1. Investigating polymorphism in small molecules using three-dimensional electron diffraction
Sammanfattning : For scientific, regulatory and intellectual property reasons, the discovery and characterisation of polymorphic systems is an integral aspect of the development process of any solid-formulated drug product. Yet, these studies are often hindered by crystal quality and size, poor yields and the generation of mixtures of phases. LÄS MER
2. Rapid analysis of actinide isotopes using quadrupole ICP-MS for emergency preparedness and environmental monitoring
Sammanfattning : Transuranium elements in the environment are mainly derived from nuclear weapons testing and the nuclear fuel cycle. Of growing concern are illicit nuclear trafficking and the threat of terror acts. LÄS MER
3. Development of an adductomic approach to identify electrophiles in vivo through their hemoglobin adducts
Sammanfattning : Humans are exposed to electrophilically reactive compounds, both formed endogenously and from exogenous exposure. Such compounds could react and form stable reaction products, adducts, at nucleophilic sites in proteins and DNA. LÄS MER
4. Organohalogen contaminants in wildlife from the Yangtze River Delta : Development of methods and assessments of legacy and emerging persistent organic pollutants
Sammanfattning : Rapid economic development has occurred during the past few decades in China with the Yangtze River Delta (YRD) area as one of the most progressive areas. The urbanization, industrialization, agricultural and aquaculture activities result in extensive production and application of chemicals. LÄS MER
5. Generation, stability and migration of montmorillonite colloids in aqueous systems
Sammanfattning : In Sweden the encapsulated nuclear waste will be surrounded by compacted bentonite in the granitic host rock. In contact with water-bearing fractures the bentonite barrier may release montmorillonite colloids that may be further transported in groundwater. LÄS MER
