  1. 21. 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.

  3. 22. Photopatternable Electrolytes for Conducting Polymer Actuators

    Författare :Yong Zhong; Edwin Jager; Anthony Turner; Jose Gabriel Martinez; Aleksandar Matic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electroactive polymers (EAPs) are materials that can change their dimensions or shape in response to electric stimulation. They have attracted considerable interests for their applications as soft, lightweight and silently operating polymer actuators. One significant group of EAPs is conducting polymers. LÄS MER

  4. 23. Voltage sensor movements in shaker and HCN channels

    Författare :Roope Männikkö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Voltage-gated ion channels are crucial for electrical signaling in living organisms. They are composed of four similar subunits with six transmembrane α-helices, S1-S6. Each subunit contains a voltage-sensing domain, S1-S4, and an ion-conducting pore domain, S5-S6. LÄS MER

  5. 24. Polyunsaturated Fatty Acids Modifying Ion Channel Voltage Gating

    Författare :Sara Börjesson; Fredrik Elinder; Klaus Benndorf; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Voltage-gated ion channels play fundamental roles in neuronal excitability and therefore dysfunctional channels can cause disease. Epilepsy is such a disease, affecting about 1% of the population and being characterized by synchronous electric activity of large groups of neurons leading to various types of seizures. LÄS MER

  7. 25. Ion Current and Torque Modeling for Combustion Engine Control

    Författare :Ingemar Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Engine control development constantly requires more information about the combustion process, to meet present and future environmental regulations for vehicles. The demand for combustion monitoring and control from enginedevelopers drives the research in several parallel fields of technology to find the best and most cost effective sensor solution for each case.
