1. 1. The active phase of Pt(110) during catalytic CO oxidation

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

   Author : Hira Qazilbash; [2024]
   Keywords : Physics and Astronomy;

   Abstract : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. READ MORE

3. 2. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

   Author : Kasper Malmborn; [2023]
   Keywords : Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

   Abstract : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. READ MORE

4. 3. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Jonas Beling; [2023]
   Keywords : ion; physics; ion physic; scattering; desorption; sputtering; jon; fysik; jonfysik;

   Abstract : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. READ MORE

5. 4. Techno-economic analysis of a waste-to-energy system using innovative pyrolysis process

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Hannah Sofie Perrens; [2023]
   Keywords : Waste management; pyrolysis; heat and power generation; decentralized energy systems; waste-to-energy;

   Abstract : Waste management is of growing concern with increasing amount of municipal waste generation and the industry standards are becoming stricter due to climate goals and sustainable development. Waste-to-energy (WTE) systems in the form of waste incineration have been promoted as a low-carbon energy source, but nevertheless have high greenhouse gas (GHG) emissions. READ MORE

6. 5. Nanoscale characterisation of model Ni-Mo catalyst active phases

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Jonas Elmroth Nordlander; [2022]
   Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

   Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE
