Fish bladder-based activated porous carbon/co3o4/tio2 composite electrodes for supercapacitors
(NM-AIST, 2020-02)
Supercapacitors as energy storage devices depend on electrode materials, electrolyte and
conductive additives. In relation to the above, this master’s dissertation specifically provides
a scientific understanding and ...
Lawsone, lawsone ether and bilawsone for dyesensitized solar cells application
(NM-AIST, 2020-02)
Dye-sensitized solar cells (DSSCs) had turned up as a novel class of low-cost solar cells that
can be fabricated easily compared to silicon solar cells. The DSSCs based on natural sensitizers
are able to generate clean ...
Impact of climate change on groundwater recharge in lake Manyara catchment
(2020-08)
This study aimed to estimate the groundwater recharge of the Lake Manyara catchment (7920 km2) in two different time intervals, historical 1988-2018 and near-future 2021-2050 climatic condition. This study analyzed the ...
Removal of hydrogen sulfide from biogas using red rock materials
(NM-AIST, 2020-03)
In this study, the potential of red rock materials for the removal of hydrogen sulfide from biogas
was studied. The rock samples were collected, sieved and organized in various particle size
ranges such as 0.32 - 250 µm, ...
Assessment of levels and distribution of progesterone in receiving waters and wastewaters in the vicinity of Arusha city,Tanzania
(NM-AIST, 2020-12)
This study aimed at investigating the levels and distribution of progesterone in receiving waters
and wastewaters in Arusha, a fast-growing urban area and third largest city in Tanzania. Also,
intend to assess the ...
Production of biodiesel from neem seed oil using calcinated banana ash/ li-cao/fe2(so4)3 blends as a catalyst
(2020-08)
Biodiesel is a possible remedy to the present toxic, finite sources and ever-diminishing crude
fuels. Non-edible and locally available (Azadirachta indica) Neem Seed Oil (NSO) as a
second-generation feedstock was transformed ...
Theoretical and experimental studies of imidazolium based ionic liquids for supercapacitors application
(2020-03)
The theoretical study of neutral ion pairs of 1-ethyl-3-methylimidazolium tetrafluoroborate
([EMIM][BF4]) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide
([EMIM][NTf2]) has been performed. The formation ...
Cryptogamic packed biofilter as potential adsorbent for co2, h2s and nh3 impurities from biogas
(NM-AIST, 2020-07)
The presence of elevated concentrations of carbon dioxide, hydrogen sulfide, ammonia and trace impurities in biogas affect its caloric value as well as causes corrosion and are extremely toxic. There are various methods ...
Effect of industrial dust deposition on photovoltaic module performance: Experimental measurements in tropical region
(NM-AIST, 2020-02)
Dust particles accumulation affects photovoltaic module transmittance of photovoltaic solar cell
glazing, and thus leading to substantial reduction of conversion efficiency owing to lower
irradiance reaching the surface. ...
Efficacy of silver nanoparticles in capacitive deionization electrodes as antimicrobial agents
(NM-AIST, 2020-02)
The availability of clean and safe water is still a big challenge in most parts of the world.
Drinking water should be free of harmful microorganisms and should contain the required
amount of minerals based on the set ...
