  1. 16. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Författare :Rong Cao; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Sammanfattning : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. LÄS MER

  3. 17. First-Principles Modeling of Selected Heterogeneous Reactions Catalyzed by Noble-Metal Nanoparticles

    Författare :Xinrui Cao; Yi Luo; Peijun Hu; KTH; []
    Nyckelord :;

    Sammanfattning : Heterogeneous catalysis is an important branch in catalysis, in which the catalyst and reactants are in different physical phases. In this thesis, we have carried out extensive first-principles calculations to explore the selected heterogeneous reactions catalyzed by the noble-metal nanoparticles. LÄS MER

  4. 18. Pool Boiling on Structured Surfaces: Heat Transfer and Critical Heat Flux : Experiments and Mechanistic Modelling

    Författare :Zhen Cao; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pool boiling; heat transfer; critical heat flux; bubble dynamics; surface modification;

    Sammanfattning : In this thesis, pool boiling heat transfer was experimentally studied on structured surfaces with dielectric liquids (HFE-7200, NOVEC-649, FC-72), organic liquids (Acetone, Pentane) and deionized water.In the first step, nanoparticle coatings on copper surfaces were prepared by an electrophoretic deposition method, with Cu-Zn nanoparticles (100 nm) and Cu nanoparticles (150 nm).

  5. 19. Theoretical and experimental studies of surface and interfacial phenomena involving steel surfaces

    Författare :Weimin Cao; Seshadri Seetharaman; Oleg Ostrovski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur; Oxygen; Adsorption; Iron surface; ab initio calculations; Adsorption energy; Work function; Difference charge density; Magnetic properties; Thermodynamic stability; Average velocity; Monte Carlo simulation; X-ray sessile drop method; Mass transfer; Interfacial velocity; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The present work was initiated to investigate the surface- and interfacial phenomena for iron and slag/iron systems. The aim was to understand the mechanism of the effect of surface active elements on surface and interfacial properties. LÄS MER

  7. 20. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

    Författare :Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. LÄS MER
