2. 1. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

   Author : Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

   Abstract : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. READ MORE

4. 2. Micro-grinding of titanium

   Author : Mohammadali Kadivar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dressing; grinding; tool topography.; modelling; Micro machining;

   Abstract : Titanium and its alloys are difficult-to-cut materials, commonly used in several application fields, such as: medicine, aerospace, automotive and turbine manufacturing due to their biocompatibility, corrosion resistance, excellent mechanical and thermal properties, and light weight. However, its machining is associated with several difficulties, such as high tool wear, low surface quality, high cutting forces and high costs. READ MORE

5. 3. Educational choices of the future : a sociological inquiry into micro-politics in education

   Author : Goran Puaca; Högskolan i Borås; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Educational choice; Micro-politics; Want-formation; Habitus; Identity; Educational choice; micro-politics; want-formation; habitus; identity;

   Abstract : This thesis investigates how students’ practical considerations for future choices in education and occupations correspond to policy objectives of socially productive educational choices. This is conveyed through the primary aim of analyzing the correspondence between on the one hand educational policy intentions and on the other hand students’ educational choices and the social and cultural conditions that structure them.

6. 4. Micro-scale studies of wear

   Author : Rickard Gåhlin; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wear; micro-scale; methods; fundamental studies; AFM; micromechanical; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Abstract : The development of materials for tribological components is constantly striving to more sophisticated properties, specialised for specific applications. This progress requires and depends to a large extent on a parallel development of the theoretical knowledge of wear and on development of the experimental tools for investigating wear in the research lab as well as in the field.

7. 5. High Precision Micro-Grinding of Advanced Materials

   Author : Mohammadali Kadivar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ceramic; Additive manufacturing; Laser-assisted micro-grinding; Modeling; Surface integrity; Titanium; Micro-grinding; Process efficiency;

   Abstract : The aim of this thesis is to advance a fundamental understanding of process mechanics and surface integrity in micro-grinding of advanced materials, such as additively and conventionally manufactured titanium and engineering ceramic. Grinding forces and specific grinding energy were chosen as the two most important indicators to investigate the process. READ MORE
