1. 1. Microextraction for usage in environmental monitoring and modelling of nitroaromatic compounds and haloanisoles

   Författare :Sofie Jönsson; Bert van Bavel; Tomas Öberg; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCA; PLS; QSPR; SPME; MEPS; nitroaromatic compounds; TCA; TBA; Chemistry; Kemi; Kemi; Chemistry;

   Sammanfattning : Processes in the environment are often complex and the description and prediction of the behaviour of environmental pollutants requires sophisticated methodology including multidimensional technology. Multivariate statistical methods including principal component analysis (PCA) and partial least squares projection to latent structures (PLS) were used to characterise several nitroaromatic compounds according to a large number of chemical and physical properties.

3. 2. Ethers as gasoline additives : toxicokinetics and acute effects in humans

   Författare :Annsofi Nihlén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :acute effects; biological monitoring; ethyl tertiary-butyl ether; ETBE; man; methyl tertiary-butyl ether; MTBE; oxygenate; petrol; physiologically based toxicokinetic model; PBTK; PBPK; tertiary-butyl alcohol; TBA; toxicokinetics;

   Sammanfattning : Ethers or other oxygen-containing compounds are used as replacements for lead in gasoline and to ensure complete combustion. Methyl tertiary-butyl ether (MTBE) is already in use world-wide and ethyl tertiary-butyl ether (ETBE) may be used increasingly in the future. LÄS MER

4. 3. Upgrading Cellulose Networks: Conquering Limitations in Fiber Foams

   Författare :Eliott Jean Quentin Orzan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross-linking; pore structure; cellular solid; lightweight; porous network; cellulose; flame-retardancy; fibers;

   Sammanfattning : The battle to create structural materials with low environmental impact demands the investiture of two champions: porous structures and cellulose substrates. The dominant solutions when constructing strong lightweight materials are plastic and metallic foams, while currently, cellulose fiber foams suffer from challenges which hamper their development.

   Sammanfattning : Aqueous solutions were studied using photoelectron and Auger spectroscopy, based on synchrotron radiation and a liquid micro-jet setup. By varying the photon energy in photoelectron spectra, we depth profiled an aqueous tetrabutylammonium iodide (TBAI) solution. LÄS MER

7. 5. Correlation Functions in Integrable Theories : From weak to strong coupling

   Författare :Raul Pereira; Joseph Minahan; Sergey Frolov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superstring theory; AdS CFT correspondence; Integrable field theories; Hexagon form factors; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : The discovery of integrability in planar N=4 super Yang-Mills and ABJM has enabled a precise study of AdS/CFT. In the past decade integrability has been successfully applied to the spectrum of anomalous dimensions, which can now be obtained at any value of the coupling. LÄS MER
