We have studied the reaction of phenylacetylene (PA) with chloro-, bromo-, and iodobenzene on the Au(1 1 1) surface as a model system for the gold-catalysed Sonogashira cross-coupling. Both ultrahigh vacuum-based and ambient pressure x-ray photoelectron spectroscopy show that iodo- and chlorobenzene (IB and CB) undergo the cross-coupling reaction towards diphenylacetylene. Bromobenzene (BB), in co
Biomass densification elevates the bulk density of the biomass, providing assistance in biomass handling, transportation, and storage. However, the density and the chemical/physical properties of the lignocellulosic biomass are affected. This study examined the changes introduced by a briquetting process with the aim of subsequent processing for 2nd generation bioethanol production.

In this study we report on the adsorbate structures on an Ir(1 1 1) surface during the phase transition from the inactive to the active state during CO oxidation. The CO oxidation over Pt(1 1 1) is used as a reference case. Where Pt(1 1 1) either is inactive and CO covered or active and O covered, Ir(1 1 1) exhibits a transition state with co-existing chemisorbed O and CO. The observed structural
Path integration is a widespread navigational strategy in which directional changes and distance covered are continuously integrated on an outward journey, enabling a straight-line return to home. Bees use vision for this task-a celestial-cue-based visual compass and an optic-flow-based visual odometer-but the underlying neural integration mechanisms are unknown. Using intracellular electrophysiol
A substantial literature has grown up around the issue of how inward direct investment affects host countries. On almost every aspect of this question, there seems to be a wide range of empirical results in academic literature, and little sign of convergence. It is our purpose here to try to understand why contradictory results seem to be found by different investigators. Is it that the statistica
The group of small poor cods and pouts from the genus Trisopterus, belonging to the Gadidae family, comprises four described benthopelagic species that occur across the North-eastern Atlantic, from the Baltic Sea to the coast of Morocco, and the Mediterranean. Here, we combined molecular data from mitochondrial (cytochrome b) and nuclear (rhodopsin) genes to confirm the taxonomic status of the des
Antologin ger en bred bild av socialt arbete i civilsamhället, som både ”röst” och ”service”, och i olika grad av organiserade former. Här synliggörs både vad vi kallar ”Vi- för-dem”- organisationer som har hemlöshet, vård och arbetsträning på sin agenda, liksom ”Vi-för-oss”- organisationer såsom kvinnojourer och verksamheter som samlar människor med psykisk skörhet eller annan funktionsvariation.

Att kunna redovisa resultat ser vi i dagens samhälle som en självklar del av en organisations verksamhet. Privata profitdrivna företag liksom även alltmer offentliga organisationer styrs idag genom en marknadslogik som bland annat bygger på kontraktsbaserade uppdrag vilka förutsätter en granskning av hur de offentliga medlen används. Liknande krav på att utvärdera resultat och framgång blir i allt
