1. 1. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation

   Författare :Rui-Tao Wen; Claes-Göran Granqvist; Agustín R. González-Elipe; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromic; smart windows; long-term durability; degradation kinetics; ion trapping; de-trapping; materials rejuvenation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. LÄS MER

3. 2. Durability and Long-term Performance of Adhesively Bonded FRP/steel Joints

   Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRP steel joints; durability; fibre reinforced polymer; cohesive zone modelling; long-term performance; adhesively bonded joints; moisture diffusion;

   Sammanfattning : Fibre reinforced polymer (FRP) composites offer excellent properties, such as high specific strength and stiffness, corrosion resistance and light weight. Over the past four decades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER

5. 4. Durability of Cementitious Materials in Long-Term Contact with Water

   Författare :Arezou Babaahmadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Nuclear electricity is considered to be an alternative energy production solution for the power industry in many countries. To ensure the sustainability of this energy solution, the disposal of the produced waste is one of the biggest issues facing nuclear electricity industries. LÄS MER

7. 5. Durability of District Heating Pipes

   Författare :Stefan Forsaeus Nilsson; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reuse of excavated material; district heating pipe; moisture diffusion; pipe joint; stone indentation; polyurethane foam; polyethylene; district heat distribution; long-term strength; buried pipe;

   Sammanfattning : This thesis is focused on mechanical loads and moisture related problems with a potential to critically harm the functionality of pre-insulated district heating pipes and pipe joints. Directly buried pipeline bends are investigated with respect to limiting deformations from a thermally induced lateral displacement. LÄS MER
