  1. 1. Reactivity of Metal Clusters with Diatomic Molecules

    Author : Lotta Holmgren; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nbn; cluster; reactivity; Rhn; NO; D2; CO; N2; laser vaporization; Wn; Nin; photoionization; time-of-flight mass spectrometer; ionization potential; Cun; O2; Vn;

    Abstract : The reactivity of transition-metal clusters, in the approximate size range 10-60 atoms, with diatomic molecules has been investigated. A pulsed beam of neutral clusters is produced by a laser-vaporization source and passed through a low-pressure reaction cell containing the reactive gas. READ MORE

  2. 2. Metabolic and Cardiovascular Responses During Variable Intensity Exercise

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Glenn Björklund; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cross-country skiing; cycling; heart rate; lactate; O2 extraction; O2 uptake; performance; ventilation; INTERDISCIPLINARY RESEARCH AREAS Sports; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Idrott;

    Abstract : Previous research investigating endurance sports from a physiological perspectivehas mainly used constant or graded exercise protocols, although the nature ofsports like cross-country skiing and road cycling leads to continuous variations inworkload. Current knowledge is thus limited as regards physiological responses tovariations in exercise intensity. READ MORE

  3. 3. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Mats Andersson; [1995]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; O2; CO; ionization potential; Con; Fen; NO; sticking probability; laser ionization; D2; Wn; Cun; Rhn; reaction probability; cluster; jellium model; Nbn; metal cluster reactivity; N2; time-of-flight mass spectrometry; Nin;

    Abstract : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. READ MORE

  4. 4. On the Character of Active Sites in Copper Exchanged Zeolites during NH3-SCR

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Lin Chen; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cu-SSZ-13; SSIE; O2-dissociation; Al-distribution; NH3-SCR; Chabazite; O2-activation;

    Abstract : Nitrogen oxides (NOx) are formed during combustion in diesel engines and one current approach to reduce NOx to N2 is selective catalytic reduction with NH3 as reducing agent (NH3-SCR). To acquire both high activity and selectivity, the active site is often atomically dispersed metal atom, so-called single-site catalysts. READ MORE

  5. 5. Development and use of an optical pCO2 sensor in marine studies

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Dariia Atamanchuk; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pCO2; O2; sensor; optode; cross-sensitivity; carbonate system of seawater; biogeochemistry; Redfield ratio; the Koljo Fjord; cabled observatory; CCS; QICS; environmental engineering; leakage detection; MVDA; DoE;

    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
