Amphiphilic diblock copolymers for molecular recognition
No full textIn this thesis, the synthesis and the characterization of poly(butadiene)-blockpoly(
ethylene oxide) copolymers with terminal Me2+-NTA groups (copper or nickel) is
described for the first time. A convenient “one-pot” procedure that allows control over the
individual block lengths of the copolymer and the end-group functionalization was
successfully established.
The formation of the metal-polymer complex has been confirmed by EPR and UV/VIS
spectroscopy. Mixing of the Ni2+-NTA polymers with the corresponding non functionalized
block copolymers at a concentration of 10 mol% does not affect the self-assembly behavior
of the mixtures, i.e., in dilute aqueous solutions the polymer mixtures aggregate to vesicular
structures (metal-doped vesicles) with identical size distribution as the non functionalized
block copolymer vesicles. Vesicles were characterized by dynamic light scattering, static
light scattering, small angle X-ray scattering and zeta potential. All measurements led to the
conclusion that hollow spheres, i.e. vesicles, with a narrow size distribution and a negative
surface potential were generated. Moreover different vesicle shapes as “necklace pearls”,
“wormlike micelles” and “spermasomes” can be attributed to different salt solutions or
buffers of defined concentrations which suggests a control of morphology.
The accessibility of the metal sites at the surface of such vesicles has been tested using
fluorescence correlation spectroscopy. The model proteins His10-MBP-FITC and His6-EGFP
bind selectively to the Me2+-NTA groups exposed at the surface of the vesicles. While the
choice of the buffer significantly influenced the fractions of protein-vesicle conjugates, the
interactions of Cu2+- and Ni2+-NTA groups with both His-tagged proteins showed similar
values. It should be noted that the experimentally determined dissociation constants of the
Me2+-His-Tag complexes were found to be in good agreement with literature data on Ni-
NTA functionalized liposomes14, indicating that the polymer brushes at the polymer vesicle
surface only slightly interfere with the binding of the proteins.
Fluorescence Microscopy was used to visualize the binding of the fluorescent proteins to
the functionalized vesicles and images of vesicles with a fluorescent corona were taken.
Additionally, atomic force microscopy clearly demonstrated that the polymer adsorbs in
an oriented manner on highly oriented pyrolytic graphite surfaces and is able to induce a 2D
protein crystallization when Ni-NTA functionalized polymer was used.
We believe that these metal-functionalized polymeric membranes have a large potential
for the selective immobilization and alignment of proteins at vesicle/planar membrane
surfaces. In particular, the high flexibility and compressibility of block copolymer membranes
and monolayers could open new possibilities for inducing a 2D protein crystallization. The
high cohesion and robustness of block copolymer membranes make them rather insensitive
toward mechanical shear or the presence of detergents, increasing their potential utility. In
this context, it should also be noted that the pendant double bonds of the poly(butadiene)
blocks can be covalently cross-linked, thus freezing the self-assembled structures and
providing additional stabilization

Nauczanie języka polskiego na Uniwersytecie Wrocławskim w czasach Władysława Nehringa
No full textTeaching of Polish at the University of Wrocław in Władysław Nehring’s timesThe article examines the teaching of the Polish language at the University of Wrocław in the second half of the 19th century, when the Department of Slavic Literatures and Languages was chaired by Władysław Nehring. The author lists and briefly describes language teachers working there at the time Jan Mikołaj Fritz, Wincenty Kraiński, Rafał Löwenfeld and Rudolf Abicht as well as the conditions in which they worked. She also presents language textbooks used at the university, pointing to their characteristic features and interesting methodological solutions. The textbooks included J. Popliński’s Grammatik der polnischen Sprache nach Kopczyński, Cassius, Bandtke und Mroziński, several editions of which were published. Two editions were by Władysław Nehring, who incorporated into them more recent developments in 19th-century linguistics. Under Nehring’s leadership the teaching of Polish developed, though it was constantly plagued by staff- and funding-related problems.Teaching of Polish at the University of Wrocław in Władysław Nehring’s timesThe article examines the teaching of the Polish language at the University of Wrocław in the second half of the 19th century, when the Department of Slavic Literatures and Languages was chaired by Władysław Nehring.

Thomas Mann: Ästhetizismus und die Denkstruktur des Einerseits-Andererseits – mit Bezug auf «Wälsungenblut»
No full textThomas Mann is an author without a fixed point of view. When he discusses a problem he tends to opt for an «on the one hand – on the other hand». His novella Wälsungenblut is the epitome of aestheticism. How is this aestheticism portrayed? For once the author appears to be unfaithful to his typical way of thinking and to give way to satire. One of the most interesting aspects is how Richard Wagner’s Walküre is included in this argument
Prince Eugene and Maria Theresa: Gender, History, and Memory in Hofmannsthal in the First World War
No full textHugo von Hofmannsthal was one of the Austrian poets and intellectuals who took an active part in the historical-political events of 1914. He expected from the war a new vitality of public life and an end of the cultural crisis. In his early years he had advocated closer bonds between poesy and life. Now he encountered a situation that gave him the chance to strengthen his ties with reality. He worried about the existence of Austria, in which he was rooted, and tried to conjure up the Hapsburg spirit of the past for his contemporaries and to explain Austria's national history and right to exist to a large public. My study discusses his essay on Prince Eugene and Maria Theresa in the context of collective memory (or cultural memory) and propaganda. Is there really a collective memory? Was there a collective memory, in which the great commander and the empress lived on, or did the author wish to create this memory from history? Should his essays be considered war propaganda? Self-assertion of Austria opposite the German ally appeared almost equally important. The change in emphasis from Prince Eugene as the greatest Austrian to the peace-loving empress mirrors the events of the war. Both contribute to an Austrian anthropology, which for the author lived on beyond the end of the Empire
1968: A Social Movement Sui Generis
No full textThis contribution starts out with a brief survey of key events in 'global 1968', which is defined as a social movement mobilization cycle lasting, approximately, from 1956 to 1976. After a discussion of key overall determinants engendering this particular moment of crises and opportunities, '1968' is then analyzed as the very first-ever transcontinental revolt, a tripartite rebellion linking up protest movements in various parts of the world: radical students and workers in First World countries, anti-bureaucratic dissident currents in the Second World; and national liberation movements in the Third World
