From self assembled monolayers to clickable gold nanoparticles
No full textThe aim of the present PhD thesis was the investigation of the behavior of gold nanoparticle stabilizing oligo thioether ligands on gold surfaces and further on to develop a protocol for the directed assembly of mono functionalized gold nanoparticle into defined oligomer structures.
Outline
The present cumulative PhD thesis consists of the following parts:
In the Introduction the research field of gold nanoparticles is presented with to point out their unique electronic and physical properties. The second focus will be on the controlled interlinking and functionalization of gold nanoparticles using click chemistry and their potential applications, which will be submitted as a review article.
Within Concept and Strategy the goals of the research project are introduced and the concepts and outputs of the resulting publications are presented.
The Publications are accumulated with their respective Supporting Information, in the order in which they were prepared:

NUEVO OPERE DI RALF SANDER ENTANGLEMENT, La Serpara Museum
No full textRalf Sander investigates the relevance of transformation, invisibility and belief for the art. During his Exhibition in La Serpara Museum and sculpture garden, Ralf Sander presented a series of images and prints, protected in dark boxes and a thought manipulation machine, the Apocalytor. Once the images are exposed to light they will disappear. The images are portraits. The installation is comparable with the " Schroedinger`s Cat" experiment. It is a thought experiment, sometimes described as a paradox, by Austrian physicist Erwin Schrödinger in 1935 It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. Also other techniques for image disappearance were developed in a rigorous process of series of experiments. The Machine is a sculptural construction exploring the use of fear to reduce our human rights, a powerful instrument of manipulation which will have you asking questions about the world in which we live. It contains a sound installation, whispered quotes of news and also the last interview with George Orwell about his Book 1984. In his installation Sander started to investigate mechanism of manipulation such as creating fear, fake news and felt truth

Gulliver`s Travels
No full textIn this work Ralf Sander explores the impact of reflection on public sculpture. It breaks down the traditional divide between viewer and art object, putting the viewer literally into the work of art. He started to experiment with reflection and distortions to achieve the target of a vanishing image. Sander designed a sculpture that refers to Jonathan Swift`s Gullivers Travels. One moment you are a giant the other you become a dwarf or the world turns upside down. The sculpture that takes visitor on Gulliver`s Travels. Finally seeing the distorted images we can start to laugh about our reflections

Comparison of Growth in Pike-Perch (Sander lucioperca) and Hybrids of Pike-Perch (S. lucioperca) × Volga Pike-Perch (S. volgensis)
No full textGrowth of intensively cultured pike-perch Sander lucioperca (L.) and hybrids of pike-perch females × Volga pike-perch (S. volgensis Gmelin, 1789) males (1.75 g) were compared in a 35-day experiment. Fish were sorted into three groups (50 fish/aquarium): S. lucioperca grown separately (Group P), hybrids grown separately (Group H), and a mixed group of 25 S. lucioperca (Group Mp) grown together with 25 hybrids (Group Mh). The stocking density was 0.44 g/l. Final body weights were 6.83 g, 6.54 g, 5.17 g, and 4.84 g, and specific growth rates were 3.9%/day, 3.75%/day, 3.1%/day, and 2.89%/day, for groups Mp, P, Mh, and H, respectively. The weight, length, and specific growth rates of the S. lucioperca were significantly higher (p<0.05) than those of the hybrids, whether grown separately or together. The feed conversion rate of the hybrids grown separately was significantly higher (1.28 g/g) than all other groups. Further investigation is needed to study the growth performance of larger hybrids, to compare the hybrid with S. volgensis, and to investigate the possibility of cross hybridization
