  2. 11. Theoretical Studies of Ground and Excited State Reactivity

    Author : Pooria Farahani; Marcus Lundberg; Hans Karlsson; Isabelle Navizet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical Reactivity; Computational Chemistry; Dynamics; Ground and Excited States; Chemiluminescence; Atmospheric Chemistry;

    Abstract : To exemplify how theoretical chemistry can be applied to understand ground and excited state reactivity, four different chemical reactions have been modeled. The ground state chemical reactions are the simplest models in chemistry. To begin, a route to break down halomethanes through reactions with ground state cyano radical has been selected. READ MORE

  4. 12. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

    Author : Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. READ MORE

  5. 13. Reactivity Assessment in Subcritical Systems

    Author : Carl-Magnus Persson; Janne Wallenius; Waclaw Gudowski; Annick Billebaud; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reactor Physics; Nuclear physics; Kärnfysik;

    Abstract : Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. READ MORE

  6. 14. On measurement and monitoring of reactivity in subcritical reactor systems

    Author : Carl Berglöf; Janne Wallenius; Vasily Arzhanov; Massimo Salvatores; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reactor; ADS; accelerator-driven systems; subcriticality determination; noise techniques; pulsed neutron source; reactivity monitoring; Nuclear physics; Kärnfysik;

    Abstract : Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. Experience has shown that the performance of reactivity measurement methods in terms of accuracy and applicability is highly system dependent. READ MORE

  7. 15. Biomimetic Iron Complexes involved in Oxygenation and Chlorination : A Theoretical Study

    Author : Holger Noack; Margareta R. A. Blomberg; Per E. M. Siegbahn; Martin Kaupp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biomimetic; iron; density functional theory; intradiol; chlorination; adpic acid; diamond core; reactivity; Bio-inorganic chemistry; Bio-oorganisk kemi; Theoretical chemistry; Teoretisk kemi; kemisk fysik; Chemical Physics;

    Abstract : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. READ MORE
