3. 2. Porous Amorphous Calcium Carbonate and Phosphate : Synthesis and Application

   Författare :Rui Sun; Ocean Cheung; Maria Strømme; Ken Welch; Denis Gebauer; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous calcium carbonate; amorphous calcium phosphate; stabilization; crystallization; porous material; drug delivery; gas adsorption; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Sammanfattning : The synthesis of porous amorphous calcium carbonate (ACC) and porous amorphous calcium phosphate (ACP) was developed in this thesis. Porous ACC with specific Brunauer–Emmett–Teller (BET) surface area of >350 m2/g was synthesized using a surfactant free approach. The high surface area of porous ACC was related to its nanostructure. LÄS MER
