  1. 16. Characterization of Amino Acid Transporters in the Brain : Molecular and Functional Studies of Members within the Solute Carrier Families SLC38 and SLC6

    Författare :Maria Hägglund; Robert Fredriksson; Farrukh Chaudhry; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amino acid transporter; Solute Carrier; Glutamine; Leucine; SNAT; B0AT; Neuroscience; Neurovetenskap;

    Sammanfattning : Solute carriers (SLCs) comprise the largest group of transporters in humans and there are currently 52 SLC families. They are embedded in cellular membranes and transport numerous molecules; defects in many of the genes encoding SLCs have been connected to pathological conditions, and several SLCs are potential drug targets.

  3. 17. Carrier dynamics in semiconductor quantum dots

    Författare :Jörg Siegert; Ari Friberg; Jesper Mørk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum dots; photoluminescence; time-resolved; spectroscopy; semiconductor; Optics; Optik;

    Sammanfattning : This thesis presents results of time-resolved photoluminescence experiments conducted on several different self-assembled InGaAs/GaAs and InAs/GaAs semiconductor quantum dot (QD) structures. Depending on the application in mind, different structural, electronic or optical properties have a different weight of importance. LÄS MER

  4. 18. Coordination of cross-carrier truck platooning

    Författare :Alexander Johansson; Jonas Mårtensson; Karl H. Johansson; Hani Mahmassani; KTH; []

  7. 20. Carrier Lifetime Relevant Deep Levels in SiC

    Författare :Ian Don Booker; Einar Sveinbjörnsson; Erik Janzén; Anthony Peaker; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon carbide; Deep level transient spectroscopy; Deep level; Carrier lifetime; Time-resolved photoluminescence;

    Sammanfattning : Silicon carbide (SiC) is currently under development for high power bipolar devices such as insulated gate bipolar transistors (IGBTs). A major issue for these devices is the charge carrier lifetime, which, in the absence of structural defects such as dislocations, is influenced by point defects and their associated deep levels.
