  1. 16. High-rate reactive magnetron sputter deposition and characterization of metal oxide films

    Författare :Maryam Kharrazi Olsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Molybdenum oxide films with good electrochromic properties were produced by single- and dual-target sputtering. Dual-target deposition was shown to be able of yielding optically functional films at much higher rates than that for single-target depositions. LÄS MER

    Författare :Shelley Brown; Göran Lindbergh; Robert Spotnitz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lithium-ion battery; LixNi0.8Co0.15Al0.05O2; LixMn2O4; LiyC6; ageing; three-electrode measurements; impedance modelling; surface film characterisation; hybrid electric vehicle; low-earth-orbit satellite; litiumjonbatteri; åldring; treelektroduppställning; impedansmodell; ytfilmskarakterisering; hybridfordon; satelliter; Electrochemistry; Elektrokemi;

    Sammanfattning : Lithium-ion batteries are a possible choice for the energy storage system onboard hybrid electric vehicles and low-earth-orbit satellites, but lifetime performance remains an issue. The challenge is to diagnose the effects of ageing and then investigate the dependence of the magnitude of the deterioration on different accelerating factors (e.g. LÄS MER

  4. 18. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion

    Författare :Jiajian Zhu; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High-speed photography; Laser diagnostics; Planar laser-induced fluorescence; Plasma-assisted combustion; Non-thermal plasmas; Gliding arc discharge; Optical diagnostics; Particle tracking velocimetry; Fysicumarkivet A:2015:Zhu;

    Sammanfattning : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. LÄS MER

  5. 19. Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua

    Författare :Alfredo Mendoza; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; electrical resistivity; surface water; springs; Nicaragua; Hydrogeology; groundwater; teknisk geografi; geographical and geological engineering; Hydrogeologi;

    Sammanfattning : Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. LÄS MER

  7. 20. The sense of well-being in a group of patients with gastro-intestinal cancer

    Författare :Christina Forsberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gastro-intestinal cancer; health-related quality of life; well-being; coping; Sense of Coherence; Health Index; nursing; rehabilitation.;

    Sammanfattning : The main purpose of this study was to describe patients with gastrointestinal cancer and their general health and well-being during different stages of the disease. Questionnaires concerning coping ability, general health, well-being and the frequencies and occurrences of symptoms were used to collect data about the patient's pre- and post-surgical situation.
