2. 16. Numerical and Experimental Investigations of the Machinability of Ti6AI4V : Energy Efficiency and Sustainable Cooling/ Lubrication Strategies

   Author : Salman Pervaiz; Cornel Mihai Nicolescu; Hazim El-Mounayri; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloys; Energy consumption; Wear mechanisms; Finite element analysis; computational fluid dynamic analysis; Production Engineering; Industriell produktion;

   Abstract : Titanium alloys are widely utilized in the aerospace, biomedical,marine, petro-chemical and other demanding industries due to theirdurability, high fatigue resistance and ability to sustain elevateoperating temperature. As titanium alloys are difficult to machine, dueto which machining of these alloys ends up with higher environmentalburden. READ MORE

4. 17. Development and evaluation of hybrid joining for metals to polymers using friction stir welding

   Author : Wallop Ratanathavorn; Arne Melander; Stefan Hallström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloy; thermoplastic; friction stir welding; dissimilar joining; Production Engineering; Industriell produktion;

   Abstract : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. READ MORE

5. 18. Standardized architectures for information integration and life cycle management in the domain of production engineering

   Author : Navid Shariat Zadeh; Bengt Lindberg; Erik Herzog; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Engineering; Industriell produktion;

   Abstract : While design and management of production systems based on digital models brings benefits, the communication of models comes with challenges since models typically reside in a distributed heterogeneous IT environment using different syntax and semantics. Coping with heterogeneity requires an appropriate integration strategy and methodology. READ MORE

6. 19. Development of biocatalytic processes for selective antioxidant production

   Author : Io Antonopoulou; Paul Christakopoulos; Ulrika Rova; Evangelos Topakas; Anne S. Meyer; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and sugar residues in plant cell walls.

7. 20. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production

   Author : Johannes Yayo; Antonius J. A. van Maris; Richard Sparling; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; ethanol; glucose; fructose; amino acids; pyrophosphate; chaotropicity; thermodynamic driving force; laboratory evolution; chemostats; metabolic engineering; Biotechnology; Bioteknologi;

   Abstract : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.
