The IXth European Colloid and Interface Society (ECIS) Conference was
held in Barcelona, 71 - 22 September, 1995. It was attended by over 023 partici-
pants from 03 different countries. The scientific program was composed of 103
contributions 07( lectures and 132 poster communications). It covered the
theoretical, experimental and technical aspects of almost all fields of modern
Colloid and Interface Science.
This volume contains a selection of the contributions presented at the Confer-
ence. It si divided into the following sections:
Surfactant aggregates: Micelles, vesicles and liquid crystals
-
Colloidal particles: Interaction, structure and aggregation
-
- Emulsions and concentrated systems
Microemulsions
-
- Mixed colloidal systems
- Rheology
Biocolloids
-
- Interfaces, films and membranes.
On behalf of the Organizing Committee, we would like to thank all partici-
pants ftohre ir scientific contributions which resulted in successful a Conference.
eW are especially grateful to the members of the Scientific Committee, M. Corti,
H. Hoffmann, D. Langevin, H. Lekkerkerker, B. Lindman, M. A. L6pez
Quintela, C. Mans, .P Schurtenberger and Th. E Tadros. They helped us in the
difficult task of selecting the contributions for oral presentations from a rather
large number of high quality Abstracts.
We gratefullya cknowledge the support of the Faculty of Chemistry of the
University of Barcelona. They kindly allowed us to use their facilities in which to
hold the Conference.
eW also gratefully acknowledge the financial support from the European
Colloid and Interface Society and from the following Spanish Organizations:
Generalitat de Catalunya, Ministerio de Educaci6n y Ciencia (MEC), Univer-
sitat de Barcelona (UB), Real Sociedad Espafiola de Quimica (RSEQ), Consejo
Superior de Investigaciones Cientificas (CSIC), Mettler Toledo S.A.E., Petro-
quimicEas pafiola S.A., ICI Espafiola S.A. and Optilas Ib6rica S.A.
eW sincerely thank the staff of the "Department de Tecnoiogia de Tensioac-
tius" (CSIC) and the "Department d'Enginyeria Quimica i Metallurgia" (UB)
for their enthusiastic and efficient collaboration in the organization of the Con-
ference. eW are also indebtteod .rM and Mrs. Gurusfwoarm y their valuable and
generous help.
