  2. 11. Hydrogen generation from dimethyl ether by autothermal reforming

    Author : Marita Nilsson; Lars Pettersson; Ann Cornell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; dimethyl ether; fuel cell; hydrogen; palladium; reforming catalyst; temperature-programmed reduction; truck idling; X-ray diffraction; zinc; Chemical engineering; Kemiteknik;

    Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE

  4. 12. Mesoporous material systems for catalysis and drug delivery

    Author : Aylin Atakan; Magnus Odén; Cristina Canal; Petra de Jongh; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Hybrid material systems possess multi-functional properties which make them intriguing for the materials science community since very early dates. However, it is not straightforward to produce such material systems. A smart and efficient approach is necessary to extract the desired properties of each component under the desired conditions.

  5. 13. Laser Diagnostics for Applications to In-Cylinder Engine Investigations

    Author : Robert Collin; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LII; Rayleigh scattering; formaldehyde; OH; soot; dimethyl ether; Laser technology; Fysik; Laserteknik; Physics; LIF; Laser diagnostics; combustion engines; Fysicumarkivet A:2004:Collin;

    Abstract : In the work presented in the thesis laser diagnostics was employed primarily in the investigation of engines, but was also used to study soot in flames. Quantitative measurements were performed for visualizing both in-cylinder soot formation and DME sprays in a combustion vessel. READ MORE

  6. 14. Anti-VEGF treatment of patients with diabetic macular edema : Studies of visual acuity, macular edema and patient-reported outcomes

    Author : Therese Granström; Janeth Leksell; Henrietta Forsman; Elisabet Granstam; Högskolan Dalarna; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hälsa och välfärd; Health and Welfare;

    Abstract : The aim of this thesis was to describe and evaluate visual acuity, macular edema and patientreported outcomes (PRO) following anti-VEGF treatment of diabetic macular edema (DME) patients in a real-world setting. Using a longitudinal study design, a cohort of DME patients was followed from baseline to 1 year after treatment start. READ MORE

  7. 15. Bio-refinery system integrated with pulp and paper mills using black liquor gasification

    Author : Muhammad Naqvi; Jinyue Yan; Mats Westermark; Klas Engvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bio-refinery; biomass; black liquor gasification; bio-fuel; pulp mill; CO2; coversion efficiency; integration; synthesis gas; Chemical engineering; Kemiteknik;

    Abstract : Mitigation of climate change and energy security are major driving forces for increased biomass energy utilization. The pulp and paper industry consumes a large proportion of biomass worldwide that include bark, wood residues, and black liquor. READ MORE
