    Sammanfattning : The preparation of chiral molecules, i.e. compounds that are not identical to their mirror image, is of great interest in the field of organic chemistry. LÄS MER

  4. 3. Electrochemical detection of trace metals: from traditional techniques to new ultrathin membrane electrodes

    Författare :Kequan Xu; Gaston A. Crespo; Maria Cuartero; Tom Lindfors; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion-selective electrodes; ion-stripping voltammetry; ultrathin membranes; interconnected ion-transfer and charge-transfer processes; trace metals; environmental waters; jonselektiva elektroder; jon-strippande voltammetri; ultratunna membran; sammankopplade jonöverförings- och laddningsöverförings-processer; spårmetaller; miljövatten; Kemi; Chemistry;

    Sammanfattning : Accurate detection of trace metals in environmental waters is an analytical challenge that is still open for the time being. The current state of the field reveals the predominance of the so-called hanging mercury drop electrode (HMDE) for multi-metal detection by means of anodic stripping voltammetry (ASV) readout.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perovskite; Solar cells; Organic-inorganic lead halide; Dimensionality; Bandgap; X-ray diffraction; X-ray spectroscopy.; Kemi; Chemistry;

    Sammanfattning : AbstractMethylammonium lead (II) iodide has recently attracted considerable interest which may lead to substantial developments of efficient and inexpensive industrial photovoltaics. The application of this material as a light-absorbing layer in solid-state solar cells leads to impressive efficiency of over 22% in laboratory devices. LÄS MER

  7. 5. Drugs and polymers in dissolving solid dispersions : NMR imaging and spectroscopy

    Författare :Carina Dahlberg; István Furó; Anna Millqvist-Fureby; Michael Schuleit; Jadwiga Tritt-Goc; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi; PHARMACY; FARMACI;

    Sammanfattning : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.
