2. 1. Structured Nanoporous Materials for Biogas Upgrading

   Author : Kritika Narang Landström; Farid Akhtar; Andreas Kaiser; George Shimizu; Marta-Lena Antti; Manuel Moliner Marín; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoporous materials; biogas upgrading; zeolites; metal-organic framework; carbon capture; separation kinetics; Engineering Materials; Materialteknik;

   Abstract : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

   Abstract : In this thesis, the studies of native and anodic oxides on both aluminum model single crystal surfaces as well as on aluminum alloys found in applications are presented. The focus has been on the characterization in situ as the oxide is growing by an electrochemical process called anodization. READ MORE

5. 3. Nanocomposites made from nanoporous cellulose fibre

   Author : Anna Svensson; Lars Wågberg; Eva Malmström Jonsson; Gunnar Westman; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis explores how to use the dry nanoporous structure of cellulosic fibres in new types of composite materials. A large effort was also given on how to correctly characterize the structure of fibres where the wet structure has been preserved also in the dry state. READ MORE
