1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Grigore-Leon Ratiu; [2024]
   Keywords : Physics and Astronomy;

   Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

3. 2. Stability improvement to a ruthenium catalyst for partial oxidation of methane

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Melker Axelsson; [2023]
   Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

   Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

4. 3. Chronicled in metal : The biography of a trefoil brooch and the importance of object modification in Viking Age Sweden

   University essay from Uppsala universitet/Arkeologi

   Author : Isac Löfgren; [2023]
   Keywords : Trefoil brooch; Vikings; Viking Age; object biography; ornamentation;

   Abstract : Trefoil brooches are one of the most abundant types of Viking Age jewellery in Scandinavia. This thesis delves into the journey of one such brooch, known as 555783, discovered in Birka, Sweden. READ MORE

5. 4. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Christina Henricson; [2023]
   Keywords : ;

   Abstract : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. READ MORE

6. 5. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : Erik Stålbrand; [2023]
   Keywords : Solid Mechanics; Material Modelling; Damage Modelling; Sheet Metal Damage; Punching Simulation; Forming Simulation; Heat Exchanger; Technology and Engineering;

   Abstract : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.
