  4. 4. Porous Amorphous Calcium Carbonate and Phosphate Synthesis and Application

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rui Sun; Uppsala universitet.; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE
