1. On Gas Contaminants, and Bipolar Plates in Proton Exchange Membrane Fuel Cells
Sammanfattning : The proton exchange membrane (PEM) fuel cell is an electrochemical device that converts chemical energy into electrical energy through two electrocatalytic reactions. The most common catalyst used is platinum on carbon (Pt/C), which has shown the best performance in the fuel cell until now. LÄS MER
2. Application of Wastes from Pulp and Paper Industries for Steelmaking Processes
Sammanfattning : Over the past several years, considerable efforts have been made to develop a more circular economy. The ambition to reuse, remanufacture and recycle materials is of great significance for the establishment of a sustainable society. LÄS MER
3. Thermodynamic Database for Zirconium Alloys
Sammanfattning : For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption. LÄS MER
4. Geochemistry of the Kola River and Lake Imandra, northwestern Russia
Sammanfattning : The impact from mining and large-scale agricultural activities on levels and migration of metals within the Kola River and Lake Imandra has been studied in detail. Evaluation of the pollution status in the Kola River is based on sampling of the dissolved (0. LÄS MER
5. Kraft lignin valorization by hydrotreatment over Mo-based sulfided catalysts
Sammanfattning : The production of green fuels and chemicals from bio-based feedstock can suppress the dependency on fossil resources and help mitigate global climate challenges. Kraft lignin is a thermochemically modified natural lignin obtained from the pulping process as a byproduct. LÄS MER
