   Abstract : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.

5. 3. Electrokinetic devices from polymeric materials

   Author : Katarina Bengtsson; Nathaniel D Robinson; Mats Fahlman; Jörg P. Kutter; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : There are multiple applications for polymers: our bodies are built of them, plastic bags and boxes used for storage are composed of them, as are the shells for electronics, TVs, computers, clothes etc. Many polymers are cheap, and easy to manufacture and process which make them suitable for disposable systems.

6. 4. Engineering 3D degradable pliable scaffolds for adipose tissue regeneration : Advancing cell-material interactions by understanding the influence from thermal, chemical, mechanical properties and scaffold design

   Author : Shubham Jain; Anna Finne-Wistrand; Kamal Mustafa; Mikael Hedenqvist; Lauren Flynn; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradable polymers; 3D scaffolds; adipose tissue regeneration; cell-material interaction; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : In soft tissue defects that arise due to trauma, tumor resections and complex burns, a significant loss in adipose tissue remains a considerable challenge due to the insufficient regenerative capacity of the tissue. This thesis focuses on assessing cell-material interactions between degradable 3D polymer scaffolds with different designs and adipose tissue-derived stem cells. READ MORE
