2. 1. Nanotubes for Battery Applications

   Author : Sara Nordlinder; Kristina Edström; Torbjörn Gustafsson; M. Stanley Whittingham; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; vanadium oxide; nanotubes; lithium battery; Li-ion battery; XRD; PES; electrochemistry; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Abstract : Nanomaterials have attracted great interest in recent years, and are now also being considered for battery applications. Reducing the particle size of some electrode materials can increase battery performance considerably, especially with regard to capacity, power and rate capability. READ MORE

4. 2. Electrochemical characterisations of TiO2 nanotube and lithium-metal electrodes for lithium-based batteries

   Author : Charlotte Ihrfors; Leif Nyholm; Fredrik Björefors; Marnix Wagemaker; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; titanium dioxide nanotubes; lithium metal electrodes; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Abstract : Lithium-ion batteries have since their introduction on the commercial market in the early 1990s played an important role within the field of energy storage. In this thesis both titanium dioxide, TiO2, and lithium metal are investigated based on their properties as anodes for lithium-based battery technologies. TiO2 nanotubes with lengths between 4.

5. 3. Structural, thermal and thermodynamic properties of some Ln-Pd oxides and their behaviour as catalyst precursors

   Author : Martin Andersson; A.R. West; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

   Abstract : The structural, thermal and thermodynamic properties of some Ln-Pd oxides of the Ln4Pd07 type are presented. The main results are; (i) Reduction of Ln4Pd07, either ex-situ by CO or in-situ by a synthetic car exhaust gas, results in a materialwith catalytic activity for car exhaust gas clean-up reactions.

6. 4. Novel bioinspired and biohybrid electrode materials for hydrogen production

   Author : Afridi Zamader; Gustav Berggren; Vincent Artero; Marc Robert; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Device; H2; [FeFe] hydrogenases; inspiration; catalyst; multiwalled carbon nanotubes; life cycle assesments; semisynthetic hydrogenases; Kemi; Chemistry; Biokemi; Biochemistry;

   Abstract : This thesis was accomplished under the scope of eSCALED project administrated by EU MSCA horizon 2020 program, which aimed to develop a device called “artificial leaf” responsible for generating fuels or liquid chemicals (H2 production or CO2 reduction) using solar electrolysis. My objective was to develop a noble metal free, efficient cathode materials for H2 production for the device which yield this thesis. READ MORE

7. 5. 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
