   Abstract : This thesis is a summary and discussion of eight papers dealing with failures and structural aspects of Ni-Cd industrial pocket plate batteries, applications of voltammetry in adsorption studies on goethite (a-FeOOH) surfaces and synthesis and characterisation of nanostructured carbons. The work consists of different areas of chemistry; electrochemistry, structural chemistry and solution chemistry. READ MORE

4. 2. Development of electrochemical sensor and biosensor platforms : detection of therapeutic drugs and heavy metal ions

   Author : Sereilakhena Phal; Solomon Tesfalidet; Britta Lindholm-Sethson; William Siljebo; Pankaj Vadgama; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sensors; electrode surface modification; electrochemical immitance spectroscopy; square wave anodic stripping voltammetry; singular value decomposition; therapeutic drugs; heavy metals;

   Abstract : Electrochemical sensors and biosensors combine the sensitivity of electroanalytical methods with the selectivity of a sensor or biosensor surface. The chemical or biochemical component (receptor) in the sensor recognizes an analyte and produces an electrical signal which is proportional to the analyte concentration. READ MORE

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

   Author : Kequan Xu; Gaston A. Crespo; Maria Cuartero; Tom Lindfors; KTH; []
   Keywords : 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;

   Abstract : 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.

6. 4. Electrochemical Application and AFM Characterization of Nanocomposites : Focus on Interphase Properties

   Author : Hui Huang; Per Claesson; Orlando Rojas; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrochemical sensor; nanocomposite; graphene; carbon nanotubes; phytic acid; polyaniline; corrosion protection; silica nanoparticles; atomic force microscopy; interphase; Kemi; Chemistry;

   Abstract : The use of graphene and conductive polyaniline nanomaterials in the field of electrochemistry is increasing due to their excellent conductivity, rapid electron transfer and high specific surface area. However, these properties are strongly dependent on the preparation processes. READ MORE

7. 5. The cross-talk of iron and ascorbate -Complexation and intracellular regulation of transport in human enterocytes

   Author : Nathalie Scheers; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NRAMP2; ascorbate; ferroportin; ferritin; iron; SVCT1; DCYTB;

   Abstract : Iron deficiency is a serious health issue in developing countries and also in vulnerable groups of the industrialized world. There are several ways to address this issue. The present approach was to learn more about the basic mechanisms of iron uptake in the presence of ascorbate, one of the best enhancers of iron absorption. READ MORE
