  1. 1. Novel catalysts development for NOx reduction from H2 combustion engines

    Författare :Jieling Shao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H2-SCR; SSZ-13 zeolite; in-situ DRIFTS; Iridium; Nitrogen selectivity; Platinum; reduction pretreatment; temperature intervals; BETA zeolite; Palladium;

    Sammanfattning : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. LÄS MER

  3. 2. Stability of UO2 in systems containing radiolytic oxidants : The role of uranyl peroxide species

    Författare :Junyi Li; Mats Jonsson; Peter Burns; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UO2; studtite; XPS; radiolysis; UO2; studtit; XPS; radiolys; Kemi; Chemistry;

    Sammanfattning : Nuclear power constitutes a major pillar on the global energy market, and it will most probably increase in importance as fossil fuels are gradually phased out. The main problem connected to nuclear power is the generation of highly radiotoxic spent nuclear fuel (95% UO2 and 5% radioactive fission products and heavier actinides). LÄS MER

  4. 3. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

    Författare :Mikael Danielsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

    Sammanfattning : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. LÄS MER

  5. 4. Engineering 3D degradable pliable scaffolds for adipose tissue regeneration : Advancing cell-material interactions by understanding the influence from thermal, chemical, mechanical properties and scaffold design

    Författare :Shubham Jain; Anna Finne-Wistrand; Kamal Mustafa; Mikael Hedenqvist; Lauren Flynn; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradable polymers; 3D scaffolds; adipose tissue regeneration; cell-material interaction; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In soft tissue defects that arise due to trauma, tumor resections and complex burns, a significant loss in adipose tissue remains a considerable challenge due to the insufficient regenerative capacity of the tissue. This thesis focuses on assessing cell-material interactions between degradable 3D polymer scaffolds with different designs and adipose tissue-derived stem cells. LÄS MER

  7. 5. Methylisothiazolinones. Diagnosis and prevention of allergic contact dermatitis

    Författare :Birgitta Gruvberger; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; venereology; Dermatologi; Dermatology; Prevention.; Chemical burns; Occupational dermatoses; Allergic contact dermatitis; Guinea pig maximization test; Isolation identification of contact sensitizers; Inactivation; Methylisothiazolinones; Kathon® CG; venereologi;

    Sammanfattning : Preservatives are biologically active substances which are required in water-based products/systems to prevent growth of micro-organisms. Kathon® CG (K-CG), one of several preservatives based on 5-chloro-2-methyl-4-isothiazolinon-3-one (MCI) and 2-methyl-4-isothiazolin-3-one (MI) has been shown to be a common sensitizer in dermatitis patients.
