   Sammanfattning : This thesis summarizes a study on the pressure-induced amorphization (PIA) and structures of amorphous states of clathrate hydrates (CHs).PIA involves the transition of a crystalline material into an amorphous solid in response of mechanical compression at temperatures well below the melting point.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetylide carbides; high pressure; Raman spectroscopy; powder X-ray diffraction; Rietveld refinement; Materials Chemistry; materialkemi;

   Sammanfattning : Alkali (A) and alkaline earth (AE) metals can form carbides and intercalated graphites with carbon. The carbides mostly represent acetylides which are salt-like compounds composed of C22− dumbbell anions and metal cations. Both the acetylide carbides and intercalated graphites are technologically important. LÄS MER
