2. 1. Leveraging supplier material data to inform LCA modelling and resource assessment in the automotive industry

   Author : Felipe Bitencourt de Oliveira; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment LCA ; vehicle gliders; metal availability; metal scarcity; life cycle inventory LCI ; automotive industry; International Material Data System IMDS ;

   Abstract : This thesis investigates the application of supplier material composition data from the automotive industry's International Material Data System (IMDS) to inform sustainability assessments. A methodology is developed to systematically extract and process IMDS data for use in life cycle assessment (LCA) modelling. READ MORE

4. 2. Qualification of Metal Additive Manufacturing in Space Industry : Challenges for Product Development

   Author : Christo Dordlofva; Anna Öhrwall Rönnbäck; Peter Törlind; Ola Isaksson; Marco Bertoni; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Space industry; Product Development; Qualification; Design for Additive Manufacturing;

   Abstract : Additive manufacturing (AM), or 3D printing, is a collection of production processes that has received a good deal of attention in recent years from different industries. Features such as mass production of customised products, design freedom, part consolidation and cost efficient low volume production drive the development of, and the interest in, these technologies.

5. 3. Sheet metal forming in the era of industry 4.0 : using data and simulations to improve understanding, predictability and performance

   Author : Sravan Tatipala; Johan Wall; Christian Johansson; Tobias Larsson; Mehdi Tarkian; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Simulation; Industry 4.0; Sheet Metal Forming; Process Monitoring; Process Control; Automation; Finite Element Analysis; Smart Manufacturing; Mechanical Engineering;

   Abstract : A major issue within automotive Sheet Metal Forming (SMF) concerns ensuring desired output product quality and consistent process performance. This is fueled by complex physical phenomena, process fluctuations and complicated parameter correlations governing the dynamics of the production processes. READ MORE

6. 4. Requirement and Availability of Scarce Metals for Fuel-Cell and Battery Electric Vehicles

   Author : Ingrid Råde; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal requirement; sustainability; fuel cells; batteries; platinum; metal scarcity; resources; electric vehicles; metal availability; industrial ecology;

   Abstract : Battery and fuel-cell electric vehicles (EVs) are considered as a means to meet some of the environmental and resource challenges of todays road vehicle system. EVs have the potential for zero tailpipe emissions as well as an energy efficiency higher than internal combustion engine vehicles and they can be flexible concerning primary energy source.

7. 5. Cobalt in the hard metal production industry : exposure via inhalation and skin and the inflammatory response in human keratinocytes

   Author : Maria Klasson; Eva Särndahl; Håkan Westberg; Magnus Lindberg; Alexander Persson; Kristina Jakobsson; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cobalt; cobalt chloride; skin; HaCaT; in vitro; cell viability; pro-inflammatory cytokines; NLRP3 inflammasome;

   Abstract : Cobalt is a strong sensitizer and can cause contact allergy upon both direct contact or from airborne exposure on the skin. In the skin, keratinocytes are the first cells to come in contact with the metal and will react and respond to the danger by triggering an alarm system resulting in an inflammatory response in the skin.
