1. 6. Ion pairing and Langmuir-like adsorption at aqueous surfaces studied by core-level spectroscopy

   Författare :Victor Ekholm; Olle Björneholm; Jan-Erik Rubensson; Markus Ammann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; XPS; Surface; Aqueous; Liquid jet; Langmuir;

   Sammanfattning : Surface-bulk equilibria for solutes in aqueous solutions are studied using X-ray Photoelectron Spectroscopy (XPS) with high surface and chemical sensitivity. In the first part, the results show a reduction of the biochemically relevant guanidinium ions’ surface propensity with the addition of disodium sulphate due to ion pairing with the strongly hydrated sulphate ion, which could have implications for protein folding.

4. 8. Polymers in Aqueous Lubrication

   Författare :Junxue An; Per M. Claesson; Martin Malsten; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lubrication; boundary lubrication; friction; surface forces; adsorption; adsorption hysteresis; non-equilibrium state; diblock copolymer; polyelectrolyte; thermoresponsive; mucin; QCM-D; ellipsometry; AFM; Kemi; Chemistry;

   Sammanfattning : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. LÄS MER

5. 9. Aspects on prostanoid and cholinergic effects on aqueous humour dynamics in human eyes

   Författare :Christina Lindén; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aqueous flow; blood-aqueous barrier; flare; human; intraocular pressure IOP ; latanoprost; physostigmine; prostaglandins; uveoscleral flow;

   Sammanfattning : The discovery of the ocular hypotensive effect of topically applied prostaglandins (PGs) has raised a number of questions about the mechanisms of action involved. The aim of the present thesis was to answer some of these questions. LÄS MER
