  1. 1. Development and Application of Single-Ended Picosecond Laser Diagnostics

    Författare :Billy Kaldvee; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Raman Scattering; Temporal Filtering; Picosecond Laser Diagnostics; Rayleigh Scattering; Laser-spectroscopy; DIAL; Laser Combustion Diagnostics; Lidar; Laser-induced Fluorescence; Laser-induced Incandescence; Fysicumarkivet A:2012:Kaldvee;

    Sammanfattning : Light detection and ranging (lidar), a method for nonintrusive, single-ended, and range resolved measurements, has been developed and applied for combustion related diagnostics. Employing picosecond laser pulse durations and detectors providing temporal resolution on the order of picoseconds, lidar has been applied successfully for both quantitative temperature- and species concentration measurements, obtaining an ultimate range resolution of 0.

  3. 2. Objective quantification and analysis of eating behaviour associated with obesity development : from lab to real-life

    Författare :Billy Langlet; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: The last four decades have seen a marked increase in childhood and adult obesity prevalence, attributed to an “obesogenic” environment. Several genetical, environmental and behavioural factors have been identified that increase the risk of obesity, but treatment outcomes are usually modest and the risk of relapse high. LÄS MER

  5. 4. Simulating Earthquake Rupture and Near-Fault Fracture Response

    Författare :Billy Fälth; Björn Lund; Roland Roberts; Harald Hökmark; Eric Dunham; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered. LÄS MER

  7. 5. Exploring cellulose as a biomacromolecule for enhanced battery metal ion recovery/recycling

    Författare :Billy W. Hoogendoorn; Richard Olsson; Yuanyuan Li; Mikael S. Hedenqvist; Aji Mathew; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomacromolecules; Nanocellulose; metal oxide nanoparticle synthesis; electrodeposition; battery recycling; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The research focused on the effects of integrating nanocellulose in the solidification of metal ions into metal oxide particles or metallic electrodeposits.  Firstly, the cellulose was isolated as highly crystalline ca. 15-25 nm thick and 500 nm long fibers from bacterial cellulose using acid hydrolysis and had a negative surface charge.
