1. 1. Transient state UV spectroscopy of Tyrosine and Tyrosine-containing protein

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Hongjian Chen; [2023]
   Nyckelord :Tyrosine; Calmodulin; Autofluorescence; Transient-state monitoring; Electronic state transitions; Tyrosin; Calmodulin; Autofluorescens; Transient-tillståndsövervakning; Elektroniska tillståndsövergångar;

   Sammanfattning : The aromatic amino acids tryptophan, tyrosine, and phenylalanine have been extensively used for different label-free protein studies. These investigations extract information on protein conformations and interactions from the emitted fluorescence's intensity, wavelength, and/or polarization. LÄS MER

3. 2. Synthesis of Fluorescent Analogues of FluoBar1 for Studying Protein Expression Rates in Living Cells

   Master-uppsats, Uppsala universitet/Organisk kemi

   Författare :Victor Hellgren; [2022]
   Nyckelord :;

   Sammanfattning : L-type voltage gated calcium channels are membrane bound ion channels that regulate the intracellular concentration of calcium ions as a response to changes in the membrane potential. They exist in four isoforms and recent studies have brought extra attention to the Cav1. LÄS MER

4. 3. High Accuracy Relative Luminescence Quantum Yield Measurements of Upconverting Nanoparticles

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

   Författare :Björn Thomasson; [2016]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 4. The Influence of Xylan on Precipitation and Filtration Properties of Lignin : A Study in the Context of the LignoBoost Process

   Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

   Författare :Helen Schneider; Lynn Schneider; [2016]
   Nyckelord :Xylan; Lignin; Precipitation; FBRM; LignoBoost process;

   Sammanfattning : The LignoBoost process is a valuable supplement to the Kraft process. It can increase the pulp production rate of a Kraft mill and it enables lignin separation from black liquor with a high degree of purity. However, residual xylan in black liquor has been observed to increase filtration resistance of lignin during the LignoBoost process. LÄS MER

7. 5. Development of an Upconverting Nanoparticles Quantum Yield Measurement System

   Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Meng Li; [2016]
   Nyckelord :UCNPs; upconverting nanoparticles; QY; quantum yield; fluorescence; luminescence; Physics and Astronomy;

   Sammanfattning : Fluorescence imaging is a growing biomedical technique; it can be used to localize the luminescent biomarkers inside the tissue. Lanthanide-doped upconverting nanoparticles (UCNPs) are promising luminescent probes for multiple applications in biophotonics. They allow acquiring autofluorescence-free recordings with high spatial resolution. LÄS MER
