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

    Author : Yvonne Nygren; Erik Björn; Knut Irgum; Bente Gammelgaard; Umeå universitet; []
    Keywords : 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;

    Abstract : 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.

  4. 12. Transition metal dissolution from Li-ion battery cathodes

    Author : Yonas Tesfamhret; Reza Younesi; Erik J. Berg; Mark Huijben; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; Lithium-ion cathode; Transition metal dissolution; Atomic Layer Deposition; Inductively coupled plasma atomic emission spectroscopy; Cathode-electrolyte interaction; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Lithium-ion batteries (LIBs) have become reliable electrochemical energy storage systems due to their relative high energy and power density, in comparison to alternative battery chemistries. The energy density of current LIBs is limited by the average operating voltage and capacity of oxide-based cathode materials containing a variety of transition metals (TM). READ MORE

  5. 13. Coupled Liquid Separation and Spectrometric Detection of Organic Compounds Containing Hetero-atoms

    Author : Eva Nilsson; Jean Pettersson; Karin Markides; Joanna Szpunar; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis exemplifies the strength in the combination of inductively coupled plasma (ICP) spectrometry and electrospray ionization tandem mass spectrometry ESI-MS/MS as detection techniques for liquid chromatography (LC) in the search for and investigation of compounds that bind or can bind hetero-atoms. Furthermore, some aspects involved in the coupling of LC and ICP spectrometry and quantification without identical standards have been studied. READ MORE

  6. 14. On the reliability of methods for the speciation of mercury based on chromatographic separation coupled to atomic spectrometric detection

    Author : Johanna Qvarnström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Mercury; speciation; hyphenated techniques; HPLC; CE; GC; CV-AAS; ICP-MS; species-specific enriched stable isotope; Analytisk kemi; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : This thesis deals with the reliability of methods for the speciation of mercury in environmental and biological samples. Problems with speciation methods that couple chromatography to atomic spectrometric detection and how to overcome the problems are discussed. READ MORE

  7. 15. Fabrication and Charaterisation of Photonic Integrated Circuits

    Author : Harendra Fernando; KTH; []
    Keywords : Plasma Enhanced Chemical Vapour Deposition PECVD ; Reactive Ion Etching RIE ; Photosensitivity; Bragg-gratings; Optical Add-drop De Multiplexsers;

    Abstract : The past few decades have seen an explosive increase ininformation transfer, fuelled by the enormous growth of theInternet, telecommunication applications, and mass mediasystems in general. Because of the very high bandwidthpotential promised by optical fibre communication technology,the area of all-optical networking has received a great amountof attention. READ MORE
