    Abstract : Anthropogenic carbon dioxide (CO2) emissions have become a critical environmental issue because a large amount of CO2 releasing into the atmosphere, particularly from the massive use of fossil fuels, is the major factor promoting the global warming and climate change. To mitigate the CO2 emissions, Carbon Capture, Utilization and Storage (CCUS) can be one of important solutions. READ MORE

  2. 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 : 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;

    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
