3. 2. Computational studies on 2D and 3D amorphous solids : Investigation of structure-property relationship

   Författare :Emel Gürbüz; Biplab Sanyal; Andreas Larsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amorphous solids; Metallic glasses; Classical molecular dynamics simulations; Thermal transport; Density functional theory; 2D glasses; Vibrational properties; Magnetism; Optical properties;

   Sammanfattning : Amorphous materials represent a large and diverse family, with many questions still remaining unanswered regarding their structure-property relationship. The structural complexity of these materials poses challenges for simulations in contrast to crystalline materials where density func­tional theory (DFT) can be used easily by exploiting the translation symmetry.

4. 3. ZnO Quantum Dots : Size Dependent Optical, Vibrational and Photoelectrochemical Properties

   Författare :Jesper Jacobsson; Tomas Edvinsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ZnO; nanoparticels; quantum dots; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Sammanfattning : This thesis is devoted to quantum dots of ZnO in the size regime 2.5-10 nm.The focus is directed towards their size dependent properties with specialemphasis on the optical, vibrational and photocatalytic properties. The particleswere synthesized by hydrolysis in alkaline zinc acetate solution. LÄS MER

5. 4. Vibrations in timber floors : Dynamic properties and human perception

   Författare :Kirsi Jarnerö; Anders Professor; Tomi Toratti; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden floor; timber floor; vibration; design criteria; damping; frequency; questionnaire; field test; socio-vibrational survey; vibration annoyance; vibration disturbance; Byggteknik; Civil engineering;

   Sammanfattning : Springiness and vibrations of timber floors are familiar to many as a ‘live’ feelwhen walking on them, especially if living in single family housing with timberframework. Since the building regulations in Sweden changed to performancedependentrequirements in 1994 the use of timber in multifamily housing hasincreased. LÄS MER

7. 5. Transition Metal Hydride Complexes and Hydrogenated Gallium Clusters : Synthesis and Structural Properties

   Författare :Henrik Fahlquist; Dag Noréus; Maximilian Fichtner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal hydrides; Solid state Synthesis; X-ray diffraction; Neutron Scattering; strukturkemi; Structural Chemistry;

   Sammanfattning : Synthesis and structural characterisation of metal hydrides in two important systems are presented. The first system presented is low valent cobalt and nickel complex hydrides with the compositions BaMg5Co2H10, RbMg5CoNiH10, SrMg2CoH7and Sr4Mg4Co3H19 featuring nickel with oxidation state of 0 and cobalt with oxidation state +I and -I.
