1. 6. Tunable surfaces : using polyoxoniobates and -tantalates as molecular building blocks

   Författare :Mark Rambaran; C. André Ohlin; Jean-Francois Boily; Mari-Ann Einarsrud; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis describes and explains the use of aqueous polyoxometalates (POMs), as molecular building blocks in the fabrication of tunable solid-state materials, such as thin films.  Microwave irradiation in the synthesis of Nb10, Nb6 and Ta6 is a rapid and efficient alternative to conventional hydrothermal methods, while offering equal – if not greater yields – of product.

3. 7. Ab initio based modeling of defects and disorder in industrial materials

   Författare :Yunguo Li; Pavel Korzhavyi; Tony Paxton; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : The study of defects and disorder in condensed matter remains a central subject of materials science. Newly emerging experimental and theoretical techniques promote our understanding in this field, and reveal many interesting phenomena in which the atomic picture plays a crucial role. LÄS MER
