  1. 21. Atomistic Modelling of Low Dimensional Materials for Energy Harvesting and Gas Sensing Applications

    Författare :S. Rabab Naqvi; Rajeev Ahuja; Abir De Sarkar; Uppsala universitet; []
    Nyckelord :Density functional theory; Low dimensional materials; Energy harvesting; Hydrogen storage; Gas Sensing; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Energy crisis and pollution are the two biggest issues of the present times which are extremely important to address on priority. Scientists/Researchers are trying to explore and create alternate means of energy production which are sustainable and free from greenhouse emissions. LÄS MER

  2. 22. Development of New Bacteria-Reducing Surfaces

    Författare :Josefin Illergård; Monica Ek; Lars Wågberg; Eva Blolmberg; Ute Römling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antibacterial; polyelectrolyte multilayers; polyvinylamine; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : In recent years, antibacterial surfaces have been a subject of increased interest. Especiallyinteresting are non-leaching, contact-active surfaces that physically disrupts the bacterialcell using immobilised cationic polymers. Thus the risks of bacterial resistance and discharge of hazardous biocides is minimised. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maritime transport; risk; accidents and incidents; Teknik; validation; Technological sciences; analysis; Dangerous goods; hazardous materials hazmat ; Keywords - Vol. I; packaging; management; assessment; framework; technique; validation.; marine environment; Keywords - Vol. II;

    Sammanfattning : Abstract - Vol. I In this Volume of the thesis, which consists of two volumes, a risk analysis framework for application in the maritime transport system of packaged dangerous goods (PDG) is presented. In many countries, dangerous goods risks have been ranked high among public concerns. LÄS MER

  4. 24. Utilization of waste materials for extraction of strategic metals : a biogeochemical approach

    Författare :Viktor Sjöberg; Stefan Karlsson; Bert Allard; Mattias Bäckström; Christian Ekberg; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biogeochemistry; ICP-QMS; MP AES; strategic metals; vanadium; uranium; mine waste; steel slag; shale residues; Enviromental Science; Miljövetenskap;

    Sammanfattning : Worldwide the modern society produces vast amounts of waste materials containing strategic and valuable metals. Some of them are of substantial economic or environmental significance if controlled recovery of metals can be performed or if uncontrolled release to the environment occurs. LÄS MER

  5. 25. Landfills and glass dumpsites as future bank accounts of resources : waste characterization and trace elements extraction

    Författare :Yahya Jani; William Hogland; Monica Odlare; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landfill mining; metals extraction; glass dumpsites; hazardous waste; chemical extraction; reduction-melting; Miljövetenskap; Environmental Science;

    Sammanfattning : Environmental pollution and health threats as well as scarcity of raw materials, water, food and energy are among the main challenges our world are now facing. Simultaneously, landfills and open dumpsites still are the dominant global waste disposal option even with their long term environmental impacts in case of greenhouse gases and contaminated leachates.
