  2. 2. Catalytic formation of ammonia from nitric oxide

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Emma Adams; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NOx reduction; Passive-SCR; In situ characterisation; Environmental heterogeneous catalysis; Ammonia formation;

    Sammanfattning : The emission of nitrogen oxides (NOx) from automobiles results in severe environmental and biological effects. Passive selective catalytic reduction (passive SCR) of NOx with ammonia (NH3) is a proposed method for abatement of NOx emissions in net lean-burn gasoline passenger vehicles. LÄS MER

  3. 3. Absorption non-uniformity characterisation and its impact on flexographic ink distribution of coated packaging boards

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Sofia Thorman; Karlstads universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid absorption; Absorption non-uniformity; Characterisation; Measurement technique; Print Mottle; Flexography; Coated packaging boards; Chemical Engineering; Kemiteknik;

    Sammanfattning : There are high demands on flexographic print quality to be sufficiently high and consistent in order to create a competitive packaging. At the same time the production efficiency need to be high. Printers thus need to achieve the same quality every time and quickly start-up new printing jobs. LÄS MER

  5. 5. Labelling of various macromolecules using positron emitting 76Br and 68Ga Synthesis and characterisation

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ulrika Yngve; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; 76Br; Radiobromination; Prosthetic Groups; Macromolecules; Oligonucleotides; 68Ga; PET; Octreotide; Metal Chelates; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Different prosthetic groups containing a trialkylstannyl- and an electrophilic group have been synthesised and labelled with the accelerator produced 76Br (T1/2=16 h) through oxidative bromination. The labelled prosthetic groups were conjugated to amino-containing macromolecules such as proteins and 5´-modified oligonucleotides. LÄS MER
