  2. 21. Amine transaminase: Process development aspects for chiral amine synthesis

    Author : Tim Börner; Bioteknik; []
    Keywords : ;

    Abstract : Many modern drugs contain chiral amine moieties and the need for more efficient processes to synthesize these amines in high optical purity and concentration are greatly demanded by the fine chemical and pharma industry. Amine transaminases (ATA) allow for the direct asymmetric synthesis of optically pure amines from ketone substrates. READ MORE

  4. 22. High Resolution Microanalysis of Creep Resistant 9-12% Chromium Steels

    Author : Lars Lundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; martensitic stainless steel; TEM; modified 12% chromium steel; creep resistant; atom-probe field-ion microscopy;

    Abstract : This thesis deals with detailed studies of the microstructure of 9-12% chromium steels. Three alloys with improved creep resistance have been studied in different stages of heat treatment and after creep testing. Two of them were manufactured using PM/HIP and were of the type 10.

  5. 23. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass

    Author : Hanbing He; Marcus Öhman; Kent Davidsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layer formation; bed particle; woody biomass; quartz; K-feldspar; olivine; bed agglomeration; deposition; fluidized bed; combustion; gasification; Energiteknik; Energy Engineering;

    Abstract : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. READ MORE

  6. 24. Defect Thermodynamics and Kinetics in Polyanionic Cathodes : A Theoretical Roadmap for Na-ion based Batteries and Hybrid Supercapacitors

    Author : Teeraphat Watcharatharapong; Rajeev Ahuja; Sudip Chakraborty; Jan Isberg; Palani Balaya; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT; Energy Materials; Defects; Chemical potentials; Kinetics; Hybrid supercapacitors; Na-ion batteries; Polyanionic cathodes;

    Abstract : In this thesis, the framework of the density functional theory is employed to study and predict properties of polyanionic cathodes for Na-ion batteries and hybrid supercapacitors. It consists of three main parts as follows:The first part is primarily dedicated to kröhnkite-type Na2Fe(SO4)22H2O cathode. READ MORE

  7. 25. The fate and ash transformations of phosphorus in combustion of biomass and sewage sludge

    Author : Joel Falk; Marcus Öhman; Nils Skoglund; Dan Boström; Franz Winter; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The combustion of phosphorus (P)-rich biomass has a significant potential to increase the stock of biomass resources available for renewable heat and power production. In addition, the P-rich ashes have the potential as a fertilizer and could reduce the need for non-renewable P resources in agriculture. READ MORE
