  1. 1. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics

    Författare :Florian Burmeister; Eckart Rühl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Photoelectron spectroscopy; HCl; DCl; Dissociation dynamics; Born-Oppenheimer approximation; Synchrotron radiation; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.

  3. 2. Investigations of Chlorine-Induced High Temperature Corrosion of Steels

    Författare :Nicklas Folkeson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sulphur; alkali; chlorine; field exposures; HCl-induced corrosion; high temperature corrosion; deposits.; chloride-induced corrosion; waste; 310S; HCl;

    Sammanfattning : The high corrosivity of the fireside environment in waste and biomass fired boilers is commonly attributed to the presence of chlorine-containing compounds. Chlorine-induced high temperature corrosion is not well understood, however. LÄS MER

  4. 3. Study and Modeling of the Reduction of Sulfur Dioxide, Nitrogen Oxides and Hydrogen Chloride by Dry Injection Technologies

    Författare :Wuyin Wang; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reaction kinetics; pore particle size; HCl; NOx; desulfurization; Ca-based sorbent; flue gas; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : The potential and mechanism to reduce acid gases, such as SO2, NOx and HCl by dry Ca-based sorbents have been studied to improve the efficiencies of the process and sorbent utilization. Several natural limestones were tested for SO2 removal. Calcium conversion as high as 45% was achieved within 0.3 s at 1000°C, 1000 ppm SO2 and Ca/S=1. LÄS MER

  5. 4. Oxide Formation and Degradation during Erosion-Corrosion of Iron and Nickel Based Alloys

    Författare :Rikard Norling; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AES; fluidised bed; FBC; XPS; erosion-corrosion; SO2; crack formation; surface analysis; HCl; enhanced oxidation;

    Sammanfattning : Erosion-corrosion is, in many technical applications, a serious material degradation process caused by dynamic particle/fluid mixtures. Pipes transporting particle containing liquids, jet engines, gas turbines, and fluidised bed combustion (FBC) power plants are examples of systems which are considered to be especially susceptible.

  7. 5. Role of Melatonin, Neuropeptide S and Short Chain Fatty Acids in Regulation of Duodenal Mucosal Barrier Function and Motility

    Författare :Wan Salman Wan Saudi; Markus Sjöblom; Olof Nylander; Mark Berner-Hansen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; rat; in vivo; duodenum; enteric nervous system; paralytic ileus; parecoxib; bicarbonate secretion; motility; ethanol; HCl; melatonin; neuropeptide S; short chain fatty acids; chemosensing; Physiology; Fysiologi;

    Sammanfattning : The duodenal epithelium is regularly exposed to HCl, digestive enzymes, bacteria and toxins, and sometimes also to ethanol and drugs. The imbalance of aggressive factors in the intestinal lumen and mucosal barrier function increases the risk of tissue injury and inflammation. LÄS MER
