1. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees
Sammanfattning : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). LÄS MER
2. On metal ion chelates and conditional stability constant determination : Method development and selective ion flotation of chelating surfactants

3. Naturally occurring phenols with antioxidant, antifungal and anti-browsing activity
Sammanfattning : .... LÄS MER
4. Improved hydrogene peroxide bleaching of mechanical pulps through fundamental understanding of the influence of heat, iron, fines and chemical treatment on chromophore content
Sammanfattning : .... LÄS MER
5. Biochemical Interactions of Some Saproxylic Fungi
Sammanfattning : Interactions are all around us, and as humans we may use words and gestures to communicate our intentions. At the micro level of fungi, communications are replaced by chemical signals and structure. LÄS MER
