    Sammanfattning : Catalytic reactions on solid surfaces have been studied under Ultra-high vacuum (UHV) conditions for decades. These studies provide crucial information for catalytic reactions, such as surface structures, adsorption sites, and reaction mechanisms. LÄS MER

  4. 3. New Materials and Improved Ambient Techniques in Mass Spectrometry

    Författare :Nicolò Riboni; Leopold Ilag; Elisa Robotti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Solid Phase Microextraction; Ambient Mass Spectrometry; Desorption Electrospray Ionization; Paper Spray Ionization; Cavitands; BTEX; New Psychoactive Substances; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Mass spectrometry (MS) is used in several fields, e.g. biology, environmental monitoring, medicine and forensics due to excellent qualitative and quantitative capabilities. The development of new instrumental setups and ionization sources is crucial to analyze a variety of compounds at trace levels. LÄS MER

  5. 4. Experimental Studies on Ambient Aerosol Hygroscopicity

    Författare :Erik Fors; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2011:Fors;

    Sammanfattning : The air around us is full of aerosol particles which originate from a myriad of sources and which have vastly different chemical and physical properties. These particles span size ranges from 1 nm to 100 μm, equivalent to a factor 100 000 in diameter difference and a factor 10^15 in volume difference. LÄS MER

  7. 5. Climatic conditions inside nuclear reactor containments - Monitoring campaign

    Författare :Mikael Oxfall; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear power plant; concrete; onsite measurements; relative humidity; boiling water reactor; pressurized water reactor; moisture transport coefficient; moisture flux.;

    Sammanfattning : The reactor containment is one of the most important buildings at a nuclear power plant. In case of an accident the containment wall is the final protection against radioactive leakage to the surrounding environment. A reactor containment contains different types of concrete structures.
