1. Biologically Interesting Compounds from Natural Sources
Sammanfattning : Natural products have traditionally played a major role in the drug discovery process. Besides constituting extremely popular drugs in the market, and an ever-increasing source of interesting and novel chemical structures, they have also aided the characterization of many a pharmacological target.

2. Characterization of Secondary Metabolites from Natural Sources
Sammanfattning : Natural products have contributed for many years to the development of new medicines for the treatment of diseases. Their structural diversity and complexity have inspired chemists to produce interesting compounds with pharmaceutical use. LÄS MER
3. Road traffic metals : sources and emissions
Sammanfattning : As the environmental regulations and technical progress have forced the factories’ old “end of pipe” solutions to improve, the metal emissions from point sources have decreased. Instead, the diffuse consumption emissions from goods in use now are in focus. LÄS MER
4. Natural products from Bolivian plants and other sources
Sammanfattning : The present research was focused on the phytochemical research of Bolivian plants; a) two medicinal ones Aniba canelilla and Iryanthera juruensis, both plants showed to have compounds with biological activity in different fields. Even though Aniba canelilla was studied before, new compounds were identified in this investigation. LÄS MER
5. Ultra-short-chain perfluoroalkyl acids : Environmental occurrence, sources and distribution
Sammanfattning : Ultra-short-chain perfluoroalkyl acids (PFAAs) is a group of highly fluorinated and very stable chemicals. Their small molecular structure in combination with the acidic functional group result in highly polar compounds and concern has been raised as these substances may threaten our drinking water supplies.
