2. 1. Toxicity and biological impact of metal and metal oxide nanoparticles : Focus on the vascular toxicity of ultra-small titanium dioxide nanoparticles

   Author : Narges Bayat; Susana Cristobal; Janeck James Scott-Fordsmand; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Nanotoxicology; Ultra-small nanoparticles; Biochemistry; biokemi;

   Abstract : The application of nanoparticles (NPs) in different technologies has led to tremendous advancement in those fields.  Moreover, there is growing interest in application of ultra-small NPs (USNPs) at 1-3 nm due to their distinct molecule like features. Parallel to these promises, there is a growing concern regarding their safety. READ MORE

4. 2. Hydrolytic Synthesis and Physicochemical Properties of TiO2 Nanoparticles: Fundamentals and Applications

   Author : Jenny Perez-Holmberg; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dioxide TiO2 ; Nanoparticles; Synthesis; Hydrolysis; Titanium tetrachloride TiCl4 ; Anatase; Brookite; DLS; ES-SMPS; XRD; Collective diffusion; Interfacial processes;

   Abstract : Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with well-defined size distributions were obtained. READ MORE

5. 3. 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

6. 4. Self-Assembling Surfactant Aggregates for Synthesis of Nanomaterials

   Author : Martin Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-assembly; Ag; photocatalysis; nanoparticles; surfactants; liquid crystals; microemulsions; rutile; mesoporous materials; CaCO3; anatase; TiO2;

   Abstract : The main objective of this thesis was to study how surfactant assemblies can be used as templates to form inorganic nanomaterials. Both water-in-oil microemulsions and liquid crystalline phases have been used as structure directing agents. READ MORE

7. 5. Atomistic simulations of structural and dynamical properties of liquids under geometric constraints

   Author : Lorenzo Agosta; Alexander Lyubartsev; Marialore Sulpizi; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; liquid; contraint; TiO2; surfaces; bio-inorganic; molecular dynamic; ab-initio; tight-binding; DFT; metadynamic; free energy; nanoparticles; water; amino acids; adsorption; mesophases; hexatic; smectic; triply periodic network; Fddd; fysikalisk kemi; Physical Chemistry;

   Abstract : The statistical-mechanical description of liquids represents a formidable problem in physic due to the absence of the analytical theory of the liquid state. Atomistic simulations represent a unique source of information in this respect and can be implemented in order address macroscopically measurable liquid properties, including its structure and dynamics, based on the information of the interactions between its constituent molecules.
