1. Avdunstning och molekyler : en longitudinell studie av hur grundskoleelever utvecklar sina uppfattningar om avdunstningsfenomen
Sammanfattning : This thesis presents results from a longitudinal study of students in compulsory school. The project started in spring 1997 when the students were about six years old, and finished in spring 2006 when they left compulsory school. LÄS MER
2. Avdunstning och molekyler : en longitudinell studie av hur grundskoleelever utvecklar sina uppfattningar om avdunstningsfenomen
Sammanfattning : Denna avhandling presenterar resultat från en longitudinell studie i grundskolan. Projektet startade våren 1997 då eleverna var omkring sex år och avslutades våren 2006 då eleverna lämnade grundskolan. Ett mål med studien var att följa individuella elevers begreppsutveckling kring avdunstning under deras år i skolan. LÄS MER
3. X-ray spectroscopy on diatomic and cationic molecules
Sammanfattning : X-ray spectroscopy have been used to study the electronic structure of diatomic and cationic molecules. X-ray absorption spectra of the molecular cations N2+, O2+, and CO+ have been measured. LÄS MER
4. Om strålning och molekyler i mörka moln
Sammanfattning : This thesis, which consists of five articles in English and a summary in Swedish, deals with observations and theoretical studies of dark interstellar clouds, and with a method for calculations of radiative transfer. Article 1 is a catalogue of bright nebulosities in dark clouds, based on a survey of photographic sky atlases. LÄS MER
5. Small and Large, Charged Molecules in Solution and at Interfaces
Sammanfattning : The influence of small and large, charged molecules on the properties of aqueous interfaces has important implications in chemistry, biology, and medicine. For example, at the surface of marine aerosols, the presence of halide anions and tropospheric gases gives way to multiphase chemical reactions affecting climate and air quality. LÄS MER
