1. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis
Abstract : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. READ MORE

2. Development of New Experimental Facilities at the Lund Nuclear Microprobe Laboratory
Abstract : Ion beam analysis techniques are now well established as research tools for a broad range of multidisciplinary scientific fields. The ability to focus an ion beam down to micrometer size has expanded and strengthened the capability of IBA techniques to a higher level. READ MORE

5. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi
Abstract : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. READ MORE
