1. 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
2. Molecular Beam Studies of Interactions Between Ice Surfaces and Atmospherically Relevant Molecules
Sammanfattning : The discovery of the ozone hole over Antarctica in 1985 was one of the environmental issues that attracted most attention worldwide in the end of the last century. The cause of the ozone hole formation was proven to be coupled to the emission of chlorofluorocarbons (CFCs). LÄS MER
3. Cyanobacteria in symbiosis with boreal forest feathermosses : from genome evolution and gene regulation to impact on the ecosystem
Sammanfattning : Among dinitrogen (N2)-fixing some cyanobacteria can establish symbiosis with a broad range of host plants from all plant lineages including bryophytes, ferns, gymnosperms, and angiosperms. In the boreal forests, the symbiosis between epiphytic cyanobacteria and feathermosses Hylocomium splendens and Pleurozium schreberi is ecologically important. LÄS MER
4. Experimental studies of ice particle formation with tropospheric relevance
Sammanfattning : In their fourth assessment report, the Intergovernmental Panel on Climate Change points out the influence of particles suspended in air, known as an aerosol, as the main uncertainty in the understanding of the climate system. Aerosols affect climate in a number of ways. LÄS MER
5. Förbehandling av sulfatmassa och sulfatlignin med kväveoxider
Sammanfattning : .... LÄS MER
