  2. 1. Exploring Catalytic Tellurium-Based Antioxidants : Synthesis and Evaluation

    Author : Jia-fei Poon; Lars Engman; John Murphy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; radical-trapping; chain-breaking; ROS; glutathione peroxidase; tocopherol; aromatic amine; oxidative stress;

    Abstract : This thesis is concerned with the synthesis and evaluation of various tellurium-based chain-breaking antioxidants. The purpose is to find novel regenerable compounds with improved radical-trapping capacity.In the first part of this work, we explore the possibilities to incorporate tellurium into tocopherols and aromatic amines.

  4. 2. Mobilization and Management of Tellurium in Severe Accident Scenarios

    Author : Anna-Elina Pasi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nuclear; gamma irradiation; source term; severe accident; tellurium;

    Abstract : Safety is one of the highest priorities in any industry. In the nuclear industry, safety is in the essence since in case of a nuclear accident, the consequences can be long-lasting, hazardous, and devastating to the public, environment, and the industry. READ MORE

  5. 3. Volatized Tellurium Interactions with Organics and with Boric Acid

    Author : Fredrik Börjesson Sandén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile fission product; Severe nuclear reactor accident; Tellurium; boric acid;

    Abstract : Tellurium is a volatile fission product with a complex chemistry that must be accounted for in case of a nuclear accident. Specifically, its interactions with organic species and with boric acid, both which are expected in the accident chemistry, are largely unknown. READ MORE

  6. 4. Tellurium Behavior and Management in the Liquid Phases in the Containment During a Severe Nuclear Reactor Accident

    Author : Anna-Elina Pasi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; severe nuclear reactor accident; fission product; source term; tellurium;

    Abstract : No industry is immune to accidents; however, the consequences and the probability are the parameters to consider when assessing the risks. When considering nuclear power, two of the highest-level accidents have occurred during the course of the commercial use of nuclear energy. READ MORE

  7. 5. Electronic and optical properties of conducting polymers from quantum mechanical computations

    Author : Amina Mirsakiyeva; Anna Delin; Igor Zozoulenko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; density functional theory; DFT; Car-Parrinello molecular dynamics; CPMD; tigh-binding; poly 3; 4-ethylenedioxythiophene ; PEDOT; selenium; PEDOS; tellurium; PEDOTe; poly p-phenylene ; poly para-phenylene ; poly 1; 4-phenylene ; naphthobischalcogenadiazoles; Fysik; Physics;

    Abstract :     Conductive polymers are also known as "organic metals" due to their semiconducting properties. They are found in a wide range of applications in the field of organic electronics. However, the growing number of experimental works is not widely supported with theoretical calculations. READ MORE
