  1. 1. Structured Carbon-Alkaline Earth Metal Halides Composites for Ammonia Storage

    Författare :Zhejian Cao; Farid Akhtar; Mamoun Taher; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ammonia; MgCl2; SrCl2; graphene foam; porous structure; Materialteknik; Engineering Materials;

    Sammanfattning : NOx (NO, NO2) is one of the most harmful air-pollutants from exhaust, resulting in series of environmental problems as well as severe healthy issues for human beings. Selective catalytic reduction (SCR) system is a common approach to eliminate NOx onboard by using ammonia as a reductant. LÄS MER

  3. 2. Structured Ammonia Carriers for Selective Catalytic Reduction

    Författare :Zhejian Cao; Farid Akhtar; Andreas Kaiser; Peizhong Feng; Louise Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ammonia; SCR; NOx; graphene network; zeolite; MOF; Engineering Materials; Materialteknik;

    Sammanfattning : Air quality has been one of the long-term focuses in society and has raised people’s concern regarding its amelioration in the post coronavirus disease 2019 (COVID-19) pandemic era. Nitrogen oxides (NOx), including NO and NO2, as one of the most harmful air pollutants, have been stringently monitored in most countries due to their devastating impact on the environment and human health.

  4. 3. Electrochemical investigations on lipid cubic phases

    Författare :Mohammad Yaser Khani Meynaq; Britta Lindholm-Sethson; Solomon Tesfalidet; Ehud M. Landau; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. LÄS MER

  5. 4. Spontaneous imbibition and colloidal aspects of inkjet printing

    Författare :Asaf Oko; Per M. Claesson; Agne Swerin; Douglas Bousfield; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Water-based inkjet is one of the most abundant and versatile digital printing technologies. The subject of this thesis work is processes that take place once an inkjet drop lands on the surface of a porous printing media, with focus on liquid penetration due to capillary action (spontaneous imbibition) and aggregation of ink components.

  7. 5. Molecular dynamics in membrane systems : an ESR spin label study

    Författare :Magdalena Ehrström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The ESR spin labeling technique has been used to investigate order and motion in medel lipid systems and in biological membranes under various experimental conditions.The effects of CaCl2, MgCl2, LaCl3 and some alkali halides on B. LÄS MER
