1. 1. Quantifying liquid food waste : levels of liquid coffee waste, its causes and barriers and drivers for quantification in the Swedish food service sector

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Rosa Hellman; [2024]
   Nyckelord :sewage food waste; beverage waste; direct measurement; hospitality; restaurant; serving waste; food waste cause;

   Sammanfattning : Food waste is a waste of resources required throughout the entire supply chain, leading to environmental impacts that could have been avoided. Coffee has a relatively high environmental impact partially due to the high consumption. To identify levels and sources of food waste, and consequently prevent it, quantification is used. LÄS MER

3. 2. Developing a protocol for 3D-printable bioink from decellularised porcine tissue

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Vendela Sandin; [2024]
   Nyckelord :Scaffold; Extracellular matrix; ECM; Bioink; Bioprinting; Collagen; Pharmaceutical technology; Technology and Engineering; Biology and Life Sciences;

   Sammanfattning : T-cell administration via a scaffold is a promising tool for treatment of inoperable solid tumours. Traditional scaffold materials lack the complexity of the extracellular matrix (ECM) that cells normally grow in. An alternative is to instead use decellularised ECM (dECM) from biological tissue to create the scaffold. LÄS MER

4. 3. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Ryoi Takamatsu; [2023]
   Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

   Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

5. 4. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Arjun Monga; [2023]
   Nyckelord :coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

   Sammanfattning : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. LÄS MER

7. 5. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Vikramjeet Das; [2023]
   Nyckelord :rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

   Sammanfattning : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. LÄS MER
