Klaumünzer M., Münzel C., Burger A., Voigt M., Spiecker E., Hirsch A., Peukert W., University Erlangen-Nürnberg, DE
In order to optimizing electron transfer and optoelectronic properties in nanoparticulate thin films for electronics we report on an efficient and fast method for surface functionalizing semiconducting metal oxide nanoparticles in liquid phase using a [...]
Nanostructuring of dielectric surfaces induced by KrF excimer laser radiation: Experiment and theory
Nanostructures as well as nanoparticles have a large field of application and a growing economic importance. However, the fabrication of nanostructures poses a big challenge. One promising approach is the usage of laser methods, which [...]
Innovative Use of Ultrasound in the Production of High-Performance Coatings
The metal oxide nanoparticles include nano-sized zinc oxide, titanium oxide, iron oxide, zirconium oxide and cerium oxide, as well as mixed metal compounds, such as indium tin oxide, zirconium and titanium. For the color, paint [...]
Injectable Glucan/Alginate/poly(γ-glutamic acid) Gel for Bone Formation and Differentiation
Aqueous mixture of β-glucan, alginate and calcium form poly(γ-glutamic acid)(Ca-PGA) was compared with the traditional hydrogels cross-linking with calcium chloride and sodium form γ-PGA (Na-PGA). The suitable proportion by investigating the characters of swellability, pH [...]
Modelling the spectral reflectances of Sol-Gel tin doped indium oxide and aluminium doped zinc oxide coatings
In this work it is shown that it is possible to model the spectral reflectances of tin doped indium oxide (ITO) and aluminium doped zinc oxide (AZO) Sol-Gel functional layers with different numbers of single [...]
Highly Stable and Oppositely Charged Hybrid Nanoparticles/Tubes. Fine Tuning of Electro-steric interactions To Fabricate Functional Surfaces
Sekar S., Feltrin E., Giermanska J., Berret J.-F., Chapel J.-P., Centre de Recherche Paul Pascal, FR
Hybrid Functional Surfaces were generated via the novel surface functionalization pathway named Surface Grown Layers (SgL),where the hybrid layers are generated in a single step at a fluid/solid interface via fine tuning of electrostatic complexation [...]
