  abstract  = {5. W{\"u}rzburger Wirtschaftssymposium, 20.11.2008 Deutsche Erfindungen ver{\"a}ndern die Welt - heute wie vor 500 Jahren. Von Buchdruck, {\"u}ber Dieselmotor, Gl{\"u}hbirne bis hin zu Airbag, Aspirin, D{\"u}bel, Fernseher und mp3-Format. Alleine dieser bescheidene {\"U}berblick des Ph{\"a}nomens "Made in Germany" l{\"a}sst den Betrachter die Bedeutung und das Potenzial von Innovationen am Standort Deutschland schnell erkennen. Experten aus Wirtschaft, Politik und Gesellschaft setzten sich am 20.11.2008 unter der Leitfrage: "Innovationen - Performancetreiber und nachhaltiger Wirtschaftsmotor in Deutschland?" mit der Bedeutung von Innovationen f{\"u}r den Standort Deutschland auseinander. Die Festschrift rundet - neben Interviews mit und Gastbeitr{\"a}gen von Referenten der Veranstaltung - das 5. W{\"u}rzburger Wirtschaftssymposium mit Stellungnahmen und Beitr{\"a}gen renommierter Experten ab. Zu Wort kommen dabei Jungunternehmer ebenso wie Wissenschaftler der Universit{\"a}t W{\"u}rzburg und Vertreter externer Organisationen.},

  abstract  = {New multifunctional nanoparticles (NPs) that can be used as contrast agents (CA) in different imaging techniques, such as photoluminescence (PL) microscopy and magnetic resonance imaging (MRI), open new possibilities for medical imaging, e.g., in the fields of diagnostics or tissue characterization in regenerative medicine. The focus of this study is on the synthesis and characterization of CaF\(_{2}\):(Tb\(^{3+}\),Gd\(^{3+}\)) NPs. Fabricated in a wet-chemical procedure, the spherical NPs with a diameter of 5-10 nm show a crystalline structure. Simultaneous doping of the NPs with different lanthanide ions, leading to paramagnetism and fluorescence, makes them suitable for MR and PL imaging. Owing to the Gd\(^{3+}\) ions on the surface, the NPs reduce the MR T\(_{1}\) relaxation time constant as a function of their concentration. Thus, the NPs can be used as a MRI CA with a mean relaxivity of about r = 0.471 mL·mg\(^{-1}\)·s\(^{-1}\). Repeated MRI examinations of four different batches prove the reproducibility of the NP synthesis and determine the long-term stability of the CAs. No cytotoxicity of NP concentrations between 0.5 and 1 mg·mL\(^{-1}\) was observed after exposure to human dermal fibroblasts over 24 h. Overall this study shows, that the CaF\(_{2}\):(Tb\(^{3+}\),Gd\(^{3+}\)) NPs are suitable for medical imaging.},

  abstract  = {The development of novel fibrous biomaterials and further processing of medical devices is still challenging. For instance, titanium(IV) oxide is a well-established biocompatible material, and the synthesis of TiO\(_x\) particles and coatings via the sol-gel process has frequently been published. However, synthesis protocols of sol-gel-derived TiO\(_x\) fibers are hardly known. In this publication, the authors present a synthesis and fabrication of purely sol-gel-derived TiO\(_x\) fiber fleeces starting from the liquid sol-gel precursor titanium ethylate (TEOT). Here, the α-hydroxy-carboxylic acid lactic acid (LA) was used as a chelating ligand to reduce the reactivity towards hydrolysis of TEOT enabling a spinnable sol. The resulting fibers were processed into a non-woven fleece, characterized with FTIR, \(^{13}\)C-MAS-NMR, XRD, and screened with regard to their stability in physiological solution. They revealed an unexpected dependency between the LA content and the dissolution behavior. Finally, in vitro cell culture experiments proved their potential suitability as an open-mesh structured scaffold material, even for challenging applications such as therapeutic medicinal products (ATMPs).},
