  1. 16. Optimization of a one-part geopolymerization method for lab-scale, using waste glass wool as a precursor

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Oscar Enander; [2022]
    Keywords : Materials chemistry; Geopolymer; Glass wool; Recycling; Curing time; Curing temperature; Cement; Chemistry;

    Abstract : Geopolymers are amorphous inorganic polymeric structures. They are used as binding agents and can be compared to cementitious materials such as ordinary Portland cement. This thesis aims to produce geopolymers from waste glass wool. Today glass wool is found in isolation, both thermal and sound insulation, and it is not being recycled. READ MORE

  3. 17. Development of Nickel-Titanium Shape Memory Alloys using Electron Beam Melting

    University essay from KTH/Materialvetenskap

    Author : Georgios Manolios; [2022]
    Keywords : ;

    Abstract : In this project, the effect of electron beam melting on the behavior of NiTi shape memory alloyshas been studied, with focus on the effects of recycling powder within the process and theprocess parameters used and how “smoking” is affected. Flowability, powder characteristicsand chemical composition have been evaluated using imaging analysis techniques, Hallflowmeter measurements, FT4 powder rheometry and energy dispersive X-ray spectroscopyboth in virgin powder and in recycled powders.

  4. 18. Powder Rheology within AM production : Evaluating Compressibility, Permability, & Aeration for 316L Powders Within SLM Processes

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : André Leo; [2022]
    Keywords : Powder rheology; AM; Additive manufacturing; BPF; Powder bed fusion; SLM; Selective laser melting; FT4 powder rheometer; Compressibility; Permeability; Aeration; Pulver reologi; AM; Additiv tillverkning; BPF; Pulver bed fusion; SLM; Selektiv lasersmältning; FT4 pulver reometer; kompressibilitet; permeabilitet; luftning;

    Abstract : Additive manufacturing with the use of metals have been a steadily increasing field, being able to create products with a higher degree of complexity than traditional processing techniques. SLM is a popular AM process that uses metal powder as feedstock, and one of the key components of this process is the powder rheology. READ MORE

  5. 19. Characterization of Metal Powders in Electron Beam Powder Bed Fusion : Regarding particle size distribution of the finished part

    University essay from KTH/Materialvetenskap

    Author : Mattias Jerhamre Engström; Saman Sharif Hedås; [2022]
    Keywords : ;

    Abstract : As the manufacturing industry looks for better ways to create complex parts using sustainable and efficient methods, the additive manufacturing sector is taking a step forward. Additive manufacturing brings with it a large reduction in material used and the complex structures that can be created are not something to overlook. READ MORE

  6. 20. Compositional analysis of the Andean fruit Pouteria Lucuma : a comparison of different physical forms (powder, frozen pulp and fresh pulp)

    University essay from SLU/Department of Molecular Sciences

    Author : Elsa Ramberg; [2022]
    Keywords : Pouteria Lucuma; Powder; frozen pulp; fresh pulp; Total phenolic compounds; Antioxidant capacity; D-glucose; D-fructose and Sucrose.;

    Abstract : Lucuma (Pouteria Lucuma), an ancient fruit from the Andes, is now increasing in popularity in the global West due to the characteristic flavour and nutritional composition (e.g. high in fibres and phenolic compounds). The shelf life of the fresh fruit is short, therefore it is mainly used as frozen pulp or powder. READ MORE
