Forskningsöversikt (refereegranskat)abstract
- Extensive experimental data from high-energy nucleus-nucleus collisions were recorded using the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The comprehensive set of measurements from the first three years of RHIC operation includes charged particle multiplicities, transverse energy, yield ratios and spectra of identified hadrons in a wide range of transverse momenta (PT), elliptic flow, two-particle correlations, nonstatistical fluctuations, and suppression of particle production at high PT. The results are examined with an emphasis on implications for the formation of a new state of dense matter. We find that the state of matter created at RHIC cannot be described in terms of ordinary color neutral hadrons.

Tidskriftsartikel (refereegranskat)abstract
- A chromogenic azobenzene compound, (E)-(3,3'-(diazene-1,2-diyl)bis(3,1-phenylene))bis(diphenylmethanol), forms lattice inclusion compounds with a range of common solvents. It is yellow in the unsolvated crystalline form, but orange or orange-red when crystallized as solvates with guest molecules that contain hydrogen-bond acceptors. Close examination of crystal structures of unsolvated and solvated forms reveals that differences in hydrogen bonding and a change in conformation of the azobenzene core are responsible for the change in lambda of absorption of the chromophore and hence color of the crystals. Hirshfeld surfaces and fingerprint plots reveal subtle differences in intermolecular interactions in the solvated and unsolvated crystalline forms.
