Methylammonium tin iodide perovskite: structural, electronic and thermodynamic properties by a DFT study with different exchange–correlation functionals
(Springer Nature Switzerland AG., 2020-03-20)
Lead-free perovskites have drawn much attention of researchers in the field of electronics and photovoltaics due to the toxicity issue of the lead halide perovskites. The methylammonium tin iodide CH3NH3SnI3 amongst others ...
Demand-SideManagement of Solar Microgrid Operation: Effect of Time-of-Use Pricing and Incentives
(Hindawi, 2020-06-05)
Over 17% of the world’s population lack access to electricity, the majority being in rural areas of sub-Saharan Africa and South
Asia. Microgrid technologies are a promising solution towards rural and remote area ...
Release Kinetic Models of Vanillin and Physicomechanical Properties of Thermoplastic Starch and Chitosan Nanocomposite Films: Effects of Mixing Order
(Springer Nature Switzerland AG., 2020-02-20)
The effects of mixing sequence of starch–chitosan nanocomposite films on antimicrobial properties of vanillin, the release kinetics of vanillin, and physicomechanical changes of films have been reported. Four types of films ...
Analysis of spatio-temporal climate variability of a shallow lake catchment in Tanzania
(IWA Publishing, 2020-04-06)
This study analyzed the trends and spatio-temporal variability in rainfall and temperature, and the length of the rainy season (LRS) in the Lake Manyara catchment, Tanzania, covering a period between 1988 and 2018 using ...
Investigation of optoelectronic properties of triphenylamine-based dyes featuring heterocyclic anchoring groups for DSSCs’ applications: a theoretical study
(Springer Nature Switzerland AG., 2020-08-05)
Design and synthesis of new potent sensitizers are of interest for realization of high-efficiency Dye Sensitized Solar Cells (DSSCs). Modification of the triphenylamine-based dyes by introducing suitable anchoring groups ...
Cryptogamic Packed Biofilter as Potential Adsorbent for CO2, NH3, and H2S Impurities from Biogas
(Hindawi, 2020-07-07)
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 is extremely toxic. There are various methods ...
Trends towards Effective Analysis of Fluorinated Compounds Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
(Hindawi, 2021-02-03)
Increased demand for monitoring and identification of novel and unknown fluorinated compounds (FCs) has demonstrated the need of sensitive fluorine-specific detectors for unknown FCs in both biological and environmental ...
Predicting land use/cover changes and its association to agricultural production on the slopes of Mount Kilimanjaro, Tanzania
(Taylor & Francis Online, 2021-01-11)
Increasing demand for food production results in Land use and land cover (LULC) changes, which afflicts the provision of ecosystem services in high mountain areas. This work used time-series LULC and selected spatial metrics ...
Drivers, Impacts and Mitigation of Increased Sedimentation in the Hydropower Reservoirs of East Africa
(MDPI, 2021-06-16)
Hydropower reservoirs are essential for the climate-neutral development of East Africa.
Hydropower production, however, is threatened by human activities that lead to a decrease in water
storage capacity of reservoirs. ...
Building Climate Change Adaptation and Resilience through Soil Organic Carbon Restoration in Sub-Saharan Rural Communities: Challenges and Opportunities
(MDPI, 2021-10-02)
Soil organic carbon (SOC) is widely recognised as pivotal in soil function, exerting important controls on soil structure, moisture retention, nutrient cycling and biodiversity, which in turn underpins a range of provisioning, ...
