  1. 1. Experimental studies of cluster ions containing water, ammonia, pyridine and bisulphate

    Författare :Mauritz Johan Ryding; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clusters; ions; water; ammonia; pyridine; bisulphate; cross sections; collision induced dissociation CID ; kinetic modelling; electrospray ionization ESI ; time-of-flight TOF ; mass spectrometry;

    Sammanfattning : Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behaviour and properties. LÄS MER

  7. 5. Computational Studies of Nitrogenase

    Författare :Lili Cao; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogenase; QM MM; quantum refinement; FeMo cluster; E4 state; N2 binding; V-nitrogenase; P-cluster; S2B dissociation; broken-symmetry state; homocitrate; DFT; protonation state; disorder; ComQumX-2QM;

    Sammanfattning : AbstractNitrogenase is the only enzyme that can convert the inert nitrogen molecule to ammonia, so that it can be used for biomass production and in biosynthetic pathways. It contains a complicated acitve site, composed of eight metal ions, nine sulfur ions and one carbide ion (the FeMo cluster). LÄS MER
