2. 1. Formation of nanoparticles by laser-activated processes

   Author : Lars Landström; Mats Boman; Peter Heszler; Joop Schoonman; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; nanoparticles; laser-assisted CVD; laser ablation; emission spectroscopy; size-distribution; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Due to the small dimensions, nanoparticles and materials consisting of nano-sized building blocks exhibit unique — mostly superior — properties, well differing from their bulk counterpart. Most of the novel properties of nanoparticles (and nanomaterials) are size-dependent, while the majority of the common gasphase methods used for generation of nanopowders result in different, usually wide, size-dispersions.

4. 2. Development of Metal–Organic Frameworks for Catalysis : Designing Functional and Porous Crystals

   Author : Fabian Carson; Xiaodong Zou; Jeffrey R. Long; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal–organic frameworks; heterogeneous catalysis; nanoparticles; metallolinkers; postsynthetic modification; postsynthetic exchange; Inorganic Chemistry; oorganisk kemi;

   Abstract : Metal–organic frameworks, or MOFs, have emerged as a new class of porous materials made by linking metal and organic units. The easy preparation, structural and functional tunability, ultrahigh porosity, and enormous surface areas of MOFs have led to them becoming one of the fastest growing fields in chemistry. READ MORE

5. 3. Structure and chemical ordering in metallic nanoparticles from atomic scale modeling

   Author : Magnus Rahm; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; regular truncated octahedron; chemical ordering; nanoparticle shapes; molecular dynamics; icosahedron; Monte Carlo; modeling; Marks decahedron; nanoparticle structures;

   Abstract : In the last decades, a wide range of attractive properties have put metallic nanoparticles in the spotlight. These properties, often related to optical response and catalytic performance, are to a large extent dependent on structure and chemical ordering, that is, the distribution of elements in the nanoparticle.

7. 5. Kinetic Measurements Using Nanoplasmonic Sensing

   Author : Markus Schwind; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

   Abstract : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. READ MORE
