1. Techno-economic analysis and simulation of low temperature district heating networks
University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöAbstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

2. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging
University essay from KTH/KemiAbstract : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. READ MORE

3. The black hole information paradox and holography
University essay from Uppsala universitet/Teoretisk fysikAbstract : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. READ MORE

4. Investigation of Antenna Radomes in Low Earth Orbits
University essay from Lunds universitet/Centrum för analys och syntesAbstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

5. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE
