1. 1. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

   Master-uppsats, Linköpings universitet/Industriell miljöteknik

   Författare :Christian Rotter; Erik Fagerberg; [2023]
   Nyckelord :additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

   Sammanfattning : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. LÄS MER

3. 2. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Douglas Björkengren; [2023]
   Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Lukas Scmid; Paula Borst; [2023]
   Nyckelord :;

   Sammanfattning : As a global manufacturer of commercial vehicles, Scania is aiming for delivering high-quality products to its customers. Therefore, testing the produced components before assembling the final product and delivering it to the customer is key. LÄS MER

5. 4. Fouling modelling in a UHT unit based on plant data.

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

   Författare :Thai Lam; [2023]
   Nyckelord :UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Sammanfattning : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. LÄS MER

7. 5. Start-up of a Kistler 9129AA dynamometer on a custom rotation machine and investigation of its potential eligibility for cutting force measurement in wood

   Master-uppsats, Luleå tekniska universitet/Träteknik

   Författare :Frank Schleicher; [2023]
   Nyckelord :dynamometer; cutting forces in wood; rotation machine; wood cutting;

   Sammanfattning : In the manufacturing industry, the mechanics of metal-cutting is well-understood and used to improve cutting processes. The mechanics of wood-cutting are still in its early stages and further research is required. LÄS MER
