  1. 16. Determination and control of some pollutants in indoor environments

    Author : Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

    Abstract : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. READ MORE

  2. 17. Electric DNA arrays for determination of pathogenic Bacillus cereus

    Author : Yanling Liu; Sven-Olof Enfors; Helena Anderson; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacillus cereus; haemolysin; non-haemolytic enterotoxin; cytotoxin K-2; cereulide; toxin-coding genes; bacterial colony; electric DNA chip; ultrasonication; DNA fragmentation; Biochemistry; Biokemi;

    Abstract : Silicon-based electric chip arrays were developed for characterization of Bacillus cereus with respect to the capacity to produce toxins involved in food poisoning and foodborne infections. Bacteria of the B. cereus group contain different sets of four toxins encoded by eight genes. READ MORE

  3. 18. Structural study of zeolites utilizing novel electron crystallographic methods : A voyage into the world of zeolite structures

    Author : Tom Willhammar; Xiaodong Zou; Raul Lobo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; zeolites; structure determination; disorder; electron microscopy; Structural Chemistry; strukturkemi;

    Abstract : Electron crystallography has evolved as a powerful method for structural characterization of a wide range of materials. It has two significant advantages over other methods for structure determination, e.g. X-ray diffraction. READ MORE

  4. 19. Surface reactivity of metal nanoparticles : - importance of surface active agents and biomolecules from a transformation, mobility and toxicity perspective

    Author : Sara Skoglund; Inger Odnevall Wallinder; Lars Österlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal nanoparticles; surfactants; metal release; characterization; size distribution; nanotoxicology; risk assessment; Kemi; Chemistry;

    Abstract : Metallic nanoparticles possess unique properties due to their size and are widely used in e.g. consumer products. From this follows a need to identify and assess potential risks of human and environmental exposure. READ MORE

  5. 20. New Cu-I cluster compounds with luminescent properties

    Author : Ehsan Jalilian; Sven Lidin; Torbjörn Gustafsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Copper I iodide; structure determination; luminescence; TDDFT; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

    Abstract : The aim of this thesis has been to investigate how the synthesis route, choice of solvent and counter-ions effects the crystallization of Cu(I)I systems, and to investigate the correlation between the structure and luminescence properties of the systems. In order to do so a series of compounds based on an anion containing Cu(I)I, stabilized by organic cations have been produced. READ MORE
