2. 1. Metal Oxide Thin Films and Nanostructures Made by ALD

   Author : Mårten Rooth; Anders Hårsta; Jan-Otto Carlsson; Lauri Niinisö; Uppsala universitet; []
   Keywords : Inorganic chemistry; Atomic layer deposition; Metal oxide; Nanostructures; Template deposition; Thin films; Oorganisk kemi;

   Abstract : Thin films of cobalt oxide, iron oxide and niobium oxide, and nanostructured thin films of iron oxide, titanium oxide and multilayered iron oxide/titanium oxide have been deposited by Atomic Layer Deposition (ALD). The metal oxides were grown using the precursor combinations CoI2/O2, Fe(Cp)2/O2, NbI5/O2 and TiI4/H2O. READ MORE

4. 2. Template-Based fabrication of Nanostructured Materials

   Author : Anders Johansson; Mats Boman; Kornelius Nielsch; Uppsala universitet; []
   Keywords : Inorganic chemistry; Nanoparticles; nanotubes; anodic aluminium oxide; electroless deposition; ALD; Nb2O5; Prussian blue; palladium; copper; ion beam lithography; TiO2; SiO2; Oorganisk kemi;

   Abstract : Materials prepared on the nanoscale often exhibit many different properties compared to the same materials in their bulk-state. Interest in nanostructured materials has increased because of these properties in fields such as microelectronics, catalysis, optics and sensors. READ MORE

5. 3. In-situ Studies of Spontaneous Potential Oscillations during Electrochemical Deposition of Copper and Cuprous Oxide

   Author : Sofia Leopold; Jay Switzer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Spontaneous potential oscillations; electrochemical deposition; in-situ pH measurement; in-situ confocal Raman measurement; copper and cuprous oxide; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Self-oscillating behaviour in alkaline Cu(II)-lactate and -tartrate systems has been investigated by in-situ pH and confocal Raman spectroscopy measurements. Formation of Cu(II)-lactate and -tartrate complexes is a key factor underlying the self-oscillations. READ MORE

6. 4. In situ observations of tin deposition into nanoporous anodic aluminium oxide

   Author : Weronica Linpe; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; XRD; XRF; GTSAXS; XANES; Synkrotronljus; Elektrokemisk deposition; Anodisering; Tinn; Aluminiumoxid; Porös aluminiumoxid; In situ; XRD; XRF; GTSAXS; XANES; Synchrotron radiation; Electochemical deposition; Anodisation; Sn; Native aluminium oxide; Porous aluminium oxide; Nanoporous anodic aluminium oxide; In situ;

   Abstract : AbstractIn this thesis, the electrochemical deposition process of Sn into ordered nanoporous anodic aluminium oxide (NP-AAO) have been studied. The deposition process was studied in situ using the X-ray techniques: X-ray diffraction (XRD), Grazing incidence Transmission Small-Angle X-ray Scattering (GTSAXS), X-ray Fluorescence (XRF) and X-ray Absorption Near Edge Structure (XANES) and ex situ using Focused Ion Beam-Scanning Electron Microscopy and Transmission Electron Microscopy measurements.

7. 5. Development of syntheses for nanostructured titania and silica

   Author : Gunnar Örn Simonarson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium intercalation; nanoparticles; X-ray characterization; mesoporous silica; mesoporous titania; spray deposition; Titanium dioxide;

   Abstract : Nanostructured titania is of great interest for a variety of energy and environmental applications, including conversion of solar energy, for energy storage systems and removal of organic pollutants in water and air. Titania is composed of earth abundant elements, it is environmentally friendly and chemically stable which makes it an attractive material to utilize. READ MORE
