1. 26. Liquid-Phase Exfoliation of Two-Dimensional Materials : Applications, deposition methods and printed electronics on paper

   Författare :Viviane Forsberg; Magnus Norgren; Luis Miguel Pereira Nunes; Mittuniversitetet; []
   Nyckelord :molybdenum disulfide MoS2 ; transition metal dichalcogenide TMD ; thin films; inkjet printing; 2D inks; liquid-phase exfoliation; shear exfoliation; printed electronics; organic electronics; PEDOT:PSS; photoresponse; photocurrent; cathodoluminescence;

   Sammanfattning : After the unprecedented success of graphene research, other materials that can also be exfoliated into thin layers, like Transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), have also become the subjects of extensive studies. As one of the most promising methods for large scale production of such materials, liquid-phase exfoliation (LPE) has also been the subject of extensive research and is maturing as a field to the point that devices using additive manufacturing and printed nanosheets are often reported.

3. 27. Living with diabetes during transition to adult life- Relationships, support of self-management, diabetes control and diabetes care

   Författare :Carina Sparud Lundin; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescents; young adults; type 1 diabetes; paediatric diabetes care; adult diabetes care; diabetes care utilization; transition; glycemic control; grounded theory;

   Sammanfattning : The overall aim of the thesis was to illuminate main concerns related to the transition of adolescents/ emerging adults with Type 1 diabetes to adult life and diabetes care and to gain a deeper understanding of how care providers, patients and their parents handle this situation. In paper I and II, participant observations of visits to physicians, nurses and group sessions (n=51) were conducted in two paediatric (PDC) and two adult (ADC) diabetes clinics as well as interviews with care providers (n=10).

4. 28. Phase-field modeling of stress-induced precipitation and kinetics in engineering metals

   Författare :Claudio F. Nigro; Christina Bjerkén; Ylva Mellbin; Pär A T Olsson; Reinhart Pippan; Malmö universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-field theory; finite element method; corrosion; finite volume method; phase transformation; hydride; hydrogen embrittlement; linear elastic fracture mechanics;

   Sammanfattning : The formation of brittle compounds in metals operating in corrosive environments can be a tremendous source of embrittlement for industrial structures and such phenomenon is commonly enhanced in presence of stresses. To study this type of microstructural change modeling is preferred to experiment to reduce costs and prevent undesirable environmental impacts. LÄS MER

5. 29. Miniature Phase-Transistion Actuators

   Författare :Lena Klintberg; Lars Montelius; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Sammanfattning : Clearly, there is a need for simple, strong actuators capable of large strokes in miniaturized systems such as valves and optical shutters.The basis for this work is the microstructure technology with processing techniques adopted from the integrated circuit industry. LÄS MER

7. 30. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C

   Författare :Jens Emmerlich; Wolfhard Möller; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin solid films; Single-crystal; Physics; Fysik;

   Sammanfattning : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. LÄS MER
