Innovations and Sustainability: The Case of Improved Biomass Stoves' Adoption and Use in Tanzania
(Lund, Sweden – Spring, 2009)
The adoption and continued use of improved stoves in the developing countries is of social, economic
and environmental concern. In most developing countries, biomass-based energy accounts for more
than 90% of all household ...
Theoretical Study of Structure, Vibration Spectra and Thermodynamic Properties of Cluster Ions in Vapors over Potassium, Rubidium and Cesium Chlorides
(Springer Nature Switzerland AG., 2011-10-04)
The geometrical structure, the frequencies of normal vibrations, and the thermodynamic characteristics of tri- and pentaatomic cluster ions M2Cl+, MCl 2 − , M3Cl 2 + , and M2Cl 3 − (M = K, Rb, or Cs) existing in saturated ...
Theoretical study of the structure and stability of the Na2Cl+, NaCl 2−, Na3Cl 2+, and Na2Cl 3− ions
(Springer Nature Switzerland AG., 2007-11)
The geometrical parameters, normal vibration frequencies, and thermochemical characteristics of the Na2Cl+, NaCl 2−, Na3Cl 2+, and Na2Cl 3− ions in saturated vapors over sodium chloride were calculated by the ab initio ...
Understanding the Emergence and Functioning of River Committees in a Catchment of the Pangani Basin, Tanzania
(Water Alternatives, 2011-06)
In this paper we explore the emergence and functioning of river committees (RCs) in Tanzania, which
are local water management structures that allocate and solve water conflict between different water users
(smallholder ...
Natural Dye Sensitizer for Grӓtzel Cells: Sepia Melanin
(Science and Education Publishing, 2015)
The efficiency of Grätzel cell can be further improved by the anchoring groups, such as COOH to be adsorbed onto the TiO2 surface with a large electronic coupling. Some of the most efficient sensitizers are synthetic dyes ...
Morphological and Chemical Composition Characterization of Commercial Sepia Melanin
(Science and Education Publishing, 2015)
Melanins are difficult to characterize because of their intractable chemical properties and the heterogeneity in their structural features. Melanin pigments, in fact, are composed of many different types of monomeric units ...
Theoretical study of properties of Cs2Cl+, CsCl2−, Cs3Cl2+, and Cs2Cl3− ions: Effect of Basis set and Computation Method
(Rwanda Journal, 2012-07)
Theoretical study of properties of Cs2Cl+, CsCl2−, Cs3Cl2+ and Cs2Cl3− ions has been performed using the density functional theory (DFT/B3LYP) and the second order Møller-Plesset perturbation theory (MP2). Two triple-zeta ...
Study of interaction of chitosan with Fluoride
(Biointerface Research in Applied Chemistry, 2018-06-15)
Interaction of chitosan with fluoride (F-
) has been studied using experimental and computational methods. Chitosan was extracted from
prawns shells and modified by cross-linking with glutaraldehyde and protonation using ...
Semi-Transparent Building Integrated Photovoltaic Solar Glazing: Investigations of Electrical and Optical Performances for Window Applications in Tropical Region
(Hindawi, 2019-12-17)
Integrating solar PV technology with semi-transparent windows permits multifunctional operation as electricity generation and allowing natural light to enter the building, hence overall energy efficiency improvement. The ...
A study on Pb removal kinetics using modified agricultural wastes from Tanzania
(Springer Nature Switzerland AG., 2020-10-29)
Lignocellulosic materials, abundant and renewable materials, are gaining popularity as metal scavenging agents because of their high sorption capacities, relatively low cost and environmental-friendliness. However, there ...
