3. 2. Towards Solution Processed Electronic Circuits Using Carbon Nanotubes

   Författare :Zhiying Liu; Shili Zhang; Adrian Lonescu; Uppsala universitet; []
   Nyckelord :;

   Sammanfattning : Emerging macro- and flexible electronic applications such as foldable displays, artificial skins, and smart textiles grow rapidly into the market. Solution-processed thin-film transistors (TFTs) based on single-walled carbon nanotubes (SWCNTs) as the semiconductor channel can offer high performance, low cost and versatility for macro- and flexible electronics.

4. 3. Advanced Organic Hole Transport Materials for Solution-Processed Photovoltaic Devices

   Författare :Xu Bo; Sun Licheng; Karl Leo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

   Sammanfattning : Solution-processable photovoltaic devices (PVs), such as perovskite solar cells (PSCs) and solid-state dye-sensitized solar cells (sDSCs) show great potential to replace the conventional silicon-based solar cells for achieving low-cost and large-area solar electrical energy generation in the near future, due to their easy manufacture and high efficiency. Organic hole transport materials (HTMs) play important roles in both PSCs and sDSCs, and thereby can well facilitate the hole separation and transportation, for obtaining high performance solar cells.

7. 5. Carbothermal synthesis of nano-structured metal, carbides and nitrides, using solution processed precursors; from precursor to product

   Författare :Sarmad Naim Katea; Gunnar Westin; Hilmar Vidarsson; Sanjay Mathur; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solution-based chemical processing; sol-gel; ceramic powders; transition metal carbides and nitrides; sintering; nickel binder; mechanical properties; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : This thesis describes how solution chemical based carbothermal syntheses can be used for the synthesis of nanostructured zirconium carbide and nitride nanophase powders as well as a nickel-metal coating on NbC for use as a sintering agent. The focus is on the development of novel synthesis routes using atomic or small nanoscale level mixing of the metal oxide and carbon source in the starting precursors, enabling the use of lower synthesis temperatures and non-agglomerated nanosized powders.
