2. 1. A comparative cost analysis of conventional wrought steel and powder metallurgy (PM) gear manufacturing technologies

   Author : Babak Kianian; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear manufacturing; Manufacturing cost analysis; Powder metallurgy PM ; Press and sintering P S ; Wrought steel conventional gear manufacturing; Decision support system DSS ; Sustainability; Sustainable production SP ; Automotive Industry;

   Abstract : The transportation industry landscape is going through a massive transformation due to trends such as autonomous and electrified vehicles. The electrification trend has already started to display its ample influence on the automotive industry. READ MORE

4. 2. Towards renewable chemicals production in cyanobacteria

   Author : Kateryna Kukil; Pia Lindberg; Yu Jianping; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synechocystis PCC 6803; metabolic engineering; succinate; phenylpropanoids; laboratory evolution; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Abstract : The intensive fossil fuel combustion by humanity resulted in the increase of atmospheric CO2 concentration creating the greenhouse effect, which in turn causes severe environmental problems. Thus, humanity should find solutions to decrease dependency on fossil hydrocarbons in order to lower CO2 emission into the atmosphere. READ MORE

5. 3. Harnessing the potential of filamentous fungi for sustainable and healthy food system

   Author : Neda Rousta; Mohammad J Taherzadeh; Duu-Jong Lee; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable food system; mycoprotein; bioactive compounds; L-carnitine; submerged fermentation; healthy food; edible filamentous fungi; Resource Recovery; Resursåtervinning;

   Abstract : Food systems have the potential to improve human health while contributing to environmental sustainability; however, they are currently endangering both. The current food system, which is often based on animal farming, is responsible for global greenhouse gas emissions, and increases the incidence of, and mortality from, non-communicable diseases.

6. 4. Metabolic engineering strategies to increase n-butanol production from cyanobacteria

   Author : Josefine Anfelt; Elton P. Hudson; Mathias Uhlén; Patrik R. Jones; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; biofuels; butanol; synthetic scaffold; CRISPRi; solvent tolerance; Bioteknologi; Biotechnology;

   Abstract : The development of sustainable replacements for fossil fuels has been spurred by concerns over global warming effects. Biofuels are typically produced through fermentation of edible crops, or forest or agricultural residues requiring cost-intensive pretreatment. READ MORE

7. 5. Hydrolases as Catalysts for Green Chemistry and Industrial Applications - Esterase, Lipase and Phytase

   Author : Yasser Gaber; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPLC-EAT; sustainable environment; mutation; metallo-enzyme; phytate; b-propeller; biodegraqdable; metrics; green chemistry; Novozym 435; CalB; solvent-free; kinetic resolution; Biocatalysis; rational design; PLE; esterase; clopidogrel; enantioselectivity;

   Abstract : The use of enzymes in industrial applications has been recognised for providing clean processes with minimal impact on the environment. This thesis presents studies on engineering of enzymes and enzyme-based processes in the light of green chemistry and environmental sustainability, and focuses on three hydrolases: esterase, lipase and phytase.
