   Författare :Bei Wang; Klas Hjort; Zhigang Wu; Magnus Berggren; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser patterning; sacrificial mask; liquid metal; strain sensor; skin movement; masking; shrink film; 3D conformal masking; liquid metal particles; soft electronics; stretchable electronics; compliant electronics; skin-like electronics; epidermal electronics; micro-heater; particle sintering; enteroendocrine cells; localized ectopic expression; wettability; flexography printing; conformal transfer printing; hydro printing; plant physiology; drosophila;

   Sammanfattning : Skin-like electronics could provide a soft and gentle contact with living beings for perceiving and delivering the information of pressure, strain, temperature with higher spatial resolution and sensitivity than our skin, without disturbing the user. Gallium-based liquid metal (LM) is an excellent material for soft and stretchable skin-like devices, since it has high electrical and thermal conductivity, flowability, and self-healable capability.

3. 17. 3D Printed scaffolds as cancer microenvironment medels for drug discovery

   Författare :Jennifer Rosendahl; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D Printing; Breast cancer; Biomaterials; Drug development;

   Sammanfattning : Cancer is one of the most common diseases in the modern world and major efforts are made globally to develop new diagnostics and treatments. It originates from a cell which, at some point, has begun to divide and grow uncontrollably. The most common type is breast cancer, and like all other cancers there is a need of more efficient drug therapies. LÄS MER

   Sammanfattning : 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. 19. Nanocellulose based 3D printed hydrogel scaffolds for cartilage and bone regeneration : Tuning of composition, pore structure and functions

   Författare :Sahar Sultan; Aji P. Mathew; Lennart Bergström; Gustav Nyström; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose materials; 3D printing; gradient biphasic hydrogel scaffolds; metal-organic frameworks; hydroxyapatite; cartilage and bone regeneration; osteochondral scaffolds; materialkemi; Materials Chemistry;

   Sammanfattning : Biobased-materials with customized scaffolds have played a prominent role in the success of tissue engineering (TE). Cellulose nanomaterials (CNM) isolated from the abundant biopolymer, cellulose, is explored in this thesis for TE engineering due to its versatile properties such as biocompatibility, high specific strength, surface functionality and water retention capacity.

7. 20. Inkjet Printing of Graphene-based Microsupercapacitors for Miniaturized Energy Storage Applications

   Författare :Szymon Sollami Delekta; Mikael Östling; Jiantong Li; Donald Lupo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; graphene; supercapacitor; microsupercapacitor; energy storage; printed electronics; printing technologies; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Printing technologies are becoming increasingly popular because they enable the large-scale and low-cost production of functional devices with various designs, functions, mechanical properties and materials. Among these technologies, inkjet printing is promising thanks to its direct (mask-free) patterning, non-contact nature, low material waste, resolution down to 10 µm, and compatibility with a broad range of materials and substrates.
