  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. Green Protein Hydrogels and Non-dry Aerogels in Water Purification

    University essay from KTH/Kemi

    Author : Emanuel Nelsson Vedung; Alexander Singh; Julia Wadefjord; [2022]
    Keywords : Aerogel; Hydrogel; Whey Protein Isolate; Water purification; Adsorption; Sustainability;

    Abstract : Having access to clean water is not a certainty for every human being. Today, there are major problems with polluted water that not just affect us humans, but also the ecosystem around us. In recent years, research into making aerogels from protein nanofibrils (PNF) has increased. READ MORE

  4. 3. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Oscar Enander; [2022]
    Keywords : Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Abstract : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. READ MORE

  5. 4. Greening practices in Swedish municipal planning : A comprehensive analysis of Upplands Väsby’s Detailed Development Plans

    University essay from KTH/Urbana och regionala studier

    Author : Mariana Laterrade; [2022]
    Keywords : Planning; Ecosystem services; Green infrastructure; Nature-based solutions Green and blue elements and structures; Stockholm County; Detailed Development Plans; Upplands Väsby; Planering; Ekosystemtjänster; Grön infrastruktur; Naturbaserade lösningar Gröna och blå element och strukturer; Stockholms län; Detaljplaner; Upplands Väsby;

    Abstract : Increasing urbanization is pressing and degrading our ecosystems and compromising future generations. This scenario is expected to worsen unless significant action is scaled up. At the same time, the urban areas have the opportunity to be part of the solution, leading to a more resilient and sustainable future. READ MORE

  6. 5. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE
