industry
(NM-AIST, 2021-02)Chrome tanning has remained the most preferred tanning method worldwide in the leather industry because it produces leather of a high quality with all the desired features. However, environmental concerns of chromium ... -
Evaluation of selected botanicals as insecticides against cabbage insect pests in Tanzania
(NM-AIST, 2022-06)Synthetic pesticides are frequently and unwisely used to control cabbage insect pests by smallholder farmers despite the environmental pollution and insect pests’ resistance development. This work assessed the insecticidal ... -
Fenton-mediated solar-driven photocatalysis of industrial dye effluent with polyaniline impregnated with activated TiO2-Nps
(Elsevier, 2024)Various integrated technologies have been investigated for the remediation of heavily polluted industrial dye effluent. Also, more than 70 % of these dyes are known to be solely azo dyes used in the textile industry ... -
Geological and hydro-geochemical assessment of fluorine around mount Meru, northern Tanzania
(NM-AIST, 2020-03)Areas around Mt. Meru are among the areas in Tanzania where climate change, population growth and high fluoride levels in much of the water sources lower availability of water for domestic ... -
Hydrologic responses to climate and land use/cover changes in world heritage site of Ngorongoro conservation area and surrounding catchments, northern Tanzania
(NM-AIST, 2023-01)In Tanzania, various studies have analyzed the impact of climate and land use/cover changes on water resources. However, information on the interactions between climate and land use/cover change, temporal and spatial ... -
