1. 11. Possibilities and Challenges in Temporal Control of XUV Pulses by Opto-optical Modulation

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Anna Olofsson; [2018]
   Keywords : Quantum Control; Atomic physics; ultrashort pulses; attosecond science; ultrafast optics; nonlinear optics; opto-optic modulator; Physics and Astronomy;

   Abstract : Recent developments in opto-optical modulation technique calls for improved temporal control of light modulation processes of coherent XUV light. This thesis project evaluates an experimental method aimed at achieving redirection and amplitude modulation of XUV-light, by using precise determination of decay times in states of noble gases that are deemed suitable for opto-optical control.

3. 12. Study of Fluorescence Dye for Tracing Lubrication Oil inside Marine Engines

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : David Sanned; [2017]
   Keywords : Laser Induced Fluorecence; Lubrition Oil; Marine Engines; Flourescence Dye; Technology and Engineering; Physics and Astronomy;

   Abstract : Engine lubrication is very important for engine sustainability and efficiency. It becomes even more important when heavier fuel types who contributes to lubrication are changed to alternative fuel without the same lubrication abilities. READ MORE

4. 13. Screening for adsorptions of Calbindin D9k and Monellin proteins to Silica nanoparticles

   University essay from Lunds universitet/Examensarbeten i molekylärbiologi

   Author : Nora Klynning; [2017]
   Keywords : Biology and Life Sciences;

   Abstract : Although nanoparticles (NPs) are very small, their field in science is currently growing very large. There are several biological, medical and technical applications possible for NPs when bound to proteins. Protein-NP interactions are difficult to predict and therefore a lot of fundamental research is yet to be completed. READ MORE

5. 14. High Accuracy Relative Luminescence Quantum Yield Measurements of Upconverting Nanoparticles

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Björn Thomasson; [2016]
   Keywords : Upconverting Nanoparticles; Biomedical imaging; Luminescence tomography; Luminescence imaging; Engineering; Physics; Engineering Physics; Photonics; Cancer; Cancer detection; Cancer diagnostics; Laser Engineering; quantum yield; imaging; upconverting; Biophotonics; Single Point Tomography; Relative Luminescence Quantum Yield Measurements; Energy transfer upconversion; Nanoscience; Luminescence; Imaging of biological tissue; Upconversion; Beam profile evaluation; Beam profile; UCNP; UCNPs; Nanoparticles; Technology and Engineering;

   Abstract : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. READ MORE

6. 15. Interferometric Charecterization of Supersonic Gas-Jets for Laser Wakefield Acceleration

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Jonatan Henriksson; [2016]
   Keywords : Interferometry; Laser Wakefield Acceleration; Mach-Zehnder; Gas-Jet characterization; Physics and Astronomy;

   Abstract : The Multi-Terawatt laser at the LLC (Lund Laser Centre) is used to accelerate particles using laser wakefield acceleration. Laser wakefield acceleration is a particle acceleration method that utilizes intense electric fields in plasma created by high intensity laser pulses when passing through gas. READ MORE
