  1. 1. Advances in analytical methodologies for studies of the platinum metallome in malignant cells exposed to cisplatin

    Författare :Yvonne Nygren; Erik Björn; Knut Irgum; Bente Gammelgaard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Method development; Metallome; Inductively coupled plasma mass spectrometry; Electrospray ionization mass spectrometry; Liquid chromatography; Hyphenation; Organic modifier; Cisplatin; Platinum; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : The scientific progress about the important chemotherapeutic drug substance cisplatin (CDDP) and its function has often been rendered by data difficult to interpret, and still many questions about its mode of action remains to be clarified by the scientific community. However, studies of CDDP possess a high complexity due to; i) low intracellular concentration, ii) many potential biomolecule targets, iii) poor or unknown stability of the intact drug and its biomolecule adducts and iv) complex and varying sample matrices.

  3. 2. Chargeand Light Management in Organic Solar Cells

    Författare :Zheng Tang; Olle Inganäs; René Janssen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Solar cells based on organic materials are extensively investigated both in academia and industry, owing to their potential of being inexpensive, lightweight, flexible and suitable for roll-to-roll production. Performance of organic solar cells has been rapidly improving, and the state of the art organic solar cells have an efficiency over 10%. LÄS MER

  4. 3. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats

    Författare :Pia Norling; Nils Kautsky; Tom Ysebaert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; blue mussel; Mytilus spp.; ecosystem engineering; habitat-modifier; diversity; facilitation; ecosystem functioning; ecosystem services and water quality maintenance; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates. These assemblages change the local environment and create unique habitats. LÄS MER

  5. 4. Atomistic simulation techniques for modelling inorganic/organic interface and flotation collector design

    Författare :Tarun Kundu; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The choice of collector molecules in flotation process of mineral separation is invariably determined by tedious trial and error experimentation with inherent mounting expenditure. Here, we seek the help of atomistic simulation techniques, to help and judge the suitable collector molecule for selective mineral separation in flotation process, before actually conducting the experiment.

  7. 5. Development of techniques and methods for drug analysis by packed capillary liquid chromatography with octadecylbonded silica and porous graphitic carbon columns

    Författare :Pernilla Koivisto; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Packed capillary liquid chromatography in combination with ultraviolet and mass spectrometric (MS) detection was explored as an analytical tool for drug analysis. The focus was put on column and sample preparation techniques as well as on fundamental aspects and development of chromatographic separations. LÄS MER
