  1. 31. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER

  3. 32. Biomonitoring of soil remediation workers´ exposure to polycyclic aromatic compounds (PACs) – method development and characterisation of PACs in blood

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Julia Jejdling; [2019]
    Nyckelord :occupational exposure; creosote; contaminated sites; gas chromatography-mass spectrometry GC-MS .;

    Sammanfattning : For a long period of time, it has been common to use creosote for impregnation of railroad ties. Creosote consists of 85% polycyclic aromatic hydrocarbons (PAHs), of which some are carcinogenic and/or mutagenic. LÄS MER

  4. 33. Development of a method that quantifies the filtration efficiency of soft particles in drop-in fuels

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Swarga Shriharsha; [2019]
    Nyckelord :;

    Sammanfattning : The global carbon footprint is increasing with course of time. World is moving towards fossil free and reduce the dependency of fossil fuels to meet their daily needs. Transportation industry is the major user of fossil fuels today and major contributor to the CO2 emissions which leads to global warming. LÄS MER

  5. 34. Induction of plant defence and secretion of volatile compounds by Colletotrichum acutatum in leaf infection assay of woodland strawberry

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Joubin Haji Mirza Ali; [2018]
    Nyckelord :Plant Defence; PAMP-triggered immunity; Colletotrichum acutatum; Anthracnose Disease; Pathogen; Fragaria vesca; Woodland Strawberry; Leaf Infection; Volatile Secretion; β-caryophyllene;

    Sammanfattning : Consumers demand healthy food with less residues of pesticides, in addition to the global awareness of the negative impact such chemicals have caused to the environment during the last decades. Farmers and other agricultural participants are far away from completely end up the usage of pesticides but currently used practice could stepwise be improved in pest management. LÄS MER

  7. 35. Characterization of soil remediation workers’ dermal exposure to polycyclic aromatic compounds

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Beatrice Johansson; [2018]
    Nyckelord :Tape-stripping; PAH; dermal exposure; soil remediation; GC-MS.;

    Sammanfattning : Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that are composed by at least two aromatic rings. PAHs can be found in coal and petroleum, but can also be formed from incomplete combustion of for example fossil fuels, tobacco, wood and when smoking food. LÄS MER
