  1. 1. Prototyping of an automated cyclic Neutron Activation Analysis setup

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Cornelius Maurer; [2022]
    Nyckelord :Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

    Sammanfattning : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. LÄS MER

  3. 2. LIGHTING MASTER PLANFOR MARCHAMALOSALT FLATS

    Magister-uppsats, KTH/Ljusdesign

    Författare :Raquel Garcia Rodriguez; [2019]
    Nyckelord :Low impact; darkness; holistic approach; natural protected realm; heritage; alternative urban lighting solutions; smart controls;

    Sammanfattning : The Marchamalo salt flats, built in the 18th century, are located near Cabo de Palos, Murcia (Spain), in a hot spot area with constant pressures of tourism and urban speculation. The salt flats are currently abandoned, but its landscape and ecological value still subsist. LÄS MER

  4. 3. Development and Investigation of an Automated Temperature Calibration for Temperature Phosphors

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Xin Xu; [2012]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This thesis achieves a semi-automatic temperature calibration for thermographic phosphors. Thermocouple temperature information and phosphorescence decay curves are recorded synchronized and continuously while the oven temperature is ramped across the entire temperature range. LÄS MER

  5. 4. Investigations on Detector Non-Linear Response for the Optimization of Laser-Induced Phosphorescence Decay-Time Detection.

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Fahed Abou Nada; [2011]
    Nyckelord :avalanche photodiode; photodetector; non-linear detector response; phosphorescence; thermographic phosphor; photomultiplier tube; decay-time; time-gated detector; Physics and Astronomy;

    Sammanfattning : This thesis investigates the nonlinear detector response to Laser Induced Phosphorescence signal originating from the CdWO4 phosphor. A matrix method is utilized to map the detectors linearity for decay-time determination as function of detector gain and number of photons reaching the detector. LÄS MER

  7. 5. Excitation transfer between conjugated polyelectrolytes and triplet emitter confined in protein nanowires

    Master-uppsats, Linköpings universitet; Biomolekylär och Organisk Elektronik

    Författare :Chorpure Thinprakong; [2010]
    Nyckelord :Singlet Triplet Förster Dexter Phosphorescent Amyloid PTAA Iridium;

    Sammanfattning : Phosphorescent metal complexes can be incorporated into amyloid-like fibrils, and these fibrils can be decorated with conjugated polyelectrolytes (CPEs). In this study, fac-tris[2-phenylpyridinato-C2,N]irdium(III) complexes [Ir(piq)3] were used as the phosphorescence emitter and Sodium-poly(3-thiophene acetic acid) (PTAA-Na) compounds were used as CPEs.
