  2. 1. Photocatalysis for Indoor Air Cleaning : In situ FTIR and DFT Study of Acetaldehyde Photo-Oxidation on TiO2 and Sulfate-Modified TiO2

    Author : Bozhidar Stefanov; Lars Österlund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; acetaldehyde; crotonaldehyde; dimer; adsorption; DFT; FTIR; photocatalysis; micro-kinetic modeling; acid–base properties; surface functionalization; Solid State Physics; Fasta tillståndets fysik; Materialvetenskap; Materials Science;

    Abstract : Acetaldehyde is among the group of VOC’s causing the so-called "sick building" syndrome. WHO has estimated that this problem, related to the indoor air-quality, affects one third of all buildings worldwide. TiO2 is an attractive material for the photocatalytic removal of VOC’s in the indoor environment. READ MORE

  4. 2. Experimental studies on acute health effects of acrolein and other aldehydes

    Author : Aishwarya Mishra Dwivedi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Aldehydes are reactive and ubiquitous in indoor as well as outdoors and can give rise to significant health problems in humans, e.g. irritation of the eyes and toxic effects on the upper respiratory tract. This thesis focuses on the irritating and inflammatory properties of three commonly occurring aldehydes; acrolein, crotonaldehyde and hexanal. READ MORE

  5. 3. Investigations of selectivity control in catalysis

    Author : Henrik von Schenck; KTH; []
    Keywords : ;

    Abstract : Catalytic reactions are ever present in applied chemistry,from laboratory synthesis to industrial scale processes.Catalysts provide the means to influence both the rate ofreactions (activity) and the product outcome (selectivity),thereby having fundamental impact on the reaction efficiency.

  6. 4. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness

    Author : Anders Nilsson; Christer Tagesson; Verner Lagesson; Göran Strid; Linköpings universitet; []
    Keywords : acrylates adverse effects; air pollution; ultraviolet; indoor analysis; chromatography; gas; environmental exposure adverse effects; sick building syndrome etiology; dust; volatilization; Spectrophotometry; MEDICINE; MEDICIN;

    Abstract : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. READ MORE

  7. 5. 32P-postlabelling analysis of complex DNA adducts in human tissues

    Author : Ke Yang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Complex DNA adducts in humans originate from exogenous and endogenous sources. Polycyclic aromatic hydrocarbons (PAHs) are a large group of chemicals including many potent carcinogens. PAHs are ubiquitously present in the environment and PAH-DNA adducts have been extensively studied in humans. READ MORE
