2. 11. Material perception and action : The role of material properties in object handling

   Author : Kristin Ingvarsdottir; Kognitiv modellering; []
   Keywords : HUMANIORA; HUMANITIES; material perception; visual properties; motor planning; cognition; humanoid robot;

   Abstract : This dissertation is about visual perception of material properties and their role in preparation for object handling. Usually before an object is touched or picked-up we estimate its size and shape based on visual features to plan the grip size of our hand. READ MORE

4. 12. Surface analysis of low dimensional materials : revealing their electronic properties by advanced spectroscopy

   Author : Vladimir Miranda la Hera; Thomas Wågberg; Eduardo Gracia-Espino; Tomas Edvinsson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-dimensional materials; surface science; surface-sensitive techniques; angle-resolved photoemission spectroscopy; ultraviolet photoemission spectroscopy; electronic properties;

   Abstract : Low-dimensional materials (0D, 1D, 2D) have been widely used to develop modern miniaturized (micro- and nano-) technology. The use of these materials come from their extraordinary optical, electrical, thermal, and mechanical properties, which are very different from the bulk crystal. READ MORE

5. 13. On the influence of Si on anodising and mechanical properties of cast aluminium alloys

   Author : Baiwei Zhu; Caterina Zanella; Salem Seifeddine; Peter Leisner; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; anodising; corrosion protection; mechanical properties; Al-Si-baserade gjutningslegeringar; anodisering; korrosionsskydd; mekaniska egenskaper;

   Abstract : The combination of two cost-effective processes, i.e. casting and anodising, would be an interest for the aluminium component applications. However, there are some obstacles in the application of anodising on cast Al alloys. READ MORE

6. 14. Material Properties of Cereal Protein Films

   Author : Thomas Gillgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasticization; avenin; prolamin; kafirin; mechanical properties; water vapour permeability; oxygen permeability; protein; film; glass transition temperature; zein;

   Abstract : Materials that are renewable and biodegradable are demanded due to environmental aspects. Biopolymeric materials, such as materials from prolamins, fulfil both of these requirements. Prolamins are cereal storage proteins. Examples of such are zein, gluten, kafirin and avenin from maize, wheat, sorghum and oats, respectively. READ MORE

7. 15. As-cast AZ91D magnesium alloy properties : Effects of microstructure and temperature

   Author : Hoda Dini; Anders E.W. Jarfors; Nils-Eric Andersson; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnesium; Magnesium Alloy; AZ91D; High-Pressure Die-Casting; Mechanical Property; Microstructural Characterisation; Physical Modelling; Dislocations; Distortion; Residual Stress; Magnesium; Magnesiumlegering; AZ91D; Pressgjutna; Mekanisk Egenskap; Mikrostrukturkarakterisering; Fysikalisk Modellering; Flytspänning; Dislokationer; Geometrisk Tolerans; Restspänning;

   Abstract : Today, there is an essential need for lightweight, energy-efficient, environmentally benign engineering systems, and this is the driving force behind the development of a wide range of structural and functional materials for energy generation, energy storage, propulsion, and transportation. These challenges have motivated the use of magnesium alloys for lightweight structural systems. READ MORE
