1. 6. Foaming of Some Cellulose Derivatives - Initial Studies

   Författare :Kristina Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological characterisation; Foaming; hydroxypropyl methylcellulose HPMC ; scale-up production; ethyl hydroxyethyl cellulose EHEC ; hot-mould baking; cellulose derivatives; extrusion;

   Sammanfattning : Fossil-based polymeric foams, based on polymers such as polystyrene and polyurethane, are important and widely employed materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. There are however a few disadvantages with these foamed products. LÄS MER

3. 7. Model-based Analysis and Design of Atomic Layer Deposition Processes

   Författare :Anders Holmqvist; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomic layer deposition; Heterogeneous reaction kinetics; Limit-cycle dynamics; Parameter estimation; Multi-objective optimization; Dynamic optimization; Scale-up analysis;

   Sammanfattning : Atomic layer deposition (ALD) is a thin-film manufacturing process in which the growth surface is exposed to non-overlapping alternating injections of gas-phase chemical precursor species separated by intermediate purge periods to prevent gas-phase reactions. ALD is characterized by sequential self-terminating heterogeneous reactions between highly reactive gas-phase precursor species and surface-bound species which, when allowed sufficient conditions to reach saturation, results in highly conformal films, on both planar and topographically complex structures.

4. 8. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose

   Författare :Andreas Rudolf; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Fermentation; Lignocellulose; Hydrolysis; Bioethanol;

   Sammanfattning : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Artificial intelligence; Computer vision; Robotic visual perception; Human-robot collaboration; AI; Assembly; Automotive industry; HRC; Flexible automation;

   Sammanfattning : Industry faces an urgent need for prospective solutions to scale up assembly automation, a challenge that requires immediate attention. In contemporary manufacturing, industrial robots need more intelligence to qualify for increasingly demanding flexible automation tasks. LÄS MER

7. 10. Design of flexible lattice structures : a design for additive manufacturing perspective

   Författare :Satabdee Dash; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design for additive manufacturing; DfAM; Lattice structures; Flexibility; Compuational methods; Numerical modelling; Engineering design process;

   Sammanfattning : Recent years has seen an unprecedented growth in emerging technologies like Additive manufacturing (AM), augmenting the manufacturing capabilities through a multitude of opportunities while also introducing unique constraints, such as support structures, and post-processing requirements. Taking full advantage of the potential of AM demands product designs to be optimised for both opportunities and constraints specific to AM, requiring evolution from the traditional design for manufacturing to design for additive manufacturing (DfAM).
