1. 36. Methodologies for Non-aqueous Systems and Precipitating Systems as Carbon Capture Technologies : A case-study of AMP-NMP

   Författare :Meher Sanku; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; non-aqueous; precipitating; thermodynamic model; crystallization kinetics;

   Sammanfattning : In order to combat the effects of climate change, it is important to use a combination of solutions to achieve carbon neutrality as soon as possible. Carbon capture and sequestration is one such technology that can be used to significantly reduce the carbon footprint of many industrial plants. LÄS MER

3. 37. Theoretical modeling of molar volume and thermal expansion

   Författare :Xiao-Gang Lu; Bo Sunsman; Michel Jacobs; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; first-principles calculations; ab initio; Calphad; Debye-Grüneisen model; thermodynamic properties; elastic modulus; volume; thermal expansivity; pressure; Thermo-Calc; VASP; element; carbide; nitride; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Combination of the Calphad method and theoretical calculations provides new possibilities for the study of materials science. This work is a part of the efforts within the CCT project (Centre of Computational Thermodynamics) to combine these methods to facilitate modeling and to extend the thermodynamic databases with critically assessed volume data.

4. 38. Effects of Macromolecular Crowding on Protein Folding : - in-vitro equilibrium and kinetic studies on selected model systems

   Författare :Alexander Christiansen; Pernilla Wittung-Stafshede; Thomas Kiefhaber; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein Folding; macromolecular crowding; excluded volume; spectroscopy; stopped-flow; biokemi; Biochemistry;

   Sammanfattning : Protein folding is the process during which an extended and unstructured polypeptide converts to its compact folded structure that is most often the functional state. The process has been characterized extensively in dilute buffer in-vitro during the last decades but the actual biological place for this process is the inside of living cells. LÄS MER

5. 39. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons

   Författare :Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; biomass; waste; superheater corrosion; austenitic steel; biomass gasification; alumina-forming austenitic stainless steel; thermodynamic modelling; kinetic modelling; Kemi; Chemistry;

   Sammanfattning : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

7. 40. Computer Modelling of the Interaction between Water and Complex Solid Phases

   Författare :Susanne Börjesson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOLISOL; thermodynamic model; complex solid; cement; PHREEQE; repository; PASSIPHIC; leaching; solid solution;

   Sammanfattning : In this work the program package PASSIPHIC is described. The program has been developed to calculate the equilibrium for an aqueous phase in contact with a complex solid. The complex solid is considered as consisting of pure minerals and /or solid solutions. Cement has been used as an example. LÄS MER
