1. 6. Additively Manufactured Rare Earth Free Permanent Magnets

   University essay from Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Oorganisk kemi

   Author : Himesha Abenayake; [2023]
   Keywords : additive manufacturing; MnAl; MnAl C ; rare earth free permanent magnets; selective laser melting; SLM; MnAl-based permanent magnets;

   Abstract : It’s well known that MnAl(C) material consists of a metastable phase (τ) with promising ferromagnetic properties, produced either by controlled cooling from the high-temperature hexagonal ε-phase or rapid cooling that freezes the ε-phase followed by low-temperature annealing. Due to the high cooling rates involved, additive manufacturing (AM) especially selective laser melting (SLM), has been identified as a possible method to retain the high-temperature ε-phase, hence containing a potential capacity to produce permanent magnets upon low-temperature annealing.

3. 7. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Christopher Pourier; [2023]
   Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

   Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

4. 8. Pre-study and Conceptual Design of a Hydrogen Fuel Cell Driven Wheel Loader

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Jana Caspari; Pijus Bernatavicius; [2022]
   Keywords : PEM fuel cell; hydrogen; drive cycle analysis; large-size wheel loader; architecture generation; packaging;

   Abstract : Volvo Construction Equipment is one of the leading construction machinery manufacturers in the world. To stay amongst the leaders, research and development projects for new technologies are crucial. The most important path of development today is the reduction of emissions produced by these heavy duty vehicles. READ MORE

5. 9. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Fredrik Plane; [2022]
   Keywords : Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

   Abstract : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. READ MORE

6. 10. Carbon dioxide-based pump system for portable HPLC equipment

   University essay from Uppsala universitet/Mikrosystemteknik

   Author : Sofia Göransson; [2022]
   Keywords : Microsystem Technology; Flow Chemistry; Chemical Analyses; High-Performance Liquid Chromatography; HPLC; Pump System; Miniaturise; Portable; Pressurised Carbon Dioxide; PCO; High-Pressure;

   Abstract : To make chemical analysis available both practically and economically, one approach is to miniaturise the equipment needed for the analysis. High-performance liquid chromatography (HPLC) is an example of a flow chemistry analysis system where active work is performed to achieve miniaturised systems. READ MORE
