1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

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

   Author : Grigore-Leon Ratiu; [2024]
   Keywords : Physics and Astronomy;

   Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

3. 2. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Máté Károly Tóth; [2023]
   Keywords : Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

   Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

4. 3. Fano Resonances in Time-Dependent Wells

   University essay from Uppsala universitet/Materialteori

   Author : Anton Gregefalk; [2023]
   Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

   Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

5. 4. Magnetic field of the magnetic chemically peculiar star V1148 Ori

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Kristoffer Pettersson; [2023]
   Keywords : chemically peculiar star; magnetic fields; deconvolution; zeeman effect; polarization;

   Abstract : This project aims to obtain and interpret the measurements of the mean longitudinal magnetic field of the chemically peculiar star V1148 Ori. To achieve this aim 12 spectropolarimetric observations obtained by the CFHT using the spectropolarimeter ESPaDOnS were used. READ MORE

6. 5. Improving the experimental setup for ultrasound-optical tomography imaging

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ibtisam Dahir Ahmed; [2023]
   Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

   Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE
