  4. 4. Optical properties of novel semiconductor nanostructures

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Stanislav Filippov; Linköpings universitet.; Linköpings universitet.; [2014]

    Abstract : Semiconductor nanostructures, such as one-dimensional nanowires (NWs) and zerodimensional quantum dots (QDs), have recently gained increasing interest due to their unique physical properties that are found attractive for a wide variety of applications ranging from gas sensing and spintronics to optoelectronics and photonics. Here, especially promising are nanostructures based on compound semiconductors, including ZnO, GaNP and GaAs/InAs. READ MORE

  5. 5. On CNS injury and olfactory ensheathing cell engraftment strategies

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : I-Hui Lee; Karolinska Institutet.; Karolinska Institutet.; [2005]

    Abstract : The intrinsic regenerative capacity of the adult mammalian central nervous system (CNS) is limited because of lack of nerve-growth stimulatory factors and presence of an insurmountable molecular environment for injured axons. This thesis aims to study neural regeneration following adult CNS injury, using rodent models of spinal cord injury, dorsal root avulsion, and Parkinson s disease. READ MORE
