    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reaction crystallization; benzoic acid; nucleation; growth; kinetics; growth rate dispersion; Chemical physics; Kemisk fysik;

    Sammanfattning : This thesis aims at increasing the fundamental understanding of reaction crystallization by modeling, simulations and parameter estimation. Benzoic acid is used as the model compound. LÄS MER

  3. 7. Isolation, Synthesis and Structure-Activity Relationships of Antifeedants against the Pine Weevil, Hylobius Abietis

    Författare :Carina Eriksson; Christina Moberg; John Pickett; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pine weevil; Hylobius abietis; semiochemicals; antifeedant; feeding deterrent; feeding stimulant; bark extract; carboxylic acid; piperidine alkaloids; structure-activity; cinnamic aldehyde; benzaldehyde; Organic chemistry; Organisk kemi;

    Sammanfattning : The large pine weevil, Hylobius abietis L., is a major insect pest on conifer seedlings in northern Europe. Due to its feeding newly planted trees get girdled, resulting in high seedling mortality (up to 80%). As a consequence great financial losses to the forest industry occur. LÄS MER

  4. 8. Aqueous Solutions as seen through an Electron Spectrometer : Surface Structure, Hydration Motifs and Ultrafast Charge Delocalization Dynamics

    Författare :Niklas Ottosson; Svante Svensson; Olle Björneholm; Gunnar Öhrwall; Clemens Heske; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water; Aqueous solutions; Ions; Molecular Hydration; Electron dynamics; Atmospheric Chemistry; Hydrolysis; Acid-Base Chemistry; Interatomic Coulombic Decay; ICD; Liquid Micro-Jet; X-ray Photoelectron Spectroscopy; XPS; Auger Electron Spectroscopy; AES; MAX-lab; BESSY; Physics; Fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.

  5. 9. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

    Författare :Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. LÄS MER

  7. 10. Glycolytic flux regulation in Saccharomyces cerevisiae during anaerobic growth and starvation

    Författare :Elisabeth Thomsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces; Yeast; Starvation; Energetics; Chemostat; Anaerobic;

    Sammanfattning : The physiology of S. cerevisiae under anaerobic growth conditions is of interest not least during implementation and development of industrial yeast-catalysed ethanol fermentations in order to maintain a productive yeast population. LÄS MER
