Manfred und StefanieiiPreface
This PhD thesis was carried out at the Institute of Physical and Theoretical Chem-
istry, Faculty of Natural Science IV, University of Regensburg, between October
2007 and January 2011, under the supervision of Prof. Dr. W. Kunz. This work
would not have been possible without the great support from many people. There-
fore, I want to express my profound gratitude to the following, who contributed to
the completion of my dissertation:
First of all, I would like to express my deepest gratitude to my supervisor, Prof.
Dr. W. Kunz, for giving me the opportunity to carry out this thesis at the Institute
of Physical and Theoretical Chemistry, for his commitment to guide me through my
research, for this interesting subject, the invaluable discussions we shared, and the
financial support provided in order to complete my thesis.
MysinceregratificationgoestoProf. Dr. GordonJ.T.Tiddyforthecountlesstime
he has spent supporting me on this subject. I cannot thank him enough for his ex-
pertise, knowledge, and for the many great scientific discussions. His contributions
are highly valued and regard with my utmost respect.
Dr. Didier Touraud is gratefully acknowledged for finding this excellent surfactant
for me to work with, while supporting me with many experimental ideas.
Special thanks to Dr. George Smith from the Huntsman Corporation (Texas, USA)
for providing the extended surfactant whenever it was needed. He has been of great
help with his valuable insights to questions concerning the extended surfactants.
Without this surfactant, this thesis would not have been possible.
Prof. Dr. Conxita Solans (CSIC, Barcelona, Spain) is gratefully acknowledged for
her enlightening thoughts on nano-emulsions, and her tremendous support.

In addition, I want to thank Prof. Dr. Hubert Motschman for giving me the op-
portunity to perform SAXS measurements at the MPI in Golm, Germany, and to
Gabriele Wienskol for performing the necessary experiments. In particular, many
thanks to Dr. Matija Tomˇsiˇc (University of Ljubljana, Slovenia), and Dr. Isabelle
Grillo (LLB, Grenoble, France) for their contribution on performing SAXS and
SANS measurements, respectively. Helga Garcia is recognized for her exceptional
performance conducting experimental tests on cytotoxicity and biodegradability of
the extended surfactant.
Special thanks to the University of Regensburg’s NMR Department, and especially
towards Annette Schramm and Georgine Stu¨hler for their willingness to conduct
NMR measurements as often as needed.
Thanks to PD. Dr. Reinhard and Dr. Markus Drechsler for their thoughtfulness,
generosity and support in performing the FE- and cryo-TEM measurements.
Michael Bodensteiner, from the Inorganic Department of the University of Regens-
burg, is gratefully acknowledged for his unsurpassed contribution on the analysis
of the cubic phase space group. In addition, the help of Claudia Niegel from the
analytical department (University of Regensburg) is acknowledged.
I would like to individually thank, Agnes Harrar, Eva Maurer, Susanne Dengler,
Michael Klossek, Andreas Eiberweiser, and Josef Eiblmeier from the Institute of
Physical and Theoretical Chemistry for their invaluable assistance on assessing my
thesis and providing me feedback on recommendations and suggestions. Eva Mau-
rer and Agnes Harrar, I relish our countless time spent on coffee breaks and long
(beer-)eveningsattheUniversitythatwasfilledwithgreatdiscussions. ReginaKlein
is also acknowledged for the information and advice she has provided and shared
with me. In addition, my gratitude extends out to Bj¨orn Barthel for his exceptional
performance on EDX measurements, which provided extensive information about
the extended surfactants. Thanks to all staff members for your generosity and for
creating a pleasant atmosphere in the laboratory that was enjoyable to work in.
Additionally, I would like to acknowledge and thank the students Anh Phong Trinh,
Heike Hack, Maria Helminger, Carmen Hoffendahl, and Philipp Schu¨del for their
contribution, dedication, and cooperative efforts on helping me with some experi-v
ments throughout the scope of this work.
Furthermore, I am gratefully thankful to Christine Thoms (Maus) for truly being
my best friend and a caring person with extraordinary support, both personally and
professionally. To Florian Pevny and Dr. Clement Padie, I am delighted and thank-
ful for the company they have both provided me during the numerous lunches filled
with endless laughter. Sincere thanks to Dr. Franziska Weichelt for her thoughtful-
ness and support towards the second half of this thesis.
Of course, to my loving parents, Manfred and Stefanie Klaus, and my brother,
Thomas Klaus, for their indescribable support and love they have always given me
throughout my lifetime endeavors.
Last, but not least, my sincere gratitude goes to my boyfriend, Peter Suh, for his
incredible encouragement and reinforcement not only throughout the progress of
this thesis, but ever since the moment I met him. From the bottom of my heart, I
thank you.vi
