1. 1. Identification and evaluation of solutions for long-haul electric road freight.

   University essay from Linköpings universitet/Logistik- och kvalitetsutveckling

   Author : Amanda Lundström; Gustav Lindén; [2023]
   Keywords : Electric road freight; long-haul; TCO; Tripple bottom line;

   Abstract : Road freight transportation is important for the development of the global economy and, at the same time, one of the most destructive businesses when it comes to the environment and human health. As societies evolve, the need for freight transportation increases and the transport demand cannot in a sustainable way be fulfilled with the use of diesel trucks as it is done today. READ MORE

3. 2. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Adam Jacobsson Trönndal; [2023]
   Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

4. 3. High resolution x-ray imaging by measuring the induced charge distribution

   University essay from KTH/Fysik

   Author : Zihui Jin; [2022]
   Keywords : Computed tomography; photon-counting detector; silicon; spatial resolution; Datortomografi; fotonräknande detektor; kisel; spatial upplösning;

   Abstract : Computed tomography (CT) is a medical imaging technique used to create cross-section images of human bodies based on x-rays. The emerging photon-counting CT detector shows several advantages compared with the traditional energy integrating detector. READ MORE

5. 4. Investigations of p-type quantum dots in GaSb nanowires

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : In-Pyo Yeo; [2021]
   Keywords : Physics and Astronomy;

   Abstract : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. READ MORE

6. 5. Electrical and Optical Characterization of InAsP/InP Nanowire-Based Avalanche Photodetectors

   University essay from Högskolan i Halmstad/Fotonik

   Author : Praveen Kumar Singaravelu; Tawhidul Alam Mohammad; [2016]
   Keywords : ;

   Abstract : The availability of new manufacturing methodology in solid state physics makes it possible to grow nano-photonic devices for better performance and unique properties. In this thesis work, we use I-V and FTIR spectroscopy to study the electrical and optical properties of InAsP/InP nanowire-based array avalanche photodetectors for near infrared applications.
