  1. 1. Bimetallic Palladium Catalysts for Methane Combustion in Gas Turbines

    Författare :Katarina Persson; Sven Järås; Jon McCarty; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activity; bimetal; catalytic combustion; DRIFTS; EDS; gas turbine; methane; morphology; palladium; platinum; pressure; PXRD; stability; TEM; TPO; XPS; Chemical engineering; Kemiteknik;

    Sammanfattning : Catalytic combustion is a promising combustion technology for gas turbines, which results in ultra low emission levels of nitrogen oxides (NOx), carbon monoxide (CO) and unburned hydrocarbons (UHC). Due to the low temperature achieved in catalytic combustion almost no thermal NOx is formed. LÄS MER

  3. 2. Nucleic Acids as Drug Targets - Influence of Platinum Complexes on Duplex Stability and Binding Kinetics

    Författare :Christopher Polonyi; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anticancer drugs; platinum complexes; cisplatin; oxaliplatin; nucleic acid; RNA; DNA; duplex melting; thermodynamic stability; kinetics; non-coding RNA; miRNA; siRNA; wobble base pair; loop; BRCA1; mimic; luciferase assay;

    Sammanfattning : Gaining a detailed understanding of how human cells are affected by metal-based drugs is crucial, since these drugs have shown great potential in cancer treatment. Cisplatin is used to treat many different types of cancer, e.g. testicular, ovarian, melanoma, bladder, non-small cell lung cancer, small cell lung cancer, myelomas and lymphomas. LÄS MER

  4. 3. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

    Författare :Magali Ferrandon; KTH; []
    Nyckelord :wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

    Sammanfattning : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. LÄS MER

  5. 4. PEPPSI-type Complexes of Palladium and Platinum: : Investigation of Properties and Applications in Catalysis

    Författare :Ekaterina Bolbat; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEPPSY-type complexes; palladium; platinum; C−H activation; supported homogeneous catalysts;

    Sammanfattning : Catalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate. Special compounds used forthis purpose are called catalysts; they induce a change in the chemicalenvironment without being consumed during the process. LÄS MER

  7. 5. 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.
