Tidskriftsartikel (refereegranskat)abstract
- Based on a recent ab initio interaction-induced dipole surface of collisionally interacting molecular hydrogen pairs H2–H2, we compute the binary absorption coefficients at wavelengths near 5 micrometers at temperatures of 77.5 and 297 K for comparison with existing laboratory measurements. We observe satisfactory agreement of the measurements with our calculations, thereby concluding an earlier study [Gustafsson et al., J. Chem. Phys. 119, 12264 (2003)], which was based on an ab initio interaction-induced dipole surface that was inadequate for the 5 micrometer band.

Tidskriftsartikel (refereegranskat)abstract
- The mechanism for hydrogenation of dimethylmaleate in water using cationic rhodium complexes with water-soluble bi-dentate phosphines has been investigated using kinetics and a novel method for the indirect detection of intermediates in catalytic hydrogenation reactions, whereby a late intermediate was detected. A mechanism is proposed involving fast, irreversible substrate binding followed by a rate-determining reaction with dihydrogen.

Tidskriftsartikel (refereegranskat)abstract
- Addition of i-PrMgCl to pyridine N-oxides in THF at −78 °C generates selectively an ortho-metallated species, which can be trapped with various electrophiles to generate 2-substituted pyridine N-oxides. Furthermore, by applying a double metal-catalyzed cross-coupling, direct arylation of the pyridine N-oxides is achieved.

Rate coefficient of CN formation through radiative association: A theoretical study of quantum effects
- 2009

Ingår i: J. Chem. Phys.. - : AIP Publishing. ; 131

Tidskriftsartikel (refereegranskat)abstract
- Radiative association of CN is simulated using a quantum dynamical as well as a semiclassical approach. A comparison of the resulting energy-resolved cross sections reveals striking quantum effects that are due to shape resonances. These, in turn, arise because of states that are quasibound by the centrifugal barrier. The quantal rate coefficient for temperatures from 40 to 1900 K has been computed using the Breit–Wigner theory to account for the resonances. Comparison with the results obtained by Singh and Andreazza [ Astrophys. J. 537, 261 (2000) ] shows that the semiclassical method, which completely omits the shape resonances, is accurate to within 25% above room temperature. At lower temperatures the contribution from the shape resonances to the radiative association rate is more significant.

STATIC! The Aesthetics of Energy in Everyday Things

Ingår i: Proceedings of Design Research Society Wonderground International Conference 2006.

Konferensbidrag (refereegranskat)abstract
- Abstract: Static! is a project investigating interaction and product design as a way of increasing our awareness of how energy is used in everyday life. Revisiting the design of everyday things with focus on issues related to energy use, we have developed a palette of design examples in the form of prototypes, conceptual design proposals and use scenarios, to be used as a basis for communication and discussion with users and designers. With respect to design research and practice, the aim has been to develop a more profound understanding of energy as material in design, including its expressive and aesthetic potential, thus locating issues related to energy use at the centre of the design process.

- Pervasive gaming has the potential of transforming the home into a persuasive environment in which the user can learn about appliances and their electricity consumption. Power Explorer is a mobile game with a special sensing approach that provides real-time electricity measurements and feedback when the user switches on and off devices in the home. The game was developed based on persuasive principles to provide an engaging means to learn about energy with positive and negative feedback and social feedback from peers on real energy actions in the home. We present the design and rationale of this game and discuss how pervasive games can be viewed from a persuasive and learning point of view. © 2009 Authors and Digital Games Research Association (DiGRA).

Measurement of the eta -> pi(+)pi(-)e(+)e(-) decay branching ratio

- The reaction pd -> He-3 eta at threshold was used to provide a clean source of eta mesons for decay studies with the WASA detector at CELSIUS. The branching ratio of the decay eta -> pi(+)pi(-)e(+)e(-) is measured to be (4.3 +/- 1.3 +/- 0.4) x 10(-4).
