  1. 21. On the stability of proteins from hyperthermophiles : a structural and thermodynamic study

    Författare :Stefan Knapp; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Protein stability; hyperthermophiles; X-ray crystallography; glutamate dehydrogenase; Sso7d.;

    Sammanfattning : In this study the structural and thermodynamic basis of the thermal stability of proteins has been studied using proteins from hyperthermophilic organisms as model systems. A new type of chaperonin (TF55) has been isolated from the hyperthermophilic archaeon Sulfolobus solfataricus consisting of two different subunits named TF55-alpha and TF55-beta. LÄS MER

    Sammanfattning : Rare earth elements (REE) are a group of elements that are of critical importance in numerous technological applications, including “green technologies” such as wind turbines and hybrid car batteries. When the criticality of applications is considered, problems in supply has brought the option of effective secondary resource utilization into consideration. LÄS MER

  4. 23. Flexible inorganic and hybrid thermoelectric thin films based on layered calcium cobaltate

    Författare :Binbin Xin; Per Eklund; Biplab Paul; Niclas Solin; Jiri Houska; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetron sputtering; Nanoporous Ca3Co4O9; Thermoelectric; Flexibility;

    Sammanfattning : With the development of wearable and miniaturized electronics, self-sustaining energy sources have drawn extensive attention. Flexible thermoelectric materials and devices is an approach to convert waste heat into electricity as continuous power supply for such applications. LÄS MER

  5. 24. Expression of a lipase in prokaryote and eukaryote host systems allowing engineering

    Författare :Marianne Wittrup Larsen; Karl Hult; Marina Lotti; KTH; []
    Nyckelord :pseudozzyma candida antarctica lipase B; escherichia coli; pichia pastoris; rational design;

    Sammanfattning : Pseudozyma (Candida) antarctica lipase B (PalB) was expressed in Escherichia coli facilitating protein engineering. The lack of glycosylation was evaluated for a deeper understanding of the difficulties in expressing PalB in E. coli. LÄS MER

  7. 25. Heat and Mass Transfer Investigations of Relevance for Food Engineering Applications

    Författare :Dirk Sterner; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; mathematical modelling; frozen and non-frozen food; minced beef patties; cooking; heat and mass transfer; plate heat exchangers; evaporation;

    Sammanfattning : This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.
