1. 6. Flexural strength of dental restoratives

   Master-uppsats, Umeå universitet/Institutionen för odontologi

   Författare :Mikael Blennow; Ahmed Al-Ahmed; [2023]
   Nyckelord :Flexural strength; porosity;

   Sammanfattning : Background: New dental restorative material, “Cention Forte” and “Admira Fusion” have been available on the market for quite some time but are still new in comparison with traditional resin-based composite, “Ceram.x Spectra ST” and glass ionomer cement, “GC Fuji II LC”. LÄS MER

3. 7. Material Experience Mycelium-Based Composite : Study of local biodegradable materials in combination with Mycelium

   Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

   Författare :Emelie Kjellqvist; [2023]
   Nyckelord :Mycelium; Mycelium Based Composite; MBC; Fungi; Material Drive Design; MDD; Mycologi; Material Experience; Lignocellulose;

   Sammanfattning : Mycelium-based composite (MBC) is being developed and researched in multiple commercial markets as an alternative sustainable material. MBC utilizes the mycelium ability to create a web-like structure in lignocellulosic structures. LÄS MER

4. 8. Evaluation of a computational method for natural fiber-reinforced plastics

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Anna Lim; [2023]
   Nyckelord :PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

   Sammanfattning : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. LÄS MER

5. 9. Combustibility study of resin for warm magnet coils used at CERN

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

   Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

7. 10. Investigation of Antenna Radomes in Low Earth Orbits

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

   Författare :Mathias Manohar Gren; [2023]
   Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

   Sammanfattning : 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.
