  1. 1. Modelling of the electrochemial treatment of tumours

    Författare :Eva Nilsson; KTH; []
    Nyckelord :cancer; direct current; dose planning; electrochemical treatment; electrotherapy; mathermatical modelling; tumour;

    Sammanfattning : The electrochemical treatment (EChT) of tumours entails thattumour tissue is treated with a continuous direct currentthrough two or more electrodes placed in or near the tumour.Promising results have been reported from clinical trials inChina, where more than ten thousand patients have been treatedwith EChT during the past ten years.

  2. 2. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications

    Författare :Francesco Montecchio; Klas Engvall; Roberto Lanza; Ernest Blatchley III; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOP; UV; photocatalysis; ozone; air pollution; VOC abatement; reactor design; reactor modelling; photocatalyst support; electrochemical treatment; electrochemical etching; irradiation modelling; kinetics modelling; fluid dynamics simulation; prototype; full-scale; CFD simulation; Chemical Engineering; Kemiteknik;

    Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 4. Treatment of organic pollutants in high salinity wastewater : new catalysis systems

    Författare :Han Yu; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High salinity wastewater; Electrochemical catalysis; Photo-electro catalysis; Degradation;

    Sammanfattning : High salinity wastewater (HSW, NaCl mass fraction ≥ 1%) from industries and aquacultures contains massive organic matters with a wide variety. These organic matters have been considered as significant threaten to both human and environment. The removal and degradation of them before discharge emerge as necessity. LÄS MER

  5. 5. Study of Electrochemical Behaviour and Corrosion Resistance of Materials for Pacemaker Lead Applications

    Författare :Andreas Örnberg; Jinshan Pan; Jukka Lausmaa; Ann Cornell; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Co-base alloy; 35N LT; MP35N; Ta; TiN coating; electrochemical behaviour; corrosion resistance; Chemistry; Kemi;

    Sammanfattning : For patients suffering bradycardia, i.e., too slow heart rhythm, the common treatment is having a pacemaker implanted. The pacemaker system consists of the pacemaker and a pacing lead. LÄS MER
