Surface and Colloid Science

Leading Nordic-Baltic scientists and their colleagues from other countries present recent research on a broad range of topics in surface and colloid science:

• adhesion,
• adsorption processes,
• characterization of solid/liquid and solid/polymer interfaces,
• chemical and particle depositions,
• colloid stability,
• emulsification and encapsulation,
• interfacial reactions,
• new surfactants,
• polymer-surfactant interactions,
• self-assembly processes, - functionalized surfaces for bio- and chemosensors.
  The papers were presented at the 1st Nordic-Baltic Meeting on Surface and Colloid Science, which was held in Vilnius, Lithuania on August 21-25, 1999, as a continuation of the traditional Scandinavian Symposium on Surface Chemistry.
