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. Designing a reactive feedback feature for end-users in web-based media software

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Jessica Dellmar; [2024]
   Keywords : User Feedback; End-user involvement; Usability; Design Thinking; User Experience;

   Abstract : Customer feedback is essential for improving a company's products or services and increasing customer satisfaction. Despite its value, user involvement faces many challenges, such as low user motivation and feedback with missing context information. READ MORE

4. 3. Prospects for a Free Electron Laser at the FemtoMAX Beamline

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

   Author : Johan Holmberg; [2024]
   Keywords : Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Abstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

5. 4. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Carl Pontén; [2024]
   Keywords : Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

   Abstract : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

6. 5. Optimering av flyghastighet för flygplan

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Louise Larsson; [2023]
   Keywords : Aircraft flight speed; flight operations; speed optimization; Cost Index; ECON speed; Flyghastighet; flygverksamhet; hastighetsoptimering; kostindex; ekonomisk hastighet;

   Abstract : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. READ MORE
