2. 1. Associative Multicomponent Polymers in Bulk and at Interfaces

   Author : Fredrik Joabsson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer adsorption; polymer self-diffusion; polymer-surfactant interactions; phase behaviour; ethyl hydroxyethyl cellulose; hydrophobically modified polymers; capillary-induced phase separation; Physical chemistry; Fysikalisk kemi;

   Abstract : The solution and interfacial properties of an associative water-soluble cellulose derivative, ethyl(hydroxyethyl)cellulose (EHEC) have been investigated. Main themes have been to study the effect of hydrophobic modification of the polymer (HM-EHEC) and the interactions with surfactants, both in bulk and at interfaces. READ MORE

4. 2. Methane dynamics in northern wetlands: Significance of vascular plants

   Author : Anna Joabsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic ecology; marine biology; Hydrobiology; Växtekologi; Plant ecology; climate change; arctic wetlands; northern wetlands; plant-microbe interactions; methane emission; vascular plants; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

   Abstract : The studies presented in Papers I to VI illustrate several different aspects of the impact of vascular plants on methane emissions from northern natural wetlands. The subject has been approached on different scales, ranging from the study of microbial substrates in the vicinity of a single plant root, to an attempt to extrapolate some of the results to the entire northern hemisphere north of 50°N.
