1. Teachers' Retention in Tanzanian Remote Secondary Schools : Exploring Perceived Challenges and Support
Sammanfattning : Teacher retention is a global challenge, and many developed and developing countries are struggling to staff and retain teachers in schools, particularly in low-performing, remote, and less desirable areas. In most of these countries, Tanzania in particular, the efficacy of fiscally inclined teachers’ retention strategies continues to be dubious. LÄS MER
2. Deactivation of Catalysts and Reaction Kinetics for Upgrading of Renewable Oils
Sammanfattning : The transport sector is one of the main contributors of greenhouse gas emissions in the world. Advanced biofuels from renewable oils can play a decisive role in reducing carbon emissions from the transport sector. Advanced biofuels from waste streams like tall oil, used cooking oil etc. LÄS MER
3. Three-dimensional structured carbon foam : synthesis and applications
Sammanfattning : Recently, due to the unique properties and structures such as large geometric surface area, electrical conductivity and light weight, 3D structured carbon materials have been attracting extensive attention from scientists. Moreover, the materials, which can provide well-defined pathways for reactants to easily access active sites, are extremely useful for energy conversion as well as environmental and catalysis applications.

4. Membrane Electrode Assemblies Based on Hydrocarbon Ionomers and New Catalyst Supports for PEM Fuel Cells
Sammanfattning : The proton exchange membrane fuel cell (PEMFC) is a potential electrochemicalpower device for vehicles, auxiliary power units and small-scale power plants. In themembrane electrode assembly (MEA), which is the core of the PEMFC single cell,oxygen in air and hydrogen electrochemically react on separate sides of a membraneand electrical energy is generated.

5. Cobalt catalyst supports for Fischer-Tropsch synthesis
Sammanfattning : In the Fischer-Tropsch (FT) synthesis, CO and H2 (synthesis gas) are converted into hydrocarbons that can be further upgraded to high-quality fuels and chemicals. Different carbon sources such as natural gas, coal and biomass can be used as feed-stocks for the synthesis gas. LÄS MER
