3. 17. 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.

   Sammanfattning : The outstanding properties of graphene make it attractive ink filler for conductive inks which plays an important role in printed electronics. This thesis focuses on the ink formulation based on graphene and graphene oxide (GO).Liquid phase exfoliation of graphite is employed to prepare graphene dispersions, i.e. LÄS MER

5. 19. Fully Printed Chipless RFID Tags towards Item-Level Tracking Applications

   Författare :Botao Shao; Lirong Zheng; Smail Tedjini; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chipless RFID tag; configurability; inkjet printing; time domain; frequency domain; paper substrate; tag antenna; linearly tapering; LC resonator;

   Sammanfattning : An ID generating circuit is unquestionably the core of a chipless RFID tag. For convenience of printing process and cost consideration, the circuit should be kept as simple as possible. LÄS MER

7. 20. Aqueous graphene dispersions for paper packaging

   Författare :Wei Zhao; Anwar Ahniyaz; Abhilash Sugunan; Thomas Gillgren; Johan A. Larsson; Zhi-Bin Zhang; Shi-Li Zhang; Valeria Nicolosi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; Aqueous graphene dispersions; Noncovalent interactions; Composites; Barriers; Inkjet printing; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

   Sammanfattning : Graphene is widely touted as the thinnest and the most versatile material available. As an atomically thin layer of carbon atoms arranged in a hexagonal configuration, graphene has a combination of technologically important properties, such as thermal and electrical conductivity, mechanical strength, and impermeability to gases.
