   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Sara Christenson; [2023]
   Keywords : ;

   Abstract : In 2015, the United Nations adopted 17 different sustainability development goals. These goals were set for the global community to be guided by – but also to follow thus slowingdown climate change, prevent inequality, end poverty and make sure that by 2030 all people enjoy peace and prosperity.

4. 3. Cryogenic properties of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Patricio Piantanida; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; cryogenic;

   Abstract : The mechanical properties of three austenitic stainless steel alloys, namely 21-6-9, 316L and a modifed 316, fabricated via laser powder bed fusion, have been studied. From the results previously obtained through tensile tests at room and cryogenic temperatures, their strength and ductility were compared against similar conventionally processed materials.

5. 4. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

   University essay from Karlstads universitet

   Author : Shiniar Said Saleh; [2023]
   Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

   Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

6. 5. Towards a sustainable substitute for Acrylonitrile Butadiene Styrene (ABS) in automotive industry

   University essay from KTH/Fiber- och polymerteknologi

   Author : Amalia Christoula; [2023]
   Keywords : Polylactide PLA ; Biobased; Life Cycle Analysis LCA ; Impact modifiers; Lignocellulose nanofibers LCNF; Polylaktid PLA ; Biobaserad; Livscykelanalys LCA ; Slagtålighet; Nanofibrer av lignocellulosa LCNF ;

   Abstract : Syftet med detta examensarbete var att utveckla ett hållbart ersättningsmaterial till akrylnitrilbutadienstyren plast (ABS), genom att applicera principerna för grön kemi och teknik. ABS är en icke-nedbrytbar plast som till exempel används i slagtåliga produkter för hyttinteriörer. READ MORE
