  1. 1. Chemically Modified Metal Oxide Nanostructures Electrodes for Sensing and Energy Conversion

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Sami Elhag; Omer Nour; Magnus Willander; Alberta Bonanni; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Metal oxide nanostructures; mixed metal oxide nano-compound; low temperature wet-chemical growth; chemically modified electrode; doping; surfactant; potentiometric sensor; chemical sensor and photo-electrochemical activity;

    Abstract : The goal of this thesis is the development of scalable, low cost synthesis of metal oxide nanostructures based electrodes and to correlate the chemical modifications with their energy conversion performance. Methods in energy conversion in this thesis have focused on two aspects; a potentiometric chemical sensor was used to determine the analytical concentration of some components of the analyte solution such as dopamine, glucose and glutamate molecules.

    Abstract : Partial pressure of CO2 (pCO2) is one of the most important parameters, which are measured in the global ocean in conjunction with ocean acidification studies. It is also a parameter of great interest to aquaculture and fish industries since CO2 in large amounts is highly toxic for animals. The requirements for pCO2 measuring systems, e.g. READ MORE
