  2. 1. Intermolecular interactions in hydrogen bonded 1:1 molecular complexes. A matrix isolation study

    Author : Anders Engdahl; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; infrared laser irradiation; dimethyl ether; water dimer; hydrogen chloride; formamide; acetone; formic acid; ammonia; water; intermolecular; matrix isolation; FIR; FTIR; infrared; isomerisation; ab initio; Physical chemistry; Fysikalisk kemi;

    Abstract : A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. READ MORE

  4. 2. A Study of the Interaction between the HOO radical and some small Molecules

    Author : Thomas Svensson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; ab initio; peroxy radical; molecular interactions; matrix isolation; FTIR; infrared; Chemistry; Kemi;

    Abstract : The HOO radical is a key intermediate in the atmosphere and is involved in a large number of reactions, including ozone loss cycles in the stratosphere and oxidation processes in the troposphere. This theses is a study of the HOO radical and its interactions with a number of small molecules that are present in the atmosphere. READ MORE

  5. 3. Magneto-sensitive elastomers in vibration isolation

    Author : Ane Alberdi-Muniain; Leif Kari; N Gil-Negrete; Luigi Bregant; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Abstract : Vibration isolators made of rubber are used in numerous engineeringapplications to isolate structures from undesirable effects of vibrations.However, once a vibration isolator is installed in an application, it is not possible to modify its characteristics to adjust to changing conditions.

  6. 4. Constitutive models of magneto-sensitive rubber under a continuum mechanics basis and the application in vibration isolation

    Author : Bochao Wang; Leif Kari; Ines Lopez Arteaga; Vincent Coveney; KTH; []
    Keywords : Magneto-sensitive rubber; magnetic dependency; frequency dependency; amplitude dependency; temperature dependency; vibration isolation; Engineering Mechanics; Teknisk mekanik;

    Abstract : Due to its durability, stretchability, relatively low stiffness and high damping, rubber is widely used in engineering anti-vibration fields. However, a major deficiency is that once installed, the mechanical properties of traditional rubber-based devices are fixed where its adaptability to various loading conditions is poor. READ MORE
