2. 21. Graphene Based Inks for Printed Electronics

   Author : Man Song; Zhi-Bin Zhang; Helena Grennberg; Anwar Ahniyaz; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exfoliation; Graphene inks; Inkjet printing; Screen printing; GO Ag hybrid inks; Leuckart reaction; Reduction.; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : 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. READ MORE

4. 22. Microscale electrostatic 2D- and 3D-printing

   Author : Anton Karlsson; Stefan Johansson; Jonas Lindh; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrohydrodynamics; electrospraying; electrowriting; near-field electrospinning; graphene oxide; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Abstract : There has been an explosive interest in 2D- and 3D-printing production methods during the past decade due to the ability to rapidly create almost arbitrary structures. Challenges of printing control are encountered for instance when pushing the methods to produce smaller and smaller structures. READ MORE

5. 23. Functionalization and Characterization of Carbon Based Nanomaterials for Electronics, Composite and Biomedical Applications

   Author : Nan Wang; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; carbon nanomaterials; flexible electronics; hybrid nanowires; functionalization; graphene;

   Abstract : Surface functionalization of nanomaterials to combine different material’s properties together opens up unlimited possibilities for both academic research and industrial applications. In this thesis, flexible and scalable chemical approaches to functionalize carbon nanomaterials (CNMs) are developed for different applications, including electronics, composite and biomedical applications.

6. 24. Paper-based Supercapacitors

   Author : Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

   Abstract : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. READ MORE

7. 25. Density Functional Theory Studies of Small Supported Gold Clusters and Related Questions : What a Difference an Atom Makes

   Author : Martin Amft; Natalia Skorodumova; Olle Eriksson; Hannu Häkkinen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold clusters; CO oxidation; graphene; spin-orbit coupling; van der Waals interactions; thermally excited vibrations; Condensed matter physics; Kondenserade materiens fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : During the last decades the specific manipulation of matter on the (sub-) nanometer scale, also known as nanoscience, became possible by technologies such as the scanning tunneling microscope. Nanocatalysts, i.e. catalytic active structures of up to a few nanometers in size, belong to this rather new class of materials. READ MORE
