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. Development of a DEM-FEM framework for infrastructure simulations

   Master-uppsats, Göteborgs universitet / Institutionen för fysik

   Författare :Anita Ullrich; [2022-09-20]
   Nyckelord :;

   Sammanfattning : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. LÄS MER

4. 3. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

   Författare :Qianhui Liu; [2022]
   Nyckelord :Ambient pressure x-ray photoelectron spectroscopy; Event-averaging; Pd 100 surface structure oscillation; Physics and Astronomy;

   Sammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

5. 4. Thermal transients study for the ESS target helium cooling system

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Hannes Björk; [2022]
   Nyckelord :ESS; European Spallation Source; models; Modelica; system identification; sensors; cooling system; Technology and Engineering;

   Sammanfattning : The European Spallation Source (ESS) is going to be the worlds most powerful spallation source once in full operation. The neutrons used by scientists and engineers are spallated from a rotating wheel of wolfram, being bombarded by accellerated protons. LÄS MER

7. 5. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Haoyang Dong; [2022]
   Nyckelord :borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Sammanfattning : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. LÄS MER
